valley being a very interesting illustration of the behavior of 
a small stream with a large water-shed at and about its 
sources. Considerable areas of the marshy land have already 
been reclaimed by filling, and by the lowering of the dam 
forming the water-fal] at the Lorillard mansion; the general 
plan contemplates a much further reduction in the amount of 
marshy ground, and a further lowering and deepening of the 
river by dredging, in order to take off freshets with greater 
rapidity. A part of this flood plain is occupied by the plan- 
tations of willows and poplars already described, and these 
will be considerably extended, but large areas of meadow 
will be left in their natural condition. 
South of these open meadows, the valley of the river is 
much narrower and is occupied by several acres of charac- 
teristic river woods, containing a considerable variety of native 
trees and shrubs, extending south as far as the long driveway 
bridge near the northern end of the hemlock forest. 
Park Features 
The whole plan of the development of the Garden has 
been designed in such a manner as to include all the features 
of a public park, and it has been carried out in close coépera- 
tion with successive park commissioners and engineers of the 
Borough of the Bronx. The grounds are open to the public 
every day in the year without any charge whatever. An 
elaborate series of driveways provides several miles of Tel- 
ford-Macadam roads, most of which are now constructed, with 
suitable entrances at eight points as follows: 
1. Mosholu Parkway. 2. Bedford Park Avenue. 3. 
Southern Boulevard. 4. Hemlock Forest. 5. Southeastern 
entrance (not yet constructed). 6. Bleecker Street. 7. 
Newell Avenue. 8. Woodlawn Road. 
Paths located so as to lead to all the principal features are 
included in the plan, with an aggregate length of over ten 
miles and approximately one-half of this system has already 
been built. 
All the roads and paths have been located so as to do no
