THIRTEENTH ANNUAL REPORT 17 



Foreig7i accessions. — Extra-Philippine material received by 

 collection, in exchange, and for identification has been greater 

 than in any foregoing year. A total of 5,130 and 12,601 speci- 

 mens for the six months ending December 31, 1913, and for 

 the calendar year 1914, respectively, have been received, poi- 

 soned, mounted, and distributed into the herbarium. Many of 

 the specimens are of the greatest value for purposes of compar- 

 ison, and a large number of cotypes are represented in some 

 of the collections, notably in the material received from the 

 Paris Museum, the largest and most valuable single collection 

 received during the year. 



Total accessions. — The specimens added to the herbarium from 

 all sources to date increase the grand total of the herbarium to 

 149,141, of which about 87,500 are Philippine and 61,655 are 

 extra-Philippine. It is estimated that nearly 3,000 additional 

 specimens, Philippine and extra-Philippine, are on hand, but 

 these have not been entered as the specimens are not yet 

 arranged, numbered, or otherwise prepared for identification. 

 Work on this material is being pushed as rapidly as possible. 



In our cooperative w^ork with the Bureau of Forestry the 

 latter has arranged to install a small herbarium case at each 

 forest station, and we have agreed not only to report the collec- 

 tions by number, giving the Filipino and scientific names and 

 the family to v/hich each species belongs as heretofore, but 

 also to mount and return a duplicate of all botanical material 

 sent in by the foresters, which will be sent to the forest station 

 nearest to the place where the material was collected. Already 

 633 specimens have been mounted and returned. It is believed 

 that this will add greatly to the value of the work done by the 

 rangers and foresters, will stimulate interest on their part in 

 the matter of collecting botanical specimens, and will tend to 

 reduce the duplication of species as foresters and rangers change 

 stations. As in the past, the original set of all material sub- 

 mitted by employees of the Bureau of Forestry is mounted and 

 incorporated in the herbarium of the Bureau of Science. 



The type collection. — Since it was improbable that fireproof 

 quarters for our valuable herbarium could be procured soon, 

 the entire type and cotype collection of 3,500 sheets was placed 

 in special cases in the fireproof east wing of the Bureau of 

 Science building, where it is arranged in families and genera. 

 Each case is one half the size of a standard herbarium case. This 

 size was selected so that the cases, with contents intact, could 

 be removed from the building in case of emergency. Types 

 and cotypes of cellular cryptogams have not been segregated.
