22 RECORD OF DEEP WELL DRILLING FOR 1904. [bull. 264. 
extent desirable, and especially to properly file and catalogue them so as to be 
readily available, is impracticable with the present force. This, in addition to the 
advisability of collecting and publishing this information (which seems likely to be 
of considerable economic value), has led Mr. Campbell to suggest to me that I place 
before you the question as to the advisability of employing or assigning some geolo- 
gist or other person who can devote the whole or a large part of his time to the 
work, and who should be given charge, under your supervision, of the work relating 
to oil and gas. 
Some of the duties that might be expected to devolve, in whole or in part, upon 
an assistant geologist or geologist in charge of oil and gas are as follows: 
1. To consult with other geologists and with hydrographers and topographers with 
the view of collecting and filing information relating to deep borings for oil and gas 
obtained by the various field parties of the Survey. 
2. To obtain representative records and information as to structure of all pools as 
far as possible. 
3. To collect and file samples of oil- and gas-bearing rocks, together with other 
characteristic beds encountered, as far as feasible. 
4. To gather together published records and all available unpublished records as 
far as practicable, and to file them in the form of card catalogues which will be avail- 
able to the members of the Survey at all times. 
5. To prepare a bibliography of all oil and gas papers which have appeared in 
scientific publications and, as far as practicable, those which have appeared in trade 
journals up to and including 1900. 
6. To keep a bibliographic catalogue of all oil and gas papers which have appeared 
since 1900 in both scientific and trade journals. 
7. To review oil and gas periodicals and to keep records of developments and 
progress. 
8. To keep a general index map showing the location of the oil and gas fields 
throughout the United States. 
9. To keep State or county maps or topographic maps of the Survey, where avail- 
able, to show the details of the various fields and pools of oil and gas. 
10. To prepare geologic columnar sections for each pool as far as possible. 
1 1. To prepare digests of structure for each pool as far as possible. 
12. To keep a catalogue of all sands and their character and geologic positions as 
far as known. 
13. To prepare correlation tables of the various sands where the information is 
available. 
14. To visit new fields and investigate the geology and determine the structure, 
running levels where necessary. 
15. To visit, collect records, and prepare reports on the oil and gas in quadrangles 
and districts where it is not practicable for the geologist in charge to give his personal 
attention to the problem. 
16. To furnish other geologists with all information as to stratigraphy, structure, 
etc., which is afforded by the samples and by the records and other information 
on file. 
17. To answer inquiries of operators, etc., regarding structure and other points 
relating to oil and gas as far as possible, without divulging confidential information. 
18. To publish immediately in trade journals summaries of the geological knowl- 
edge of the regions of newly discovered pools. 
19. To publish in Survey publications from time to time detailed reports of the 
development, structure, and general geology of new pools or the extensions of old 
pools. 
20. To prepare statistics on production, etc., for the Mineral Resources, if required. 
To summarize, the appointment or assignment of a geologist to take charge of the
