I'he people of the State of California, represented in senate and assembly, do

Section 1. Of each of the volumes and maps of the State get^loglcal survey 

 already published, or which may be hereafter published, 100 copies shall be

 to the order of the governor, for gratuitous distribution to the various State 

 and Territorial libraries, to public libraries, and to the libraries of universities, 

 colleges, and learned societies in the United States. 



Sec. 2. One hundred copies of the same may be distributed by the State

Results. — As before noted, the reports of this survey are embodied 

 in three volumes on geology and paleontology, published by the 

 State, and two volumes on the auriferous gravels, published by the 

 Museum of Comparative Zoology at Harvard after Whitney's re- 

 tirement. It was announced by the statement of progress for 1872-7o 

 that a geological map of the whole State had been colored, but it 

 seems not to have been issued. The first volume, or Repoit of Prog- 

 ress and Synopsis of Field Work for 1860-1864, appeared in 1865. 

 This was a quarto of 408 pages. It contained a great amount of 

 descriptive matter relating to the areal geology of various parts of the 

 State, particularly of the Coast Ranges and Sierra Nevada, with a 

 chapter on the mining regions. It was announced on the discovery 

 of a single shell in the rocks of Alcatraz Island that the socalled San 

 Francisco was of undoubted Cretaceous age. The serpentines of 

 Mount Diablo and the San Francisco Peninsula were considered to 

 be metamorphic sediments — a mistake repeated by later observers. 

 ^'^Tiitney was decidedly pessimistic regarding the probability of the 

 occurrence of petroleum on the Pacific coast, and unhesitatingly dis- 

 couraged the promoting of enterprises of this nature. It was due to 

 his stand regarding this particular project that arose, according to his 

 own account, much of the antagonism to the survey from speculators
