TREASURY DEPARTMENT, _March_ 3, 1883. SIR: I have the honor to acknowledge the receipt of resolution of the House, dated March 3, 1883, requesting that the Secretary of the Treasury furnish, as soon as convenient, to the Speaker of the House copies of documents in the possession of the Treasury Department containing observations on glaciation, birds, natural history, and the medical notes made upon cruises of revenue-cutters in the year 1881. In reply, I transmit herewith the observations on glaciation in the Arctic Ocean and the Alaska region, made by Mr. John Muir; notes upon the birds and natural history of Bering Sea and the northwestern region, by Mr. E. W. Nelson; and medical notes and anthropological notes relating to the natives of Alaska and the northwestern Arctic region, made by Dr. Irving C. Rosse. All these notes were made upon the cruise of the revenue-cutter Corwin in 1881. Very respectfully, H. F. FRENCH, _Acting Secretary_. Hon. J. W. KEIFER, _Speaker of the House of Representatives_. BOTANICAL NOTES ON ALASKA. BY JOHN MUIR. BOTANICAL NOTES. By John Muir. INTRODUCTORY. The plants named in the following notes were collected at many localities on the coasts of Alaska and Siberia, and on Saint Lawrence, Wrangel, and Herald Islands, between about latitude 54° and 71°, longitude 161° and 178°, in the course of short excursions, some of them less than an hour in length. Inasmuch as the flora of the arctic and subarctic regions is nearly the same everywhere, the discovery of many species new to science was not to be expected. The collection, however, will no doubt be valuable for comparison with the plants of other regions. In general the physiognomy of the vegetation of the polar regions resembles that of the alpine valleys of the temperate zones; so much so that the botanist on the coast of Arctic Siberia or America might readily fancy himself on the Sierra Nevada at a height of 10,000 to 12,000 feet above the sea.
