24 THE BUREAU OF SCIENCE 



Arrangements have been made to have the extensive Chinese 

 collections made by Mrs. Clemens, totaling nearly 4,000 numbers, 

 studied and reported on by European specialists. Preliminary 

 work has been done on the Robinson Amboina collection, and I 

 hope the work can be completed during the present year. 



'Total accessions. — The specimens added from all sources to date 

 increase the grand total of the herbarium to 160,354 mounted 

 specimens, of which 92,357 are Philippine and 67,997 are extra- 

 Philippine. An especially valuable lot of material from Mount 

 Kinabalu, Borneo, was received from Mrs. Clemens just at the 

 end of the year; it is not included in the totals, as there was 

 no time to prepare it. 



Publications. — A list of the papers that have been published 

 in Section C, Botany, of the Philippine Journal of Science is given 

 on page 47. 



SECTION OF ICHTHYOLOGY 



Fish culture carried on by the Bureau of Science has 

 progressed steadily. The black bass, Mycropterus salmoides, 

 brought originally from the United States in 1907, have increased 

 in a satisfactory manner both in Baguio Lake and in the spawn- 

 ing pond built near the Bureau of Science. Lake Lanao was 

 stocked last year with fry from Baguio, and in October bass fry 

 from the Bureau of Science pond were planted in a seldom-fre- 

 quented portion of Laguna de Bay where it is believed they will 

 thrive. The stocking of these lakes with black bass will mean a 

 considerable increase of the available food supply of the respec- 

 tive communities and will be a factor in keeping them free from 

 mosquitoes. Other lakes will be stocked from time to time. The 

 Bureau of Science also has distributed many mosquito fish to 

 those who have applied. There is still an ample stock ready for 

 distribution. The economic fishery industries of the Islands have 

 been stimulated in many ways, and instruction regarding the 

 construction of fish ponds and other information have been given. 

 The fish expert was absent on leave in the United States from 

 May 16 to December 3, 1915, and consequently somewhat less 

 work has been accomplished than in previous years. The services 

 of Mr, A. L. Day, of the University of the Philippines, were 

 secured during the period for carrying on the routine work. 



The fish expert was detailed on December 18, 1915, further 

 to study Philippine pearl fisheries and to cooperate with the 

 Governor of the Department of Mindanao and Sulu in proposing 

 an act regulating the fishing for shells of marine mollusks in 

 waters of the Philippine Islands. An act regulating the
