Power House. Steam for heating the conservatories is 
supplied from the power house, located near the New York 
Central Railroad just south of the 200th street entrance and 
connected with the conservatories by a subway about six 
hundred feet long containing the steam mains; five boilers 
are installed at the power house and supply steam not only to 
the conservatories, but also to the museum building through 
another subway about twelve hundred feet in length. 
2. The Botanical Museum 
The Museum Building has a frontage of 312 feet, and in 
so far as now constructed, a depth of about go feet; the plan 
of this building contemplates its future extension toward the 
rear, so as to form a quadrangle enclosing a court. Three 
floors are devoted to public exhibits, while the upper floor 
contains study rooms, the library, laboratories and herbarium, 
which may be used and consulted by permission. The archi- 
tectural style of the building is Italian Renaissance. The 
walls are of light-colored brick and the trimmings of terra- 
cotta. It has a steel frame and concrete floors. 
The building is approached by two straight driveways and 
accompanying sidewalks leading from the main park driveway 
near the New York Central Railroad station; this front ap- 
proach to the building is ornamented by a bronze fountain 
executed by the sculptor Carl E. Tefft, and by terra-cotta 
fountains and marble seats designed by R. W. Gibson, the 
architect of the building. The vista lines are formed by 
four parallel rows of trees. 
The public collections in this building are:
