the method of determining the rate of tree growth, prevalence of species 

 of economic importance, t'tf. In Vavi IV there has been imhidcd notes 

 on the Itotaiiiial garden, lihiarv. laltoratories, herbarium, vie. Iv\tensive 

 notes nut iiuliidcd in this k port were also compiled regarding publica- 

 tions, with special rel'ert'nce to those that apply to the Philippines, and 

 niucii libiaiT worl<. looking up references to the Philippine flora, publica-

Some ()()() specimens of tlic botanical material which were taken to 

 Buitenzorg were in duplitatc These were presented to the herbarium of 

 the botanical garden, and in exchange for this material a similar collection 

 of authentically named species in the garden are being prepared for the 

 Forestry Bureau of the Philippine Islands. About 200 specimens were 

 prepared while at Buitenzorg. 



The catalogue of the gardcm was carefully perused and approximately 

 1,000 species were specified, of which specimens were desired. These are 

 now being prepared and will be sent later. All the specimens which were 

 marked are iices or shrubs. The greater part of them are also found in 

 the PhilippiiK's. Tliis material will be of the greatest value as a guide in 

 identifying future Philippine collections. In addition to specimens of 

 the trees and shrubs, I also personally collecte(| specimens .from all the 

 species of grasses growing in the gardens and was allowed to take these 

 specimens from the duplicates of Dr. Koorders's Java collections. These 

 grass specimens will be of very great interest to the herbarium of tlie 

 Bureau of Agriculture. 



From Mr. Bruisma a report of the work of the forestry bureau, a cata- 

 logue of the library of the bureau, a copy of the forestry regulations, and
