the construction of a laboratory building and 
greenhouses.” 
The Secretary presented a communication 
from the Commissioner of Parks, Boroughs 
of Brooklyn and Queens, referring to the 
authorization of an issue of Corporate Stock 
on June 3, 1910, of $25,000, for the construc- 
tion of Plant Houses and $25,000 for con- 
struction of Rooms for Instruction in Botany, 
and calling attention to the fact that “it will 
be extremely difficult to physically separate 
one part of the work from the other, owing 
to the fact that the heating plant provides 
heat for both the Instruction Building and the 
Plant Houses, and there are communications 
between the two. 
Therefore, the Park Commissioner requests 
the Board of Estimate and Apportionment 
“to combine the two appropriations above 
mentioned into a single appropriation.” 
Amendment passed that the resolution of 
June 3, 1910, appropriating $25,000 ‘for the 
construction of rooms for instruction in 
botany,” be amended so as to read “for the 
erection and construction of a laboratory 
building and greenhouses, including equip- 
ment thereof.’’ Passed. 
Amendment also passed that the resolution 
of June 3, 1910, appropriating $25,000 “for 
the construction of plant houses in the 
Botanic Garden and Arboretum,” be amended 
so as to read “for the erection and con- 
struction of a laboratory building and green- 
houses, including equipment thereof.” 
Thus the four separate authorizations were 
“lumped together to obtain economy in con- 
struction.”
