- COMPARISON OF WOODS FOR BUTTER BOXES
-
- BY
-
- G. D. TURNBOW
-
-
-Butter boxes used in shipping and storing butter in California, are
-usually made of spruce which is largely shipped in from other states
-particularly from Washington and Oregon.
-
-With the recent war, however, there came an acute shortage of spruce
-on the Pacific Coast with a corresponding increase in price. The
-commercial manufacturers did some work in an attempt to find a
-substitute for spruce, but the trade did not readily accept a change.
-There was a demand from both the lumber and the butter interests for
-investigation to find a suitable substitute for spruce.
-
-The production of spruce is somewhat limited in California, but there
-is an abundance of white fir and a limited amount of cottonwood
-available. However, the creamerymen have not used white fir and
-cottonwood to any extent for butter containers, on account of the
-belief that these materials would impart a wood flavor to the butter.
-
-Inasmuch as nearly all of the butter made in this State is shipped or
-stored in wooden containers, the use of white fir or cottonwood, would
-mean first, a material saving to the butter manufacturers in marketing
-expense, and second, an opportunity for the lumber interests to use a
-large amount of raw material already available in California, which
-heretofore had been of little commercial value or use.
-
-
-BUTTER ABSORBS ODOR
-
-The volatile fats in butter have the property of absorbing odors,
-which often results in an undesirable flavor. Great care then must be
-exercised in keeping butter from coming in contact with materials that
-will impart a foreign flavor. Butter need be exposed to foreign odors
-only a short length of time before the flavor is permanently affected.
-
-Experiments[A] were conducted, therefore, to determine whether white
-fir or cottonwood would impart a flavor to the butter and also to
-determine the possibility of storing butter in cubes and marketing it
-in 60-pound cases when these woods were used.
-
-[A] This experiment was suggested by Mr. M. B. Pratt, Deputy State
-Forester. Through his coöperation, all box material was furnished by
-the Swayne Lumber Company of Oroville and the Capitol Box Factory of
-Sacramento.
-
-
-CUBE BUTTER IN COLD STORAGE
-
-The butter for cold storage was packed in white fir, cottonwood, and
-spruce containers holding ten pounds each. Both seasoned and unseasoned
-woods were used in each of the three methods of packing.
-
-[Illustration: Fig. 1.—Butter packed in cubes paraffined and parchment
-lined.]
-
-The first set packed with butter were plain unseasoned boxes of each
-of the woods. The second set had the inner surface paraffined before
-packing. The method of paraffining was to invert the box over a steam
-jet and steam thoroughly. This served a double purpose in that it
-opened the pores of the wood and allowed the paraffin to penetrate, and
-the heated surface of the wood kept the paraffin in a liquid condition
-so that it could be put on in a thinner coat than if the paraffin had
-been applied to a cold surface. After the boxes had been allowed to
-drain, the inside was then painted with paraffin at 240° F. This method
-gave a complete covering to the wood, a result which is not always
-obtained by some of the commercial paraffin atomizers. The third set
-was paraffined as above and, in addition, lined with good parchment
-paper so that no butter could come in contact with either wood or
-paraffin (fig. 1). Twenty-three 10-pound boxes were packed in the three
-ways.
-
-They were filled with the butter from one churning which scored 92½
-after being chilled for 24 hours at 50° F. and were shipped immediately
-after the first scoring to a cold storage plant in San Francisco and
-stored at a temperature of 12° F. The butter was scored monthly for six
-months. The summary of the scoring is given in table 1.

-SIXTY-POUND BOXES PACKED FOR MARKET The butter for market was cut into
-two-pound squares, wrapped and packed in 60-pound containers, made of
-white fir, cottonwood and spruce (figs. 2, 3 and 4). The butter was
-stored in a cold room, the temperature of which ranged from 48° to 50°
-F. It was held in storage twenty-eight days, which is within two days
-of the maximum time butter may be held and still sold as fresh butter.
-Butter held over thirty days must be labeled “storage butter.” The
-butter was scored four times during the storage period. The butter used
-was all from the same churning which scored 93 after being chilled for
-twenty-four hours at 50° F.
-
-Table 2 gives a summary of the scores showing the effect upon butter in
-containers with varying treatments. When paraffined, the inside of the

-NAILING OF BOXES
-
-Five-penny cement-coated nails were used in making the boxes.
-Practically no splitting was caused by the nails in unseasoned white
-fir, spruce, or cottonwood. There was very little splitting in seasoned
-cottonwood. The nails, however, caused a slight splitting in the
-seasoned spruce and quite a noticeable splitting in the white fir, but
-not enough in either to cause an appreciable loss.
-
-[Illustration: Fig. 2.—Typical 60-pound white fir boxes showing general
-run of this wood.]
-
-
-CONCLUSIONS
-
-
-Cube Butter in Cold Storage
-
-_Boxes paraffined and parchment lined._—White fir and cottonwood can
-be used in place of spruce for storing butter in cubes, when properly
-seasoned, paraffined, and parchment lined.
-
-Cottonwood is equal to spruce as a butter container. Butter stored in
-cottonwood boxes for six months had an average score of 0.048 of a
-point above spruce treated in the same manner.
-
-[Illustration: Fig. 3.—Method of lining 60-pound boxes with paper.]
-
-[Illustration: Fig. 4.—Parchment wrapped butter in parchment lined
-box.]
-
-White fir may be used very successfully. It scored during the six
-months’ storage only an average of 0.381 of a point below spruce.
-
-In the final scoring, after six months’ storage, none of the cubes
-packed in seasoned, paraffined and parchment lined containers received
-a cut directly due to wood flavor.
-
-Green or unseasoned white fir, cottonwood or spruce, may impart a
-slight wood flavor to the butter when packed in cubes, even though they
-are paraffined and parchment lined. The butter stored in unseasoned
-cubes scored an average of 0.218 of a point below the butter stored in
-seasoned boxes with the same treatment. While the average difference
-was very small, in some cases there was a decided wood flavor which was
-pronounced enough to affect materially the flavor of the butter.
-
-_Boxes paraffined but not parchment lined._—Unseasoned boxes of white
-fir, cottonwood and spruce, paraffined but not parchment lined are not
-entirely satisfactory for storing butter. The butter so stored was
-criticized in practically all cases for wood flavor. Butter stored
-in white fir boxes scored 0.358 of a point lower than that in spruce
-boxes, while butter in cottonwood boxes scored 1.071 lower than that
-in spruce. Storing butter in cubes without parchment lining or in
-cubes carelessly lined with parchment will cause objectionable flavors
-regardless of the wood.
-
-_Boxes neither paraffined nor parchment lined._—Butter allowed to come
-in direct contact with any of the three untreated woods will always
-take up wood flavor. The injury to the flavor is about equal from all
-three woods.
-
-
-Sixty-Pound Boxes Packed for Market
-
-White fir is as good as spruce for 60-pound boxes when seasoned and
-parchment lined, the butter being wrapped in parchment only. Cottonwood
-is not quite as satisfactory as either spruce or white fir, there being
-some criticism on the flavor of the butter.
-
-Butter can be shipped in seasoned white fir or cottonwood boxes, lined
-with ordinary wrapping paper, if the butter is parchment wrapped and
-cartoned. There is no advantage in using parchment paper to line the
-box.
-
-Since there was practically no trouble experienced in the unparaffined
-boxes, there is no advantage in paraffining the inside of the box.
-
-Since the completion of the investigational work, approximately 40,000
-white fir boxes have been used with entire satisfaction for shipping
-butter at the University Farm.

-of this license, apply to copying and distributing Project
-Gutenberg-tm electronic works to protect the PROJECT GUTENBERG-tm

-and may not be used if you charge for an eBook, except by following
-the terms of the trademark license, including paying royalties for use

-easy. You may use this eBook for nearly any purpose such as creation
-of derivative works, reports, performances and research. Project

-
-1.B. "Project Gutenberg" is a registered trademark. It may only be

-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 unprotected by copyright law 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 other than 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 in the United States and
- most other parts of the world 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. If you are not located in the
- United States, you will have to check the laws of the country where
- you are located before using this eBook.
-
-1.E.2. If an individual Project Gutenberg-tm electronic work is
-derived from texts not protected by U.S. copyright law (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

-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

-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 website

-full Project Gutenberg-tm License as specified in paragraph 1.E.1.

- 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 the Project Gutenberg Literary Archive Foundation, the manager 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
-works not protected by U.S. copyright law 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
-receive a refund of the money (if any) you paid for it by sending a
-written explanation to the person you received the work from. If you
-received the work on a physical medium, you must return the medium
-with your written explanation. The person or entity that provided you
-with the defective work may elect to provide a replacement copy in
-lieu of a refund. If you received the work electronically, the person
-or entity providing it to you may choose to give you a second
-opportunity to receive the work electronically in lieu of a refund. If
-the second copy is also defective, you may demand a refund in writing
-without further opportunities to fix the problem.
-
-1.F.4. Except for the limited right of replacement or refund set forth
-in paragraph 1.F.3, this work is provided to you 'AS-IS', WITH NO
-OTHER WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT
-LIMITED TO WARRANTIES OF MERCHANTABILITY OR FITNESS FOR ANY PURPOSE.
-
-1.F.5. Some states do not allow disclaimers of certain implied
-warranties or the exclusion or limitation of certain types of
-damages. If any disclaimer or limitation set forth in this agreement
-violates the law of the state applicable to this agreement, the
-agreement shall be interpreted to make the maximum disclaimer or
-limitation permitted by the applicable state law. The invalidity or
-unenforceability of any provision of this agreement shall not void the
-remaining provisions.
-
-1.F.6. INDEMNITY - You agree to indemnify and hold the Foundation, the
-trademark owner, any agent or employee of the Foundation, anyone
-providing copies of Project Gutenberg-tm electronic works in
-accordance with this agreement, and any volunteers associated with the
-production, promotion and distribution of Project Gutenberg-tm
-electronic works, harmless from all liability, costs and expenses,
-including legal fees, that arise directly or indirectly from any of
-the following which you do or cause to occur: (a) distribution of this
-or any Project Gutenberg-tm work, (b) alteration, modification, or
-additions or deletions to any Project Gutenberg-tm work, and (c) any
-Defect you cause.
-
-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 information page at
-www.gutenberg.org
-
-Section 3. Information about the Project Gutenberg Literary
-Archive Foundation
-
-The Project Gutenberg Literary Archive Foundation is a non-profit
-501(c)(3) educational corporation organized under the laws of the
-state of Mississippi and granted tax exempt status by the Internal
-Revenue Service. The Foundation's EIN or federal tax identification
-number is 64-6221541. Contributions to the Project Gutenberg Literary
-Archive Foundation are tax deductible to the full extent permitted by
-U.S. federal laws and your state's laws.
-
-The Foundation's business office is located at 809 North 1500 West,
-Salt Lake City, UT 84116, (801) 596-1887. Email contact links and up
-to date contact information can be found at the Foundation's website
-and official page at www.gutenberg.org/contact
-
-Section 4. Information about Donations to the Project Gutenberg
-Literary Archive Foundation
-
-Project Gutenberg-tm depends upon and cannot survive without
-widespread 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 www.gutenberg.org/donate
-
-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: www.gutenberg.org/donate
-
-Section 5. General Information About Project Gutenberg-tm electronic works
-
-Professor Michael S. Hart was the originator of the Project
-Gutenberg-tm concept of a library of electronic works that could be
-freely shared with anyone. For forty 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 not protected by copyright 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 website which has the main PG search
-facility: www.gutenberg.org
-
-This website 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.

-<hr class="short" />
-
-<p>Butter boxes used in shipping and storing butter in California,
-are usually made of spruce which is largely shipped in from other
-states particularly from Washington and Oregon.</p>
-
-<p>With the recent war, however, there came an acute shortage of
-spruce on the Pacific Coast with a corresponding increase in price.
-The commercial manufacturers did some work in an attempt to find
-a substitute for spruce, but the trade did not readily accept a change.
-There was a demand from both the lumber and the butter interests
-for investigation to find a suitable substitute for spruce.</p>
-
-<p>The production of spruce is somewhat limited in California, but
-there is an abundance of white fir and a limited amount of cottonwood
-available. However, the creamerymen have not used white fir and
-cottonwood to any extent for butter containers, on account of the
-belief that these materials would impart a wood flavor to the butter.</p>
-
-<p>Inasmuch as nearly all of the butter made in this State is shipped
-or stored in wooden containers, the use of white fir or cottonwood,
-would mean first, a material saving to the butter manufacturers in
-marketing expense, and second, an opportunity for the lumber interests
-to use a large amount of raw material already available in
-California, which heretofore had been of little commercial value
-or use.</p>
-
-
-<h3>BUTTER ABSORBS ODOR</h3>
-
-<p>The volatile fats in butter have the property of absorbing odors,
-which often results in an undesirable flavor. Great care then must
-be exercised in keeping butter from coming in contact with materials
-that will impart a foreign flavor. Butter need be exposed to foreign
-odors only a short length of time before the flavor is permanently
-affected.</p>
-
-
-<p>Experiments<a id="FNanchor_1" href="#Footnote_1" class="fnanchor">[1]</a>
- were conducted, therefore, to determine whether
-white fir or cottonwood would impart a flavor to the butter and also
-to determine the possibility of storing butter in cubes and marketing
-it in 60-pound cases when these woods were used.</p>
-

-<h3>CUBE BUTTER IN COLD STORAGE</h3>
-
-<p>The butter for cold storage was packed in white fir, cottonwood,
-and spruce containers holding ten pounds each. Both seasoned and
-unseasoned woods were used in each of the three methods of packing.</p>

- <div class="caption">Fig. 1.—Butter packed in cubes paraffined and parchment lined.</div>
-</div>
-
-<p>The first set packed with butter were plain unseasoned boxes of
-each of the woods. The second set had the inner surface paraffined
-before packing. The method of paraffining was to invert the box
-over a steam jet and steam thoroughly. This served a double purpose
-in that it opened the pores of the wood and allowed the paraffin
-to penetrate, and the heated surface of the wood kept the paraffin in
-a liquid condition so that it could be put on in a thinner coat than
-if the paraffin had been applied to a cold surface. After the boxes had
-been allowed to drain, the inside was then painted with paraffin at
-240° F. This method gave a complete covering to the wood, a result
-which is not always obtained by some of the commercial paraffin
-atomizers. The third set was paraffined as above and, in addition,
-lined with good parchment paper so that no butter could come in
-contact with either wood or paraffin (fig. 1). Twenty-three 10-pound
-boxes were packed in the three ways.</p>
-
-<p>They were filled with the butter from one churning which scored
-92½ after being chilled for 24 hours at 50° F. and were shipped
-immediately after the first scoring to a cold storage plant in San
-Francisco and stored at a temperature of 12° F. The butter was
-scored monthly for six months. The summary of the scoring is given
-in <a href="#table1">table 1</a>.</p>

-<h3>SIXTY-POUND BOXES PACKED FOR MARKET</h3>
-
-<p>The butter for market was cut into two-pound squares, wrapped
-and packed in 60-pound containers, made of white fir, cottonwood and
-spruce (figs. 2, 3 and 4). The butter was stored in a cold room, the
-temperature of which ranged from 48° to 50° F. It was held in
-storage twenty-eight days, which is within two days of the maximum
-time butter may be held and still sold as fresh butter. Butter held
-over thirty days must be labeled “storage butter.” The butter was
-scored four times during the storage period. The butter used was all
-from the same churning which scored 93 after being chilled for
-twenty-four hours at 50° F.</p>
-
-<p><a href="#table2">Table 2</a> gives a summary of the scores showing the effect upon
-butter in containers with varying treatments. When paraffined, the
-inside of the boxes was painted with the paraffin at 240° F.</p>

-<h3>NAILING OF BOXES</h3>
-
-<p>Five-penny cement-coated nails were used in making the boxes.
-Practically no splitting was caused by the nails in unseasoned white
-fir, spruce, or cottonwood. There was very little splitting in seasoned
-cottonwood. The nails, however, caused a slight splitting in the
-seasoned spruce and quite a noticeable splitting in the white fir, but
-not enough in either to cause an appreciable loss.</p>

-<h3>CONCLUSIONS</h3>
-
-
-<h4>Cube Butter in Cold Storage</h4>
-
-<p><i>Boxes paraffined and parchment lined.</i>—White fir and cottonwood
-can be used in place of spruce for storing butter in cubes, when
-properly seasoned, paraffined, and parchment lined.</p>
-
-<p>Cottonwood is equal to spruce as a butter container. Butter stored
-in cottonwood boxes for six months had an average score of 0.048 of
-a point above spruce treated in the same manner.</p>

-
-<p>White fir may be used very successfully. It scored during the
-six months’ storage only an average of 0.381 of a point below spruce.</p>
-
-<p>In the final scoring, after six months’ storage, none of the cubes
-packed in seasoned, paraffined and parchment lined containers received
-a cut directly due to wood flavor.</p>
-
-<p>Green or unseasoned white fir, cottonwood or spruce, may impart
-a slight wood flavor to the butter when packed in cubes, even though
-they are paraffined and parchment lined. The butter stored in
-unseasoned cubes scored an average of 0.218 of a point below the
-butter stored in seasoned boxes with the same treatment. While the
-average difference was very small, in some cases there was a decided
-wood flavor which was pronounced enough to affect materially the
-flavor of the butter.</p>
-
-<p><i>Boxes paraffined but not parchment lined.</i>—Unseasoned boxes of
-white fir, cottonwood and spruce, paraffined but not parchment lined
-are not entirely satisfactory for storing butter. The butter so stored
-was criticized in practically all cases for wood flavor. Butter stored
-in white fir boxes scored 0.358 of a point lower than that in spruce
-boxes, while butter in cottonwood boxes scored 1.071 lower than that in
-spruce. Storing butter in cubes without parchment lining or in cubes
-carelessly lined with parchment will cause objectionable flavors
-regardless of the wood.</p>
-
-<p><i>Boxes neither paraffined nor parchment lined.</i>—Butter allowed to
-come in direct contact with any of the three untreated woods will
-always take up wood flavor. The injury to the flavor is about equal
-from all three woods.</p>
-
-
-<h4>Sixty-Pound Boxes Packed for Market</h4>
-
-<p>White fir is as good as spruce for 60-pound boxes when seasoned
-and parchment lined, the butter being wrapped in parchment only.
-Cottonwood is not quite as satisfactory as either spruce or white fir,
-there being some criticism on the flavor of the butter.</p>
-
-<p>Butter can be shipped in seasoned white fir or cottonwood boxes,
-lined with ordinary wrapping paper, if the butter is parchment
-wrapped and cartoned. There is no advantage in using parchment
-paper to line the box.</p>
-
-<p>Since there was practically no trouble experienced in the unparaffined
-boxes, there is no advantage in paraffining the inside of the box.</p>
-
-<p>Since the completion of the investigational work, approximately
-40,000 white fir boxes have been used with entire satisfaction for
-shipping butter at the University Farm.</p>

-increasing the number of public domain and licensed works that can be

-<div style='display:block; margin:1em 0'>
-The Foundation is committed to complying with the laws regulating
-charities and charitable donations in all 50 states of the United

-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 <a href="https://www.gutenberg.org/donate/">www.gutenberg.org/donate</a>.
