THE BROOKLYN BOTANIC GARDEN 



341 



bush Avenue, opens northward through an esphinade to the museum 

 building, and southward and eastward to the public conservatories and 

 the laboratory and administration building. In the northeast corner of 

 the garden is a lake of about three acres in area, and the adopted plans 

 provide for a small stream leading southward through the grounds 

 from the lake. The lake and stream together will afford excellent op- 

 portunity for aquatic planting.

 The northeast house (at the left) connects with the Physiological Laboratory. The 

 division of the northeast wing into four houses is made with reference to their use 

 for class work and for investigations. 



The location of the garden is of considerable physiographic in- 

 terest, for it is situated on the extreme southern margin of the terminal 

 moraine deposited by the continental ice-sheet. As is well known, a 

 portion of this moraine forms the so-called " backbone " of Long Is- 

 land, and two or three morainal knolls give relief to the northwestern 

 and the eastern edges of the grounds. The remainder of the garden is 

 on the area of the overwash plain lying south of the moraine, but the 

 surface soil is no longer of geological significance in this connection, as 

 there have been considerable grading and top-soiling in connection 

 with park operations. A few large glacial boulders remain in place and 

 exposed at the surface. 



The laboratory building, wdien completed, will be a one-story and 

 basement structure of bricik, faced with concrete, about 240 feet long, and 

 50 feet wide, with a maximum elevation of about 60 feet (Kg. 2). At 

 suitable places on the exterior will be placed the names of noted botan- 

 ists of the past. For this purpose there are twenty-two spaces on the 

 frieze for names of greatest prominence, each space to contain only one 

 name. Under each window is a panel to contain three names. The 

 choice of names was determined by a vote of contemporary American 

 botanists.
