lO CARNEGIE INSTITUTION 



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

 to make limited 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 who might visit the statio'n. 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 years. 

 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 oi the staff beginning their duties at the cio5-.e 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.
