REPORT ON INVESTIfiATIONS MADE IN JAVA IN THE YEAR 1902. 



By Elmer D. Mkkkiii.. 



I. REPORT OF TRIP. 



In accordance with my instructions, I left Manila on September 2, 

 1902, reaching Singapore on the morning of September 8. I left Singa- 

 pore September 9, reaching Batavia on the morning of September 11, 

 and as soon as practicable went to Buitenzorg, but being unable to se- 

 cure hotel accommodations there, returned to Batavia. I remained in 

 Batavia until the morning of September 15, on which date I returned to 

 Buitenzorg. On my first visit to Buitenzorg, September 13, I called on 

 Dr. Van Romburgh, Acting Director of the 's Lands Plantentuin, pre- 

 sented him with Captain Ahern's letter, and outlined the work which I 

 wished to accomplish. Dr. Van Eomburgh very kindly placed at ray dis- 

 posal all the facilities of the herbarium, garden, and library, so that on 

 my return on September 15 I was able to begin work immediately. 



As the chief object of my trip was to identify the botanical specimens 

 in the herbarium of the Forestry Bureau, attention was given first to 

 this work, the results of which are given in Part II, Plantae Ahemianae. 



In addition to determining the above Forestry Bureau material, about 

 300 specimens of my own collection in the herbarium of the Bureau of 

 Agriculture were identified. 



The time from September 15 to November 15, with the exception of 

 two days spent in a trip to Batavia to interview Dr. Bruisma, inspector- 

 general of the forestry bureau for the Island of Java, was spent at Buit- 

 zenborg. This time was taken up for the most part in identifying the 

 botanical material mentioned above, it being too limited to allow for the 

 working out of all the critical species. On November 14, having com- 

 pleted all the work possible in the time allotted to me, I again went to 

 Batavia, sailing that night for Singapore, where T arrived on the morn- 

 ing of November 17. I was obliged to wait for a Manila steamer until 

 November 24. On that date I took the S. S. Kordt for Manila, via La- 

 buan, reaching Manila December 2. 



In addition to my major work in identifying the botanical material 

 mentioned above, a special report has been prepared (Part III) on Dr. 

 Koorders's method of investigating the forest flora of Java, which includes
