The followiiifi' iuformation re^ai(liii<i' exporimeiit stations in Java has 

 been furnished by Dr. H. Winter, lor some time chemist of the West 

 Java Sn<iar Experiment Station and later (Mnmected with th«^ station in 

 ]\Ii(hlle Java. Though not statistically complete, it is iK-vcrthclcss ot 

 interest as illustrating the progress of the experiment station enterprise 

 there. 



There are at present hmr ex]>eriment stations on the Island of Ja\ a. 

 Tliree, which may be called sugar experiment stations, were organized 

 and are supi)orted by associations of sugar producers. The fourth, 

 whieh is supported by the Government, is connected with the botanical 

 garden at Buitenzorg, and is devoted to investigations of trojtical ]ilants. 

 especially those of commercial importance in Java. 



Of the three sugar experiment stations, one is situated at Kagok 

 T<'gal in West Java, another at Samarangin Middle Java, and the third 

 at Tassoeroean in East Java. The oldest is the West Java Station, 

 A\liicli was ftmnded in ISS."}. Jt is under the control of an association 

 of some thirty or forty sugar ]»rodncers, w ho furnish the means for its 

 su]iport — about >«1(».0(M» annually — and apjjoint a committee from their 

 number lor its nianagcnient. f'.xcry associate pays in iiro]i«»ition to flic 

 ai-ea he cultivates. .Vt tlie tinu- of its organization the working siall 

 included a direct(U', Dr. W. ivriigei-, and a chemist. The present director 

 is ])r. Went. 



Some of the results of tlu^ investigations at this station have been 

 reported by Dr. Kriiger in Dutch and also in Clerman in a volume 

 entitled lUrivhtv dcr Vcr.suvh.s ,Si<iti(ni fur Znclrrrohr in Wist ■luni. 

 K(((joh- Tcgal {Javtt), published in Dresden, (Jermany, in ls<to. It con 

 tains accounts of three investigations by Dr. Winter and one Iiy Dr. 

 Ivriiger. Of those by Dr. Winter, the tirst, on ^Methods of Invesliga- 

 tion tor the Cane-Sugar Industry, describes stiulies on the determina 

 tion ol" gliu-ose in sugar juices, the determination of sugar in sugar can*', 

 and the select i<ui and investigation of average samjiles in held experi- 

 ments: the seciuid, on Tln' ( 'liemical < 'omjtosition of Sugar < 'ane. treats 

 ot tlie distributi(Ui of sugar in sugar cam' and the chemical c<uistitiu'iits 

 of sugar cane; the third, (Ui l^xtractiou of Cane Sugar from Sugar Cane, 

 contains articles on certain materials which ai»]tear in the nniking ol 

 sugar, and on lime i)n'cii>itation (without CO.). That by Dr. Kriiger 

 is on Diseases and Knemiesof the Sugar Cane, and is in three divisions. 

 The tirst, on diseases due to aninnil parasites, treats of diseases caused 

 by borers and riii/sojxxhc the second, cui diseases due to vegetable jiara- 

 sites, treats of blight, re<l sjxit of the leaves, rust, and a «lisease of the 

 leaves caused by a sclerotium; the third treats of obscure diseases 

 ])robably <lue to vegetable organisms. Among the nine ])lates accom-
