Temporary Greenhouse. 
At the request of the Director, the President of Columbia 
University has kindly consented to permit the use of the 
greenhouse at the new Columbia University site, 116th Street 
and Amsterdam Avenue, for preserving tender plants during 
the present winter. The plants which have been placed there 
number 148 specimens. All these have been presented, as 
will be seen from the record of gifts appended to this report. 
Seeds of a large number of others have been planted in this 
greenhouse and space has been provided by constructing 
some new shelving to plant many more; seeds are being con- 
tinually received from various sources, and it will be possible 
to sow several hundred species in the late winter and early 
spring. 
Care of the Grounds. 
From time to time during the year, dead and unsightly 
trees and shrubs, and trees of inferior appearance which in- 
terfered with the good ones, have been taken down, and 
many others have been pruned of dead branches. The tract 
is so liberally provided with trees that this work will need to 
goon, to a greater or less extent, every year. Fallen branches 
have also been cleared away, and loose stones have been re- 
moved from much of the site. 
The hay of the tract was cut in July and August by George 
Hudson, of Bronxdale, on shares, he taking one-half and 
stacking one-half on the grounds. The part stacked has 
since been sold for $191.82, and this sum deposited with the 
Treasurer. 
Williamsbridge and Bronx Park Sewer. 
The Commissioner of Street Improvements of the 23d and 
24th wards asked permission from the Board of Managers, 
in the spring, to construct a sewer across the northern part of 
the Garden, from Newell Avenue to a point on the N. Y. and 
Harlem Railway opposite the Mosholu Parkway, together 
with a branch extending to the eastern boundary of the Gar- 
den, the object being to connect the unfinished sewer system
