LETTER OF TRANSMITTAL. 
Department of the Interior, 
United States Geological Survey, 
Hydrographic Branch. 
Washington, I). C, February 13, 1905. 
Sir: I have the honor to transmit herewith a manuscript entitled 
''Record of Deep Well Drilling for 1904, " prepared by Messrs. M. L. 
Fuller and E. F. Lines, but including- certain material compiled from 
notes furnished by Mr. A. C. Veatch. The report presents the results 
of the first six months' work, with a system for the collection of well 
records and samples, formulated by Mr. Veatch and put in operation 
under the direction of Mr. Fuller, chief of the eastern section of the 
division of hydrology, on July 10, 1901. Mr. Veatch was assisted by 
Mr. Lines until September 15, when the work was relinquished to the 
latter. The report embodies the records of a large number of wells, 
for many of which sets of samples are preserved on file, and in addition 
gives an account of the development of the system and of the methods 
employed. 
The principal aim of the report, as stated in the introduction, is to 
furnish drillers and present or prospective well owners a basis for 
future work and to afford geologists and others a more complete 
knowledge of the rock succession and structure. It is hoped that the 
report will lead to greater appreciation of the value of records by the 
driller and will serve to encourage the preservation of samples. 
Very respectfully, 
F. H. Newell, Chief Engineer. 
Hon. Charles D. Walcott, 
Director ['/</'/<</ States Geological Survey.
