Zoological Park, and marked it by stone monuments. He also 
did all the engineering work on the Riverside Walk, east of the 
Bronx River, prepared preliminary plans for the boat-house and 
public comfort building, and for an extension of the buildings 
of the Service Yard. 
Beaver Valley Walk.—The completion in 1901 of the trunk 
sewer in Beaver Valley made it possible to construct the long- 
delayed walk leading through the forest in Beaver Valley, from 
Baird Court past the Beaver Pond and Bear Dens to the West 
Farms Entrance. With the consent of the Park Commissioner 
this entire work was performed by day labor under the superin- 
tendence of Mr. Beerbower. At the same time the main walk 
leading from the Buffalo Entrance to the steps near the Buffalo 
House was entirely rebuilt on scientific principles, and connected 
with a branch along the base of the hill to Beaver Valley Walk. 
As a whole, this improvement is of great value and comfort to 
visitors, for it provides a direct route from the entrance to Baird 
Court through a very beautiful portion of the forest. 
Mountain Sheep Walk.—Mr. Beerbower also superintended 
the construction of a first-class walk along the western side of 
the Wild Sheep enclosures, from the Sea Lion Pool to the 
Antelope Walk. 
Bear-Dens.—The most important plans prepared by the En- 
gineer were for the four new Bear-dens. Owing to the very 
irregular nature of the rock and ground, this task was the most 
difficult piece of construction that has yet been performed in the 
Park, and when fully completed it will reflect decided credit upon 
Mr. Beerbower, and also upon Mr. Merkel, who superintended 
the rustic-rock construction. The iron doors and fittings gen- 
erally of the sleeping dens are much superior to those in the first 
series of dens, and the guard rail also is a great improvement 
on the old design. 
DEPARTMENT OF FORESTRY AND GARDENING.—Hermann W. Mer- 
kel, Chief Forester. 
General Maintenance.—As the collections of animals and the 
number of visitors to the Park both increase, the amount of labor 
involved in caring for the Park also increases. Each year calls 
for additional service in the cleaning of the walks and grounds, 
sprinkling walks, the removal of refuse from buildings and yards, 
the hauling of food supplies, and also of live animals. The four
