For the prosecution of such experimental work the 

 Garden does not now possess adequate quarters; addi- 

 tional laboratory space would 

 be required. The fundamental 



requisite of laboratory rooms is abundant light, and 

 preferably light from the north. A laboratory for experi- 

 mental botany requires also greenhouse facilities imme- 

 diately at hand. The original architectural plan of the 

 museum building included the construction of a wing 

 extending from each end of the present building toward 

 the north and the completion of a quadrangular court 

 by means of a fourth structure extending east and west 

 and connecting the north ends of the two wings. This 

 plan contemplated the placing of all the scientific work 

 under one roof. I believe that there are serious objections 

 to the inclusion in such a building of the quarters for 

 experimental work. In the first place, all the rooms facing 

 the court would have inadequate lighting; the east and 

 west exposures of the two wings would not be the best; 

 and the structure on the north side of the court would 

 offer its best facilities on the north side only. In the 

 second place, greenhouses would have to be built on the 

 roof of the building, and, although this would be possible, 

 it is doubtful whether it would be the best location during 

 the rigors of our winters. In the third place, both the 

 herbarium and the library are even now hampered by 

 reason of inadequate space, and need, moreover, addi- 

 tional provision for continual future growth; and the 

 proposed extension of the museum can only be made 

 possible by enlarged quarters. It may, therefore, well 

 be considered whether it would not be wise to have the 

 wider vision and reserve the museum building for her- 

 barium, library and museum, together with the w r orking- 

 rooms required for their maintenance, and for the admin- 

 istrative offices. In such case an additional building
