Authors Maclure, William
Full Title (Title Page to) Observations on the Geology of the United States, explanatory of a Geological Map. By William Maclure. Read January 20th, 1809. (In) Transactions of the American Philosophical Society, Held at Philadelphia, for promoting Useful Knowledge. Volume VI. Published by C. and A. Conrad and Co. Philadelphia. ... Jane Aitken, Printer. 1809.
List No 2749A
Note 1st edition of the first geological map of U.S. A portion of a map of the U.S. by Samuel Lewis is used to make this map. The full sheet of paper was put on a larger plate and pulled, leaving the upper and right side without borders, as issued. Uncut and untrimmed, the map appears here with Maclure's original essay on the geology of the U.S. In 1817 Maclure published an expanded versus of his essay, using the small Melish Map of the U.S. as a base. Maclure was dissatisfied with the Lewis map because of its rendering of the mountains, and an errata slip is attached to the back of p 423 explaining this (and stating that originally it was intended to use a reduction of the Bradley U.S. map). See Marcou 1858 for more discussion of the Lewis map. Maclure did a Paris printing of the article and Map (using a map by Volney as a base) in 1811, in French. The Lewis map is most likely the Map of the U.S. published in the 2nd edition of Carey's American Atlas, 1809 (P-Maps p 876,Walsh). Maclure's map and essay are very rare. There is an inscription on the title page to "Mons. F.A. Michaux-Paris, from his friend..." Map bound into the back of paper covered boards with the title handwritten on the spine. Map in full color by geologic structure.

List No 5852.167
Note Composite image of a set of 164 spectacular, large format, sharp, black and white vertical aerial photographs partially overlapping images covering San Francisco north of a line approximately between Merced Lake and Candlestick Point. Resolution generally better than one foot and much higher with high contrast features, for example the paint striping on a basketball court. Relative heights frequently discernible based on shadow cast of objects and structures. Handwritten date on index map indicates photographs taken in August, 1938. Owned by the San Francisco Public Library. (Authorship almost certainly incorrectly spelled in handwriting on index sheet as Harrison-Rikker). He married Charlotte Seward in the mid-1920s, after divorcing, he married Esther Miriam Munson in 1936 Aerial Photographer Harrison Clay (Chesley) Ryker (1898-1981) was born in Oakdale, CA. . He served in the U.S. Army for several years in Germany with the post-World War I occupational forces, and partook of educational opportunities at the University of California, Berkeley. Expanding on his hobby in photography, Mr. Ryker teamed with various pilots beginning aerial photography services out of the Oakland Airport and throughout the West. Colleagues included Lage Wernstedt of the U.S. Forest Service. He also worked with the Fairchild Aerial Camera Company (including an aerial survey of Puerto Rico) and Clyde Sunderland of Pacific Aerial Surveys. As well, he took photographs of the devastating 1923 Berkeley Fire, archived in The Bancroft Library. By 1938 Mr. Ryker was listed in business as a map publisher (see Polk's Oakland 1938 Street and Avenue Guide) based at 1924 Franklin St., Oakland. At that time, he had at least one patent pending for a stereoscope used for aerial photograph interpretation. (Note continued in Pub Note field below).
