+
+Preface
+
+
+Within recent years fairly exhaustive studies have been made on many
+aspects of American science and technology. For example, there have been
+numerous works relating to clocks and clockmakers, so that the collector
+and horological student have a number of useful sources on which to
+rely. More recently there has been a series of publications on the
+development of American tools and their makers. Until now, however, no
+systematic study has been attempted of the scientific instruments used
+in the United States from its colonial beginnings. While several useful
+regional lists of instrument makers in early America have been compiled
+from advertisements in contemporary newspapers and published as short
+articles, these, however, are fragmentary, and are inadequate to the
+need for documentation in this field.
+
+With the rapidly growing interest in the history of science, it becomes
+necessary to have a more complete background for the student and the
+historian alike. It is desirable to have a more comprehensive picture of
+the work of the scientific practitioners of the earlier periods of
+American scientific development, and of their tools. At the same time it
+is essential to have a history of the development and distribution and
+use of scientific instruments by others than the practitioners and
+teachers. The role of the instrument maker in the American Colonies was
+an important one--as it was in each epoch of the history of science in
+Europe--and it deserves to be reported.
+
+To make a comprehensive study of American scientific instruments and
+instrument makers in the American Colonies is no simple matter, partly
+because of an indifference to the subject in the past, and partly
+because of the great volume of sources that must be sifted to accomplish
+it. Such a project would require an organized search of all published
+reference works relating to the field and associated topics, of all
+contemporary newspapers for advertisements and notices, of civil records
+filed in state and community archives, of business account-books and
+records that have been preserved, and of business directories of the
+period under consideration. In addition, such a study would require the
+compilation of an inventory of all surviving instruments in private and
+public collections, and a correlation of all the data that could be
+assembled from these sources.
+
+The present study attempts only in part to accomplish this aim, being no
+more than a preliminary compilation of the scientific instruments known
+to have been used during the first two centuries of American colonial
+existence. It merely attempts to assemble all the data that is presently
+available in scattered sources, and to organize it in a usable form for
+the student and historian of American science. A supplement relating to
+19th-century instruments and instrument makers is in progress.
+
+The most that is hoped for the present work is that it will be of
+temporary assistance, serving to bring forth additional information on
+the subject from sources not previously available or known.

+ EARLY AMERICAN
+ SCIENTIFIC
+ INSTRUMENTS
+
+ _and Their Makers_
+
+
+
+
+_The Tools of Science_
+
+
+Philosophical and Practical Instruments
+
+Development of the sciences in the American Colonies was critically
+dependent upon the available tools--scientific instruments--and the men
+who made and used them. These tools may be separated into two groups.
+The first group consists of philosophical instruments and scientific
+teaching apparatus produced and employed for experimentation and
+teaching in educational institutions. The second includes the so-called
+"mathematical instruments" of practical use, which were employed by
+mathematical practitioners and laymen alike for the mensural and
+nautical needs of the Colonies. It is particularly with this second
+group that the present study is concerned.
+
+It has been generally assumed that scientific instruments, as well as
+the instrument makers, of the first two centuries of American
+colonization were imported from England, and that the movement declined
+by the beginning of the 19th century with the development of skilled
+native craftsmen.[1] This assumption is basically true for those
+instruments grouped under philosophical and scientific apparatus for
+experimentation and teaching. Almost all of these items were in fact
+imported from England and France until well into the 19th century.
+
+Likewise, the very earliest examples of mathematical instruments for
+surveying and navigation in the Colonies were imported with the settlers
+from England. It was not long after the establishment of the first
+settlements, however, that the settlers, and later the first generation
+of native Americans, began to produce their own instruments. Records
+derived from historical archives and from the instruments themselves
+reveal that a considerable number of the instruments available and used
+in the Colonies before 1800 were of native production. Apparently,
+relatively few instrument makers immigrated to the American continent
+before the end of the Revolutionary War. Later, with the beginning of
+the 19th century, makers of and dealers in instruments in England and
+France became aware of the growing new market, and emigrated in numbers
+to establish shops in the major cities of commerce in the United States.
+
+Quite possibly the few instrument makers trained in England who
+immigrated to the Colonies in the early epoch of Colonial development
+may have in turn trained others in their communities, although no
+evidence has yet been found. Perhaps more data on this aspect of the
+subject will eventually come to light.
+
+There is reason to believe that a few mathematical practitioners and
+instrument makers lived and worked in the New England colonies as early
+as the first century of colonization.
+
+The evidence, frankly meager, consists of two items. The first is a
+reference relating to James Halsie of Boston. In a land deed made out to
+him in 1674 he was referred to as a "Mathematician."[2] Halsie was
+listed as a freeman of the Massachusetts Bay Colony in 1690. He
+apparently was the forbear of the several members of the Halsy family of
+instrument makers of Boston of the 18th century, mentioned later in this
+study. It is uncertain whether the use of the term "mathematician" in
+this connection meant an artisan, but if not it may be inferred that
+Halsie was a practitioner.
+
+The second piece of evidence is even more slender; it consists of an
+inscription upon a dialing rule (fig. 1) for making sundials and charts.
+The instrument is of cast brass, 20-7/16 inches long and 1-11/16 inches
+wide. The date "1674" is inscribed on the rule together with the name of
+its original owner, "Arthur Willis." The instrument almost certainly was
+produced by the school of Henry Sutton, the notable English instrument
+maker who worked in Threadneedle Street in London from about 1637
+through 1665. The name and date inscriptions are consistent and
+contemporary with the workmanship of the rule, and were probably
+inscribed by the maker for the original owner. It is conceivable that
+Arthur Willis was an Englishman and that the rule was brought into this
+country even in relatively recent times. However, it is claimed that the
+rule was owned and used by Nathaniel Footes, surveyor of Springfield,
+Massachusetts. Nathaniel Footes, believed to have been originally from
+Salem, subsequently moved from Springfield to Wethersfield, Conn. The
+instrument was later owned and used in Connecticut not later than the
+early 19th century[3] by the forbears of Mr. Newton C. Brainard of
+Hartford, Connecticut. If records relating to Willis as a resident of
+the New England colonies can be recovered, it may then be possible to
+establish whether he worked in the Colonies as a mathematical
+practitioner in the 17th century. His name is included on a tentative
+basis.

+
+
+The Need for Instruments
+
+The production and use of scientific instruments in the American
+Colonies reflected colonial development in education and in territorial
+and economic expansion, and closely paralleled the same development in
+England, where the first mathematical practitioners were the teachers of
+navigational and commercial arithmetic and the surveyors employed in the
+redistribution of land following the dissolution of the monasteries. As
+the communities became established and the settlers gained a foothold on
+the soil, their attention naturally turned to improving their lot by
+expanding the land under cultivation and by trading their products for
+other needs. The growth of the communities became increasingly rapid
+from the end of the 17th century, and the land expansion closely
+paralleled the development of trade. The educational institutions placed
+greater emphasis on the sciences as their curriculums developed.
+Particularly there was a greater preoccupation with the sciences on the
+part of the layman because of the need for knowledge of surveying and
+navigation.
+
+The colonial school curriculum was accordingly designed from the
+practical point of view to emphasize practical mathematics, and there
+was an increasing demand for instruction in all aspects of the subject.
+One of the earliest advertisements of this nature appeared in _The
+Boston Gazette_ in March 1719. In the issue of February 19 to March 7
+the advertisement stated that:
+
+ This day Mr. Samuel Grainger opens his school at the House formerly
+ Sir Charles Hobby's, where will be taught Grammar Writing after a
+ free and easy manner in all the usual Hands, Arithmetick in a
+ concise and Practical Method, Merchants Accompts, and the
+ Mathematicks.
+
+ He hopes that more thinking People will in no wise be discouraged
+ from sending their children thither, on the account of the reports
+ newly reviv'd, because these dancing Phaenomena's were never seen
+ nor heard of in School Hours.
+
+The advertisement was further amplified in its second appearance, in the
+issue of March 21-22, 1719:
+
+ At the house formerly Sir Charles Hobby's are taught grammar,
+ writing, after a free & easy manner in all hands usually practiced,
+ Arithmetick Vulgar and Decimal in a concise and Practical Method,
+ Merchants Accompts, Geometry, Algebra, Mensuration, Geography,
+ Trigonometry, Astronomy, Navigation and other parts of the
+ Mathematicks, with the use of the Globes and other Mathematical
+ Instruments, by Samuel Grainger.
+
+ They whose business won't permit 'em to attend the usual School
+ Hours, shall be carefully attended and Instructed in the Evenings.
+
+R. F. Seybold[4] has noted that: "In advertisements of 1753 and 1754,
+John Lewis, of New York City, announced 'What is called a New Method of
+Navigation, is an excellent Method of Trigonometry here particularly
+applied to Navigation; But it is of great use in all kinds of measuring
+and in solving many Arithmetical Questions.' James Cosgrove, of
+Philadelphia, in 1755, taught 'geometry, trigonometry, and their
+application in surveying, navigation, etc.,' and Alexander Power, in
+1766, 'With their Application to Surveying, Navigation, Geography, and
+Astronomy'." These subjects were featured also in the evening schools of
+the colonial period, maintained by private schoolmasters in some of the
+larger communities for the education of those who could not attend
+school in the daytime.
+
+According to Seybold, surveying and navigation were the most popular
+mathematical subjects taught. Some explanation is to be derived from the
+statement by Schoen[5] that: "In the days when the 'bounds' of great
+wilderness tracts were being marked off by deep-cut blazes in the trees
+along a line, a knowledge of land surveying was a useful skill, and many
+a boy learned its elements by following the 'boundsgoer' in his work of
+'running the line.' And those who did not actually take part in running
+the line must have attended many a gay springtime 'processioning' when
+neighbors made a festive occasion out of 'perambulating the bounds'."
+"Vague land grants and inaccurate surveys," he adds, "made the subject
+of boundary lines a prime issue in the everyday life of colonial homes."
+
+At the same time there was interest in the other aspects of the
+mathematical sciences. As early as 1743, for instance, a Harvard
+mathematician named Nathan Prince advertised in Boston that if he were
+given "suitable Encouragement" he would establish a school to teach
+"Geography and Astronomy, With the Use of the Globes, and the several
+kinds of Projecting the Sphere" among other things.[6] A decade later,
+Theophilus Grew, professor in the academy at Philadelphia which has
+become the University of Pennsylvania, published a treatise on globes,
+with the title:
+
+ _The Description_ and _Use_ of the _Globes_, Celestial and
+ Terrestrial; With Variety for _Examples_ for the Learner's
+ _Exercises_: Intended for the Use of Such Persons as would attain
+ to the Knowledge of those _Instruments_; But Chiefly designed for
+ the _Instruction_ of the young _Gentlemen_ at the _Academy_ in
+ Philadelphia. To which is added Rules for working all the Cases in
+ Plain and Spherical Triangles without a Scheme. By _Theophilus
+ Grew_, Mathematical Professor. Germantown, Printed by Christopher
+ Sower, 1753.[7]
+
+Thus, the need for practical mathematical instruments for the surveyor
+and navigator became critical in proportion to the need for men to make
+and use them, and it is not surprising to discover that the majority of
+the instruments produced and advertised by early American makers were
+for surveying, with nautical instruments in second place. Generally, the
+surveyors were not professionals; they were farmers, tradesmen, or
+craftsmen with a sound knowledge of basic arithmetic and occasionally
+with some advanced study of the subject as taught in the evening
+schools. The surveying of provincial and intercolonial boundaries
+required greater skill, however, as well as a knowledge of astronomy,
+and this work was relegated to the scientific men of the period.
+
+As the increasing preoccupation with subdivision of land and with
+surveying led to a greater demand for suitable instruments, it was the
+skilled craftsmen of the community, such as the clockmaker and the
+silversmith, that were called upon to produce them. Superb examples also
+were produced by the advanced scientific men, or "mathematical
+practitioners," of the period.
+
+
+Colonial Training in Instrument Making
+
+One may well ask, where did these native craftsmen acquire the knowledge
+that enabled them to produce so skillfully the accurate and often
+delicate mathematical instruments? There were a number of possible
+sources for this knowledge. The first source lies in England, where some
+of these craftsmen could have studied or served apprenticeships. After
+completing their apprenticeship with English mathematical practitioners,
+they may have immigrated to the Colonies and taught the craft to others.
+This seems to be entirely plausible, and was probably true, for example,
+of Thomas Harland the clockmaker, Anthony Lamb, and perhaps several
+others. However, these were the exceptions instead of the rule, since a
+biographical study of the instrument makers in general reveals that they
+were for the most part native to America. It is not likely that the one
+or two isolated practitioners that had been trained in England could
+have taught so many others who worked in the same epoch.
+
+[Illustration: Figure 2.--Title page of _The Surveyor_ by Aaron
+Rathborne, published in London in 1616. The book was one of the sources
+of information for American makers of mathematical instruments.]
+
+Another source for this knowledge of instrument making was probably the
+reference works on the subject that had been published in England and in
+France. As an example, Nicolas Bion's _Traitè de la Construction et des
+Principaux Usages des Instruments de Mathematique_, which had been first
+published in 1686, was translated into English by Edmund Stone in 1723,
+and went into several English editions. Copies of this work in English
+undoubtedly found their way to America soon after publication. Other
+popular works were Aaron Rathbone's _The Surveyor_, which appeared in
+London in 1616 (see fig. 2); William Leybourn's _The Compleat Surveyor_,
+in 1653; and George Atwell's _Faithfull Surveyour_, in 1662. Other works
+popular in the Colonies were R. Norwood's _Epitome, or The Doctrine of
+Triangles_ (London, 1659) and J. Love's _Geodasia, or the Art of
+Surveying_ (London, 1688).
+
+These works undoubtedly inspired similar publications in America, for
+many books on surveying and navigation appeared there before the
+beginning of the 19th century. Chief among them were S. Moore's _An
+Accurate System of Surveying_ (Litchfield, Conn., 1796), Z. Jess's _A
+Compendious System of Practical Surveying_ (Wilmington, 1799), Abel
+Flint's _Surveying_ (Hartford, 1804), and J. Day's _Principles of
+Navigation and Surveying_ (New Haven, 1817).
+
+The published works were unquestionably responsible for much of the
+training in the making of mathematical instruments in America, although
+no documentary evidence has yet been recovered to prove it.
+
+Another important influence on early American instrument-making which
+must be noted was that of the clockmaker as an artisan. A comprehensive
+study of surviving instruments and related records has revealed that
+only a few of the many clockmakers working in the American Colonies in
+the 18th century made mathematical instruments. Yet, a large proportion
+of the surviving surveying and nautical instruments produced before 1800
+were the work of clockmakers. Classic among these must be noted the
+instruments produced by the brothers David and Benjamin Rittenhouse (see
+p. 15 and figs. 3 and 4), as well as the fine surveying instruments made
+by four separate members of the Chandlee family, whose clockmaking
+traditions began early in the 17th century (see p. 54).
+

+Society.]
+
+[Illustration: Figure 4.--Surveying compass marked "Potts and
+Rittenhouse." Believed to be the work of David Rittenhouse in
+partnership with Thomas Potts. Photo courtesy the American Philosophical
+Society.]
+
+Finally, one must not overlook the fact that examples of English and
+other European instruments were available in the Colonies, and that at
+least some of the early colonial makers undoubtedly copied them. It is
+apparent from some surviving early American instruments that the
+materials, designs, dimensions, and details of European prototypes had
+been deliberately copied. It is possible to see in public collections,
+for instance, a Davis quadrant of English manufacture exhibited beside a
+later example, signed by a New England maker, which comes
+extraordinarily close to duplicating it in every feature.
+
+As with the presumed influence of published works, the practice of
+copying imported instruments cannot be documented, but it must have been
+engaged in by many of the unschooled New England instrument makers. By
+this means some may even have profited to the degree that they became
+professional craftsmen without benefit of formal apprenticeship.
+
+Yet it is remarkable that although numerous instruments were produced by
+native artisans, in addition to the substantial number which were
+imported before the end of the 18th century, relatively few specimens
+have survived in public collections as well as in private hands. Despite
+the exhaustive combing of attics and barns throughout the country by
+dealers in antiques and by avid collectors during the past several
+decades, the number of surviving instruments now known is incredibly
+small in comparison with the numbers known to have been made locally or
+imported before the beginning of the 19th century. Since instruments are
+not items which would ordinarily be deliberately discarded or destroyed,
+or melted down for the recovery of the metal, this small percentage of
+survival presents a puzzle which has not been resolved.

+
+
+_The Mathematical Practitioners_
+
+
+The Rittenhouse Brothers
+
+Notable among the American practitioners was David Rittenhouse
+(1732-1796) of Norristown and Philadelphia, Pennsylvania, who was
+established as a clockmaker and surveyor in Philadelphia by 1749. He
+surveyed the boundary between Pennsylvania and Delaware in 1763 with
+instruments of his own design and construction. Six years later, in
+1769, he successfully calculated the transit of Venus and later
+observed that planet with astronomical instruments he had constructed
+himself. In the following year, 1770, he built the first American
+astronomical observatory, in Philadelphia. Two orreries that he designed
+and built--at the University of Pennsylvania and at Princeton
+University--survive as outstanding examples of American craftsmanship.[8]
+Several of his surveying and astronomical instruments are exhibited in the
+collections of the U.S. National Museum. David Rittenhouse is credited
+with being the originator of a declination arc on the surveying compass,
+a feature to be copied by a number of later instrument makers.
+
+David's brother, Benjamin Rittenhouse (1740-c.1820), served in the
+Revolution and was wounded at Brandywine. He superintended the
+Government's gunlock factory at Philadelphia in 1778 and achieved
+recognition as a maker of clocks and surveying instruments (see fig.
+8).[9] During one period of his career he worked in partnership with his
+brother David. An interesting advertisement appeared in the May 14,
+1785, issue of _The Pennsylvania Packet_:
+
+ WANTED, An ingenious Lad not exceeding 14 years of age, of a
+ reputable family, as an Apprentice to learn the Art and Mistery of
+ making Clocks and Surveying Instruments. Any lad inclining to go an
+ apprentice to the above Trade, the terms on which he will be taken
+ may [be] known by enquiring of Mr. David Rittenhouse, in
+ Philadelphia, or at the subscriber's house in Worcester township,
+ Montgomery county. Benjamin Rittenhouse.

+
+
+Andrew Ellicott
+
+A name closely associated with that of the Rittenhouse brothers was that
+of Andrew Ellicott (1754-1820) of Solebury, Pennsylvania, and Ellicotts
+Mills, Maryland. Andrew was the son of Joseph Ellicott, the clockmaker
+and pioneer industrialist who founded Ellicotts Mills. Although a
+Quaker, Andrew (fig. 9) served in the Revolution, and he became one of
+the most distinguished engineers of the new republic. He worked as a
+clockmaker and instrument maker from 1774 to 1780. In 1784 he ran the
+boundary between Virginia and Pennsylvania and in the following year he
+was a member of the survey that continued Mason and Dixon's line. In
+1785 and 1786 he served on the Pennsylvania commissions that surveyed
+the western and northern boundaries of the state, and in 1789 he served
+on the commission that fixed the boundary between New York and
+Pennsylvania. Between 1791 and 1793 he surveyed the site of the city of
+Washington, D.C., and redrew L'Enfant's plan for the city.
+
+In early 1793 Ellicott was appointed commissioner by the Commonwealth of
+Pennsylvania for the project of viewing and locating a road from Reading
+to Presque Isle, now Erie. It was an extremely difficult undertaking,
+but Ellicott completed the work by the autumn of 1796, including laying
+out the towns of Erie, Warren, and Franklin.
+
+In May 1796 Ellicott was commissioned by President Washington to survey
+and mark the boundary line between the United States and the Spanish
+Province of Florida in accordance with the provisions of the
+Pinkney-Godoy Treaty of October 27, 1795. This line was to begin at the
+point where the 31st parallel of north latitude intersected the
+Mississippi River, and to proceed thence along that parallel eastward to
+the Appalachicola River for about 400 miles.
+
+In 1801 Ellicott was offered the position of surveyor general of the
+United States by President Jefferson. Ellicott declined, but
+subsequently accepted the secretaryship of the land office of
+Pennsylvania, a post he held until 1808.
+
+In 1811 Ellicott became commissioner to represent Georgia in locating
+the Georgia-North Carolina boundary, a project on which he was engaged
+for the major part of the following year.
+
+In 1815 President Madison appointed Ellicott professor of mathematics at
+West Point, with the rank of major. This is an appointment he kept until
+his death in 1820. It was interrupted in 1817 when the Government
+required his services as astronomer to locate a portion of the United
+States-Canadian boundary in accordance with the fifth article of the
+Treaty of Ghent.

+
+Ellicott was a member of a number of learned societies, including the
+American Philosophical Society, the Society for the Promotion of Useful
+Arts of Albany, and of the National Institute of France.
+
+Ellicott constructed a number of instruments for surveying and
+astronomical observation, and he designed and used others that were
+produced by his friend David Rittenhouse[10] (see figs. 10, 11). Of
+particular interest in connection with Ellicott's career as a clockmaker
+and instrument maker are two advertisements that appeared in the
+Baltimore newspapers. The first one was in the _Maryland Journal and
+Baltimore Daily Advertiser on April 7, 1778_:
+
+ Ellicott's Upper Mills, April 4, 1778. Wanted, a person acquainted
+ with the Clock-Making business, and able to work by directions.
+ Such a person will meet with good encouragement by applying to
+ Andrew Ellicott, sen.
+
+The second advertisement, in the same vein, appeared in the May 16,
+1780, issue of the _Maryland Journal_:
+
+ Good Encouragement will be given to either Clock or Mathematical
+ instrument makers, by the subscriber, living in Baltimore-Town.
+ Andrew Ellicott.
+
+
+Owen Biddle
+
+Another mathematical practitioner associated with David Rittenhouse in
+his observations of the transit of Venus was Owen Biddle (1737-1799) of
+the North Ward, Philadelphia.
+
+In early life Biddle was an apothecary and a clock and watchmaker. In
+his shop "next door to Roberts warehouse" he sold clock and watch parts
+and tools. From 1764 to 1770 he advertised himself as "Clockmaker, and
+scientist, statesman and patriot." As a Quaker, he participated actively
+in civic and patriotic affairs of Philadelphia. During the American
+Revolution, in spite of his religious affiliation, he fought for the
+defense of the Colonies and was appointed Deputy Commissioner of Forage.
+Evidencing sincere repentance, he was permitted to rejoin the Society of
+Friends.
+
+In 1769 Biddle took an active part in the preparations made by the
+American Philosophical Society for the observation of the transit of
+Venus. With Joel Baily he was sent to Cape Henlopen, Delaware, with a
+large reflecting telescope borrowed from the Library Company. The
+expedition was described in the _Transactions of the American
+Philosophical Society_ in 1771 in an article entitled "An Account of the
+Transit of Venus, over the Sun's Disk, as observed near Cape Henlopen,
+on Delaware Bay, June 3rd, 1769 by Owen Biddle, Joel Baily and (Richard
+Thomas) Drawn by Owen Biddle." In addition to his trade in clocks and
+watches, Biddle also made mathematical instruments and was well known in
+his native city as a merchant, inventor, and ironmaster.
+
+
+Benjamin Banneker
+
+A name that is too often ignored in the history of science in colonial
+America is that of a free Negro, Benjamin Banneker (c. 1734-1806) of
+Baltimore. A farmer by occupation, Banneker was the son of a native
+African slave and a free mulatto woman. In his spare time he attended
+the school of a Quaker farmer; the only book he owned was the Bible.
+When he was a young man he acquired a watch from a trader, and from it
+he developed his love of science and instruments. Although he had never
+seen a clock, he constructed one based on drawings he made from the
+watch. Banneker was called upon to assist in the construction of the
+mills for the Ellicotts, and it was natural that his clock, which was
+the marvel of the Negro settlement, should come to the attention of
+Joseph Ellicott. Ellicott became interested in Banneker's thirst for
+knowledge and allowed him the use of his tools, scientific instruments,
+and technical books. Among the books were Mayer's _Tables_, James
+Ferguson's _Astronomy_, and Leadbeater's _Lunar Tables_. Banneker
+absorbed these and other works that he borrowed and went on to explore
+the wonderful new world they opened up for him. He pursued astronomical
+studies, and within three years he began to make calculations (fig. 12)
+for an almanac. After completing the calculations for the year 1791, he
+went on to produce a set of calculations for 1792. During this period he
+mastered the use of surveying instruments and made a firsthand study of
+tides in the region. His great opportunity came when Andrew Ellicott was
+chosen to make a survey for the city of Washington and hired Banneker as
+an assistant. While thus employed, Banneker completed his almanac and
+gave it to George Ellicott, Andrew's cousin, as a subject of possible
+interest. Apparently George Ellicott turned it over to the Honorable
+James McHenry of Baltimore, who in turned submitted it to the
+Philadelphia firm of Goddard & Angell, who published it (fig. 13).
+Banneker mailed a copy of his _Benjamin Banneker's Pennsylvania,
+Delaware, Virginia And Maryland Almanac and Ephemeris For the Year of
+Our Lord, 1792_ to Thomas Jefferson, who was so impressed with it that
+he forwarded it to the Marquis de Condorcet, secretary of the French
+Academy of Sciences. After his work with Ellicott had been completed,
+Banneker retired to his farm to produce almanacs annually until 1802.
+When he died in 1806 he was eulogized before the French Academy by the
+Marquis de Condorcet, and William Pitt placed his name in the records of
+the English Parliament.[11]
+

+Ellicott dated October 13, 1789, regarding astronomical data for the
+compilation of Banneker's almanac. Photo courtesy Maryland Historical
+Society.]
+
+
+Joel Baily
+
+Still another 18th-century practitioner was Joel Baily (1732-1797), a
+Quaker of West Bradford, Pennsylvania. In addition to his trade as a
+clockmaker and gunsmith, Baily achieved local eminence as an astronomer,
+mathematician, and surveyor.[12]
+
+In 1764, at the time that Charles Mason and Jeremiah Dixon established
+their headquarters near his farm, Baily was the local surveyor.
+Obtaining employment with the expedition, he worked with Mason and Dixon
+until the completion of their survey in 1768. Baily was subsequently
+employed by Mason and Dixon to build pine frames for carrying the
+20-foot rods to be used in the second measurement of courses from the
+Stargazers' Stone southward.
+
+In 1769 Baily was appointed by the American Philosophical Society to
+work with Owen Biddle in setting up the station at Cape Henlopen for
+observation of the transit of Venus. In 1770 he again worked with Biddle
+in taking the courses and distances from the New Castle Court House to
+the State House Observatory in Philadelphia for determining the latitude
+and longitude of each. In the same year Baily was elected a member of
+the American Philosophical Society.
+
+
+Reverend John Prince
+
+Another noteworthy mathematical practitioner of the period was the
+Reverend John Prince (1751-1836) of Salem, Massachusetts. The son of a
+hatter and mechanic, Prince studied natural philosophy under John
+Winthrop at Harvard and received his B.A. degree in 1776. He was a
+student of divinity under Samuel Williams and was ordained in 1779 at
+the First Church in Salem. Although an amateur of the sciences, Prince
+became a skilled maker of scientific instruments. He made, sold, and
+repaired instruments for the use of numerous colleges, schools, and
+academies, including Brown, Dartmouth, Rutgers, Harvard, Union, Amherst,
+and Williams. Among other accomplishments, he effected "improvements" on
+the lucernal microscope and the air pump.[13]
+
+[Illustration: Figure 13.--Title page of one of Banneker's almanacs. The
+portrait of Banneker was made by Timothy Woods in 1793 for the publisher
+and reproduced by woodcut. Banneker's first almanac was published in
+Philadelphia in 1792.]
+
+
+Amasa Holcomb
+
+Although he was born in the 18th century, Amasa Holcomb (1787-1875)
+properly belongs to a later period. An astronomer and telescope maker of
+Southwick, Massachusetts, Holcomb became a surveyor in 1808. An
+autobiographical sketch noted that "he manufactured about this time a
+good many sets of surveyors instruments--compasses, chains, scales,
+protractors and dividers, some for his pupils and some for others."[14]
+
+
+
+
+Instruments of Metal
+
+
+Pre-Revolutionary Immigrant Makers
+
+According to present evidence, only a few makers of metal instruments
+emigrated from England to the Colonies before the beginning of the
+Revolutionary War. A slightly larger number emigrated after the war had
+ended. In almost every instance, the immigrant instrument makers settled
+in the major cities, which were the shipping centers of the new country.
+The reason is obvious: in these cities there was the greatest demand for
+nautical and other instruments.
+
+One of the earliest immigrant instrument makers arrived in Boston in
+1739. According to an advertisement that appeared in _The Boston
+Gazette_ in the issue of July 16-23, 1739, there had
+
+ Arriv'd here by Capt. _Gerry_ from _London_ John Dabney, junr. who
+ serv'd his time to Mr. Jonathan Sisson, Mathematical Instrument
+ Maker to his Royal Highness, the Prince of Wales. Makes and sells
+ all sorts of Mathematical Instruments, in Silver, Brass, or Ivory,
+ at Reasonable Rates, at Mr. Rowland Houghton's Shop the north side
+ of the Town Huse in Boston.
+
+ N.B. Said Dabney, sets Loadstones to a greater Perfection than any
+ heretofore.
+
+Dabney's master, Jonathan Sisson (1694-1749) originally of Lincolnshire,
+with a shop in the Strand, London, was a well-known maker of optical and
+mathematical instruments in the early decades of the 18th century. He
+was particularly noted for the exact division of scales, and examples of
+his work are to be found in the major collections.
+
+Dabney's name appeared again several years later, in the Supplement to
+the _Boston Evening Post_ for December 12, 1743, and again in the
+_Boston Evening Post_ for December 19 of the same year, with the
+following advertisement:
+
+ To be shown by John Dabney, Mathematical Instrument maker, in Milk
+ Street, Boston, on Monday, Tuesday and Thursday Evenings, from five
+ to eight o'clock, for the Entertainment of the Curious, the Magic
+ Lanthorn an Optick Machine, which exhibits a great Number of
+ wonderful and surprising Figures, prodigious large, and vivid, at
+ Half a Crown each, Old Tenor.
+
+In New York City, one of the earliest immigrant instrument makers was
+Charles Walpole, who established a shop at a corner in Wall Street,
+according to a notice in the May 26, 1746, issue of the _New York
+Evening Post_. The announcement stated that Walpole was a "citizen of
+London" and that at his shop "all sorts of Mathematical Instruments,
+whether in silver or brass, are made and mended...."
+
+In the May 21, 1753, issue of _The New York Gazette or The Weekly Post
+Boy_ there was an announcement by the widow of Balthaser Sommer who
+lived on Pot-Baker's Hill in Smith Street in New York City and who
+advertised herself as a "grinder of all sorts of optic glasses, spying
+glasses, of all lengths, spectacles, reading glasses for near-sighted
+people or others; also spying glasses of 3 feet long which are to set on
+a common Walking-Cane and yet be carried as a Pocket-Book."
+
+John Benson emigrated from Birmingham, England, and established a
+lapidary and optical store in May 1793 at 12 Princess Street in New
+York, where he produced miniatures, lockets, rings, glasses, "as well as
+Spectacles, single reading and burning glasses, and where he also
+polished scratch'd glasses." In July 1797 he moved to 106 Pearl Street
+where he sold green goggles, thermometers, and opera and spy glasses, in
+addition to an assortment of jewelry. In September 1798 he was
+established at a new location, 147 Pearl Street, "At the sign of The
+Green Spectacles" where he specialized in optical goods. He featured for
+rent or sale a "Portable Camera Obscura" for the use of artists in
+drawing landscapes. His advertisements chronicled each change in
+location in the issues of _The New York Daily Advertiser_.
+
+A craftsman whose name is well known in scientific circles was Anthony
+Lamb, who advertised in 1753 as a mathematical instrument maker living
+on Hunter's Key, New York. He claimed that he could furnish
+
+ Godfrey's newly invented quadrant, for taking the latitude or other
+ altitudes at sea; hydrometers for trying the exact strength of
+ spirits, large surveying instruments in a more curious manner than
+ usual; which may be used in any weather without exception, small
+ ditto which may be fixed on the end of a walking stick, and
+ lengthened to a commodious height, gauging instruments as now in
+ use, according to an act of assembly with all other mathematical
+ instruments for sea or land, by wholesale or retail at reasonable
+ rates.[15]
+
+Lamb had served an apprenticeship with Henry Carter, a mathematical
+instrument maker in London. In July 1724 he became an accomplice of
+Jack Sheppard, a notorious burglar, and was arrested and sentenced to
+the gallows in 1724. As he was awaiting execution on the gallows at
+Tyburn, his sentence was commuted to transportation to Virginia for a
+period of seven years, inasmuch as this was his first offence. After he
+had completed his term of seven years in Virginia he moved to
+Philadelphia, where he opened a shop as an instrument maker and a
+private school for teaching technical subjects. The curriculum included
+surveying, navigation, and mathematics. Although his enterprises
+prospered, he moved to New York. There he married a Miss Ham and
+established himself in a respectable position. Lamb's first
+advertisement in New York appeared on January 23, 1749. He died on
+December 11, 1784, at the age of 81, and two days later he was eulogized
+in _The New York Packet_ where he was mentioned as "a steady friend to
+the liberties of America."
+
+John Lamb (1735-1800), Anthony's son, learned and practiced his father's
+craft for a time and worked as a partner in the firm of A. Lamb & Son.
+He subsequently became a wine and sugar merchant, achieved considerable
+wealth, married well, and was accepted by the gentry of the city. He was
+a firm patriot and from 1765 he was active as the leader of the Sons of
+Liberty. He served in several major engagements in the American
+Revolution and in 1783 was brevetted a brigadier-general.[16]
+
+The immigrant instrument makers were not confined to those working in
+glass, however. One of the earlier immigrant craftsmen was Charles
+Blundy, a London watchmaker who established himself on Church Street in
+Charleston, South Carolina, in 1753. He notified the public that in
+addition to watches he sold thermometers of all sizes and types.
+Presumably his merchandise was imported from England.[17] He was absent
+from the city between 1753 and 1760 but returned and continued in
+business in the latter year.
+
+Another pre-Revolution immigrant was Thomas Harland (1735-1807), a clock
+maker who settled in Norwich, Connecticut, in 1773. It is claimed that
+he sailed from England on one of the ships carrying the tea destroyed by
+the Boston Tea Party. Over the course of the years his business
+prospered to such a degree that he hired from ten to twelve apprentices
+at one time. Some of the leading American 18th-century clockmakers
+served apprenticeships with Harland. In 1802 his newspaper notice stated
+that he had for sale "Surveyors Compasses, with agate centre needles;
+chains and Protractors ..."[18]
+
+A most interesting instrument that has recently come to light is a brass
+sundial made in Philadelphia in 1764. The dial, about 10-1/2 inches in
+diameter, is signed by the maker, "Daniel Jay Philad^a. fecit." It is
+dated 1764 and inscribed with the name of the person for whom it was
+made, "James Pemberton." In the center is "Lat. 40," which coincides
+with the latitude for Philadelphia. The style of the dial is very much
+in the English tradition of the period, indicating that Jay was probably
+an emigrant trained in England.
+
+
+Post-Revolutionary Immigrant Makers
+
+A large proportion of the English craftsmen who came to the American
+Colonies after the Revolution settled in Philadelphia, There was John
+Gould for instance, a mathematical instrument maker from London who had
+opened a shop at 47 Water Street by 1794. He sold nautical, surveying,
+and optical instruments as well as mirrors, presumably all imported from
+England. He moved to 70 South Front Street "At the Sign of the Quadrant"
+in 1796. He was succeeded in business in 1798 by Thomas Whitney, another
+emigrant from London. Whitney made and sold instruments (see fig. 85) in
+Gould's former shop, and featured also a vast array of department store
+merchandise. John Whitney, who may have been his son, was listed at the
+same address in the Philadelphia directory of 1801 as a "Mathematical
+Instrument Maker and Optician."[19]
+
+In the Philadelphia directory and register for 1821 Thomas Whitney
+advertised that he
+
+ ... presents his sincere thanks to his friends and the public and
+ respectfully soliciting the continuation of their favors, wishes to
+ inform them that he has devoted his attention principally to the
+ making of surveying compasses for 16 years past, and has made 500
+ of them; the good qualities of which are well known to many
+ surveyors, in at least 16 of the States and Territories of the
+ Union ... [he also makes] many other instruments, protractors,
+ gunner's Calibers and quadrants, etc.
+
+George Evans was another instrument maker who arrived from London after
+the end of the Revolution. He established himself in a shop at 33 North
+Front Street in 1796, where he sold imported instruments as well as
+stationery, Bibles, and cloth. He died in 1798.[20]
+
+Thomas Dring, who migrated from England, settled in Westtown Township of
+Chester County, Pennsylvania, where he was first noted in the tax
+records of 1786. He married Hanna Griffith, a native of the region, and
+their son, Jeptha Dring, subsequently was mentioned as a carpenter by
+trade, and a vagrant by inclination, who could quote Shakespeare from
+memory. According to local legend, Dring raised money from a number of
+townspeople for the purpose of purchasing clocks for them in England. He
+set sail for his homeland in about 1798 and never returned.
+
+Although the tax records for 1796 described Dring as an "Optician" he
+was also a clockmaker and maker of scientific instruments. At least
+three of his tall-case clocks have survived, and a stick type of
+barometer which he made for Edward and Hannah Hicks in 1796. The
+instrument is now in the collection of the Chester County Historical
+Society. It measures 39 inches in height, and is signed on the
+thermometer dial THOMAS DRING/West Chester. This instrument (fig. 14) is
+one of the very rare barometers produced in America in the 18th century.
+
+Another craftsman who emigrated from England was Robert Clark, who
+opened a shop at 5-1/2 Church Street in Charleston, South Carolina, in
+1785. In that year he announced himself as a
+
+ Math., Optical and Philosophical Instruments maker and Clockmaker
+ from London ... As the Advertiser has lately had an opportunity of
+ working and receiving instruction under the first masters in the
+ above branches in Great Britain, flatters himself that he shall
+ give satisfaction to those who may be pleased to favor him with
+ their orders ... for Surveyors compasses, Quadrants, Telescopes,
+ Microscopes, Spirit Levels, etc.[21]
+
+W. Fosbrook was another craftsman originally from London. He was a
+cutler and maker of surgical instruments, with a shop in Beekman's Slip
+in New York City in 1786 or earlier. He specialized in leg irons and
+rupture trusses, and he made instruments and files for setting the
+teeth as well as standard items for surgeons.[22]
+
+[Illustration: Figure 14.--Barometer made in 1796 by Thomas Dring of
+West Chester, Pa., for Edward and Hannah Hicks. Photo courtesy the
+Chester County Historical Society.]
+
+Several immigrant instrument makers established themselves in
+Philadelphia during the same period. John Denegan (or Donegan), stated
+to have been "late from Italy," moved his shop in March 1787 to the
+corner of Race and Fourth Streets at "the sign of the Seven Stars".[23]
+There he made barometers and thermometers as well as glasses for
+philosophical experiments. It seems too much of a coincidence that in
+October 1787 an instrument maker named Joseph Donegany established a
+shop at 54 Smith Street in New York City,[24] where--according to an
+advertisement in the October 17, 1787, issue of _The New York Daily
+Advertiser_--he made "thermometers, barometers and sold hydrostatic
+Bubbles and hygrometers for proving spirits, and also ... glasses for
+experimental purposes." It is probable that Denegan and Donegany were
+one and the same; since Denegan was stated to have been of Italian
+origin, the name may originally have been "De Negani."
+
+Joseph Gatty advertised himself as an "Artist from Italy" with a shop at
+341 Pearl Street in New York City where he "made and sold every simple
+and compound form of barometer and thermometer as well as curious
+Hygrometers for assaying spirits which show the actual strength with the
+greatest precision and are not liable to be corroded, in addition to
+several new Philosophical Instruments of his own invention, and all
+types of artificial fireworks."[25] By 1796 Gatty (or Gatti?) had moved
+to Philadelphia where he had a shop at 79 South Front Street and
+advertised the same items that had appeared in his advertisements in New
+York. The Philadelphia directory for 1800 listed Gatty as a "Weather
+Glass Maker."[26]
+
+
+Native American Makers
+
+Comparatively speaking, the greater proportion of the early American
+instrument makers were native born. Among these were to be found a
+substantial number of artisans trained as clockmakers who subsequently
+produced scientific instruments to meet the surveying and nautical needs
+of their communities. Together with the other craftsmen throughout the
+colonies who established and advertised themselves specifically as
+instrument makers, they produced a large number of the mathematical
+instruments used in the American Colonies in the 18th century. A careful
+study of their regional distribution reveals that most of them were
+concentrated in the major coastal cities of commerce.
+
+[Illustration: Figure 15.--James Wilson, first American maker of globes.
+From a sketch by John Ross Dix in _Ballou's Pictorial Drawing Room
+Companion_ (Boston, 1857), vol. 12, p. 156.]
+
+
+_New Hampshire_
+
+Among the artisans who combined clockmaking with instrument making
+before the beginning of the 19th century was Benjamin C. Gilman
+(1763-1835) of Exeter, New Hampshire. He made mathematical instruments
+and clocks in addition to working as a silversmith, clockmaker, and
+hydraulic engineer.
+
+
+_Vermont_
+
+A New England instrument maker who had a most unusual career was James
+Wilson (1763-1855) of Bradford, Vermont. He was a native of Francestown,
+New Hampshire, where he was born in a log cabin and brought up on a
+farm. In 1796 he purchased his own farm, at Bradford.
+
+[Illustration: Figure 16.--Globe made by James Wilson (1763-1855) of
+Bradford, Vermont. Diameter is 13 in. Photo courtesy Houghton Library,
+Harvard University.]
+
+When a young man of 36 he saw a pair of globes at Dartmouth College in
+neighboring Hanover and tried to duplicate them. He made balls of wood
+turned from solid blocks, covered them with paper, and finished them off
+with lines and drawings. He later improved this method by coating the
+wooden balls thickly with layers of paper pasted together. He then cut
+the globes into hemispheres, removed the wooden molds, and joined the
+paper shells to make the globes.
+
+Wilson next proceeded to procure copper plates of the necessary sizes
+for his globes, and he projected his maps on them in sections. He
+received a few lessons in engraving from Amos Doolittle of New Haven,
+but he was otherwise completely self-taught.
+
+Wilson exhibited the first edition of his globes in Boston in 1814. They
+created a sensation, and many persons asked to see the maker, but Wilson
+was reluctant to come forward because of his coarse clothing and rustic
+manners. He was greatly encouraged, however, by the public interest in
+his work, and he continued to make globes in Bradford (see fig. 16). In
+about 1815 Wilson and his three sons, all of whom were as ingenious as
+the father, formed a company to manufacture globes in Albany. There they
+produced terrestrial and celestial globes, the latter showing as many as
+5,000 stars. Wilson produced a new set of plates in 1826 and made globes
+in several sizes. Even after he had reached the age of 83 years he
+constructed an excellent planetarium, engraving the large copperplate
+himself.
+
+Wilson was married three times and was the father of 14 children. He
+died at the age of 92 in March 1855 at Bradford.[27]
+
+
+_Massachusetts_
+
+A surprisingly small number of the Massachusetts craftsmen working
+before the end of the 18th century produced scientific instruments.
+Among the very earliest were several members of the King family of
+Salem. Daniel King (1704-1790) was born in Salem on November 17, 1704.
+At the time of his death Rev. William Bentley spoke of him as a "maker
+of Mathematical Instruments" and a "teacher of Mathematics."[28]
+
+[Illustration: Figure 17.--Brass surveying compass made by Stephen
+Greenleaf (fl. 1745) of Boston. Photo courtesy New Hampshire Historical
+Society, Concord.]
+
+Following Daniel's death, his business in instruments was inherited by
+his son Benjamin King (1740-1804), of Salem. Benjamin specialized in
+producing nautical instruments, and several of his Davis quadrants have
+survived in public collections. When he died on December 26, 1804,
+Reverend Bentley wrote that King was "... a Mathematical Instrument
+maker, in that branch which immediately regarded practical navigation by
+quadrant and compass. He supported a very good character through life &
+was much esteemed."[29]
+
+Another of the very early mathematical instrument makers in
+Massachusetts was Stephen Greenleaf (see fig. 17), who kept a shop on
+Queen Street opposite the prison in Boston where
+
+ He makes and Mends all Sorts of Mathematical Instruments, as
+ Theodolites, Spirit Levels, Semicircles, Circumferences, and
+ Protractors, Horizontal and Equinoctial Sun Dials, Azimuth and
+ Amplitude Compasses, Elliptical and Triangular Compasses, and all
+ sorts of Common Compasses ... N.B. He sets Load Stones on Silver or
+ Brass, after the best manner.[30]
+
+Jonathan Dakin worked as a mathematical balance-maker "at the Sign of
+the Hand & Beam, opposite to Dr. Colman's Meeting House" where he made a
+variety of scale beams in 1745.[31]
+
+An interesting advertisement by Rowland Houghton appeared in the January
+17-24, 1737, issue of the _Boston Gazette_. Houghton announced that he
+had "lately improv'd on his new Theodolite, by which the Art of
+Surveying is rendered more plain & easy than heretofore." Houghton was
+active in the political scene in Boston, as evidenced by the fact that
+in various issues of the _Boston Gazette_ for January and February 1739
+he is listed variously as "Commissioner," "Proprietors' Clerk" and as
+"Collector."
+
+Isaac Greenwood, Jr. (1730-1803), was born at Cambridge, where he
+married Mary I'ams in 1757. He maintained a shop where he combined the
+business of mathematical instrument maker and ivory turner, and also
+imported hardware. After the Revolution, he engaged in dentistry,
+specializing in making artificial teeth and in the manufacture of
+"umbrilloes." Paul Revere apparently did printing for him on five
+different occasions between 1762 and 1774, and in about 1771 engraved
+his trade card, which read:
+
+ ISAAC GREENWOOD, Ivory Turner Next door to Doctor John Clark's at
+ the North End Boston. Turns all sorts of work in Ivory, Silver,
+ Brass, Iron, Horn, Wood, etc. Such as Billiard Balls, Tea Boards,
+ Scallop^d and Plain Salvers, Decanters ...[32]
+
+Isaac's father, Isaac Greenwood, Sr., was "Professor of Mathematicks and
+Natural and Experimental Philosophy" at Harvard. In the _Boston Gazette_
+for February 19-26, 1728, there appeared the following notice of his
+installation:
+
+ On the 13th of this Month at Ten in the Morning, The Honorable &
+ Reverend Overseers of the College at Cambridge, met the Corporation
+ in the College Hall, to Inaugurate Mr. Isaac Greenwood into the
+ Office of Professor of the Mathematicks, and Natural and
+ Experimental Philosophy, lately founded by that great and living
+ Benefactor to this Society, Mr. Thomas Hollis of London Merchant.
+ The Rev. President being detain'd by illness, Mr. Flint the Senior
+ Fellow perform'd the part of Moderator, began with Prayer, and then
+ Pronounc'd a Latin Oration proper to the Occasion: Mr. Wiggleworth
+ Divinity Professor, read the Founders Instructions. Mr. Greenwood
+ took the Oaths and made the Declarations required in them: and
+ pronounc'd a Latin Oration. The Rev. Mr. Appleton Pray'd: and
+ Singing part of the 104 Psalm concluded the Solemnity. After which
+ the Overseers & Corporation repair'd to the Library; till the
+ Publick Dinner in the Hall was ready, where all the Gentlemen
+ Spectators of the Solemnity were hansomely Entertained.
+
+Greenwood continued to teach privately for a decade. In various issues
+of _The Boston Gazette_ of 1738 and 1739 he featured an advertisement,
+the text of which always stated:
+
+ Such as are desirous of learning any Part of Practical or
+ Theoretical Mathematics may be taught by Isaac Greenwood, A.M. &c.
+ in Clark's Square, near the North Meeting House, where Attendance
+ will be given between the Hours of 9 and 12 in the Forenoon, and 2
+ and 5 in the Afternoons.
+
+ N.B. Instructions may also be had in any Branch of Natural
+ Philosophy, when there is a sufficient Number to attend.[33]
+
+John Bailey II (1752-1823) of Hanover and Lynn, Massachusetts worked as
+a clockmaker from about 1770. His father, John Bailey I, and his
+brothers Calvin and Lebbeus also were clockmakers. Bailey married Mary
+Hall of Berwick, Maine, and settled in Hanover where he made scientific
+instruments and clocks. A brass surveying compass in the collection of
+the New York Historical Society is inscribed "J. BAILEY HANOVER
+1804."[34]
+
+Undoubtedly the best known instrument maker in Massachusetts was Joseph
+Pope (1750-1826), of Boston, who was described by contemporaries as the
+"local mathematician, watch-maker and mechanical genius." In 1787 he
+completed the construction of a gear-driven orrery displaying the
+motions of the solar system in a horizontal plane with eccentric and
+inclined orbits. At each of the twelve corners were mounted cast bronze
+figures, claimed to have been carved in wood by Simeon Skillin and cast
+in bronze by Paul Revere. Although the instrument was made for Harvard,
+the university lacked funds for its purchase. Accordingly, it held a
+public lottery which realized a substantial sum in excess of the
+£450.3.0 paid to Pope, and the orrery was delivered in December
+1788.[35] The orrery (fig. 18) has survived and is part of the
+collection of historical scientific instruments at Harvard University.
+
+According to a statement in the _Boston Gazette_ for February 16, 1789,
+an apparatus for displaying planets in their proper orbits by means of
+wires was made and exhibited in Boston by Bartholomew Burges.
+
+Mention must also be made of several members of the Folger family of
+Nantucket, Massachusetts. Peter Folger (1617-1690), founder of the
+American branch of the family, emigrated from Norfolk, England, in 1635
+and occupied himself in Nantucket as blacksmith, schoolmaster,
+watchmaker, and surveyor. He was a grandfather of Benjamin Franklin.
+Another notable descendant was Maria Mitchell (1818-1889), professor of
+astronomy and director of the observatory at Vassar College.
+
+The best known member of the family was Walter Folger, Jr. (1765-1849),
+a self-taught clockmaker and watchmaker with great interest in the
+sciences. A telescope that he produced about 1818 was considered to be
+the finest in the country at that time. His greatest achievement was a
+tall case astronomical clock that he devised and constructed; it was
+completed in 1790 and is considered to be the most complicated domestic
+clock on record.[36] Folger also produced quadrants and compasses, and
+made astronomical observations. His observations of the solar eclipse of
+September 17, 1811, were published in 1815 in _Memoirs of the Academy of
+Arts and Sciences_.
+
+Probably one of the most significant of the surviving early American
+scientific instruments is a pair of gunners' calipers made and used by
+PAUL REVERE (1735-1818) of Boston. The calipers are made of incised
+brass, measuring 7 inches in length and 1-3/4 inches in width. They are
+signed on the reverse side with the name "Revere" in the style of script
+signature used by this maker in many of his engravings. The design of
+the instrument is substantially different from that which is commonly
+found in English, French, and German gunners' calipers of the period,
+and was probably Revere's own. (See figs. 19, 20.)
+
+[Illustration: Figure 18.--Orrery by Joseph Pope completed in 1787 for
+Harvard University. Engraved plates and bronze figures were made by Paul
+Revere. The orrery is 6-1/2 ft. in diameter and 6-1/2 ft. high. The
+twelve figures at the corners are said to have been carved in wood by
+Simeon Skillin and cast in bronze by Paul Revere. Photo courtesy Harvard
+University.]
+
+It is believed that these calipers, which are preserved in the
+collection of the Bostonian Society in Boston, were probably used by
+Revere in 1775-1776. This was the period during which he was in charge
+of ordnance repairs for the Continental Army, and involved in various
+ventures for the manufacture of gunpowder and the casting of cannon.
+There is no evidence of other scientific instruments made by Revere,
+lending some weight to the belief that these calipers were made for his
+own use.
+

+inscribed signature. Photos courtesy the Bostonian Society, Boston,

+
+Other Massachusetts instrument makers include Gideon Fairman (1774-1827)
+of Newburyport who was a partner of William Hooker in the firm of Hooker
+& Fairman, which dealt in mathematical instruments before 1810.[37]
+Fairman later moved to Philadelphia, where he was associated with the
+engraving firm of Draper, Murray & Fairman.
+
+At the end of the 18th century Samuel Emery was making mathematical
+instruments in Salem, at the same time that John Jayne was engaged in
+the same work in that community.[38]
+
+John Potter of Brookfield, Massachusetts, produced surveying instruments
+in the last quarter of the 18th century. A graphometer signed with his
+name and dated 1785 is in the collection of the firm of W. & L. E.
+Gurley in Troy, New York.
+
+
+_Rhode Island_
+
+One of the earliest and most important of the instrument makers of Rhode
+Island was Benjamin King (1707-1786), of Newport. He was the son of
+Capt. Samuel King of Salem, Massachusetts, where he was born and
+baptized on March 13, 1707. He was a brother of Daniel King of Salem.
+Benjamin eventually moved to Newport, where he married Mary Hagger in
+July 1742. They had four children: Benjamin, Mehitable, Samuel, and
+Mary. He established himself as a respectable businessman in the
+community, and in 1759 or 1760 he became the senior partner in the
+importing and retailing firm of King & Hagger, "near the sign of Mr.
+Pitt," dealing in general merchandise, mathematical and nautical
+instruments, and stationery. William Hagger was probably the junior
+partner, and may have been King's brother-in-law. King began making his
+own instruments for sale, surviving examples dated as early as 1762. The
+partnership was dissolved early in the 1760's. In 1766 Benjamin King was
+importing, making, and selling quadrants and other instruments "At the
+Sign of the Mathematical Instruments" next to the Golden Eagle on Thames
+Street. His son Samuel King occupied the same premises, where he dealt
+in paints and artists supplies.
+
+When the British occupied Newport, King moved to North Kingstown, but he
+returned after the British vacated the city. He was 79 when he died in
+1786, and his son Samuel King succeeded him in business.[39]
+
+William Guyse Hagger (c. 1744-1830?), born in Newport, is believed to
+have been the son of William Hagar and Mary Knowlton. He was a quadrant
+maker (see fig. 21). In 1774 he headed a household that consisted of
+his wife, five children, and a colored servant. Whether it was he or his
+father who was the partner of Benjamin King cannot be determined with
+certainty. When Newport was occupied by the British, Hagger moved to
+Cranston, where he joined the Pawtuxet Rangers and served as a sentinel
+at Pawtuxet Fort in 1778. No members of the Hagger family appear in the
+1790 census of Newport, but a William Hager is reported as having died
+in Boston in 1830 at the age of 82. It seems likely from the age and
+dates that it was William Hagger the elder who worked as a partner in
+the firm of King & Hagger, which was established in 1759 or 1760.[40]
+
+[Illustration: Figure 21.--Davis quadrant or backstaff made and signed
+by William Guyse Hagger of Newport, Rhode Island, about 1760-1770. USNM

+
+Another instrument maker of Rhode Island was William Hamlin (1772-1869).
+He had established himself in Providence by the beginning of the 19th
+century in the manufacturing and repairing of mathematical and nautical
+instruments, for which there was an active market in that city. Hamlin
+was one of the first engravers in America and the first in Rhode Island.
+He designed and engraved banknotes for many banks in the State and for
+other institutions. At the same time he carried on a general trade in
+the sale of musical instruments. Hamlin moved his shop several times,
+but from 1847 until his death he worked at "The Sign of the Quadrant"
+(see fig. 22) at 131 South Water Street. He was equally interested in
+optics and astronomy, and it has been claimed that he constructed the
+first telescope in America. It is well established that he worked for
+many years to perfect a reflecting telescope for his own use.[41]
+
+Instruments were made also by Paul Pease, who may have been the husband
+of the daughter of Nathaniel Folger of Nantucket. This Elizabeth Folger
+Pease, wife of a Paul Pease, was born in 1720 and died in 1795. Little
+is known about Pease except for the name "Paul Pease 1750" inscribed on
+a quadrant in the collection of the Rhode Island Historical Society.[42]
+
+
+_Connecticut_
+
+The clockmakers who worked in Connecticut during the span of the 18th
+century numbered almost a hundred. Yet only a half dozen appear on
+record to have made or sold instruments in addition to clocks. Among
+these were several members of the Doolittle family, including Isaac
+Doolittle (1721-1800) of New Haven. In 1763 he advertised that he sold
+surveying compasses in addition to clocks, watches, bar iron, and
+chocolate.[43] His son Isaac Doolittle, Jr. (1759-1821), also of New
+Haven, established a shop of his own, which he advertised in 1781 as
+having
+
+ Compasses of all kinds, both for sea and land, surveyors scales,
+ and protractors, gauging rods, walking sticks, silver and plated
+ buttons, turned upon horn; also clocks and watches made and
+ repaired ...[44]
+
+Although not very active as a clockmaker, Isaac Jr. appears to have
+specialized more in the production of surveying and nautical
+instruments. He took over his father's business just before the latter's
+death, and in 1799 he advertised[45]:
+
+[Illustration: Figure 22.--Trade cards of William Hamlin (1772-1869),
+engraver and instrument maker of Providence, Rhode Island. In collection
+of Rhode Island Historical Society, Providence.]
+
+ The subscriber having commenced business at the shop lately
+ occupied by Mr. Isaac Doolittle, in Chapel Street, where he repairs
+ watches, makes and repairs Surveyors Compasses and Chains, Brass
+ Amplitude, plain brass and common Ship's Compasses, Gauging Rods,
+ Quadrants, repair'd &c. every favor gratefully received by the
+ public's humble servant, Isaac Doolittle, jun.
+
+Enos Doolittle (1751-1806), a nephew of Isaac Doolittle, Sr., made,
+sold, cleaned, and repaired clocks and surveying and marine compasses
+from 1772 through 1788 at his shop in Hartford. He also sold these items
+through agents in Saybrook and Middleton.[46]
+
+One of the best known of the Connecticut clockmakers was Peregrine White
+(1747-1834), of Woodstock. White was a descendant of the first Pilgrim
+child, and a native of Boston. After serving an apprenticeship, he
+worked as a clockmaker and silversmith in Boston. He was accused of
+forging silver spoons and left the city to settle in Woodstock. He
+established his own shop west of Muddy Brook Village.[47] In addition to
+fine tall-case clocks, for which he was noted, White also produced
+surveying compasses, one of which is in the collection of the U.S.
+National Museum (fig. 23). A similar specimen in Old Sturbridge Village
+is reputed to have been used for surveying the town of Southbridge,
+Mass.
+
+Benjamin Hanks (1755-1824), of Mansfield and Litchfield, inserted a
+notice in a newspaper in 1808 to notify the public that he and his son
+Truman Hanks, in partnership, had "surveyors compasses upon the
+Rittenhouse improved plan" in addition to such other commodities as
+brass cannon, bells from their own foundry, clocks, goldsmith's items,
+and stocking looms.[48]
+
+Ziba Blakslee (1768-1834), of Newton, worked as a clockmaker, goldsmith,
+and bell founder and he advertised that he made and sold surveying
+instruments.[49]
+
+In New Haven, Clark Sibley and Simeon Marble organized the firm of
+Sibley & Marble and advertised that in addition to repairing swords and
+cutlasses, clocks and watches, they also repaired mathematical and
+surgical instruments.[50]
+
+[Illustration: Figure 23.--Brass surveying compass made about 1790 by
+Peregrine White (1747-1834) of Woodstock, Connecticut. USNM 388993.]
+
+One of the instrument makers of New England who has remained relatively
+unknown was Benjamin Platt (1757-1833), who was born in Danbury,
+Connecticut, on January 3, 1757.[51] He married Adah Fairchild of the
+same city in 1776, and it is believed that he must have completed his
+apprenticeship by that date inasmuch as apprentices usually were not
+allowed to marry.
+
+It is not known how long Platt worked in his native city, but by 1780 he
+had moved to Litchfield, where he worked in gold, silver, and brass. He
+became established as a clockmaker and produced tall case clocks and
+other types. In 1787 he was in New Milford, a town adjacent to Danbury,
+where he produced surveying compasses (see fig. 24). Three years later,
+in 1790, he was at Milford, where he invented a "Compass for measuring
+distance in hilly country." In 1793 he returned to New Milford, where he
+made a clock to order for Eli Todd, and by 1800 he had moved to
+Lanesboro, Massachusetts.
+
+
+_Ohio_
+
+Benjamin Platt was the migratory type. In 1817 he migrated from
+Lanesboro to Columbus, Ohio. His son, Augustus Platt (1793-1886), also
+made mathematical instruments (see fig. 25) in Columbus. In 1809 a
+grandson, named William Augustus Platt was born. When the child's mother
+died, Benjamin and Adah Platt adopted the boy, and when he came of age
+he went into the watchmaking trade. William Platt married Fanny Hayes,
+sister of President Hayes.[52] His shop was listed in the 1843 city
+directory; it was the first jewelry and clock and watch store in the
+community.
+
+An interesting account of instrument making in Ohio is found in the
+report of a missionary, John Heckewelder. He mentioned the brothers
+Joseph and Francois Devacht who worked as watchmakers and instrument
+makers in Gallipolis, Ohio. Writing in 1792, Heckewelder stated that
+"the most interesting shops of the Workmen [in Gallipolis] were those of
+the Goldsmiths and Watchmakers. They showed us work on watches,
+compasses, sundials finer than I have ever beheld."

+Ohio State Museum.]
+
+
+_New York_
+
+There were relatively few makers of mathematical instruments in New York
+City before the end of the 18th century. Perhaps the earliest was John
+Bailey, who moved from Fredericksburg, Virginia, to Fishkill, New York,
+in 1778. He was a cutler by trade, and he made and sold surgical
+instruments.[53]
+
+"Bulmain & Dennies" at 59 Water Street in New York were the appointed
+agents to sell the "Perpetual Log or Distance Clock to find a ship's way
+at sea." The device had been patented in the United States, and one of
+the instruments was displayed at the bar of the Tontine Coffee House,
+according to an advertisement in the July 23, 1799, issue of the _New
+York Gazette and General Advertiser_.
+
+H. Caritat, at 153 Broadway in New York, imported and sold "The
+Planispherical Planetarium." This item was described in an
+advertisement[54] as "a graphic representation of the earth, in twelve
+particular positions during its revolutionary course around the sun, as
+also of the Moon's revolution around the earth, together with literal
+description of parts and motions, etc." The advertisement also stated
+that Caritat sold "Carey's newly improved Terrestrial and Celestial
+Globes which omitted the Constellary Configurations."
+
+[Illustration: Figure 25.--Surveying theodolite made by Augustus Platt
+(1793-1886) of Columbus, Ohio, in the early 19th century. Photo courtesy
+Ohio State Museum.]
+
+In 1785 M. Morris of New York City made and sold his own invention of a
+"Nautical Protractor for the price of One Dollar." In an advertisement
+in _The Independent Journal or the General Advertiser_ of May 25, 1785,
+he explained that the device was for use in the construction of globular
+maps and Mercator charts. He also made another protractor for attaching
+to the end of a ruler for measuring distances on charts. He planned to
+publish a treatise on the subject of his inventions.
+
+James Youle, a cutler and mechanician with a shop located first on Fly
+Street and then at 64 Water Street "at the Sign of the Cross-Knives and
+Gun," sold a large variety of cutlery and hardware for gun repair. He
+also made surgical instruments. He died in February 1786 at the age of
+46 as the result of an injury to his chest from a breaking grindstone
+while working in his shop. He was survived by a widow and nine children
+and was succeeded in business by his son John Youle.[55]
+
+
+_New Jersey_
+
+One of the few instrument makers known to have worked in New Jersey was
+Aaron Miller of "Elizabeth-town." He was first noted in the New York
+newspapers in 1748 when he notified the public that, in addition to
+clocks, he made compasses, chains for surveyors, and church bells, for
+which he maintained his own foundry. When he died in 1771 he left all
+his tools to a son-in-law, Isaac Brokaw.[56]
+
+Another craftsman who is entitled to being included as an instrument
+maker was Richard Wistar. When Casper Wistar died in 1752, his son
+Richard succeeded him as owner of the famous glass works. In addition to
+window glass and glassware, Richard Wistar also produced such special
+products as retorts for use in chemistry and "electerizing globes and
+tubes," as well as bottles for Leyden jars that Benjamin Franklin had
+urged him to attempt in the early 1750's.[57]
+
+
+_Delaware_
+
+George Crow (ca. 1725-1771/72) of Wilmington, Delaware, was apparently
+well established as a clockmaker in the community by the time of his
+marriage in 1746 to Mary Laudonet. They had four children, and Crow's
+two sons followed his trade. George Crow was active in civic affairs,
+and in addition to clocks, he produced surveying compasses, several of
+which have survived.[58]
+
+
+_Maryland and Virginia_
+
+Brief mention has already been made of the Chandlee family of
+clockmakers and instrument makers of the 18th century. The founder of
+the line and first of interest was Benjamin Chandlee, Sr., who migrated
+in 1702 from Ireland to Philadelphia, where he was apprenticed to Abel
+Cottey, clockmaker, and eventually married his daughter. His son
+Benjamin Chandlee, Jr. (1723-1791), worked as a clockmaker in
+Nottingham, Maryland, where he produced instruments as well as clocks. A
+fine example of a brass surveying compass--inscribed with his name, and
+which is believed to have been made for the Gilpin family in about
+1761--is on exhibition in the Chester County Historical Society. He had
+four sons, and a few years before his death he established the firm of
+Chandlee & Sons, the name of which was changed to Ellis Chandlee &
+Brothers a year before he died.
+
+The oldest of Benjamin Jr.'s four sons was Goldsmith Chandlee
+(c.1746-1821). After serving an apprenticeship with his father,
+Goldsmith moved to Virginia and worked near Stephensburg (now Stephens
+City). He eventually established himself at Winchester and built a brass
+foundry and a shop where he produced clocks, surveying compasses,
+sundials, apothecary and money scales, surgical instruments, compasses,
+telescopes, and other items in metal. Numerous examples of his clocks
+and instruments have survived. Their fine quality attests to the claim
+that he was one of the foremost craftsmen of the 18th century. Several
+of his surveying compasses exist in modern collections. An instrument
+(fig. 26) that he made about 1794 for a surveyor named Robert Lyle is in
+the writer's collection; an almost identical instrument that Chandlee
+made for Lawrence Augustine Washington, George Washington's nephew, is
+exhibited in the library at Mount Vernon, Virginia.
+
+[Illustration: Figure 26.--The label of Goldsmith Chandlee. In the
+collection of Ohio Historical Society, Ohio State Museum.]
+
+Ellis Chandlee (1755-1816) also was apprenticed to his father, and he
+worked with his brothers in the shop. He established the firm of Ellis
+Chandlee & Brothers, in 1790, shortly before his father's death. The
+firm was dissolved in 1797 when the youngest brother, John Chandlee,
+left the firm. Ellis continued in partnership with his other brother,
+Isaac Chandlee (1760-1813), until about 1804, producing clocks,
+surveying instruments, and other metal articles. Their products were
+signed "Ellis and Isaac Chandlee, Nottingham," or, in the case of a
+surveying compass in the collection of the Chester County Historical
+Society, "E. & I. Chandlee, Nottingham." Isaac Chandlee also produced
+clocks and instruments under his own name only, for there are a number
+of surviving clocks and surveying compasses signed in such manner (see
+fig. 28).[59]
+
+[Illustration: Figure 27.--Brass surveying compass with outkeeper made

+Lyle. Over-all length, 14-1/2 in.; diameter, 7 in. Instrument, in
+original wooden case, bears ink signature of Robert Lyle. In collection
+of the writer.]
+
+One of the most important craftsmen of Maryland was Frederick A. Heisely
+(1759-1839). A native of Lancaster, Pennsylvania, he served an
+apprenticeship there with John Hoff, the master clockmaker, from 1777 to
+1783. Heisely served in the Revolution. In 1783, presumably upon the
+completion of his apprenticeship, he married Catherine Hoff, the
+clockmaker's daughter. He moved to Frederick, Maryland, where he
+established his own clockmaking shop and where he specialized in making
+mathematical instruments. A tower clock made in Frederick is in the
+collection of the U.S. National Museum. Heisely returned to Lancaster to
+become Hoff's partner, and worked with him until 1802. He then moved his
+shop to Harrisburg and worked there until 1820. He moved once more, this
+time to Pittsburgh where he advertised himself as a "Clock, Watch and
+Instrument Maker," with a shop at No. 6 St. Clair Street.
+
+[Illustration: Figure 28.--Brass surveying compass made by Goldsmith
+Chandlee for Laurence Augustine Washington in about 1795. In the library
+at Mount Vernon. Photo courtesy the Mount Vernon Ladies Association of
+the Union.]
+
+George Heisely (1789-1880), Frederick's son, who was born at Frederick,
+Maryland, achieved note in his own right as a maker of clocks and
+instruments. He worked at Second and Walnut Streets in Harrisburg. He
+is credited with being the person who selected the melody of "To
+Anacreon in Heaven" for "The Star-Spangled Banner," while he was serving
+as a member of the Pennsylvania State Militia.[60]
+
+
+_Pennsylvania_
+
+A number of instrument makers worked in Philadelphia, which was one of
+the important shipping centers during the 18th century and consequently
+one of the important markets for nautical instruments.
+
+Probably the earliest Philadelphia instrument maker of record was Thomas
+Godfrey (1704-1749) who was born in Bristol Township. After serving an
+apprenticeship, Godfrey developed his own business as a glazier and
+plumber. He is stated to have done the major part of the glazing of the
+State House in 1732, as well as similar work on Christ Church. He also
+worked for Andrew Hamilton and for James Logan.
+
+Godfrey had a natural inclination and interest in science and
+mathematics, which may have been further encouraged by his friendship
+with Benjamin Franklin, who resided in the same house. Godfrey was also
+a fellow member of Franklin's Junto.
+
+In 1730 Godfrey invented an improved backstaff or Davis quadrant, and
+loaned the instrument to Joshua Fisher to be used in the latter's survey
+of Delaware Bay. It is claimed that the location of Cape Henlopen was
+established on Fisher's map (published in London in 1756) by means of
+Godfrey's instrument. James Logan became interested in the improved
+backstaff invented by Godfrey and at Logan's request, the instrument was
+taken on a voyage to the West Indies by a Captain Wright for the purpose
+of testing it.[61]
+
+At the same time Logan sent a description of the instrument to London to
+the Royal Astronomer, Edmund Halley. No acknowledgment was made, and in
+1734 Logan sent a second description to Sir Hans Sloane and to Peter
+Collison for forwarding to the Royal Society. The arrival of this
+description coincided with the submission of the description of a
+similar instrument to the Society by its vice president, James Hadley.
+The Royal Society decided in favor of both inventors, and Godfrey was

+
+Godfrey is often confused with his son, also named Thomas Godfrey
+(1736-1763), who worked as a watchmaker in Philadelphia, and
+subsequently became active in literary arts.
+
+Benjamin Condy (fl. 1756-1792, d. 1798) was an instrument maker with a
+shop on South Front Street in Philadelphia. As early as 1756 he worked
+for most of the merchant shippers of the port, supplying them with a
+considerable number of sand glasses that ranged from the quarter-minute
+to the two-hour varieties. Although he made his own mathematical
+instruments, it is likely that he imported the sand glasses. According
+to Customs House clearances of 1789, he had imported from London on the
+ship _Pigou_ "three cases of merchandise" valued at £160/17/6 with a
+duty of $32.19, which may have included sand glasses.[62]
+
+When Condy retired in 1792 he was succeeded in business by Thomas Biggs
+at the same address. Biggs had originally served an apprenticeship with
+Condy, and then fought for the American cause in the Revolution for five
+years. Following the termination of his military service he had engaged
+in instrument making in New York for eight years before returning to
+Philadelphia, his native city. Biggs prospered and his advertisements
+continued until early in 1795.
+
+Thomas Pryor made instruments in a shop on Chestnut Street in 1778, but
+he evidently retired from business in the 1790's because the city
+directory of 1795 listed him merely as "gentleman." He is reported to
+have been one of those who, from the State House Yard, witnessed the
+transit of Venus.[63]
+
+Among the early makers of mathematical instruments in Philadelphia
+was William Dean (?-1797), who is believed to have been working in that
+city as early as 1778. His name first appears in local directories in
+June 1792, where his shop address was listed as No. 43 South Front
+Street. Later he advertised that he made and sold "Surveying
+instruments--Telescopes, Sextants, Quadrants--and every article
+requisite for navigation, surveying, levelling, &c...."
+
+According to details which were noted in his last will, which was dated
+June 1, 1797, and filed and proved in the following month, Dean's death
+appears to have been preceded by a long illness. He designated his two
+sisters as his executrices, and the fact that his will specified the
+appointment of a Mr. Thomas Yardley, Jr., as guardian of his three
+children indicates that he may have been a widower at the time of his
+death.
+
+A surveying compass by this maker was recently brought to light in, the
+Clark County Historical Society, Springfield, Ohio, by Dr. Donald A.
+Hutzlar of the Ohio State Museum. The instrument is a plain compass in
+brass without levels, 13-1/2 inches in length, and with a 5-inch needle.
+The dial is marked "DEAN PHILAD^a." The wooden cover for the instrument
+is marked with the names of previous owners and dates, as follows:
+
+ Jno. C. Symes, Aug. 10, 1778
+ I. Ludlow, 1791
+ Henry Donnel, July 24, 1794
+ Jonathan Donnel, 1796
+ John Dyherty
+ Thomas J. Kizer, 1838
+ David J. Kizer, '78.
+
+A description of this instrument in "_The History of Clark County,
+Ohio_" by A. P. Steele, published in 1881 by the W. H. Beers Co. of
+Chicago, adds considerably to its interest as a historical record of
+American scientific instruments and their use: "Col. Thomas Kizer, the
+veteran surveyor, has in his possession a compass made by Dean of
+Philadelphia; this instrument was owned and used by his father, David
+Kizer, who obtained it from John Dougherty about 1813; Dougherty got it
+from Jonathan Donnel. This relic is marked I. Ludlow, 1791; Henry
+Donnel, 1794; J. Donnel, 1796, John Dougherty, 1799; these marks are
+rudely scratched upon the cover of the instrument, and bear every
+evidence of being genuine; there is no doubt but that this old compass
+was used in making the first surveys in this county, or that it is the
+identical instrument used by John Dougherty, in laying off Demint's
+first plat of Springfield, and by Jonathan Donnel on the survey of 'New
+Boston.'" It is to be noted that some discrepancies exist in the listing
+of names and dates of the previous owners between Steele's _History_ and
+those which actually appear on the cover of the instrument. Steele
+apparently made the changes he deemed necessary in his account of the
+instrument.
+
+Between 1791 and 1795 the same address was also occupied by a cooper
+named Michael Davenport, and from 1797 to 1801 by "the Widow Davenport,"
+presumably widow of Michael. From 1802 to 1804 the same address is
+listed for William Davenport, "Mathematical Instrument Maker,"
+apprentice to William Dean, and believed to be the son of Michael.
+During the next ten years Davenport's address was 45 South Front Street,
+and then, to 1820, was 25 South Front Street.[64] Several brass
+surveying compasses bearing his name have survived.
+
+Another maker of mathematical instruments about whom nothing further is
+known is Charles Taws, who was listed in this manner in the Philadelphia
+directory of 1795.
+
+[Illustration: Figure 30.--Brass surveying compass marked "F. Heisely
+Fred:*town." In collection of Ohio Historical Society, Ohio State
+Museum.]
+
+The making of instruments in glass appears to have been a specialized
+business in the Colonies, because those who worked in this field do not
+appear to have produced instruments in other materials. One of these
+makers of glass instruments--specifically barometers, thermometers and
+"Glass Bubbles to prove spirits, of different kinds"--was Alloysius
+Ketterer. He maintained a shop in the house of a Charles Kugler at "the
+sign of the Seven Stars," corner of Race and Fourth Streets in
+Philadelphia, in 1789. He moved to another address in Race Street in
+1790 and was eventually succeeded in business by Martin Fisher, who
+increased the number of types of glass instruments made and sold at the
+shop.[65]
+
+Henry Voight (1738-1814) was a man with a varied career. Of German
+ancestry, he was trained as a clock-and watchmaker, and he was a skilled
+mechanic. He operated a wire mill in Reading, Pennsylvania, in 1780 and
+moved shortly thereafter to Philadelphia, where he established a
+clockmaker's shop on Second Street. He became a close friend of the
+inventor John Fitch in about 1786, and in the following year he became a
+shareholder in Fitch's company for producing steamboats. In 1792 he
+entered into a short-lived partnership with Fitch to manufacture steam
+engines. In 1793 he invented a process for making steel from bar iron.
+In the same year President Washington appointed Voight to the position
+of chief coiner of the Philadelphia Mint, and he continued in that
+position until his death in 1814. He was closely associated with David
+Rittenhouse, Andrew Ellicott, Edward Duffield, and others.
+
+Although there is no record of Voight's career as an instrument maker,
+there is nevertheless some evidence that he worked in that field. In the
+collection of the U.S. National Museum there is a brass equal-altitude
+telescope (fig. 31) made about 1790, that is signed "Henry Voigt." His
+name was spelled "Voigt" and "Voight" interchangeably.
+
+Henry's son Thomas Voight worked as a clockmaker on North Seventh Street
+in Philadelphia around 1811. He was the maker of a tall case clock,
+ordered by Thomas Jefferson, that Jefferson's daughter presented in 1826
+to her father's physician, Dr. Dunglison, for settlement of medical
+services.[66]
+
+There were several instrument makers in provincial Pennsylvania, but the
+majority of such craftsmen worked in Philadelphia. Dr. Christopher Witt
+(1675-1765), an emigrant from England, worked in Germantown from about
+1710 to 1765. He was well known locally as a medical doctor, scientist,
+"hexmeister", clockmaker, and teacher. It is traditionally claimed that
+he produced mathematical instruments in addition to timepieces. He
+described the great comet of 1743 and built his own 8-foot telescope.
+One of his apprentices may have been Christopher Sower (1693-1740), of
+Germantown and Philadelphia, who achieved renown as a doctor, farmer,
+author, printer, papermaker, and clockmaker. He also produced
+mathematical instruments.[67]
+
+George Wall, Jr., of Bucks County, was the author of a pamphlet on the
+subject of "a newly invented Surveying Instrument, called the
+Trigonometer." The instrument was described and illustrated in the
+pamphlet, which was published in Philadelphia in 1788. Washington's own
+copy, bearing the inscription "To the President of the United States
+from the Author" is in the collection of the Boston Athenaeum.
+
+George Ford of Lancaster maintained a shop on West King Street, probably
+from the end of the 18th century until 1840. There he made tall case and
+other clocks, surveying compasses, and other instruments for the retail
+trade. However, he "did not push the business of Watchmaking and
+Clockmaking so hard, for the manufacture of nautical instruments and
+surveyors instruments was a more important part of his business."[68]
+Upon his death in 1842 he was succeeded by his son George Ford II.
+
+Thomas Mendenhall repaired clocks and mathematical instruments in a shop
+on King and Queen Streets in the borough of Lancaster in 1775.[69]
+
+John Wood of Philadelphia was a wholesale supplier of parts for
+clockmakers and watchmakers. According to a notice in the May 7, 1790,
+issue of _Pennsylvania Packet_, he had "pocket compasses, steel magnets,
+Surveying compass needles, surveyors chains, etc." Since no mention was
+made of making or mending instruments, it is probable that Wood was
+merely importer and wholesaler.
+
+Another instrument maker of Philadelphia about whom little is known is
+Bryan Gilmur, who worked at the close of the 18th century making
+instruments and, possibly, clocks.[70]
+
+James Jacks (also listed as James Jack) first worked as clockmaker and
+watchmaker in Charleston, South Carolina, in the 1780's; he later moved
+to Philadelphia where he maintained a shop on Market Street where he
+sold a variety of instruments. In the June 5, 1797, issue of _The
+Federal Gazette_ he announced that, in addition to jewelry, clocks and
+watches, he "also had for sale mathematical instruments in cases very
+compleat; Surveyors Compasses and Theodolites; ship's Quadrants; Fishing
+Rods and Reels; Billiard Balls and sheet ivory; silver and plated coach,
+chaise and chair Whips."

+
+_Instruments of Wood_
+
+
+The Use of Wood
+
+An interesting fact concerning the instruments produced by 18th-century
+craftsmen is the relatively high incidence of instruments constructed of
+wood instead of brass or other metals. A significant reference to this
+use of wood is found in Alexander Hamilton's "Report on the Subject of
+Manufactures," published in 1821,[71] which refers to such items of wood
+as "Ships, cabinet-wares and turnery, wool and cotton cards, and other
+machinery for manufactures and husbandry, mathematical instruments," ...
+and "coopers' wares of every kind."
+
+Most common of these mathematical instruments is the surveying compass,
+possibly the instrument most needed and produced in America. Recorded in
+public and private collections are 31 known examples of such compasses
+made of wood, a rather large number. Furthermore, a substantial number
+of these were being produced simultaneously by skilled craftsmen who at
+the same time were making similar instruments in brass.
+
+Finally, from a study of the surviving examples of wooden surveying
+compasses comes the interesting and perhaps significant fact that all
+the known makers were from New England. The towns and cities in which
+they worked were Boston and Plymouth in Massachusetts, Windsor and New
+Milford in Connecticut, and Walpole and Portsmouth in New Hampshire. A
+careful study of the advertisements and works of the instrument makers
+in the other large cities of the Colonies, such as New York, Baltimore,
+and Philadelphia, reveals no examples of wooden scientific instruments.
+Excluded, of course, are those instruments normally made of wood, such
+as the octant and the mariners quadrant.
+
+Two possible exceptions are instrument makers of New York City. The
+first is James Ham, a maker of mathematical instruments "at the house
+wherein the Widow Ratsey lately lived near the Old Dutch Church on
+Smith Street" who advertised in the May 27, 1754, issue of _The New York
+Mercury_ that he made and sold
+
+ mathematical instruments in wood, brass, or ivory, theodolites,
+ circumferentors, sectors, parallel rules, protractors, plain
+ scales, and dividers, the late instrument called an Octant, Davis'
+ quadrants, gauging rods, sliding and gunter's scales, amplitude
+ wood box and hanging and pocket compasses, surveying chains,
+ japanned telescopes, dice and dice boxes, mariners compasses and
+ kalenders, etc.[72]
+
+Ham subsequently moved his business to Philadelphia where he first
+advertised in 1764, stating that he worked at the sign of "Hadley's
+Quadrant" at Front and Water Streets in Philadelphia and sold all forms
+of instruments in silver, brass, and ivory as well as "large brass
+pocket dials, fitted to the latitude of Philadelphia." In 1780 his son
+James Ham, Jr., advertised from the same address as a maker of
+mathematical instruments, specializing in "Hadley and Davis
+Quadrants."[73]
+
+The second exception is William Hinton, who advertised in _The New York
+Gazette and the Weekly Mercury_ of May 4, 1772, as follows:
+
+ WILLIAM HINTON, Mathematical Instrument Maker, at Hadley's
+ Quadrant, facing the East Side of the New Coffee House, Makes and
+ sells all sorts of Mathematical Instruments, in Silver, Brass,
+ Ivory or Wood, viz. Hadley's Quadrants, Davis's do. Crostaf's
+ Nocturnals, Gunters Scales, Plotting do. Cases of Instruments,
+ Surveyors Chains, Dividers with and without Points, Protractors,
+ paralelled Rulers, Rods for Guaging, Amplitude, hanging and common
+ Wood Compasses, Pocket do. three Foot Telescopes, Pocket do.
+ Backgammon Tables, Dice and Dice Boxes, Billiard Balls and Tacks,
+ Violin Bows and Bridges; with a Variety of other Articles too
+ tedious to mention: And as he is a young Beginner, he flatters
+ himself, he shall meet with Encouragement; and all those who please
+ to favour him with their Custom, may depend upon having their Work
+ done in the neatest and best Manner, and at reasonable Rates.
+
+It is mentioned that both Ham and Hinton worked in wood in addition to
+other materials, but it appears very likely that the use of wood
+referred specifically to those instruments normally made of wood, such
+as quadrants and octants, and not to other instruments.
+
+Any attempt to relate the making of wooden scientific instruments with
+the production of wooden clocks in New England has no conclusive result,
+yet there appears to be some relationship between the two. Wooden
+clocks were made as early as the 17th century in Germany and Holland,
+and they were known in England in the early 18th century. In the
+Colonies the wooden clock was first produced in Connecticut, and the
+earliest type was associated with Hartford County. This form was quite
+common in East Hartford in 1761, and its first production may have had
+some association with Ebenezer Parmele (1690-1777), since an association
+between Parmele and all of the earliest makers of wooden clocks can be
+traced.[74] Little is known about Parmele. His father was a cabinetmaker
+in Guilford, Connecticut, and Ebenezer practiced the same craft, in
+addition to being a boat builder. He was a man of means, held various
+town offices, and served as town treasurer. For a while he operated a
+cargo sloop on Long Island Sound. In 1726 he built the first tower clock
+in Connecticut for the Guilford meeting house. He was a versatile worker
+in wood, and it is believed that he served an apprenticeship in New York
+City with a Dutch clockmaker from 1705 to 1710, where he may have
+learned to make wooden clocks.
+
+This early type of wooden clock is associated with Benjamin Cheney
+(1725-1815), a clockmaker of East Hartford. The early or "Cheney" type
+of wooden clock was produced in Connecticut as late as 1812. A later
+form of the wooden movement began to appear about 1790, and was probably
+introduced by Gideon Roberts (1749-1813) of Bristol. Roberts had lived
+in the Wyoming Valley of Pennsylvania before 1790, and it is conjectured
+that he became familiar with the wooden clocks produced by the German
+settlers of that region.[75]
+
+It is not surprising that the wooden clock had its colonial origins in
+Connecticut, so completely was it adaptable to the pioneer conditions in
+that colony. The materials were the abundant native woods-cherry, apple,
+oak, and laurel. The parts were made with simple carpenter tools and a
+wooden foot lathe, using the methods of the cabinetmaker. Although it
+has been suggested that some relationship may have existed between the
+makers of wooden instruments in England, and the makers of wooden clocks
+and scientific instruments in the New England Colonies,[76] a careful
+study has failed to reveal any connection, and there appears to be
+little if any parallel between the two groups. Basically, the use of
+wood for making some mathematical instruments in New England resulted
+from the native familiarity with this material, which was also employed
+to a considerable degree for the construction of domestic and
+agricultural implements, and from the fact that many of the early
+clockmakers had been trained as or by cabinet makers, carpenters, and
+even dish turners. Random examples of a few of the more prominent
+clockmakers are Joseph Hopkins, a wood turner; Chauncey Jerome, who had
+been apprenticed to a wood turner; and Silas Hoadley, who had worked
+with a cabinet maker.
+
+Perhaps a basis for the prevalence of wood in these trades is to be
+found in the lines from a familiar poem:
+
+ The Yankee boy, before he's sent to school,
+ Knows well the mystery of that magic tool,
+ The Pocket knife.[77]
+
+But, from the technical point of view, it should be noted that those
+craftsmen who produced clocks and instruments and did not have their own
+brass foundries probably found that a good piece of straight-grained
+hardwood was as stable for holding its dimensions with the grain as a
+piece of brass. Shrinkage was at right angles to the grain; hence, for
+fixed linear stability wood was as good as brass. For rigidity per unit
+weight, wood was better than brass; and for availability and ease of
+working, wood was superior to brass.
+
+It has often been ventured that wooden clocks were first produced in
+Connecticut, because of the scarcity of brass for this purpose during
+the years between the beginning of the Revolution to the end of the War
+of 1812. The claim is made that brass was not being produced in the
+Colonies and that it was imported exclusively from England during this
+period. Certainly, the wholesale price index of metal and metal products
+shows a steady increase during this period, and a considerable jump
+during the period of the War of 1812, making brass an extremely
+expensive material. This may explain why the makers of clocks and
+instruments who made and sold brass clocks and instruments were
+producing the same products at the same time in wood which, as we have
+seen, was both plentiful and a satisfactory substitute.
+
+It can be surmised, therefore, that surveying instruments, as well as
+instruments for other purposes, were produced in both brass and wood
+simultaneously by many of the New England makers in order to provide
+suitable instruments in a flexible price range to meet the demands of
+the trade. Whereas today modern manufacturing methods make it possible
+to produce instruments in a wide variety, both in quality and price, to
+suit the needs and capabilities of every prospective purchaser, the
+production facilities of the 18th century were much more limited. The
+constant factor of skilled hand labor was costly. Metal was expensive.
+As evidenced in the records of Daniel Burnap, for instance, it was
+possible to produce surveying compasses in brass in two grades,
+presumably one more elaborate than the other. Yet Burnap's prices ranged
+between six pounds and four pounds for the metal instruments, making
+them still well out of reach of many of the would-be surveyors.
+Accordingly, Burnap--and presumably numerous other instrument makers of
+the period--produced from wood an economy model that sold for not more
+than two pounds, thus placing the item within the reach of the
+nonprofessional surveyor.
+
+This theory is supported amply by the discovery that several of the
+instrument makers who worked in brass also made instruments of wood
+during the same periods. In addition to the evidence in the records of
+Daniel Burnap, there are the surviving surveying instruments in brass
+and wood made by Samuel Thaxter, Thomas Greenough, and John Dupee,
+leaving little if any doubt that the reason for producing surveying
+compasses and similar items of wood during the 18th century was to
+satisfy the need for reasonably accurate yet inexpensive instruments.
+
+
+Surviving Instruments
+
+The fact that the surviving examples of the wooden instruments were
+produced only in New England seems to indicate merely that the New
+England instrument makers were more familiar with the use of wood as a
+material, and had greater facility in working with it.
+
+Undoubtedly other instruments produced by the 18th-century American
+makers have survived in addition to those already found. Quite likely
+examples of these wooden instruments still remain hidden in unexplored
+attics and other repositories. Yet, if the few thus far discovered is
+any criterion, the number ultimately recoverable will probably be but a
+fraction of the great number produced by the 18th-century makers during
+the half century or more in which they worked. Even allowing for those
+probably destroyed in the natural course of events, one cannot help but
+wonder what has happened to the remainder.

+in. long, 4-5/8 in. wide, and 7/16 in. thick. In collection of Dartmouth
+College Museum.]
+
+A list of the surviving wooden instruments is given in the Appendix (p.
+153). Many of these wooden instruments bear signatures or other marks
+that permit identification of their makers, but a number of specimens
+have been found that are not signed. In most instances they show
+evidence of professional workmanship, and they may have been the work of
+known craftsmen. One or two examples are obviously homemade by unskilled
+amateur practitioners.
+
+[Illustration: Figure 33.--Wooden surveying instrument, maker not known.

+metal punches and the letter "N" to designate the north point. The
+instrument is 12 in. long; diameter is 8 in. In collection of Dartmouth
+College Museum.]
+
+Several unsigned wooden instruments of professional quality are in the
+collection of the Dartmouth College Museum. Of particular interest is a
+semicircumferentor (fig. 32) that belonged to the Reverend Eleazar
+Wheelock (1711-1779) who founded Moor's Indian Charity School at
+Lebanon, Connecticut, which subsequently developed into Dartmouth
+College. It is claimed that it was with this instrument that the area of
+the college was surveyed when it moved to Hanover, N.H. The instrument
+is actually a graphometer consisting of a block of hard wood faced with
+a brass plate with a trough compass; it is tentatively dated about 1769.
+The identity of the maker is unknown, but it may have been the product
+of Hagger, who made a similar instrument, illustrated here, or it may
+have been produced by any one of the other makers noted. The type of
+instrument is an old one. It is described in John Love's _Geodaesia, Or
+the Art of Surveying and Measuring Land_, published in London in 1688.
+Abel Flint[78] also commented on this semicircle as being sometime used,
+as well as the plane table and perambulator--
+
+ ... but of these instruments very little [use] is made in New
+ England; and they are not often to be met with. For general
+ practice none will be found more useful than a common chain and a
+ compass upon Rittenhouse's construction.
+
+Another of the unusual wooden surveying instruments in the collection of
+the Dartmouth College Museum is a wooden surveying compass (fig. 33) in
+which the sighting bars appear relatively close to the dial. A metal
+plate, painted green, is stamped with the degrees marked to 90°. A
+single N for the north point is stamped into it, presumably with steel
+punches. The instrument is relatively primitive, and is sufficiently
+different from the other examples noted to merit mention. There is no
+maker's name, nor any clue to the date or place or period of origin.
+
+An unsigned semicircumferentor made of wood is owned by Mr. Roleigh Lee
+Stubbs of Charleston, West Virginia. The instrument measures 3-3/4 in.
+by 7-1/2 in. by 1 in., and there are sighting bars 3 in. high on a
+swinging brass bar pinned at the center of the base. It has a trough
+compass, and the gradations around the edge of the semicircle are marked
+with tiny brass pins. The date "1784" is stamped into the wood with the
+same type of figures as appear in the degree markings, probably with
+small steel punches.
+
+A surveying compass of the conventional type, also made of wood, is in
+The Farmer's Museum at Cooperstown, New York. The wood is ash or oak,
+12-3/4 in. long and 6-1/2 in. in diameter, with the sighting bars 5 in.
+high. The compass card consists of cut-out printed letters pasted upon a
+printed compass rose, and the fleur-de-lis at North is inked-in by hand.
+This may be a homemade replacement of the original card. The instrument
+is believed to date between 1760-1775.
+
+[Illustration: Figure 34.--18th-century semicircumferentor. Inscribed
+brass plate is mounted on a mahogany block; brass sighting bars are
+mounted on a swivelling bar. The trough compass is on a silvered dial.
+In collection of the writer.]
+
+Of equal interest is a large semicircumferentor made by an unknown
+American instrument maker in the second half of the 18th century. The
+instrument (fig. 34) consists of a plate of hammered brass attached to a
+quarter circle block of mahogany, with a glass covered trough compass
+within a silvered opening, and the gradations stamped into the brass.
+The brass sighting bars are attached to a swivelling bar that can be
+fixed in place with a set screw underneath the block. The instrument,
+which is in the collection of the writer, is not signed with a maker's
+name. Its workmanship is excellent, and professional.
+
+On the basis of a comparison of these instruments with those produced by
+known professional makers, it becomes apparent that all of them were
+made professionally. The possibility that some of these wooden surveying
+compasses may have been produced by the farmer or local surveyor for his
+own use is extremely unlikely. Homemade instruments such as those
+described below were unquestionably the exception instead of the
+rule.
+
+[Illustration: Figure 35.--Homemade wooden surveying compass carved from
+block of maple entirely with a jackknife; painted in red. In collection
+of Preston R. Bassett, Ridgefield, Connecticut.]
+
+An exception to this generalization, and an extremely fine example of
+the whittler's art, is a surveying compass (fig. 35) in the collection
+of Mr. Preston R. Bassett of Ridgefield, Connecticut. This is a
+comparatively small instrument made of maple; the body was painted red.
+It is carved entirely by means of a jackknife, and the sighting bars are
+also whittled to shape and mortised permanently into the frame. A lid
+covering the dial is carved from soft pine. The compass dial is
+handdrawn in black ink, and the North point is painted in the form of a
+decorative fleur-de-lis in red and green. A homemade ring of pewter
+surrounds the compass rose at needle level. This is graduated in
+degrees, with every 10° marked, stamped with steel punches. The ring is
+set into the base by means of wooden pegs. The steel needle is nicely
+cut, and it is probably the only part purchased by the maker.
+
+This is unquestionably a homemade instrument produced by a skillful
+whittler early in the 18th century.
+
+
+Compass Cards
+
+A fact that becomes apparent in a comparison of the surviving examples
+of wooden surveying compasses made in New England is the similarity of
+the compass cards used by makers in the seaport cities (see fig. 36).
+The compass card in each of these instances is the type designed for a
+mariner's compass, bearing a star of 32 rays to mark the 32 points of
+the heavens. The North point is designated with an elaborate
+fleur-de-lis, and the East is emphasized with scrollwork. These are
+features which were not designed primarily for land surveying.
+Presumably, these makers had a quantity of engraved or printed compass
+cards that they used in both marine and land surveying compasses. This
+is true in the case of the compasses made by James and Joseph Halsy,
+Greenough, Clough, Warren, Thaxter, Dupee, Breed, and Bowles. On the
+other hand, the dial of Huntington's compass was painted directly on the
+wood, and the semicircumferentors do not utilize the marine compass
+card. Obviously these makers resorted to this practice for reasons of
+economy--to reduce costs of engraving and printing, and using the same
+card for both types of instruments that they produced.
+
+
+Trade Signs
+
+An interesting sidelight in the study of the makers of scientific
+instruments is the advertising they used, particularly the design of
+their signboards. The most popular symbol appears to have been the
+quadrant, as the phrase "At the Sign of the Quadrant" is found
+repeatedly in advertising in several of the seaport cities of the 18th
+century.
+
+[Illustration: Figure 36.--Unsigned wooden surveying compass, with an
+interesting example of a mariner's compass card.]
+
+In Providence, William Hamlin used the designation in the first part of
+the 19th century, while Philadelphian John Gould featured the sign at
+the end of the 18th century. During an even earlier period, William
+Hinton designated his address to be "At Hadley's Quadrant" in New York
+City. Both Gould and Hinton were English, which may have had some
+bearing on their selection of the quadrant as a symbol of their
+merchandise.
+
+Other signboards were as colorful, such as Jonathan Dakin's "Sign of the
+Hand and Beam," James Youle's "Sign of the Cross-Knives and Gun," and
+Charles Kugler's house in Philadelphia with its "Sign of the Seven
+Stars" (that is, Great Bear), which housed the shops of several
+instrument makers.
+
+The two most interesting and significant of the instrument makers' trade
+signs were those advertising the shop of Samuel Thaxter. The first of
+these was the carved wooden figure of "The Little Admiral," which was a
+favorite landmark at No. 1 Long Wharf in Boston for almost a century and
+a half. It was the handiwork of John Skillin, the 18th-century
+woodcarver of Boston, upon whose death on January 24, 1800, the
+_Chronicle_ commented that "he was for many years the most eminent of
+his profession." John Skillin and his brother Simeon worked in Boston
+from about 1777 and produced most of the figureheads that issued from
+that port during that period, as well as a number of other notable
+ornamental wooden figures.
+
+[Illustration: Figure 37.--"The Little Admiral," trade sign used for
+almost a century and a half in Boston, first by William Williams and
+later by Samuel Thaxter. Reputed to have been carved by John Skillin of
+Boston. In collection of the Bostonian Society.]
+
+According to Mrs. H. Ropes Cabot of the Bostonian Society, the figure of
+"The Little Admiral" (fig. 37) had been carved for William Williams, who
+brought it with him to Boston from Marblehead in 1770 when he
+established his shop. The figure was installed in front of the Crown
+Coffee House, and Williams's shop was thereafter designated by this
+symbol. The trade sign survived through the years of the Revolutionary
+War. When the original building of the Coffee House was burned, the
+carving was saved and installed on the new building erected in its
+place. In an account of Boston landmarks, Porter[79] related the figure
+to the Admiral Vernon Tavern at the eastern corner of Merchants Row. He
+was proved to have been in error, however, since the trade sign of that
+public-house was a portrait bust of Admiral Vernon and the place was
+known as the Vernon Head Tavern for half a century, even after the end
+of the Revolution.
+
+When Samuel Thaxter purchased the business from Williams's estate he
+acquired the figure as well, and he moved it to each new location for
+his shop. The figure of "The Little Admiral" continued to designate the
+firm even after Thaxter's death, until the firm finally went out of
+existence at the beginning of the 20th century. When the old store was
+torn down in 1901, the figure was preserved, presumably by the last
+owner's family. In 1916 it was acquired for the Bostonian Society by
+several of its members, and the figure has been preserved in the
+Society's Council Chamber since that time.
+
+The other interesting trade sign utilized by Samuel Thaxter is a carved
+figure of Father Time that is credited to John Skillin (see fig. 38).
+The figure is believed to have been commissioned by Thaxter during the
+last decade of the 18th century and installed by him in the interior of
+his shop. It is an important example of the American woodcarver's art,
+and is equivalent to the best work of the Skillin brothers.
+

+Thaxter in his shop in 18th and 19th centuries. Made of wood, it was

+
+
+The Makers
+
+Surprisingly, the names of the craftsmen who produced wooden instruments
+are not noted among the instrument makers. With only one or two
+exceptions, their names are hitherto unknown in the history of American
+science, and for that reason it has been considered advisable to present
+all available information that could be accumulated about them.
+
+
+_Joseph Halsy_
+
+The earliest known maker of wooden scientific instruments of Boston was
+Joseph Halsy. He appears to have been one of the sons of the James
+Halsie I, who was mentioned in a land deed of 1674 as a mathematician.[80]
+The land records indicate that James I was the father of several
+children, including Rebecca, a spinster; John Halsey, a mariner who died
+before 1716; Sarah, who later became Mrs. Dorsan; another daughter, name
+unknown, who became the wife of a Joseph Gilbert and the mother of two
+daughters and a son who inherited her share of her father's estate;
+Nathaniel Halsie; and probably Joseph Halsy. James Halsie I appears to
+have owned property consisting of land, a wooden house, and wharves on
+the North End, on North Street between Sun Court and Fleet Street.[81]
+
+The date of birth of Joseph Halsy of Boston has not been found, but
+mention is made of the fact that on January 29, 1697, he was married to
+Elizabeth Eldridge, the daughter of a mariner named Joseph Eldridge, and
+that five children resulted from the marriage, three sons and two
+daughters.[82] One son, Joseph, died in infancy and a daughter,
+Elizabeth, died at an early age.
+
+On February 26, 1704/5 Halsy purchased from Rebecca Halsey, the spinster
+daughter of James, her share in the house and land of her late father on
+North Street between Sun Court and Fleet Street.
+
+On April 19, 1714, Halsy and his wife deeded a house and land on North
+End, at the corner of Hanover and Salutation Streets, to a shipwright
+named Joseph Hood. Two years later, on March 2, 1716, he purchased from
+Jane, his sister-in-law, who was the widow of the mariner John Halsy,
+her share of the house and land of James Halsie, being the same property
+on North Street. On March 27 of the same year he purchased the share in
+the same property belonging to Sarah Dorsan, his widowed sister. In
+August 1719 he was forced to mortgage some of the property to a merchant
+named John Frizell, but the mortgage was cancelled in 1741.
+
+Halsy was married for a second time on January 10, 1731, to Mrs. Anna
+Lloyd, a widow.[83]
+
+[Illustration: Figure 39.--Wooden surveying compass "Made and sold by
+Joseph Halsy, Boston, New England." The instrument, made of maple, is 11
+in. long and has a diameter of 5-3/4 in. In the collection of New
+Hampshire Historical Society, Concord.]
+
+During the 1730's, Halsy continued to buy out the heirs of James Halsie.
+On March 6, 1730, he acquired the share of Mary Gilbert, a
+granddaughter, and on the same date he purchased from the James Halsey
+heirs their inheritance "part to land, wharf, house, shop and buildings
+on North Street." Other heirs remained, for in June 9, 1732, he bought
+out the share of Marty Partridge, another granddaughter, and on June 27
+the share of Joseph Gilbert, Jr., a grandson. In October 1740 he was
+forced to mortgage as security to James Bowdoin a house and land on the
+southwest side of North Street, but this was cancelled when on August
+26, 1751, Joseph Halsey and his wife, Anna, deeded to James Noble the
+land, wooden house, and wharves near Fish Street on North Street between
+Sun Court and Fleet Street, which apparently was formerly the property
+of James Halsey that Joseph had acquired with so much trouble over a
+period of 40 years.[84]
+
+The following advertisement relating to instruments sold by Halsy
+appeared in the issues of _The Boston Gazette_ for the months of
+September and October 1738:
+
+ Made and sold by Joseph Halsey jun. Hadley's New Invented Quadrant
+ or Octant the best and exacted Instrument for taking the Latitude
+ or Other Altitudes at Sea, as ever yet Invented.[85]
+
+The last dated record relating to Joseph Halsy which has been found is a
+letter dated February 3, 1762, that he wrote to Robert Treat Paine
+concerning legal matters.
+
+Only one complete instrument produced by Joseph Halsy appears to have
+survived--an especially fine wooden surveyors compass (fig. 39) in the
+collection of the New Hampshire Historical Society. It is made of maple.
+The compass card, probably the most interesting of any found in the
+wooden instruments, is hand-colored in black, blue, red, and gold. A
+fleur-de-lis marks the North point, and triangular pointers indicate the
+other compass directions. Inside the pointers are crudely painted female
+figures representing the seven arts: NW, Grammar; W, Logick; SW,
+Geometry; S, Arithmetick; SE, Astronomy; E, Rhetorick; and NE, Musick.
+Within a medallion at the center of the compass card is depicted a
+sailing vessel at sea; surrounding the medallion is a riband inscribed
+"Made and Sold by JOSEPH HALSY Boston--New England."[86]
+
+Another, but much less elaborate, compass card used by Joseph Halsy, is
+an engraved example (fig. 40) found glued in Thomas Paine's own
+manuscript copy of Charles Morton's _Compendium Physicae_, which is
+preserved in the collection of the Massachusetts Historical Society.
+
+John Halsy (fl. 1700-1750), also a mathematical instrument maker, had a
+shop on Green Street, in Boston, according to the Record Commissioner's
+"Report of the City of Boston." He was married on December 10, 1700, by
+the Reverend Cotton Mather. He probably was a brother of Joseph Halsy
+who worked in the same period.
+
+John Halsy subsequently abandoned his instrument-making business to
+become a pirate. He went out to Madagascar, where it is reported that he
+died in his own bed. He was buried with the rites of the Church of
+England in his own watermelon patch.
+

+
+
+_James Halsy II_
+
+James Halsy II (1695-1767), a mathematical instrument maker, was born in
+Boston on April 10, 1695, the son of Nathaniel and Hannah (Gross)
+Halsie. The parents had been married by the Reverend Cotton Mather in
+June 1693.[87] In 1716 young James Halsy was a member of the Artillery
+Company, and by 1720 he had the rating of 4th sergeant. He held town
+offices and was one of the founders of the New Brick Church of Boston.
+On May 30, 1717, he married Anna Gutridge (Goodrich). Ten years later,
+on September 22, 1727, he bought a house and land on North Bennett and
+Tileston Streets from Hugh Hall, a merchant; at the same time he deeded
+to Hall some land and a house adjacent to the latter on the southwest
+side of Green Street. On January 5, 1837, he deeded to his aunt(?), a
+single woman named Huldah Gross, a house and land on Ann Street that he
+had inherited from Thomas Gross, his grandfather. Several more real
+estate negotiations were recorded in the course of the next few years.
+In October 1740 he purchased a house and land on the north side of North
+Bennet Street from John Endicott; in January 1741 land on the east side
+of North Bennett Street; and in November 1748 half of the house and land
+of Edward Pell, adjacent to Huldah Gross, on Cross Street; finally, in
+October 1753, he purchased land on Tileston and North Bennett Streets
+from John Grant.[88]
+
+Halsy died on January 2, 1767, at the age of 72. In his will dated May
+1, 1766, and probated January 2, 1767, by which his wife Anna was the
+executrix of his estate, he left her the income of his real and personal
+estate. He apparently was survived by three daughters and a son, also
+named James Halsy. He divided his real estate in Boston amongst his
+daughters, and to his son he left land in New Hampshire.[89]
+
+The only known surviving instrument bearing James Halsy's name is a
+wooden surveying compass (fig. 41) in the collection of the Peabody
+Museum in Salem. The engraved compass card is quite similar to the one
+used by Thomas Greenough. In the central medallion is an elaborate royal
+crown, and in the circle around the medallion is inscribed "Made and
+Sold by JAMES HALSY near Ye Draw Bridge in Boston."[90]
+
+[Illustration: Figure 41.--Wooden surveying compass made by James Halsy
+(1695-1767) of Boston. The instrument is 11 in. long. In collection of
+East India Marine Hall, Peabody Museum, Salem, Massachusetts.]
+
+
+_Thomas Greenough_
+
+Contemporary with James Halsy II was Thomas Greenough (1710-1785), who
+was born in Boston in 1710, the son of John and Elizabeth (Gross)
+Greenough. His father was a shipwright in the North End of Boston, and
+one of Thomas's brothers, Newman Greenough, became a sailmaker. Thomas
+also had a sister named Jerusha, who later figured in his real estate
+negotiations.
+
+The earliest known record relating to Greenough is of his marriage in
+1734 to Martha Clarke, daughter of William and Sarah Clarke of Boston.
+Nine children resulted from this marriage over the course of the next 16
+years; four of these were sons. On January 27 of the year of his
+marriage he purchased a house on the northwest side of North Street,
+between Mill Creek and Union Street, from John White and Nathaniel
+Roberts. On August 1, 1736, Greenough purchased the house and land of
+his father-in-law, William Clarke, on the south side of Portland Street.
+On October 28 he mortgaged to his mother his house on Ann Street (which
+appears to have been the house he had purchased on North Street), and at
+the same time he deeded to his brother Newman all his right and title in
+his father's estate at the North End. Greenough was only 24 at the time
+of his marriage, and he apparently became involved in real estate, by
+choice or by necessity, to a considerable degree.
+
+Greenough, in 1744, was a member of a militia company in Boston,[91] and
+three years later, in 1747, he was listed as third sergeant. He was a
+firm patriot, held a town office, and was a founder and deacon of the
+New Brick Church in Boston.
+
+Greenough had a substantial interest in the holdings of his late
+father-in-law. For example, on August 11, 1744, he and his wife deeded
+to a merchant named James Pitts the seawall, or new wharf, "before the
+Town of Boston in the front and rear lying to the northward of King
+Street Pier, North Wharf and flats of James Bowdoin," all of which was
+part of the estate of his deceased father-in-law that apparently had
+been inherited by his wife. In the following year, on November 1, 1745,
+he purchased a house and land on Portland Street from his widowed
+mother-in-law and then on March 31, 1746, he and his wife deeded the
+same house and land to a merchant named Stephen Hall. Numerous other
+negotiations of the same nature are on record.
+
+At some time between 1748 and 1750 Greenough's first wife, Martha, died,
+and in 1750 he married Sarah Stoddard. Three more children, all sons,
+resulted from this second marriage. His real estate negotiations
+continued full pace during the second marriage as during the first.[92]
+
+Greenough's second wife preceded him in death, and Greenough died in
+1785 at the age of 75. His will, probated on August 23, 1785, had been
+made on May 21, 1782;[93] it contained some interesting bequests:
+
+ Executors: my two sons, David S. and William Greenough. Legatees:
+ to the children of my son Thomas, deceased, Rachel, Ann, and Sally
+ Greenough, £13.6.8 each. To their sister Betty £5. To the children
+ of my son John deceased, 200 acres of land. I also give his eldest
+ son John my silver can, fellow to the one I gave his father. To his
+ sons Wm. and David, and to his daughters, Sarah, Abigail, and
+ Mehitible £5 each and the house they live in. My daughter, Sarah
+ Edwards, £10 and a silver chafing dish. My daughter Martha Stone
+ all my lands in the County of York, Cape Porpoise, and Wells, and
+ my silver salver, and her son Thomas £5 and a silver porringer. My
+ daughter Elizabeth Brooks £10 and a silver tea pot. My daughter
+ Mary Savage £40 and to her son Thomas one silver porringer. To the
+ children of my daughter Jerusha, deceased, Martha Clark Lepear and
+ Sally Lepear each of them, £50, and a pair of salt shovels, and a
+ pepper box, silver. All the rest of my estate to my two sons, David
+ Stoddard Greenough, and Wm. Greenough. The late Shute Shrimpton
+ Yeoman, Esq., left an estate to my late spouse Sarah, and to her
+ children, in the Island of Antigua. In case my son David should
+ have a legal possession of same, and Wm. no part, in that case I
+ give my son David £100 and sundry pieces as per schedule amount to
+ £63.11.3. All the rest of my estate to my son, William Greenough.
+
+Of particular interest with relation to Greenough's business in
+instruments is the following advertisement that appeared on May 11,
+1742, in _The Boston Gazette_:
+
+ To be sold by Capt. Cyprian Southack at his House near the Orange
+ Tree and at Mr. Tho. Greenough's Mathematical Instrument Maker near
+ the Draw Bridge, said Southack's Char[t]s of the Coast from Sandy
+ Point of New York to Canso.
+
+Invaluable for this study are Thomas Greenough's manuscript accounts
+that have survived in the collections of the Massachusetts Historical
+Society. The following itemized entries are selected from Greenough's
+business accounts over a period of two decades to provide data on the
+prices current in the second half of the 18th century for new
+instruments and for repairing others:
+
+ In Account with Thomas James Gruchy:
+ 1754, April 27: 1 Compass for the Schooner _Sea Flour_ £0.8.0.
+ 1758, Nov. 28: 1 Spyglass £1.13.8.
+ 1759, Jan. 25: Mending 3 Compasses for the Schooner
+ _Susanna_ £0.6.0.
+
+ In Account with Nathaniel Bethune:
+ 1760, August: A gauging rod £0.6.0.
+ Mending a telescope £0.3.0.
+
+ In Account with Captain McAndrew Mirick of Nantucket:
+ 1772, March 21: For 2 compasses, 1 leaded £0.16.8.
+
+ In Account with Captain Roberson Crockett:
+ 1773, April: For mending 2 Compasses £0.6.2.
+ For mending 1 Hanging Compass £0.3.2.
+
+ In Account with Captain Reworth of the Brig _Fortune_:
+ 1774, March 30: For mending 2 compasses & Glasses £0.7.0.
+
+ In Account with Captain Thomas Godfrey:
+ 1774, April 7: For 1 Telescope £0.8.0.
+
+Other documents in the same collection indicate that Greenough's
+business interests were substantial and not limited merely to the
+construction of instruments. On July 31, 1769, Greenough's name appeared
+on the Boston Citizens' Non-Importation Agreement. Subsequently, on
+December 14, 1774, there is Greenough's signed receipt, with the amount
+left blank, stating that he had "REC'D. of Capt. Thomas Godfrey the Sum
+of ---- in full for my Negro man Cuffes Shair in the Whaling Voige
+----."

+
+Greenough apparently was succeeded in business by his son William
+Greenough. Mr. Lawrence B. Romaine of Middleboro, Massachusetts, in 1939
+described a wooden surveying compass with its own hand-whittled tripod
+made of oak which bore a compass card inscribed "Made by William
+Greenough, Boston, N.E."[94] The compass was protected by a pine cover
+that fitted closely between the sights. The present location of this
+instrument is not known, but it appears to be the only known example by
+William Greenough made of wood.[95]
+
+[Illustration: Figure 43.--Wooden surveying compass, made and sold by

+collection of Franklin Institute, Philadelphia.]
+
+In the Greenough family at the present time is a brass surveying compass
+(fig. 42) of fine quality and of the period before or during the
+American Revolution. The dial is finely engraved with a Tudor rose at
+its center, and around it is the inscription "THOMAS GREENOUGH BOSTON
+Fecit." The compass face is mounted to the main blade with two copper
+rivets. The holding screws for the vane and tripod mounting are rather
+crudely hand cut with wing-nut ends.[96]

+Maine, in 1762. Loaned to the U.S. National Museum by Laurits C. Eichner
+of Clifton, New Jersey. USNM 315001.]
+
+Five other surveying compasses made by Thomas Greenough are known, and
+all are made of wood: the one in the Franklin Institute is made of gum
+(fig. 43), one in Old Sturbridge is made of maple, one in the Bucks
+County Historical collection at the Mercer Museum is made of cherry, one
+owned by this writer is made of basswood, and one on loan to the U.S.
+National Museum from Mr. Laurits C. Eichner is made of hickory (fig.
+44).
+
+The compass at the Mercer Museum forms part of the surveyor's gear used
+to lay out the town of Weymouth, Massachusetts. The example in hickory
+on loan to the U.S. National Museum, as is usually the case with the
+compass cards of the Thomas Greenough instruments, has the central ring
+printed in gilt, and the inscription has turned black, making the
+inscription almost illegible. This specimen was owned by Joseph Frye,
+who was given a land grant in what is now Fryeburg, Maine, in 1762. He
+allegedly used this compass for surveying that land. In 1783 he
+assembled a manuscript book of tables (see fig. 45) for use in
+surveying for his son Joseph Frye, Jr. This manuscript also is part of
+the loan to the U.S. National Museum.[97]
+

+
+The compass card in each of these five instruments is identical,
+designed for use in the mariner's compass (see fig. 46). A gentleman in

+
+
+_William Williams_
+
+Although not one of the earliest instrument makers in Boston, but
+certainly one of the more significant, was William Williams
+(1737/8-1792). He was the son of Capt. John Williams, a shopkeeper who
+died on March 22, 1748, at the age of 41, and who was buried in King's
+Chapel Burial Ground.[98]
+
+William Williams was born in 1737 or 1738. He was ten years of age when
+his father died, and he had two brothers and two sisters. His father
+left a substantial estate of £6,575, of which £4,544/9/4 was for the
+inventory of the shop merchandise. One of the appraisers for his estate,
+Jotham Maverick, married the widowed Mrs. Williams less than a year
+later, on January 20, 1748/9.[99]
+
+In 1770 William Williams established himself as a mathematical
+instrument maker and clockmaker at No. 1 Long Wharf, at the Crown Coffee
+House, as it was then known. The shop was located on the corner of State
+and Chatham Streets, on premises owned by Robert Shillcock.
+
+[Illustration: Figure 47.--Quadrant, showing signature of Thomas
+Greenough. Photo courtesy Connecticut Historical Society, Hartford.]
+
+Williams may have worked as an instrument maker in Marblehead before
+returning to his native Boston. According to Felt,[100] an instrument
+maker named William Williams at Marblehead advertised in the Salem
+newspapers in the early 1770's. However, in 1768 Williams was producing
+instruments from an address in King Street, Boston. (See figure 48.) An
+advertisement inserted by Williams appeared in the March 12, 1770, issue
+of _The Boston Gazette_. It was this same issue that reported the Boston
+Massacre. One of the victims was Williams' step-brother Samuel Maverick,
+the son of his stepfather Jotham Maverick by a first marriage.
+
+In 1773 Williams married Joyce Shillcock, the daughter of his landlord.
+During the Revolutionary War, Williams saw active service as a private
+in Captain Mills' company, of Col. Jeduthan Baldwin's regiment of
+artificers, during the years 1777-1779. In 1780 he served in Captain
+Pattin's company of General Knox's artillery, which was stationed at
+West Point.[101]
+
+With the conclusion of the war Williams returned to the craft of
+instrument-making in his shop, at No. 1 Long Wharf. In 1782 his wife,
+Joyce, inherited the property from her mother, the widow Hannah
+Shillcock, following the latter's death in that year. In the following
+May it is recorded that Williams purchased the warehouse and land on the
+north side of State Street from Benjamin Brown, a trader. By a separate
+deed, he and his wife released to Brown the warehouse and land which had
+been the property of his father-in-law in exchange for a clear title to
+one-half share of the store and land under it "which is next to the
+street called King Street." On February 7, 1784, he bought a share of
+the lower division at Long Wharf, No. 7, from Arnold Welles. On May 17
+of the same year he succeeded in buying out Brown's half share of the
+lower division of Long Wharf at Nos. 1 and 7, and at the same time he
+deeded to Brown one-half share of No. 7 Long Wharf, together with all
+its dockage and wharfage. Finally, on January 20, 1785, Williams and his
+wife deeded to Brown all rights to land of No. 7 Long Wharf, reserving
+for himself his rights in the flats, wharfage, and dockage.
+
+On March 23, 1787, Williams deeded to Joseph Helyer, a blockmaker, the
+store and land under same, and half the wharfage properly belonging to
+Lot No. 1. On October 20 of the same year he sold to Brown a part or
+share of No. 7 Long Wharf, and on March 24, 1788, he purchased land with
+a wooden store at State Street and Long Wharf from Benjamin Brown. On
+June 26 he bought the land and store of Joseph Helyer on the north side
+of Long Wharf.

+
+Williams engaged in only two more transactions before his death. On
+March 28, 1790, he mortgaged to Joseph Greene, a merchant, the land with
+wooden store at the head of Long Wharf on the northeast side of State
+Street; this mortgage was cancelled on May 29, 1793. On October 1, 1791,
+he deeded to Benjamin Brown a one-half share or 1/48th of all the
+dockage and wharfage of Long Wharf that appertained to one-half of Lot
+No. 1, which he had previously purchased from Welles as noted, as well
+as 1/48th of the proprietor's purchase of Gordon's lands and buildings
+adjoining the Wharf.
+
+Williams died on January 15, 1792, at age 44. The administrator of his
+estate was a merchant named Abraham Quincy. By order of the Supreme
+Court, in order to settle his estate, Williams' store building at No. 1
+Long Wharf was ordered sold at public auction. Although on the site of
+the Crown Coffee House, it was a new building erected in 1780 after the
+Coffee House had burned. The purchaser appears to have been John Osborn,
+a merchant, because on May 10, 1793, Quincy, Williams' administrator,
+deeded to Osborn the land with wooden store at Long Wharf on State
+Street.[102]
+
+The only instrument made by Williams which appears to have survived is a
+Davis backstaff (fig. 49) marked "By Wm. Williams, King Street, Boston,
+for Malachi Allen, 1768"; this instrument is now in the collection of
+the Peabody Museum in Salem, Massachusetts. It is to be noted from this
+inscription that this instrument was an early example of Williams' work,
+produced at the age of 20, prior to the opening of his shop at the Crown
+Coffee House.
+
+In 1770, when Williams opened his shop, the carved sign of "The Little
+Admiral" (fig. 37) was installed in front of the Crown Coffee House, and
+Williams' establishment was thereafter designated by this symbol.[103]
+
+In his shop at No. 1 Long Wharf, Williams exercised his crafts of
+instrument-and clockmaking, and he made and sold a large assortment of
+instruments, as well as time glasses which measured from one quarter
+minute to two hours.
+

+"Made by William Williams in King Street Boston" for "Malachi Allen
+1768." In collection of East India Marine Hall, Peabody Museum, Salem,
+Massachusetts.]
+
+The name of Williams appears also in the Day Books of Paul Revere. Under
+date of April 16, 1792, there is the following entry:
+
+ Mr. William Williams Dr
+ To Engravg plate for hatt bills 0-18-0
+ To 2 hund prints 0-6-0.
+
+From June 24, 1792, to January 28, 1797, Revere entered 12 charges
+against Williams for 8,500 hat bills for the total amount of
+£14/15/0.[104]
+
+
+_Samuel Thaxter_
+
+Closely associated with the name of William Williams is that of another
+instrument maker of Boston, Samuel Thaxter (1769-1842). Thaxter was born
+in Hingham, Massachusetts, on December 13, 1769, the son of Samuel and
+Bathsheba (Lincoln) Thaxter. His father, who had been born in Hingham in
+1744, was married on December 27, 1768, and he became the father of six
+children, of whom Samuel was the eldest. Samuel Thaxter, Sr., was
+apparently a man of means, for he is listed as a "Gentleman" and a loyal
+subject of King George. He resided on North Street in Hingham, near Ship
+Street. He died on the island of Campobello at the age of 44 years on
+May 27, 1788.[105]
+
+Samuel Thaxter, as well as several generations of his family before him,
+was born in the old Thomas Thaxter mansion that was built by the settler
+of that name in 1652. During the Revolution Samuel's father, Maj. Samuel
+Thaxter, concealed Tories from the Committee of Safety in a blind
+passage with a secret door in the old house. From there he smuggled them
+to Boston. At the massacre of Fort William, Major Thaxter was one of
+those captured by the Indians. While tied to a tree, he saw two French
+officers, and demanded whether this was the treatment they gave to
+commissioned officers. They allowed him to go free and he dragged
+himself to Fort Edward. Meanwhile, his comrades had reported him missing
+in action, and Dr. Gay preached his funeral sermon in Hingham shortly
+before Thaxter's return. The old Thaxter mansion was torn down in
+1864.[106]
+
+Young Samuel Thaxter moved from Hingham to Boston, where he is first
+heard of in 1792. On June 14, 1792, Thaxter married Polly Helyer, the
+niece of William Williams.
+
+Within a month after the sale of Williams' property at public auction,
+Thaxter acquired the instrument-making business. Apparently the new
+owner of the premises required the business to move, and Thaxter
+established himself at No. 9 Butler's Row. A month after the Williams
+auction Thaxter announced his new location in an advertisement (fig. 50)
+in _The Columbia Centinel_ of May 22, 1793.
+
+Thaxter's new location was a wooden store structure, on the north side
+of Butler's Row that was owned by Andrew Hall and Eunice Fitch in 1798.
+It was in the rear of the north side of State Street, running from
+Merchants Row to the water.
+
+By 1796 Thaxter had moved from this location to No. 49 State Street, on
+the north side opposite to Broad Street, a brick store owned by Joseph
+Lovering & Sons, tallow chandlers. He continued to do business at this
+address until 1815, when he moved to 27 State Street, on the opposite
+side of the street. The new location was in a brick dwelling, opposite
+Merchants Row, that was owned by Joseph Clough, a housewright.
+
+[Illustration: Figure 50.--Advertisement of Samuel Thaxter in _The
+Columbia Centinel_, May 22, 1793. Photo courtesy Harvard University
+Library.]
+
+In about 1825 Thaxter moved his business once more, to 125 State Street,
+the east corner of Broad Street. This building was occupied by Charles
+Stimpson, Jr., a stationer who was one of the publishers of the _Boston
+Annual Advertiser_, which was annexed to the Boston Directory of 1826.
+The building was owned by Jonathan Phillips, the first mayor of Boston.
+In the cellar of the building was a victualler named Augustus
+Adams.[107]
+
+The dominating feature of Thaxter's shop from the time it was opened was
+the carved figure of "The Little Admiral," the trade sign first used by
+Williams.
+
+The firm of Samuel Thaxter eventually became Samuel Thaxter & Son, and
+it continued with that name until past the middle of the 19th century.
+Samuel Thaxter died in April 1842 at the age of 72 years. The entry for
+the firm in the 1843 City Directory listed S. T. Cushing as the new
+owner. From the initials, it seems likely that his full name was
+Samuel Thaxter Cushing, and that he was the grandson of the original
+Samuel Thaxter. S. T. Cushing continued to be listed as the owner of the
+firm until 1899, when he was succeeded by A. T. Cushing, presumably a
+son of the former. The old store was finally demolished in 1901.[108]
+Comparison of a photograph of the building just before its demolition
+with a copy of Thaxter's trade card (fig. 51) of the mid-19th century
+shows that the building underwent little change in the period. The
+"Little Admiral" is barely visible in both views.

+Thaxter of Boston. Length, 13 in.; diameter, 7-1/2 in. Wooden frame
+slides off to permit removal of glass and adjustment of needle. Sighting
+bars are of boxwood. In collection of the writer.]
+
+In 1796, shortly after his marriage, Thaxter made his home on
+
+Fish Street (now North Street), but in 1800 he was living at 54 Middle
+Street (Hanover Street). By 1807 he had moved to a new home on Fleet
+Street. His last home address, at the time of his death, was 41 Pinckney
+Street.[109]
+
+[Illustration: Figure 53.--Compass card from earlier form of wooden
+surveying compass made by Samuel Thaxter of Boston. From an instrument

+
+In the collection of the Massachusetts Historical Society there is a
+receipted bill (fig. 55) from Samuel Thaxter dated July 1, 1801, to Sam
+Brown, for touching up and repairing nine compasses for the French
+corvelle _Berceau_.

+
+
+_John Dupee_
+
+John Dupee of Boston apparently was another instrument maker of the
+pre-Revolutionary period actively engaged in producing wooden surveying
+compasses. Three wooden instruments with his compass card exist in
+private and public collections. The instruments are quite similar: the
+wood in each case is walnut or applewood, with an engraved paper
+mariner's compass card; a schooner at sea is figured within the central
+medallion, and inscribed within the riband enclosing it are the words
+"Made and Sold by JOHN DUPEE Ye North Side of Swing Bridge Boston New
+Eng." One of the instruments is owned by the South Natick
+[Massachusetts] Historical Society; a second example is in the
+collection of the Bostonian Society; and a third is owned by a private
+collector.
+
+There is no record of a maker of scientific instruments or clocks by the
+name of Dupee, although the name John Dupee occurs in the city records
+of Boston during the early decades of the 18th century. An advertisement
+in the February 9, 1761, issue of _The Boston Gazette_ states that
+
+ ISAAC DUPEE, Carver, Advertises his Customers and others, that
+ since the late Fire (on Dock Square) he has opened a shop the North
+ side of the Swing-Bridge, opposite to _Thomas Tyler's_, Esq.; where
+ Business will be carried on as usual with Fidelity and Dispatch.
+
+The natural assumption would be that the three instruments were produced
+in Isaac Dupee's shop after 1761, perhaps by the carver's son. The use
+of an engraved compass card indicates that the instruments were not
+unique, and that a number of others were produced or contemplated. On
+the other hand, it is likely that the maker produced other types of
+instruments utilizing such a card, such as mariner's compasses.
+
+
+_Jere Clough_
+
+Another instrument maker, presumably of Boston, is Jere Clough. The only
+instrument bearing his name known at present is a surveying compass
+(fig. 56), made of wood, in the Streeter Collection of Weights and
+Measures at Yale University. Clough's name does not appear on any of the
+lists of instrument makers or clockmakers, yet it is a name that is
+fairly prevalent in Boston. In 1741, for instance, one Joseph Clough of
+Boston was a maker of bellows. He produced bellows of all types--for
+furnaces, refiners, blacksmiths, braziers, and goldsmiths.[110]
+
+[Illustration: Figure 56.--Wooden instrument made by Jere Clough. In
+Streeter Collection of Weights and Measures, Yale University.]
+
+[Illustration: Figure 57.--Wooden surveying compass made by Andrew
+Newell (1749-1798) of Boston. It is made of mahogany, is 11-1/2 in.
+long, and has a diameter of 5 in. The engraved compass card is signed by
+Nathaniel Hurd, goldsmith, silversmith, and engraver of Boston. In
+collection of Yale University Art Gallery.]
+
+
+_Andrew Newell_
+
+An instrument of considerable significance is another wooden surveyor's
+compass, in the collection of the Yale University Art Gallery. This
+compass (fig. 57) is made of rich brown San Domingo mahogany with
+sighting bars of boxwood. A mariner's card, set into the opening with a
+metal vernier scale, is in the usual form of the mariner's compass card
+of the 18th century; it is executed as a line engraving. A ship and the
+Boston harbor lighthouse are featured in the central medallion. On a
+riband encircling the medallion is the inscription "Made by ANDW. NEWELL
+East End of the MARKET BOSTON," Engraved in script at the southern tip
+of the star is the signature "N. Hurd Sct."
+
+Relatively little is known about Andrew Newell (1749-1798) except that
+he was a maker of mathematical instruments. An entry in the first Boston
+directory, in 1789, listed "Andrew Newell, instrument maker, 61 State
+Street." The directory of 1796 mentioned Newell as having a shop on the
+"East side of the Market," the address that appears on the surveying
+compass.
+
+Two years later the Boston directory listed Andrew Newell and Son, and
+in 1800 the listing included only the name of Joseph Newell, who may
+have been the son. Another mathematical instrument maker named Charles
+Newell may have been another son of Andrew Newell; his name does not
+appear in the city Directory until in the 19th century. An instrument
+with the signature "Newell & Son, Makers, East End of Faneuil Hall,
+Boston" is in the collection of the Bostonian Society.
+
+An important feature of the Newell instrument is the fact that the
+engraver of the compass card was Nathaniel Hurd (1729-1777), the peer of
+goldsmiths and engravers of the colonial period. This compass card is a
+previously unrecorded example of Hurd's work, and constitutes a work of
+art, making the compass a historic scientific instrument.[111] The
+compass was presented to the Yale University Art Gallery by a Yale
+alumnus, Mr. Henry G. Schiff of New York City. No other examples have
+thus far been found.
+
+
+_Aaron Breed_
+
+Aaron Breed (1791-1861) is a relatively unknown maker of mathematical
+instruments who worked in Boston into the 19th century. He specialized
+in nautical, mathematical and optical instruments, with an address at
+173 Broad Street, and another at No. 2 Rowe's Wharf, "At the Sign of the
+Quadrant." Breed made surveying instruments in brass and in wood. A
+brass instrument is in the Henry Ford Museum, and a wooden instrument is
+in the collection of Old Sturbridge Village. The latter is fashioned
+from walnut with an engraved compass card inscribed "Aaron Breed
+Boston."
+
+
+_Charles Thacher_
+
+The name of Charles Thacher appears on the compass card of a wooden
+surveying compass (fig. 58) in the collection of the Mariners' Museum,
+Norfolk, Virginia. No record of this maker has been found, but the
+engraved compass card indicates that he probably worked in New England.
+
+[Illustration: Figure 58.--Wooden surveying compass made by Charles
+Thacher. It is made of cherry or maple; sighting bars are of oak.

+
+
+_Benjamin King Hagger_
+
+Benjamin King Hagger (c. 1769-1834) was the scion of two well-known
+families of instrument makers in New England, so it is not surprising
+that he worked in the same craft.
+
+It is believed that Hagger was born in Newport, Rhode Island, about
+1769, the son of William Guyse Hagger and of a sister of Benjamin King.
+Although his father made instruments--at first in partnership with
+Benjamin King, and then working alone--in Newport at least as late as
+1776, the family appears to have moved after the Revolution. William
+Guyse Hagger's name did not appear in the 1790 census of Newport, and it
+is presumed that he moved with his family to Boston.
+
+Benjamin King Hagger was listed in the first city directory of Boston in
+1789 as "a mathematical instrument maker" with an address on Ann Street;
+he was only 20 years of age at this time.
+
+On November 10, 1793, Benjamin King Hagger, "mathematical instrument
+maker," purchased land with buildings on Prince Street near Snow Hill
+Street from one Peter Greene. Two years later, on December 1, 1795,
+Hagger, now listed simply as a "merchant," purchased a brick house, a
+wooden house, and a shed with land from William Ballard, a tailor of
+Framingham and an heir of Samuel Ballard. The property was located on
+the east side of North Street, south of Mill Creek. At the time of
+purchase, Hagger mortgaged the property to Ballard, and also mortgaged
+to him the house and land previously purchased from Greene.
+
+Hagger was listed as a ship chandler in the following year when on March
+24, 1796, he deeded part of his land on Prince Street to William and
+George Hillman, minors.
+
+On June 22, 1796, three months later, Hagger, now listed as
+"mathematical instrument maker, and ship-chandler" deeded to a mariner
+named Thomas Wallis a house and land that formed part of his original
+purchase near Copp's Hill from Peter Greene. Then on July 21, 1796, he
+purchased from William Ballard all his right to the brick house and land
+on North Street (Ann Street), at the same time mortgaging the property
+to William Ballard, Jr., of Framingham. This mortgage was cancelled on
+April 11, 1798.[112]
+
+These negotiations took place before marriage. A report of the Record
+Commissioners of Boston, states that "William King Hagger of Boston and
+Mehitable Ballard of Framingham were married October 6, 1796." The
+entry appears to be in error because the marriage intentions had read
+"Benjamin King Hagger." It is presumed that Mehitable was the daughter
+of William Ballard, the tailor of Framingham, from whom Hagger had
+bought his house on Ann Street, south of Mill Creek.[113]
+
+Benjamin King Hagger is listed in the city directory of Boston for 1798
+as a "mathematical instrument maker" on Ann Street. This, however, is
+the last listing for his name in Boston, as his name does not appear in
+the 1803 or subsequent directories.
+
+Shortly after 1798 Hagger appears to have left Boston together with his
+wife, and it is probable that he established himself as an instrument
+maker in another Massachusetts community, at present unknown. In about
+1816 Hagger moved with his family to Baltimore and continued his
+instrument-making business.
+
+The records of the 1850 Federal census of Baltimore indicate that two of
+Hagger's sons, John W. and William G. Hagger, had been born in 1800 and
+1806 respectively, in Massachusetts, presumably in the community to
+which Hagger had moved from Boston before moving once more to Baltimore.
+
+According to Matchett's Baltimore directory for 1824, Hagger was a
+"mathematical and optical instrument maker" with a shop at 57 South
+Street. His advertisement in the directory stated that he
+
+ Respectfully acquaints his fellow citizens that he executes all
+ orders in the line of his business with punctuality and confidently
+ professes to give satisfaction to his employers, from the
+ experience of a regular apprenticeship and 37 years practice.
+
+This indicates that Hagger completed his apprenticeship in 1787, when he
+was 18, and since then had been established in his own business or had
+worked for another as a journeyman instrument maker. His first
+advertisement in the Boston directory appeared in 1789, wherein his shop
+was listed as being on Ann Street.
+
+Hagger died in Baltimore on November 8, 1834, at the age of 65, after a
+residence of 18 years in that city.[114]
+
+Thus far only one instrument by Hagger has been found--a wooden
+surveying instrument or semicircumferentor (fig. 59). It is in the
+possession of the writer.
+

+
+
+_Benjamin Warren_
+
+[Illustration: Figure 60.--An advertisement of Benjamin Warren in _The
+Plymouth Journal & Massachusetts Advertiser_. Photos courtesy The
+American Antiquarian Society, Worcester, Massachusetts.]
+
+Production of wooden surveying compasses was not limited to Boston.
+Another instrument maker who produced them was Benjamin Warren (c.
+1740-?) of Plymouth, Massachusetts. The name of Benjamin Warren was a
+fairly common one in Plymouth, being a name handed down in the family
+from father to son for at least five generations before 1800. The first
+Benjamin Warren at Plymouth was married in 1697, and his son Benjamin
+(2) was born in 1698. Benjamin (2) was married in due course, and his
+son Benjamin (3) was born in 1740. The third Benjamin was the father of
+Benjamin (4), who was born in 1766. In 1789 Benjamin (4) married Sarah
+Young, the daughter of Daniel Young, and their son Benjamin (5) was born
+in 1792. The Benjamin Warren who operated the shop in Plymouth probably
+was Benjamin Warren (3), who was then about 45 years of age.[115]
+
+A search of _The Plymouth Journal & Massachusetts Advertiser_ has
+revealed several advertisements and notices (fig. 60) about Benjamin
+Warren from which some information can be derived about the man and his
+business during this period. The first known notice dated March 19,
+1785, probably is the most important one. Later in the same year, on
+August 16, 1785, Warren published the following notice:
+
+ WHEREAS on Friday Morning of the 5th inst. eloped from the House of
+ the subscriber, _Inholder_ in Plymouth, JOHN MOREY, of NORTON, of
+ tall stature, & round shoulder'd. Had on when he absconded, a
+ shabby claret coloured coat, adorned with patches, and a pair of
+ dirty smoak'd coloured breeches; without knee-buckles; and an old
+ flopped hatt, defaced with grease.
+
+ As he appeared to be an enterprising genius, without abilities,
+ politeness or honesty, and went off in an abrupt and clandestine
+ manner; a reward of _Sixpence_ will be paid, to any person or
+ persons, who will persuade or induce the said Morey to make his
+ appearance once more to the subscriber.
+
+It is obvious that Warren was not considerably concerned about the
+return of John Morey, for the reward offered was scarcely conducive to
+obtain the public's cooperation. Warren's first ventures with public
+sales must have been successful, for early in the next year, in the
+issue of January 3, 1786, he announced that
+
+ _Benjamin Warren_,
+
+ PROPOSES to open a convenient AUCTION-ROOM, over the Shop he now
+ trades in, next week. Any Gentlemen that will furnish him with
+ goods of any kind for Public or Private sale, on Commission, shall
+ be served with fidelity, and the smallest favours in that way
+ gratefully acknowledged.
+
+The next notice of the auction-room appeared on February 21, 1786, when
+the newspaper advertised that
+
+ _To-morrow_ will be SOLD, by Public Vendue, At WARREN'S Auction
+ Room,
+
+ A VARIETY of articles, _viz_. Nails, Bar Lead, Glass Pewter,
+ Buttons, Buckles, Chairs, Stands, &c, &c, &c.
+
+ *** The SALE to begin at 10 o'Clock, A.M.
+
+No other notices of public sales appeared in the _Journal_ for the next
+several months. The last notice of this period was another announcement
+of a sale, which was published in the issue of May 30, 1786:
+
+ _Publick Vendue_,
+
+ _At_ WARREN's Auction Room, in PLYMOUTH: at Ten o'clock this
+ morning. WILL be Sold, a quantity of bar lead, boxes of glass, 6 ×
+ 8. English Shovels and Tongs, bridle-Bits, and a variety of other
+ articles of Hard-Ware. Also, a few Anvils at private sale.
+
+Only one instrument signed by Warren is known to survive; it is a wooden
+surveying compass (fig. 61) in the Streeter Collection of Weights and
+Measures at Yale University. The instrument, which appears to have been
+made from walnut, has a compass card with the following inscription
+around the central medallion: "Made and sold by BENJAMIN WARREN Plymouth
+New Eng^d."
+
+[Illustration: Figure 61.--Wooden surveying compass made by Benjamin
+Warren (c. 1740-c. 1800) of Plymouth, Massachusetts, and detail of the
+compass card. The compass, made of cherry wood, is 12 in. long and has a
+diameter of 6 in. In Streeter Collection of Weights and Measures, Yale
+University.]
+
+[Illustration: Figure 62.--Detail of card, Warren surveying compass
+shown in figure 61.]
+
+The medallion (fig. 62) encloses a harbor scene with a brigantine of the
+1740 period off a promontory on which is prominently situated a
+lighthouse with a smaller building partly visible at the left. The
+lighthouse is unusual in construction in that it features twin towers
+rising from a large rectangular wooden building.
+
+As far as can be determined from available records, the only lighthouse
+in America of this period having such construction was the noted Gurnet
+Light, which was built at the tip of Duxbury Beach in Plymouth Bay in
+1768. D. Alan Stevenson[116] relates that the Governor's Council of
+Massachusetts, when it decided in 1768 to erect the Gurnet Lighthouse
+at Plymouth, adopted a novel plan to distinguish it from other American
+lighthouses. "This consisted of double lights set horizontally in the
+same structure. A timber house built at a cost of £660, 30' long and 20'
+high, had a lanthorn at each end to contain two four-wick lamps.
+
+"In 1802 fire destroyed the house but the merchants of the town promptly
+subscribed to replace it by temporary lights, as the Government had no
+immediate funds at its disposal. An Act of Congress of 1802 allotted
+$2500 for building another set of twin lights and reimbursing the
+merchants for their expenditure.
+
+"Though the idea of twin lights at Plymouth seemed an excellent
+distinction from a single navigation light shown at Barnstable harbor in
+the vicinity, they proved not entirely advantageous and a sea captain
+blamed them for causing his shipwreck. He had seen the light from only
+one tower and identified it with confidence as the Barnstable light;
+apparently, from a particular direction one tower hid the other. But
+local prejudice in favor of retaining the twin lights as a distinction
+prevailed until 1924 when, at last, opposition ceased to the
+recommendation which the Lighthouse Board expressed frequently that a
+single light would be preferable."
+
+It seems quite likely that the compass card bears one of the very few
+surviving contemporary representations of the first Gurnet Light in
+Plymouth Bay. A search of the archives of the historical societies in
+Plymouth, Boston, and Worcester and the files of the U.S. National
+Archives has failed to reveal any illustration of this famous
+lighthouse.
+
+Quite by coincidence, the name of Benjamin Warren was discovered among
+the entries of the day books of Paul Revere, the famous patriot,
+silversmith, and engraver. The entry[117] (fig. 63) appears as follows:
+
+ 1786 March 13. Benjm Warren Dr. Plimouth
+ To printing one hundred Compass Cards 0-18-0.
+
+Whether the compass card on the Warren instrument was produced by Revere
+is difficult to determine. Authorities on Revere's engravings agree that
+it could have been engraved by Revere but are unable to state it
+positively. It has been suggested that the entry in Revere's day book
+indicates that he merely printed the compass cards for Warren and that
+he did not engrave a plate. The charge for the work bears out this
+supposition; and furthermore, Revere's bills seemed to make a definite
+distinction between the engraving of plates and actual prints. Whether
+or not Revere was responsible for making the original engraving remains
+to be determined, but it is very probable that he printed the compass
+card of the instrument in the Streeter Collection of Weights and
+Measures at Yale.

+
+_Daniel Burnap_
+
+One of the best known and most respected names among Connecticut
+clockmakers is that of Daniel Burnap (1759-1838) of East Windsor. Burnap
+was born in Coventry in 1759 and served an apprenticeship with Thomas
+Harland, clockmaker of Norwich. In about 1780 Burnap opened his own
+establishment, where he combined the crafts of clockmaking,
+cabinetmaking, and engraving of brass, in all of which he was greatly
+skilled. One of his apprentices was Eli Terry, who later achieved fame
+in the craft in his own right.[118]
+
+Burnap's business included clients in Windsor, Hartford, and Coventry,
+as well as some of the leading merchants and cabinetmakers of the nearby
+cities and towns. Although clockmaking was the primary business in which
+Burnap engaged, he also had a large trade for his surveying instruments,
+silver spoons, gold beads, harness and saddlery hardware, and shoe
+buckles.
+
+Burnap prospered, and in about 1800 he moved back to his native town,
+Coventry. There he purchased a large farm and erected a shop and a
+sawmill, and in due course became the leading citizen of the community.
+He died in 1838, leaving a valuable technological record in the
+completeness of his journals and account books. A study of the entries
+of his day books and ledgers (see fig. 64) reveals that Burnap did a
+substantial amount of business in surveying compasses, chains, and
+protractors. Among his shop equipment after his death there was found an
+unfinished protractor, but no examples of his instruments are known
+except for a compass dial, inscribed with his name, that was discovered
+recently in the collection of a midwestern historical society.[119]
+
+It is significant to note that Burnap made instruments of varying
+quality. For instance, he charged three different prices for his
+surveyor's compasses. The highest-priced compasses cost £6; they were
+made of brass, and were of the more elaborate conventional type used by
+surveyors. A few examples that appeared in his records cost £4; these
+also were made of brass, but probably were of a simpler form. Several
+entries list surveying compasses priced at £2 and £2/8. One of these was
+made for Capt. Solomon Dewie (1750-1813) in September 1790 for £2/8. At
+the same time, Burnap charged him £0/1/6 for touching the needle of
+another compass.[120] The entries in Burnap's account books do not state
+that these inexpensive compasses were constructed of wood, but it seems
+to be sufficiently conclusive that they were.
+
+
+_Gurdon Huntington_
+
+Gurdon Huntington (1763-1804) was not primarily a maker of scientific
+instruments, but he was established as a goldsmith and clockmaker. He
+was born in Windham, Connecticut, on April 30, 1763, the son of
+Hezekiah and Submit (Murdock) Huntington.[121]
+
+[Illustration: Figure 64.--Entry in the manuscript ledgers of Daniel
+Burnap (1759-1838) of East Windsor and Coventry, Connecticut, for sale
+of surveying compass in 1790. Reproduced from the Burnap shop records in
+the collection of Connecticut Historical Society, Hartford.]
+
+The Huntington family was one of the most important in Connecticut
+colonial history. Gurdon's father, Hezekiah, was in service during the
+Revolutionary War, going to Boston as a major with the first troops
+raised in Connecticut. When in Boston he witnessed the miserable
+condition of the arms then in the hands of the soldiers. Major
+Huntington went immediately to Philadelphia, where Congress was in
+session, and proposed to the Congress that he would return to his home
+in Windham and that there he would open a manufactory for repairing
+muskets and other arms. He claimed to have been the first man to have
+made a gun in the Colonies.
+
+Gurdon was too young to have served in the Revolution, but he
+undoubtedly worked in his father's gun manufactory as a boy. In due
+course he learned the trades of goldsmith and clockmaker and established
+his own shop in Windham, which, according to an advertisement (fig. 65)
+in _The Connecticut Gazette_ of June 11, 1784, was "a few rods north of
+Major Ebenezer Backus' store."
+
+On Christmas Day, 1785, Gurdon was married in New London to Temperance
+Williams of Groton. In 1789 their first child, Marvin, was born, and in
+October of the same year the Huntingtons moved from Windham to Walpole,
+New Hampshire. No reason can be found for the move, other than the
+possibility that Gurdon might have anticipated greater opportunity in
+the new community. There he applied himself to his trade as goldsmith
+and clockmaker, but apparently he was not very successful. His family
+grew, and by the time of his death there were eight children. Possibly
+in an effort to supplement his income, Huntington served as postmaster
+of the community. In about 1797, seven or eight years after he had moved
+to Walpole, his father and mother joined him there, and it is believed
+that Major Hezekiah may have worked as a gunsmith during that period.
+Eventually the senior Huntington returned to Windham, Connecticut, where
+he died in 1807.[122]
+
+Meanwhile Gurdon Huntington struggled on until his death on July 26,
+1804. He died insolvent, which created a considerable problem in view of
+the large family he left behind him. Huntington's estate was
+administered by Asa Sibley, a clockmaker in Walpole. Sibley had moved
+to Walpole from his home in Woodstock, Connecticut, in the 1790's and he
+remained there until 1808, when he again returned to Woodstock. Gurdon
+Huntington's widow removed to Bloomfield, Ohio, with her children, and
+she died there on May 25, 1823. Most of her children settled in
+Bloomfield, but several of them moved to New Hartford, New York.

+writer.]
+
+Several examples of Huntington's clocks are known to exist in private
+collections in the United States. However, only one example of his
+scientific instruments appears to have survived. This is a surveying
+compass (fig. 66) made of wood, with brass sighting bars and a painted
+dial under glass with a steel needle. The dial is inscribed "G.
+HUNTINGTON/WALPOLE." The instrument, which is in the collection of the
+writer, is made of cherry wood, with a riveted ball-and-socket joint of
+brass for insertion on a tripod.

+
+_Jedidiah Baldwin_
+
+Jedidiah Baldwin (fl. 1790's) was another early New England clock and
+instrument maker, but little is known of his early life. He was a
+brother of Jabes Baldwin (c. 1777-1829), who worked as a clockmaker in
+Salem and Boston after serving an apprenticeship with Thomas Harland in
+Norwich, Connecticut.
+
+Jedidiah Baldwin also served an apprenticeship with Harland. In 1791 he
+was working in Northampton, Massachusetts, as a member of the firm of
+Stiles and Baldwin, and from 1792 to 1794 he was a member of the firm of
+Stiles and Storrs, in partnership with Nathan Storrs.[123] In about 1794
+Baldwin moved to Hanover, New Hampshire, where he became the local
+postmaster, and where Dartmouth College records his death.
+
+Only one existing instrument is known to have been made by Baldwin; it
+is a wooden surveying compass with a brass dial having two scales, one
+for degrees and one for eight divisions per 90°. The dial is inscribed
+"JED BALDWIN/HANOVER." According to its present owner, Mr. Worth
+Shampeny of Rochester, Vermont, the compass was used for surveying in
+Vermont during the early 1800's.
+
+Another Jedidiah Baldwin worked as a clockmaker in Morrisville, New
+York, from 1818-1820 and then in Fairfield, New York; he appears also in
+the city directory of Rochester, New York, as a clockmaker during the
+years 1834-1844. He may have been a son or grandson of the first
+Jedidiah, or a nephew.
+
+
+_Thomas Salter Bowles_
+
+Thomas Salter Bowles (c. 1765-?) is another elusive New England
+instrument maker about whom little information is available. He is
+believed to have been the son of Deacon Samuel and Hannah (Salter)
+Bowles, born in Portsmouth, New Hampshire, probably between 1765 and
+1770. His father was born in 1739; his mother, who was the daughter of
+Captain Titus Salter, was born in 1748 and died in 1831.[124] Deacon
+Bowles was clerk of the Brick Market in Portsmouth from 1801 to the time
+of his death, November 3, 1802. There is a minimum of information
+available from church and city records in the community, but it is
+believed that he was a member of one of the offshoots of the established
+Puritan Church, and hence he would not appear in its records. He kept
+the lower school in the Brick School House on State Street for a number
+of years.
+
+It is believed that the Bowles family first came to Portsmouth during
+the few years immediately before the beginning of the Revolutionary War.
+It is known that a Thomas Bowles and a Samuel Bowles both signed the
+Association Test on August 14, 1776, promising to oppose the hostile
+proceedings of the British fleets and armies. Furthermore, one of the
+principal taxpayers in Portsmouth in 1770 was a firm named Griffith and
+Bowles, which paid £17 in taxes in 1770. The name of the Bowles who
+formed part of this firm is not known, but it was either Samuel or the
+first Thomas Bowles. The other partner was Nathaniel S. Griffith, a
+watchmaker. It is possible that a tradition of instrument making existed
+in the Bowles family even then.[125]
+
+On file in the office of the City Clerk in Portsmouth are two
+certificates of marriage made out by Thomas Salter Bowles. The first is
+for his marriage to Hannah Ham, a ceremony performed on September 21,
+1809, by Joseph Walton, one of the pastors of a church dissenting from
+the Puritan regime. Hannah was the daughter of William Ham, a brother of
+Supply Ham (1788-1862), a noted local clockmaker. Bowles may have served
+an apprenticeship in that shop before he married Hannah. Two other
+members of the Ham family--George Ham and Henry H. Ham--worked as
+watchmakers in Portsmouth in the same period.
+
+A search of the cemeteries has indicated that Hannah Ham Bowles died in
+1811, age 20. She is buried with her infant son in North Cemetery.[126]
+
+Thomas Bowles's second marriage certificate in Portsmouth is for his
+marriage on September 29, 1813--two years after Hannah's death--to Abiah
+Emerly Bradley of Haverhill, Massachusetts.
+
+Little is known about the work of Bowles as an instrument maker except
+through a few of his instruments. He is listed in the first Portsmouth
+directory, of 1821, as a "mathematical instrument maker" with a place of
+business on Daniel Street; his home was given as Austin Street in
+Portsmouth. He did not appear in the city's directories of 1827 and
+1834. It is assumed that he may have left Portsmouth in the interim,
+possibly to settle in his wife's home town of Haverhill.
+
+Three instruments signed by Bowles have survived, and all show signs of
+considerable wear. They are surveying compasses made of walnut, having
+maple sighting bars and a silvered brass vernier set under the glass.
+Two examples, one in the Streeter Collection of Weights and Measures at
+Yale University and one owned by this writer are almost identical in
+size, form, and details. The only variation is that the Yale example
+(fig. 67) has a bubble level under a brass strip set into one end, an
+item lacking in the other example (fig. 68).
+
+The compass card, made from a line engraving, is identical in each of
+the three examples. A floriated fleur-de-lis on the North point has a
+compass and square at its base, and the name T. S. BOWLES is on a riband
+over it. Adorning the East point is an American eagle bearing a shield
+with stars and stripes and clutching arrows in one claw and a laurel
+twig in the other. In a ring within the central medallion is inscribed
+(see fig. 68), "* T. S. BOWLES * PORTSMOUTH, N.H. *"
+
+[Illustration: Figure 67.--Wooden surveying compass made by Thomas
+Salter Bowles of Portsmouth, New Hampshire. With spirit level. Made of
+birch, the compass is 13 in. long and has a diameter of 6 in. In the
+Streeter Collection of Weights and Measures, Yale University.]
+
+The most interesting of the three instruments was acquired by the
+Dartmouth Museum as part of a collection of the late Frank C. Churchill,
+an inspector in the Indian Service. The instrument (fig. 69) is a
+quarter circle with a compass in its center and sighting bars mounted on
+a swinging arm that reads the angle of the brass scale on the arc by
+means of a vernier. It is mounted on a wooden tripod with the customary
+ball-and-socket joint, which permits it to be placed on a vertical
+plane. A built-in plumb bob at the side helps to establish the
+vertical.[127]
+
+Interesting features of this instrument are two inscriptions engraved on
+the brass strip on the top of the dial. One states that it was "INVENTED
+BY P. MERRILL ESQ." and the other relates that it was "MADE BY JOHN
+KENNARD NEWMARKET." No information about P. Merrill has been found, and
+it is presumed that it was he who conceived the idea of combining the
+various elements into a single instrument and that it was made under his
+direction by Kennard.
+

+Salter Bowles (1765/70-post 1821) of Portsmouth, New Hampshire. Made of

+sighting bars. In collection of writer.]

+
+Some data on Kennard is available in a history of Newfields (formerly
+Newmarket) by Reverend Fitts. John Kennard was born in Kittery, Maine,
+in 1782. He learned the trade of clockmaker in Portsmouth, New
+Hampshire, presumably working with the members of the Ham family or
+others. On July 3, 1806, he married Sarah Ewer. He lived for various
+periods in Nashua and Concord before moving to Newfields in 1812. He
+lived in the Palmer house (which was burned in September 1899), and he
+kept a store in the little community and also served as its postmaster
+from 1822 to 1824. The post office was the only public office in the
+town until the cotton mills were built on the Lamprey River in 1823.
+Kennard later built and occupied the Kennard house on Piscassic Street,
+which was subsequently owned by Jeremiah Towle and has since been
+burned. In December 1830 he established an iron foundry together with
+Temple Paul and the Drake family, but in 1834 he sold his interest to
+Amos Paul and others. He was the father of six children and he died in
+1861. During his lifetime he had specialized in making tall case and
+banjo clocks.[128]
+
+
+
+
+_The New Era_
+
+
+The beginning of the 19th century saw increased trading and shipping
+resulting from the economic development of the new republic, and the
+westward surge brought increased preoccupation with the settlement of
+communities and the development of land areas. As a consequence, the
+demand for instruments likewise increased.
+
+Whereas during the 18th century and until some time after the end of the
+Revolutionary War probably not more than a dozen instrument makers and
+dealers are known to have emigrated from England or elsewhere to make
+their homes and careers in the American Colonies, the beginning of the
+19th century saw substantial numbers of English and French instrument
+makers and dealers immigrate to the United States, to establish shops in
+the major centers of trade.
+
+And whereas the names of scarcely a hundred mathematical-instrument
+makers who worked in the American Colonies during the 18th century are
+known today, the names of hundreds of similar 19th-century craftsmen and
+dealers are to be found.
+
+As Derek Price[129] has so cogently stated: "For scientific instrument
+makers, one need only examine the nineteenth century city directories of
+Boston, Philadelphia and New York to find hundreds of names of craftsmen
+and firms. It is, to be sure, an antiquarian research, for one does not
+expect to find great discoveries coming from these people. But just as
+in Europe, it is a populous trade, influential in the growth of science
+and highly effective in spreading and intensifying the itch for
+ingenious instruments and devices. It is by these men that the basic
+skills of the Industrial Revolution were populated...." By such means
+did American science and technology come of age.

+
+George Adams (1704-1773) was mathematical instrument maker to King
+George III. After serving an apprenticeship from 1718, he made
+instruments for the East India Company in 1735 and 1736, and established
+a shop at "Tycho Brahe's Head" at the corner of Raquet Court, Fleet
+Street. He specialized in terrestrial and celestial globes and
+microscopes. Following his death he was succeeded in business by his son
+George Adams the Younger (1750-1795), who also served as

+
+_Telescope_, consisting of a brass tube 3-1/2 in. long with an aperture
+of 2-3/4 in.; on its original brass tripod, with a serviceable
+altazimuth mounting. Late 18th century. Made by "W. & S. Jones/135
+Holborn/London."
+
+The firm of "W. & S. Jones" was a partnership of two brothers, Samuel
+and William Jones, opticians, who worked at 30 Lower Holborn and at 135
+Holborn in London, from 1793. They bought the copyright to the books of
+George Adams, and subsequently largely carried on the original business
+of the Adams instrument makers.
+
+In _The Journal of Andrew Ellicott_ its author describes this instrument
+as the first of "Two Acromatic Telescopes for Taking signals, with
+sliding tubes, one of them drew out to upwards of 4 feet, and the other
+to about 15 inches, the latter for its length is remarkably good, it
+shows the satellites of Jupiter very distinctly."

+_Transit and Equal Altitude Instrument_, made entirely of brass, with

+
+ Preparatory to beginning the ten mile square [of Washington] a
+ Meridian was traced at Jones' Point on the West of the Potomac.
+ From this Meridian an angle of 45 degrees was laid off North
+ Westerly and a straight line continued in that direction ten
+ miles.... From the termination of this second line a third making a
+ right angle with it was carried South-Easterly ten miles: and from
+ the beginning on Jones' Point a fourth was carried ten miles to the
+ termination of the third. These lines were measured with a chain
+ which was examined and corrected daily, and plumbed whenever the
+ ground was uneven, and traced with a transit and equal altitude
+ instrument which I constructed and executed in 1789 and used in
+ running the Western boundary of the State of New York. This
+ instrument was similar to that described by Le Monnier in his
+ preface to the French "Histoire Celeste." ... All the lines in this
+ city in which I have been concerned were traced with the same
+ instrument which I used on the lines of the ten mile square but as
+ the Northern part was not finished when I left that place, I cannot
+ pretend to say what method has since been pursued.

+_Zenith Sector_ for measuring the angle between a star at its zenith and
+the vertical. Made of brass, with focal length of 6 ft. and an aperture
+of 2-1/2 in. The original lens was made in London about 1780. The
+instrument was made in the old pattern with brass tube and mountings and
+a wooden supporting post. The tube is suspended by trunnions at the top
+and swings against a graduated arc extending north and south for
+measuring zenith distances in the meridian. It is adjusted in the
+vertical by a plumb line whose errors are eliminated by reversing the
+whole mounting about the supporting post. Constructed principally by
+David Rittenhouse, with some modifications by Andrew Ellicott.
+

+the instrument to Captain Duval, from whom it descended to the Hon.
+Anthony Kimmel, who donated it to the U.S. National Museum. USNM 92538.]
+
+In the _Journal of Andrew Ellicott_ its author referred to this sector
+as follows:
+
+ The boundary line to the North of Pennsylvania was fixed by Dr.
+ Rittenhouse and Captain Holland in the year 1774 and completed in
+ 1786 and 1787. We commenced operations by running a guide line west
+ from the point mentioned on the Delaware 20-1/4 miles and there
+ corrected by the following Zenith distances taken at its West
+ termination by a most excellent sector constructed and executed by
+ Dr. Rittenhouse.
+
+The zenith sector is again mentioned in the appendix of the _Journal_:
+"One Zenith Sector of nearly six feet radius similar to the one made by
+Mr. [George] Graham for Dr. Bradley and Mr. Molyneux, with which the
+aberrations of the stars and mutation of the earth's axis were
+discovered, and the quantities determined."

+
+_Zenith Sector_, made of brass, original lens broken. Constructed by
+David Rittenhouse with some additions made by Andrew Ellicott. In The
+_Journal of Andrew Ellicott_ the instrument is described as a Zenith
+Sector of 19 inches radius to be used when the utmost accuracy was not
+necessary, and where the transportation of the large one could not be
+effected without great expense and difficulty. These instruments were
+principally executed by my late worthy and ingenious friend, Mr.
+Rittenhouse, except some additions which I have made myself. The plumb
+lines of both Sectors are suspended from a notch above the axis of the
+instruments in the manner described by the Rev. Dr. Maskelyne, the
+present Astronomer Royal at Greenwich, in the introduction to the first
+volume of his Astronomical Observations. A particular description of
+those instruments is rendered unnecessary by being accurately done in a
+number of scientific works, particularly by M. de Maupertius in his
+account of the measurement of a degree of the meridian under the Arctic
+Circle--The Sector is of all instruments the best calculated for
+measuring zenith distances which come within its arc. The large one
+above mentioned [large Zenith Sector] extends to 5 degrees North, and
+South of the Zenith. Stars when so near the Zenith are insensibly
+affected by the different refractive powers of the Atmosphere arising
+from its different degrees of density. Add to this that the error of the
+visual axis is completely corrected by taking the Zenith distances of
+the stars with the plane, or face of the instrument both East and West.

+_Surveying Compass_, about 1780, made of brass, overall length 13-3/4
+in., diameter of dial 5-1/4 in., silvered bubble level, vernier on
+alidade. The glazed dial, engraved "Rittenhouse & Evans," is fitted with
+a brass cover.
+
+This instrument was made during a brief partnership between David
+Rittenhouse and David Evans, a clock- and watchmaker of Philadelphia and
+Baltimore. It was one of several owned and used by John Johnson in 1818
+for surveying the boundaries between Canada and Maine.
+
+The survey, made in compliance with the Treaty of Ghent, is described in
+_The Collections of the Maine Historical Society_ (Portland: Hoyt, Fogg
+& Donham, 1881, vol. 8, p. 20):
+
+ Thomas Barclay, of whom we have heard more than once before, as a
+ Commissioner under the treaty, on the part of Great Britain, and
+ Cornelius P. Van Ness, on the part of the United States, were
+ appointed Commissioners to ascertain and run the line. An actual
+ survey was arranged, and surveyors appointed, to wit: Charles
+ Turner, Jr., on the part of the United States, and Colin Campbell
+ on the part of Great Britain. About twenty miles of the line was
+ surveyed, then the work was discontinued, never to be resumed; but
+ an exploring survey was commenced by Colonel Bouchette, on the part
+ of Great Britain, and John Johnson, on the part of the United
+ States. These gentlemen made an exploring line in 1817, extending
+ ninety-nine miles from the monument at the head of the river St.
+ Croix, and made separate reports of their doings. In 1818 Mr.
+ Johnson, with Mr. Odell, who had taken the place of Col.
+ Bouchette, finished running the exploring line to the Beaver or
+ Metis River....

+THE FULL PROJECT GUTENBERG LICENSE
+PLEASE READ THIS BEFORE YOU DISTRIBUTE OR USE THIS WORK
+
+To protect the Project Gutenberg-tm mission of promoting the free
+distribution of electronic works, by using or distributing this work
+(or any other work associated in any way with the phrase "Project
+Gutenberg"), you agree to comply with all the terms of the Full Project
+Gutenberg-tm License (available with this file or online at
+http://gutenberg.org/license).
+
+
+Section 1. General Terms of Use and Redistributing Project Gutenberg-tm
+electronic works
+
+1.A. By reading or using any part of this Project Gutenberg-tm
+electronic work, you indicate that you have read, understand, agree to
+and accept all the terms of this license and intellectual property
+(trademark/copyright) agreement. If you do not agree to abide by all
+the terms of this agreement, you must cease using and return or destroy
+all copies of Project Gutenberg-tm electronic works in your possession.
+If you paid a fee for obtaining a copy of or access to a Project
+Gutenberg-tm electronic work and you do not agree to be bound by the
+terms of this agreement, you may obtain a refund from the person or
+entity to whom you paid the fee as set forth in paragraph 1.E.8.
+
+1.B. "Project Gutenberg" is a registered trademark. It may only be
+used on or associated in any way with an electronic work by people who
+agree to be bound by the terms of this agreement. There are a few
+things that you can do with most Project Gutenberg-tm electronic works
+even without complying with the full terms of this agreement. See
+paragraph 1.C below. There are a lot of things you can do with Project
+Gutenberg-tm electronic works if you follow the terms of this agreement
+and help preserve free future access to Project Gutenberg-tm electronic
+works. See paragraph 1.E below.
+
+1.C. The Project Gutenberg Literary Archive Foundation ("the Foundation"
+or PGLAF), owns a compilation copyright in the collection of Project
+Gutenberg-tm electronic works. Nearly all the individual works in the
+collection are in the public domain in the United States. If an
+individual work is in the public domain in the United States and you are
+located in the United States, we do not claim a right to prevent you from
+copying, distributing, performing, displaying or creating derivative
+works based on the work as long as all references to Project Gutenberg
+are removed. Of course, we hope that you will support the Project
+Gutenberg-tm mission of promoting free access to electronic works by
+freely sharing Project Gutenberg-tm works in compliance with the terms of
+this agreement for keeping the Project Gutenberg-tm name associated with
+the work. You can easily comply with the terms of this agreement by
+keeping this work in the same format with its attached full Project
+Gutenberg-tm License when you share it without charge with others.
+
+1.D. The copyright laws of the place where you are located also govern
+what you can do with this work. Copyright laws in most countries are in
+a constant state of change. If you are outside the United States, check
+the laws of your country in addition to the terms of this agreement
+before downloading, copying, displaying, performing, distributing or
+creating derivative works based on this work or any other Project
+Gutenberg-tm work. The Foundation makes no representations concerning
+the copyright status of any work in any country outside the United
+States.
+
+1.E. Unless you have removed all references to Project Gutenberg:
+
+1.E.1. The following sentence, with active links to, or other immediate
+access to, the full Project Gutenberg-tm License must appear prominently
+whenever any copy of a Project Gutenberg-tm work (any work on which the
+phrase "Project Gutenberg" appears, or with which the phrase "Project
+Gutenberg" is associated) is accessed, displayed, performed, viewed,
+copied or distributed:
+
+This eBook is for the use of anyone anywhere at no cost and with
+almost no restrictions whatsoever. You may copy it, give it away or
+re-use it under the terms of the Project Gutenberg License included
+with this eBook or online at www.gutenberg.org/license
+
+1.E.2. If an individual Project Gutenberg-tm electronic work is derived
+from the public domain (does not contain a notice indicating that it is
+posted with permission of the copyright holder), the work can be copied
+and distributed to anyone in the United States without paying any fees
+or charges. If you are redistributing or providing access to a work
+with the phrase "Project Gutenberg" associated with or appearing on the
+work, you must comply either with the requirements of paragraphs 1.E.1
+through 1.E.7 or obtain permission for the use of the work and the
+Project Gutenberg-tm trademark as set forth in paragraphs 1.E.8 or
+1.E.9.
+
+1.E.3. If an individual Project Gutenberg-tm electronic work is posted
+with the permission of the copyright holder, your use and distribution
+must comply with both paragraphs 1.E.1 through 1.E.7 and any additional
+terms imposed by the copyright holder. Additional terms will be linked
+to the Project Gutenberg-tm License for all works posted with the
+permission of the copyright holder found at the beginning of this work.
+
+1.E.4. Do not unlink or detach or remove the full Project Gutenberg-tm
+License terms from this work, or any files containing a part of this
+work or any other work associated with Project Gutenberg-tm.
+
+1.E.5. Do not copy, display, perform, distribute or redistribute this
+electronic work, or any part of this electronic work, without
+prominently displaying the sentence set forth in paragraph 1.E.1 with
+active links or immediate access to the full terms of the Project
+Gutenberg-tm License.
+
+1.E.6. You may convert to and distribute this work in any binary,
+compressed, marked up, nonproprietary or proprietary form, including any
+word processing or hypertext form. However, if you provide access to or
+distribute copies of a Project Gutenberg-tm work in a format other than
+"Plain Vanilla ASCII" or other format used in the official version
+posted on the official Project Gutenberg-tm web site (www.gutenberg.org),
+you must, at no additional cost, fee or expense to the user, provide a
+copy, a means of exporting a copy, or a means of obtaining a copy upon
+request, of the work in its original "Plain Vanilla ASCII" or other
+form. Any alternate format must include the full Project Gutenberg-tm
+License as specified in paragraph 1.E.1.
+
+1.E.7. Do not charge a fee for access to, viewing, displaying,
+performing, copying or distributing any Project Gutenberg-tm works
+unless you comply with paragraph 1.E.8 or 1.E.9.
+
+1.E.8. You may charge a reasonable fee for copies of or providing
+access to or distributing Project Gutenberg-tm electronic works provided
+that
+
+- You pay a royalty fee of 20% of the gross profits you derive from
+ the use of Project Gutenberg-tm works calculated using the method
+ you already use to calculate your applicable taxes. The fee is
+ owed to the owner of the Project Gutenberg-tm trademark, but he
+ has agreed to donate royalties under this paragraph to the
+ Project Gutenberg Literary Archive Foundation. Royalty payments
+ must be paid within 60 days following each date on which you
+ prepare (or are legally required to prepare) your periodic tax
+ returns. Royalty payments should be clearly marked as such and
+ sent to the Project Gutenberg Literary Archive Foundation at the
+ address specified in Section 4, "Information about donations to
+ the Project Gutenberg Literary Archive Foundation."
+
+- You provide a full refund of any money paid by a user who notifies
+ you in writing (or by e-mail) within 30 days of receipt that s/he
+ does not agree to the terms of the full Project Gutenberg-tm
+ License. You must require such a user to return or
+ destroy all copies of the works possessed in a physical medium
+ and discontinue all use of and all access to other copies of
+ Project Gutenberg-tm works.
+
+- You provide, in accordance with paragraph 1.F.3, a full refund of any
+ money paid for a work or a replacement copy, if a defect in the
+ electronic work is discovered and reported to you within 90 days
+ of receipt of the work.
+
+- You comply with all other terms of this agreement for free
+ distribution of Project Gutenberg-tm works.
+
+1.E.9. If you wish to charge a fee or distribute a Project Gutenberg-tm
+electronic work or group of works on different terms than are set
+forth in this agreement, you must obtain permission in writing from
+both the Project Gutenberg Literary Archive Foundation and Michael
+Hart, the owner of the Project Gutenberg-tm trademark. Contact the
+Foundation as set forth in Section 3 below.
+
+1.F.
+
+1.F.1. Project Gutenberg volunteers and employees expend considerable
+effort to identify, do copyright research on, transcribe and proofread
+public domain works in creating the Project Gutenberg-tm
+collection. Despite these efforts, Project Gutenberg-tm electronic
+works, and the medium on which they may be stored, may contain
+"Defects," such as, but not limited to, incomplete, inaccurate or
+corrupt data, transcription errors, a copyright or other intellectual
+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.
+
+1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
+of Replacement or Refund" described in paragraph 1.F.3, the Project
+Gutenberg Literary Archive Foundation, the owner of the Project
+Gutenberg-tm trademark, and any other party distributing a Project
+Gutenberg-tm electronic work under this agreement, disclaim all
+liability to you for damages, costs and expenses, including legal
+fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT
+LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE
+PROVIDED IN PARAGRAPH 1.F.3. YOU AGREE THAT THE FOUNDATION, THE
+TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE
+LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR
+INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH
+DAMAGE.
+
+1.F.3. LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a
+defect in this electronic work within 90 days of receiving it, you can

+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at http://www.pglaf.org.

+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit http://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including checks, online payments and credit card donations.
+To donate, please visit: http://pglaf.org/donate

+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:
+
+ http://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.
