lar. It has 11 churches, 2 banks, a museum, an
arcade, an athcneum, and several literary institu-
tions, 2 daily and several weekly newspapers.
Within the limits of the village, for such is the ti-
tle of this flourishing city, are 13 large flour mills,
built of stone, which grind 342,000 barrels of flour
annually. Some of these mills are on a scale of
magnitude not equalled elsewhere in the world.
Ono of them covers more than 4 acres, and all ara
considered unrivalled in the perfection of ther ma-
chinery. Here are also cotton and woolen manu-
factories, and saw-mills which turn out 9,000,000,
feet of lumber in a year. The Genesee falls are
in the northern part of the town, and the water
power which tbe river affords here, is immense.
There are three bridges across the Genesee at
this place ; the canal aqueduct deserves particu-
lar notice. The canal strikes the river in the S.
part of Rochester, and after following the eastern
bank for half a mile, crosses the river in the cen-
tre of the town in an aquaduct built upon 11 arch-
es of hewn stone 804 feet in length ; the structure
is no less worthy of admiration for its strength than
its architectural beauty. From the observatory
at the summit ofthe arcade may be seen in a. clear
day the waters of Lake Ontario like a strip of
blue cloud on the verge of the horizon. Roches-

This county takes its name from the celebrated
natural bridge which is situated within its limits.
This remarkable work of nature has been formed bv
the bursting of the waters of a stream called Ce-
dar creek through a wall of rock more than 200
feet in height. The bridge is 60 feet in width
and the sides for the great part of their height are
nearly perpendicular. A road passes over the
top. The scenery it affords is exceedingly grand

Rocky Mountains, an immense chain in the
western part of North America which may be re-
garded as a continuation of the Cordilleras of
Mexico. They extend Northwesterly nearly to
the Frozen Ocean, and form the ridge which se-
parates the waters of the great basin of the Mis-
sissippi from those which fall into the Pacific
In extent, in elevation, and in breadth, the
Rocky mountains far exceed the Alleghanies of
the eastern states. Their mean breadth is 200
miles, and where broadest, 300. Their height
must be very great, since, when first seen by cap-
tain Lewis, they were at least 150 miles distant
On a nearer approach, the sublimity of the pros-
pect is increased, by the appearance of range rising
behind range, each yielding in height to its suc-
cessor, till the most distant is mingled with the
clouds. In this lofty region the ranges are cov-
ered with snow in the middle of June. From this
last circumstance,these mountains have been some-
times denominated the Shining mountains—an
appellation much more appropriate than that of the
Rocky or Stony mountains, a property possessed by
all mountains, but peculiar to none. The longi-
tudinal extent of this great chain is immense,
running as far N. AV. as 60 N. lat., and perhaps
to the Frozen Ocean itself. The snows and foun-
tains of this enormous range, from the 38th to the
48th degree of northern latitude, feed, with never-
failing supplies, the Missouri and its power-
ful auxiliary streams.
A great number of lateral ranges project to the
S. E., E., and N. E. of the main range. Where
the Missouri enters the plains, is the most east-
ern projection ; and from where the Yellow Stone
leaves the snowy range, there is a range, run-
ning more than 200 miles south-east,which is inter-
sected by the Bighorn river. As these mountains
have not yet been explored by the eye of geolo-
gical science, it is impossible to say any thing
respecting their component parts ; but, from any
thing that we can learn from Pike and Clarke,
they seem to be chiefly granitic. No volcanoes
have yet been discovered amongst them; but
strange unusual noises were heard from the moun-
tains, by the American party, when stationed
above the falls of the Missouri. These sounds
seemed to come from the northwest. Since out
arrival at the falls, says tbe narrative, we have
repeatedly heard a strange noise coming from the
mountains, a little to the north of west. It ia
heard at different periods of the day and night:
sometimes when the air is perfectly still and un-
clouded, and consists of one stroke only, or of five
or six discharges in quick succession. . It is loud,
