narrow spaces being left on either side, that at certain 
points become mere connecting links between the upper 
and low T er portions of the Park. 
The horizon lines of the upper Park, between the New 
Reservoir and 106th street, are bold and sweeping, and 
the slopes have considerable breadth and amplitude in 
almost every direction in which they may be viewed. 
This character is, perhaps, taken altogether, the best 
that can be desired for a park ; and but little alteration 
of surface is, therefore, needed. 
A ravine of considerable extent runs through this sec- 
tion of the Park, in which a small lake ( A ) may readily 
be formed, a view of which is given in Fig. 102; and 
west of this point (A?), where the road meets the dip of 
the two most important hills, a stone bridge is proposed 
to be erected, so that the main circuit-drive may in- 
clude in its course a view T of all the principal features of 
interest in the upper Park. The land, for some distance 
to the north of the boundary line ((7(7), provided by the 
Act of the Legislature, should have been included in 
the original grant, as it commands extensive views that 
are not obtained within the present limits, and consists 
of a series of bold and picturesque rocky bluffs, termi- 
nating abruptly at 110th street, wdiich offer the only 
natural boundary to the Park property. The advisa- 
bility of making this alteration in the line is now evi- 
dent to all who visit the locality ; and the attention of 
the city authorities has been, for some time past, drawn 
to the subject. It is, therefore, quite possible that the 
northern boundary may soon be advanced to 110th 
street. This will add about sixty acres to the area of 
the Park. 
On the easterly side of the upper Park it is proposed 
to plant an American Arboretum (. D ), so that every 
one who wishes to do so may become acquainted with 
the trees and shrubs that will flourish in the open 
air, in the northern and central parts of our country.
