132 Treubia Vol. Ill, 2. 



Plan No. 1 gives a general view of the present site of the Laboratory 

 for Marine Investigations. 



The main ^building, the Laboratory proper (1, Plan No. 1) faces the 

 North, i.e., the sea, and to the South of it lies the Aquarium (2, Plan No. 1) 

 and a rough v^orkshop (3, Plan No. 1), roofed over but open on the sides. 



The annexes 4, 5, 6 and 7, consist of:- a dark room; a store room 

 for glass work and reagents; a store for fishing nets and implements and 

 suchlike articles; a bathroom and closet, respectively. 



The figure 8 (Plan No. 1) indicates the dwellings for those natives of 

 the Laboratory staff who must live on the spot ; these are made mosquito-proof. 



The various buildings are connected with one another by means of 

 roofed-over paths (on account of the heavy tropical sun and showers). 



On the North Westerly portion of the site a pond (9, Plan No. 1) has 

 been made which communicates to the South with a swamp (10, Plan No. 1). 



The whole site is enclosed in a wire fence with angle iron posts set 

 in cement footings. 



This fence has four entrances, of which the Northerly, Easterly and 

 Westerly are usually closed; the Southerly being the main entrance. 



Just inside the Southerly fence, a hedge of Lantana camara L. is 

 growing; a similar hedge, but of Pliichea indica (LESS.) runs along the 

 Westerly fence. 



An elevated reservoir, for water from the town main, is situated just 

 South of the Westerly extremity of the rough workshop (3, Plan No. 1), 

 but is not yet indicated on Plan No. \. 



The artesian water from the town water main, is lifted into this reser- 

 voir by an electrically driven centrifugal pump, whence it is distributed 

 through reticulation pipes to the various buildings, and is also used, during 

 the dry season, to water the lawns. 



That portion of the site not built upon is set aside as a garden, in 

 which as great a number as possible of East Indian 'beach and coast 

 plants will be collected; of every species a pair of specimens. 



It is not so much the object to try to grow the plants under circum- 

 stances which differ as little as possible from their natural environment, 

 as to bring together a collection of living plants for the preliminary 

 instruction of those investigators who visit the Laboratory for Marine In- 

 vestigations, and who wish to study the beach and coast flora of the 

 East Indies. 



Already a number of living plants have been collected, principally from 

 the coral islands of the Bay of Batavia, and have been transferred to the 

 Laboratory garden. 



In fact, there are already growing along the sides of the pond and 

 swamp (9 and 10, Plan No. 1) which contain brackish water ^), and also 



') On the 4th of Mav 1922 the salinitv of this water amounted to 23,6 7oo.
