of which are borne by the large estates. For example, there is the 

 experiment station for the Java sugar industry at Pasuruan, two 

 tobacco stations (one at Klaten and one at Medan), two rubber 

 planters' stations (one at Medan and the other at Buitenzorg), a tea 

 experiment station at Buitenzorg, a cinchona station at Pengalengan, 

 a coffee station at Malang, and several others that cover more than 

 one type of culture. 



The " Conspectus of Institutions of Pure and Applied Science in 

 or Concerning the Netherlands' East Indies " contains a formidable 

 list of institutes, laboratories, experiment stations, surveys, and 

 observatories. Under the head of private experiment stations for the 

 agricultural sciences, there are listed six for West Java, three for 

 Central Java, three for East Java, and four for Sumatra (east coast). 

 It is safe to say that more or less sound work in economic entomology 

 has been done at nearly all of these stations, partly under the direc- 

 tion of the central Department of Agriculture and partly by an occa- 

 sionally employed expert, all at the expense of planters' associa- 

 tions. There is, moreover, an Association of Government Agricul- 

 turists in the Netherlands' Indies, and also an Association of Experi- 

 ment Stations' Personnel. 



I had been relying on Dr. W. Roepke, now of Wageningen, for 

 exact information regarding the Dutch East Indies, but, unfortu- 

 nately for my purpose. Doctor Roepke was absent from Holland 

 during 1929 and was unable to comply with my request until May, 

 1930, when he had returned and naturally was overwhelmed with 

 other work. So I wrote what precedes. Now, at the last moment 

 before this goes to the printer, I have received a four-page manu- 

 script from Doctor Roepke, accompanied by a list of 25 writers on 

 one or another aspect of the insect problem in the Dutch East Indies. 

 I believe that it will be best to abstract Doctor Roepke's report in the 

 interest of exactitude, as follows: 



Both the Government and private research laboratories have done 

 and are doing research in applied entomology. The Botanical Garden 

 in Buitenzorg, established in 181 7, employed Dr. C. J. J. Konings- 

 berger, of Utrecht, as Zoologist and Entomologist about 1895. He 

 worked on the insect pests of various tropical crops, especially coffee. 

 Doctor Zimmerman (a German), the Botanist of the Station, worked 

 with him, especially on thrips and insects injurious to rubber plants. 

 Doctor Koningsberger became later the Director of the Zoological 

 Museum and Botanical Garden in Buitenzorg, and later Minister of 

 the Dutch Colonies (in 1925), retiring in 1929.
