returned to the printer, the corrections are made, and a second and 
Inal page proof is sent to the Survey. This also is submitted to the 
author if he is in or near Washington, but it is not his privilege to 
make further changes. 
(3) When the proof reading has been finished it is necessary in most 
cases to prepare an index to the paper. Occasionally an author prefers 
to make the index, but usually he is more than willing that this tedious 
work should be done in the Survey office. A good index is held in 
high esteem by scientific men, and a large part of the energy of the 
textual force goes into index making. Besides the detailed indexes to 
the individual papers, the textual section prepares and publishes a 
catalogue and general index of all the Survey publications. 
In addition to the work noted in the foregoing paragraphs, which 
relates to the regular series of publications — annual reports (Direct- 
or's, mineral resources, reclamation service), monographs, professional 
papers, bulletins, water-supply and irrigation papers, and geologic 
folios — the textual section edits and reads the proof of all office and 
field circulars and printed forms, which are numerous. 
The following summarized list of the publications of the Survey, by 
years, affords a conspectus of the literary output and of the growth 
thereof during- the existence of the Survev:
