LANDSCAPE GARDENING. 
It is not intended to be arranged formally, but so that 
it may present all the most beautiful features of lawn 
and woodland landscape, preserving, at the same time, 
the natural order of families, as far as practicable. In 
the event of the extension of the Park to 110th street 
being made, the space occupied by the Arboretum 
might be considerably enlarged. 
The lower Park, between 59th street, and the New 
Reservoir, is far more heterogeneous in its character, 
and requires a much more varied treatment. Its most 
prominent and characteristic feature is the long, rocky 
hill-side immediately south of the Old Reservoir ; and 
this has been accepted as the central point of landscape 
attraction, to which the other ornamental arrangements 
of the plan are to be made more or less subservient. A 
skating-pond, or lake, of varied outline, and containing 
about fifteen acres, surrounds a considerable portion of 
the base of this hill, and, in a measure, separates it from 
the rest of the lower Park. Expanses of lawn are pre- 
pared on the table-land forming the summit of the hill, 
and the side is converted into a ramble, with a labyrin- 
thine arrangement of foot-paths, leading the visitor 
among groves and shrubbery, rivulets, rocks, and glens, 
to the prominent points of view that are obtained in this 
part of the grounds. 
A cavernous passage formed by large, overhanging 
rocks has been discovered, and excavated during the 
summer, and is an interesting incident heightening the 
naturally picturesque character of the ramble. 
The Promenade (E) is the feature next in importance in 
the lower Park. It consists of a broad level walk be- 
tween double rows of elms. The boundaries are to be 
on all sides irregularly planted, so that its formality will 
scarcely be perceived, except within itself. Its northern 
extremity is finished architecturally, and, as suggested 
by the original outline of the surface, is elevated about 
twenty feet above the ground immediately to the north,
