not to so great an extent as in the region next to be described. Among the 
Mammalia, we find the Northern Lynx, the Deer Mouse and Porcupine; while 
all the lakes in the interior of this district, which empty into the Lake Ontario, 
formerly abounded with Salmon, which found their way from the sea through 
the Gulf and River St. Lawrence. In its southern portions it is similarly con¬ 
nected with the basin of the Mississippi, and the intermediate regions are watered 
by the streams which empty into the Delaware and Chesapeake. 
2. The Northern District comprises, as its name imports, the northern portion 
of the State, which forms an irregular truncated triangle, bounded on its western 
side by Lake Ontario and the River St. Lawrence, on its eastern side by Lake 
Champlain and Lake George, and lying north of the Mohawk valley. This 
district, in its southern and southeastern portions, rises into numerous conical 
peaks and short ranges, attaining in some places an elevation of more than five 
thousand feet. Towards Lakes Champlain and George, these subside suddenly 
to the level of those sheets of water. To the north and northwest, this descends 
by a gradual and almost imperceptible slope towards the River St. Lawrence. 
This slope is watered by the Oswegatchie, the Moose and Black rivers, the Ra- 
quet and Grass and St. Regis rivers, all arising from numerous lakes embosomed 
in the mountainous regions of its southern parts. Lake Champlain, a part of its 
eastern boundary, extends north and south one hundred and forty miles, is twelve 
miles wide in its broadest part, and discharges its water through the Sorel river 
into the St. Lawrence. Into the southern part of this lake is also poured the wa¬ 
ters of Lake George or Horicon, thirty-seven miles long, and varying from one 
to seven miles in breadth. The cluster of mountains in its southeastern portions 
may be considered as-an offset from the great Appalachian system, which, de¬ 
scending through the States of Maine, New-Hampshire and Vermont, passes 
southwesterly between the Western and Hudson river districts, and is continued 
under the name of the Allegany range of mountains. In this region too we find the 
Sacondaga, Cedar, Jessup, and other tributaries of the Hudson, within a short 
distance of those which pour into the St. Lawrence. This mountainous region 
comprises the counties of Essex, Hamilton, Herkimer and Warren, and the 
southern part of the counties of Clinton, Franklin and St. Lawrence, and has 
been estimated to contain an area of about six thousand square miles. Its zoolo¬ 
gical character is strongly impressed by the features just alluded to. The chief 
growth of trees in this district are the Spruce, Tine, Larch, Balsam, Fir and
