We are constrained to say, however, that the principal 
difficulty in carrying out even this limited plan is the in- 
sufficient surface suitable for such an exhibition. This is 
nowhere more manifestly true than as regards the rumi- 
nants, for within the limits of Long Crouch Woods itself 
it would be entirely impossible to display in any pleasing 
or profitable manner those largest forms among our quad- 
rupeds which excite, perhaps, greater interest than any 
other, — the bison, moose, elk, caribou, deer ; for this pur- 
pose it is absolutely essential .that more ground be had, at 
least so far as a range is concerned. And this we hope 
the Commissioners will grant, whenever needed, — perhaps 
in the ground which has been set apart as a deer-park, in 
which it would be quite possible, by lines of wire fence 
practically invisible, to separate such bands as could not be 
brought into a common enclosure. 
2. What has been said thus far relates principally to the 
terrestrial animals. Another mode of exhibition for the 
freer-moving, aerial creatures may be advantageously pur- 
sued. Thus it might be possible in a series of outdoor 
aviaries, sufficiently large to enclose good-sized trees, to 
bring together at their proper periods the characteristic 
summer or winter birds, so that one might see for himself 
what was the avifauna of New England at any given time. 
In others might be placed, as a permanent exhibition, such 
of our native breeding birds as would bear association, 
where they might find room enough*, and suitable places, for 
all purposes of nesting and bringing up their young. The 
headlong flight of some birds might prevent their exhibi- 
tion here. Similar aviaries for the exhibition of birds 
found in our North Temperate zone west of New England 
should be placed side by side with those of New England 
itself; while the exhibition of foreignbirds for comparative 
purposes, limited in the same way as those of the less
