In the Island of Java there are two experiment stations for sugar ; one 

 in East and the other in West Java, and an experiment station for cacao ; 

 all of which are independent of the institution of Buitenzorg. The for- 

 estry bureau situated at Batavia and having charge of the Government 

 forests is also an independent institution, although all of the botanical 

 work of that office is done at the 's Lands Plantentuin by Drs. Koorders 

 and Valeton. These independent investigations form only a very small 

 part of the total investigations now being carried out in Java; all the 

 rest of which are directly under the supervision of Dr. M. Treub and his 

 corps of able assistants, and under the auspices of the 's Lands Planten- 

 tuin at Buitenzorg. 



I have here several acknowledgments to make — to Capt. George P. 

 Ahem for the interest he has taken in identifying this material and in 

 granting me authority to make the trip to Buitenzorg; to F. Lamson- 

 Scribner, Chief of the Bureau of Agriculture, for allowing me so to 

 arrange my work in his Office as to make it possible for me to make 

 the trip ; to Dr. P. van Eomburgh, acting director of the 's Lands Plan- 

 tentuin for granting me access to the library and herbarium of that 

 institution; and to Dr. S. H. 'Koorders, in charge of the forest flora 

 investigation in Java, for aid in identifying some of the more difficult 

 and imperfect specimens, enumerated in Part II of this bulletin.
