mittee, and Dr. C. W. Richmond and Dr. Witmer Stone, Editor of 
the Auk, in correcting the proof. Dr. Dwight very generously of- 
fered to look over the entire proof and contributed many critical 
notes and suggestions, and Dr. Richmond corrected the names of 
foreign species and read the proof of the Biographical Index. 
The full committee of 22 members was thus practically divided 
into three subcommittees: an indexing subcommittee of 10 mem- 
bers, a biographical subcommittee of 8 members, and a proof read- 
ing subcommittee of 4 members. While somewhat smaller than the 
committee which prepared the Index of 1907, it included 10 members 
who were especially equipped by reason of the experience gained in 
the former work. 
PROGRESS OF THE WORK 
The basis of this Index was a series of cards prepared by Prof. 
W. W. Cooke in connection with the work of the Biological Survey. 
These cards were rearranged according to volumes, distributed to 
the ten indexers to compare with the text, correct and supplement 
when necessary, each member thus being responsible for one volume. 
After the cards had been corrected they were returned to the secretary 
who arranged them in a single alphabet and had them copied on 
sheets for the press. These sheets were then returned to the indexers 
for comparison with the cards to insure that the copying had been 
done correctly. In this way each entry was checked at least twice. 
Indexing began promptly in February, 1913. By May about one- 
fourth of the cards had been returned, and at the annual meeting in 
November the Committee reported that the copy was nearly finished. 
The winter was devoted to completing the copy and making the final 
corrections. When the Union met in Washington in April, 1914, 
the manuscript was delivered to the editor ready for the press. The 
first proofs were received early in July, but through unforeseen and 
unavoidable delays, the work was not all in type until the middle of 
October, 1914. The necessity for care in correcting the proofs and 
the time consumed in having them looked over by several persons 
still further delayed completion of the proof reading until Decem- 
ber and postponed issue of the work until early in 1915. In compari- 
son with the progress of the former and larger work, the actual 
time consumed in preparing the 10-year Index and putting it through 
the press was 2 years instead of 8 years and it appears 4 years 
instead of 7 years after the last volume to which it refers.
