REPORT OF THE SECRETARY. 107 



There were 799 volumes prepared and sent to the Government 

 binder. Of this number 625 were returned to the Museum before 

 the close of the year. 



Gifts. — The following persons have contributed to the collection 

 in the building: Dr. William Healey Dall, Dr. Edgar A. Mearns, 

 Dr. Charles Doolittle Walcott, Dr. Oliver Perry Hay, Dr. F. Alex- 

 ander McDermott, Dr. F. P. Dewey, Dr. Walter Hough, Mr. William 

 E. Maxon, Dr. A. C. Peale estate, and the estate of Dr. Theodore 

 Nicholas Gill. 



Dall Collection. — Dr. William Healey Dall has continued to con- 

 tribute to his collection of books relating to moUusks which he pre- 

 sented some years ago for the sectional library of the division of 

 mollusks. Since July 1, 1915, he has added 207 titles. 



Gill collection. — All the books and pamphlets from the estate of 

 Dr. Theodore Nicholas Gill are being classified and arranged so 

 that they can be properly distributed. From the hasty examination 

 made in looking over the collection as it was being transferred it 

 appears that the Museum library will have a valuable addition to 

 its series of works relating to natural history, especially in ich- 

 thyology. 



Technological series. — In this branch of the library there have 

 been catalogued 1,052 volumes and 2,125 pamphlets, making a total 

 of 3,177. The cards typewritten and filed in connection with this 

 work numbered 3,505, the periodicals entered 3,631. 



The books and pamphlets withdrawn for consultation in connection 

 with the work of the Museum from this part of the library num- 

 bered 537. This is in addition to those borrowed from the central 

 library. 



The filing of cards in the scientific depository set of printed cards 

 from the Library of Congress has been continued. Two thousand 

 and thirty-three author cards and 4,031 subjects cards were placed 

 in the alphabetical series. 



Sectional libraries. — The checking of publications assigned to the 

 sectional libraries has been continued as the other work would allow, 

 and while some progress has been made the work is not near com- 

 pletion. 



The following is a complete list of the sectional libraries:
