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, is a remarkable relic of a type 

 of vegetation which was common and widely distributed in 

 tertiary geologic time, but is now restricted to eastern tem- 

 perate Asia in this one species, Gi7ikgo 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 (Abies 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 located 

 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.
