is skylighted and has a cemented floor ; its contiguity to the other laboratories 

 is a great advantage. A constant temperature room in the basement has been 

 found to furnish a satisfactory thermographic curve, although it has not yet 

 been used in research work. 



A compartment in the propagating houses, comprising about a thousand feet 

 of floor space, is equipped for experimental work in connection with the labora- 

 tories, and ample space is afforded in the plantations for the same purpose. 



It is to be seen that the Garden affords opportunity for research in all of the 

 broader questions of botany, inclusive of climatological influences, acclimati- 

 zation, history of species, development of races and varieties, hybridization and 

 horticultural practice, development, general morphology, embryology, physiology 

 and environmental relationships in general, and natural affinities of species and 

 groups. 



The presence of a number of investigators in different phases of the subject 

 has a most stimulating effect upon the individual student, and the mutual inter- 

 change of views does much to counteract the tendency to over-specialization. The 

 number of registered students using the laboratories, library, or herbarium during 

 the past year was twenty-eight, and most of them were graduates of colleges and 

 universities. Botanists from other institutions using the facilities of the insti- 

 tution, for periods from a day to over a month, numbered more than a score. 



An especially profitable feature exists in the weekly conventions, at which 

 the worker gives an account of his own results, a review of some recent book 

 or article, or a visiting botanist gives an address upon some subject of general 

 interest. Subjects have been recently presented as follows :

 Underwood.

The following outline shows the special subjects in which investigations may 

 be carried on, together with the name of the person under whose guidance the 

 work may be done. It is to be said, however, that almost any problem in botany 

 may be taken up by trained botanists of sufficient experience who may resort to
