REPORT OF THE SECRETARY. 101 



matter being held in abeyance until the work on the collections had 

 been resumed. Books on the various subjects covered have, there- 

 fore, been sought and the number augmented. During the interval, 

 however, the future need of publications for working up the collec- 

 tions was never lost sight of and there was a number of the serials 

 bound and ready for use. Toward the end of the year two cata- 

 loguers were employed in the division of mineral technology to put 

 the books on hand in the very best of order and for the making of a 

 special author and subject catalogue, so that with the close of the 

 year the work has been completed and this sectional library is in 

 excellent condition. It is hoped that during the present year it will 

 be possible to do the same thing for the division of textiles. This 

 will, however, not be possible with the present force, which is too 

 small. 



With the death of Mr. Thomas W. Smillie, who was for many 

 years custodian of the section of photography in the division of 

 graphic arts, it was necessary that all books in the section should be 

 checked up. A special cataloguer was employed for the purpose and 

 the books and pamphlets were put in order and catalogued, periodical 

 series arranged on the shelves and lacking numbers indicated in order 

 that sets could be completed. The work was finished by June 30. 



The following is a complete list of the sectional libraries :
