14 MISSOURI BOTANICAL GARDEN. 
including work in the vegetable house —somewhat more 
than one-eighth each, and the walks and the collections of 
woody plants a little over one-twelfth each. The sea- 
sonal distribution of hours of labor respectively on plant 
houses and frames, and on beds, ponds and rockeries, for 
1902, with corresponding averages for the preceding five 
years, is graphically presented in diagram B. 
The border of trees and shrubbery of the recently 
graded tract at the southern end of the Garden again suf- 
fered to an unexpected degree last winter, but the lost trees 
have been replaced, and it is hoped that in the coming sea- 
son the planting of the North American synopsis may be 
completed in large part in this tract. Though gravel 
walks will ultimately be carried through this addition to 
the grounds, it is the intention for the present to maintain 
in it turf walks only, and a fairly good bluegrass sod has 
already been established on much of the tract. 
Toward the end of last winter a fire originated in one 
of the temporary flue-heated plant-houses, damaging the 
house and destroying or injuring its contents, and in the 
early autumn, glass, somewhat in excess of 1,100 square 
feet in area, was broken by hail. The loss in both cases 
was fortunately light. 
Among the additions and improvements made during the 
season should be noted the provision of a series of plant- 
houses of modern design and good construction, for the 
growth of plants needed for display in the houses which 
are open to the public, — the results of which are already 
very noticeable in the latter, — and for the propagation of 
bedding plants. ! 
During the year, 128 species or varieties of plants were 
dropped from cultivation, and 1,712 were added, making a 
net gain of 1,584 for the year,* the total number recorded
