the iris beds. A bank 10 feet wide on the eastern side of 
the white pine plantation was graded and sodded for a 
distance of 432 feet. The old lane in the red pine collec- 
tion has been filled in and is now ready for topsoil. The 
southern bank of the rose garden was also graded and 
sodded. 
Outside contractors looking for a convenient place to 
dispose of soil from excavations carted about 1,000 cubic 
yards into the Garden at their own expense. This con- 
tained 250 yards of topsoil, which we used for the new 
iris and fern beds. On the eastern side of the roadway 
near the Linnaean Bridge 50 yards were used for grading 
and 700 yards were placed along the railroad fence north 
of the Woodlawn Road entrance. 
About 500 cubic yards of stone were blasted and re- 
moved from the quarry near the museum building and 
used to construct paths in the iris garden and around the 
cherry garden shelter. 
Drainage 
It was necessary to build three catch-basins in order to 
drain the iris garden, for which we used 74 feet of 4-inch 
tile pipe, 12 feet of 3-inch tile pipe and 106 feet of 2-inch 
porous pipe. We rebuilt about too feet of the old culvert 
south of the herbaceous grounds. At the southern end of 
the serpentine road, 50 feet of 12-inch tile pipe were re- 
moved and a culvert 18 inches high, 24 inches wide and 
50 feet long was installed. 
Water Supply 
In order to increase the water pressure in the mansion, 
750 feet of a 4-inch water main, with one gate and a branch 
tee, were laid along the unfinished road from the school 
garden to the rose garden to make a connection with the 
4-inch main that runs to the front of the mansion. To 
bring about this connection into the mansion 4o feet of 
2-inch pipe with two 1}4 inch taps were employed. This 
connection is sufficient to raise water 70 feet from the
