the public is in the hemlock forest, where new trails are being 
made in all directions. 
The upper and middle lakes have been cleaned of pond 
weed several times, and all the lakes and swampy grounds 
were treated with copper sulphate or kerosene monthly during 
the summer. 
A great number of rounded boulders found in old stone 
fences and excavations have been used to build a low pro- 
tection-wall along the steep bank of the Bronx River, where 
the driveway approaches near the bank. 
Respectfully submitted, 
F. A. ScHILLING, 
Superintendent of Grounds.
