Produktbeschreibung
Excerpt from Results of Spirit Leveling in California, Vol. 255: 1896 to 1907, Inclusive All results of spirit leveling in California for the years 1896 to May, 1907, including that previously reported upon in Appendixes to Reports of the Director of the United States Geological Survey and in Bulletin No. 185 are herein given, readjusted and rearranged by quadrangles. Descriptions and elevations of bench marks are given for 42 counties, furnishing vertical control for one-third of the State. The leveling since 1903 in the Sacramento Valley, in Colusa, Contra Costa, Glenn, Sacramento, Solano, San Joaquin, Tehama, and Yolo counties, was done in cooperation with the State. The field work was done under the direction of Mr. R. U. Goode, geographer, 1896 to June, 1903, and under Mr. E. M. Douglas, geographer, since that date. The work of 1904 to 1907, inclusive, was mostly done under the immediate supervision of Mr. R. B. Marshall, geographer, chief of section. Credit is given in the heading of each list to the various topographers and levelmen directly in charge. The office work of adjustment was done principally by Messrs. L. C. Fletcher and D. H. Baldwin, topographers, under the supervision of Mr. S. S. Gannett, geographer in charge of the triangulation and computing section. The lists are separated into two classes, precise and primary, distinguishing the degree of refinement in the method of leveling employed.
