of which may be found on the southern portion of the 
westerly ridge of the herbaceous grounds. This interesting 
tree, with its fan-shaped leaves, isa remarkable relic of a type 
of vegetation which was commonand widely distributed in 
tertiary geologic time, but is now restricted to eastern tem- 
perate Asia in this one species, Ginkgo biloba. 
PLANTATIONS OF YOUNG CONIFERS 
The young white pine forest, established in the spring of 
1916 on the rocky hill north of the iris garden, in coopera- 
tion with the State Conservation Commission through the 
interest of Dr. Walter B. James and the Honorable George 
D. Pratt, has continued to develop satisfactorily, and is of 
great interest as a demonstration of forest establishment. 
It has been carefully protected from fire by keeping the 
grass cut short in the autumn, and each young pine has 
been mulched with a small amount of leaf mold. 
Through the further interest of the State Conservation 
Commission and of Dr. James, a new plantation of the red 
pine (Pinus resinosa) was made in the spring of 1918 on 
the rocky ridge opposite Fordham Hospital, nearly 2,000 
four-year-old transplants being furnished by the Commis- 
sion at a nominal cost. It happened that planting con- 
ditions were so good that nearly every pine grew, and this 
plantation has also been of exceptional interest. 
A small plantation of the white fir (.fbies concolor), a 
native of the west, has also been installed nearby, adjoining 
the beds of cannas in the horticultural collections. 
The Victory Grove of 150 Douglas spruces (Pseudotsuga 
mucronata), also natives of western America, is locate 
near the beds of gladioli in the same area. The trees were 
already about five feet high when planted in the spring of 
1919 as war memorials.
