REPORT OF THE SECRETARY. 29 



tered in preparing and financing the Catalogue. The number of 

 scientific papers being published has greatly decreased and it has 

 been found practically impossible to obtain the necessary scientific 

 and clerical assistance for the preparation of the Catalogue. How- 

 ever, the Central Bureau at London has succeeded in issuing four 

 volumes, the twelfth annual issue of geology, and the thirteenth 

 annual issue of chemistry, anatomy, and botany. This brings the 

 total number of volumes published since the inception of the Cata- 

 logue in 1901, up to 216 volumes containing about 3,000,000 refer- 

 ences to current scientific periodicals. The organization as a whole 

 is holding together very well under extremely adverse conditions, and 

 Avhen peace is declared it will be necessary only to resume, rather 

 than reorganize the work. 



It is becoming more and more difficult to draw the line between pure 

 science and applied science, and the present limitation of the Cata- 

 logue to pure science should be broadened to include at least some of 

 the applied sciences which are advancing with such great strides. 

 Although this would increase the size and cost of the Catalogue, yet 

 its enhanced value would by increasing the demand for it and con- 

 sequently its sale, offset any additional cost, 



Respectfully submitted. 



Charles D. Walcott, Secretary.
