logical work by the lack of a suitably trained Filipino assistant 

 who can devote his whole time to the preparation of material. 



We have a large amount of unmounted material on hand, and 

 we should keep up with the specimens received. One thousand 

 six hundred thirty new insect boxes ordered for the new wing 

 of the building have been received and provide facilities for stor- 

 ing prepared material. 



Accessions. — We have first accessioned rare material and 

 species not represented in our collection. Even taking these 

 facts into consideration, our numbers for the last year begin 

 with 14,408 and end with 17,044, showing an accession of 2,636 

 lots (2,250 lots in 1912), or approximately 13,180 specimens 

 ready for study. 



Donations. — Fr. F. R. Sanchez, S. J., has donated a consider- 

 able number of insects collected either by himself or some of his 

 students at various times and places during the year, many 

 very desirable specimens having been taken at Mount Mirador, 

 Baguio, Benguet, Many other individuals have donated single 

 specimens to the collection. 



Exchange. — Exchanges of insects have been effected with the 

 following : 



G. A. Waterhouse, Sydney, Australia, for Lepidoptera. 

 Germain Beaulieu, Ottawa, Canada, for Lucanidae. 

 M. E. Walsh, Soekaboemi, Java, for Lepidoptera. 



Classification and identification of material. — During the year 

 Mr. Schultze has finished the manuscript of a catalogue of the 

 Coleoptera of the Philippine Islands. 



J. Weise, K. M. Heller, F. Ohaus, W. Horn, H. Gebien, and M. 

 Bernhauer, eminent entomologists, have served us most zealously, 

 both in the identification of material and in the preparation of 

 papers for publication. The identification work is exceedingly 

 important, as a well identified, systematic collection is the work- 

 ing base for economic problems. Our entomological publications 

 which are mentioned elsewhere give full synonymy and literature 

 references of about 2,200 species, and will be most important as 

 an aid in referring to descriptive literature for the identification 

 of Coleoptera with reference to economic questions. 



Silk culture. — Through our efforts, silk culture is steadily in- 

 creasing in the Philippines. It was introduced into at least one 

 new province during the last year. We have been raising our 

 stock of about 10,000 silkworms per generation. As it becomes 

 necessary after some time to introduce new blood, we imported 

 eggs of the monovoltine Japanese white silkworm from Japan
