tion was established on the north side of conservatory 
range I, the plants purchased by an appropriation from the 
income of the John Innes Kane Fund.* Early in the 
spring, a considerable number of trees were planted near 
and along the western bank of the Bronx River north of 
the Linnaean bridge, and the banks at that bridge were 
planted with several kinds of willows. In the autumn, a 
commencement was made to extend the deciduous arbore- 
tum southward on the additional land by planting several 
kinds of poplars east of the long lake near the Bronx 
Boulevard, and ground was prepared and some preliminary 
planting accomplished near the iris garden at the south- 
western corner of the grounds. Many plants were moved 
from the nurseries, both in the spring and in the autumn, 
to permanent places in various parts of the grounds. 
Substantial additions have been made to the greenhouse 
collections, the most noteworthy being several hundred 
cactuses and other plants collected by Dr. J. N. Rose 
during the year in Brazil and Argentina, in continuation 
of our cooperation in the cactus investigation with the 
Carnegie Institution of Washington; a fine collection of 
Brazilian orchids presented to the Garden by Dr. Y. de 
Oliveira Botelho, Brazilian Delegate to the Second Pan- 
American Scientific Congress; and a collection of native 
ferns of Porto Rico obtained during our expedition to 
that island in the spring. 
A detailed account of the composition of the collections 
and of gardening work will be found in the report of the 
Head Gardener hereto appended.
