R. Alcorn, field representative of the +Museum. He and his family visited Alberta, British Columbia, the +Yukon Territory and Alaska in an automobile and trailer from June +9, 1947, to September 6, 1947, and again from June 8, 1948, to +August 24, 1948. In 1947, considerable time was spent by Alcorn +in Alaska; trips were made on the Steese Highway to Circle and +on the Glenn Highway to Anchorage. In 1948, most of the collecting +was done in British Columbia and in the Yukon Territory but +a side trip was taken to Haines, Alaska. The collecting stations are +shown in <a href="#fig_1">figure 1</a>. Alcorn's 1,252 specimens include several large +series from areas where few or no mammals had been taken +previously. Time spent at each collecting station was of short duration +(usually less than three days) and although 56 species and +subspecies of mammals are represented in the collections, it is +recognized that not all of the kinds of mammals at any one locality +were taken.</p> + +<p>For the loan of comparative mammalian material, grateful acknowledgment +is made to officials of the following institutions: +California Academy of Sciences; Biological Surveys collection of +the U. S. National Museum; Provincial Museum, Victoria, B. C.; +National Museum of Canada. The promptness of officials of the +game commissions of the provinces and territories concerned, in +providing permits for collecting also is acknowledged. A part of +the funds for field work was made available by a grant from the +Kansas University Endowment Association. Elevations above sea +level are given in feet.

The pallor of some shrews from +east-central Alaska (Chatanika River and Salcha River) suggests +intergradation with the pale <i>S. c. hollisteri</i>.</p> + +<p>Alcorn found the cinereous shrew at most of his trapping stations. +It was captured in mouse traps baited with "chewed" rolled oats; +one was taken in a trap baited with a grasshopper. Rand (1944:35) +and Alcorn each found this shrew to be one of the commoner +mammals along the Alaska Highway, but Alcorn did not find it to be +so abundant as some of the rodents in areas in which he trapped. +The cinereous shrew was taken principally in moist woodlands, +grassy areas, and adjacent to water.

The slightly smaller average size of the +latter specimens indicates a trend toward the smaller <i>S. c. cinereus</i>, +which occurs farther inland.

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 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. Its 501(c)(3) letter is posted at +http://pglaf.org/fundraising.

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. + + +</pre> + +</body> +</html> diff --git a/33915-h/images/fig_1.png b/33915-h/images/fig_1.png Binary files differnew file mode 100644 index 0000000..c69c4a1 --- /dev/null +++ b/33915-h/images/fig_1.png diff --git a/33915-h/images/union_label.png b/33915-h/images/union_label.png Binary files differnew file mode 100644 index 0000000..fcb3cd3 --- /dev/null +++ b/33915-h/images/union_label.png |
