Nursertes. In addition to the nursery grounds planted in 
1896 and 1897, additional space of about one acre was pre- 
pared in the spring, near the southern corner of the tract, 
and partly occupied by shrubs and trees transplanted from 
the older nurseries, and partly by a very valuable collection 
of cuttings and seedlings from Siberia, received through the 
United States Department of Agriculture. The space set 
free in the older plantations was used for new material from 
various sources. 
In the autumn nearly all the trees and shrubs set in the 
nurseries during 1896 and 1897, were transplanted to the 
Fruticetum, Arboretum and Borders, so that there is enough 
nursery ground already broken up for next spring’s planting 
of seeds and seedlings. 
Borders. The border screens have now been planted 
around the entire tract, except along the extreme southeastern 
side occupied by the nurseries and along the line where the 
Garden Reservation meets the other land of the park to the 
south. Considerable rearrangement of the older plantations 
along the railroad has been made by withdrawal and substi- 
tution; these borders will serve as reserve nurseries for many 
years. 
Temporary Greenhouse. The use of the greenhouse on 
the Columbia University grounds at Morningside Heights, 
kindly granted by the President in 1896, has been continued, 
and has proved most important for preserving the valuable 
tender plants which have been donated by many friends, and 
for the growing of seeds from various sources. A list of 
species here stored is appended. 
Record of Species under Cultivation. The Card Cata- 
logue has been kept posted up as material has come to hand 
and a complete record of all plants grown is provided. In 
addition to this an herbarium specimen has been made of all 
plants which have flowered on the grounds and these have 
been brought together by families into a special herbarium, 
which is serving a valuable purpose in answering questions 
relative to species.
