Regulating and Grading 
This work has been accomplished in many parts of the 
Garden. In front of conservatory range 2, we removed 
about 2,800 yards of earth which was used to grade along 
the eastern boundary fence, for a path around the western 
side of this range, for filling the bayou south of the boulder 
bridge and for filling at the northern side of the long bridge. 
The bayou at the sewer syphon was filled in to the grade of 
the north meadows, about 125 yards of earth being here 
used. About 150 yards of top-soil were used to fill in and 
grade the ground west of the syphon. We graded the north 
meadows with about 150 yards of top-soil. Both sides of 
the upper bridge were graded with 75 yards of top-soil. 
The sod border was lowered along the edges of the roads 
at the west end of the long bridge, the north end of the lake 
bridge, the west side of the museum building, and on the 
truck road from 200th street entrance to the elevated 
railway approach. 
The lowlands north of the woodlawn road approach 
were filled in with 2,400 yards of earth by contractors 
working in the vicinity of the Garden who wanted a con- 
venient place to dispose of it. 
About 3,000 yards of earth, goo yards of top-soil, and 350 
yards of stone were removed. The stone was used to 
complete the path through the pinetum and paths on the 
eastern side of the river. This stone was also used for 
liners of paths north of the sewer syphon and for paths 
around conservatory range 2 and power house 2. 
Drainage 
A catch-basin was built on the western driveway to dispose 
of the surface water north of the Mosholu Parkway ap- 
proach. To do this, 36 feet of 4-inch drain-pipe were used. 
We extended the surface drain north of the long bridge, 
using 38 feet of 6-inch pipe, and the drain pipe at the syphon, 
using 57 feet of 12-inch pipe. In connecting power house 
2 with the surface drain, we used 110 feet of 12-inch pipe.
