lO CARNEGIE INSTITUTION 



experiments may be carried on, and it should be provided with means 

 to make Hmited explorations in the adjacent country to secure mate- 

 rial needed by its investigators. 



A tropical station should reach its highest efficiency when placed 

 under the direction of a competent botanist, who should become a 

 resident in the vicinity of the laboratory. The director should have 

 as an assistant a person trained in the methods of laboratory practice 

 and whose most important duty would consist in securing living ma- 

 terial for the investigators wlio might visit the station. The proper 

 maintenance of the building would require the services of a keeper 

 or superintendent who .should control the work of the laborers and 

 gardeners in the care of the building. 



The laboratory should be organized for a period of five j'ears. 

 With the information at hand accumulated by the former tropical 

 laboratory commission, the director could proceed at once to the selec- 

 tion of a site and the erection of a suitable building. This work and 

 the arrangement of the equipment would consume the greater part 

 of a year, during which period the director only need be employed, 

 the remainder of the staff beginning their duties at the close of the 

 first year. The assistant to the director might, however, profitably 

 begin his duties at any time convenient in the establishment of the 

 station.
