house, and about four thousand inhabitants. Many of the houses 
are built of blue limestone, and of brick. The town contains se¬ 
veral mills and manufactories; and amongst others, a nail factory, 
in which the nails are made with a machine, as in Birmingham. 
They also manufacture rifle-guns, which are very long and heavy. 
On the right bank of the Genesee river, the houses are not so nu¬ 
merous as on the left, and there are yet many frame, and eyen 
some log-houses: in the place where, probably in a short time, 
handsome wharves will be built, there may yet be seen stumps 
of trees—a truly interesting sight to those who observe the pro¬ 
gress of this country. The basements of the houses are generally 
built of rough sand-stone; their corners, doors, and windows, of 
a kind of white marble-like sand-stone, and the rest of brick. 
The white sand-stone is procured in the neighbourhood, and is 
cut into slabs at a saw-mill on the Genesee river. I saw three of 
these blocks sawed; and in one frame I observed no less than five 
saws. Several hundred yards below the bridge the Genesee 
river is about two hundred yards wide, and has a fall of ninety- 
five feet, which at present, however, did not appear to much ad¬ 
vantage, Above the falls is a race which conducts the water to 
several mills, and it again flows into the river below the falls, 
where it forms three beautiful cascades, which reminded me of 
the Villa di Macen, at Tivoli. 
At Rochester the Erie canal is carried over the Genesee river 
by a stone aqueduct bridge, and resembles that of the Bridge- 
water canal at Manchester, in England. This aqueduct, which 
is about one thousand yards above the falls, rests upon a base of 
slate rock, and is seven hundred and eighty feet long. A work 
which has been lately published, called the ^ Northern Tour, 5? 
gives the following description of it: -“The aqueduct consists of 
eleven broad arches, built in the form of circular segments, the 
tops of which are raised eleven feet above the level of the arches, 
and fifteen feet above that of the water in the river. The two ex¬ 
terior arches have an extent of forty feet each, and beneath them 
are the streams which turn the mills; the other nine each fifty 
feet wide, &c.” Upon one of its sides is a tow-path secured by 
iron railings. The whole is a solid work, and does much credit 
to its architect, Benjamin Wright. 
We left Rochester at nine o ? clock, on board the canal packet- 
boat Ohio, Captain Storch. The canal, between Lockport and 
Rochester, runs a distance of sixty-three miles, through a tolera¬ 
bly level country, and north of the Rochester ridge. This ridge 
consists of a series of rocks, which form the chain of the moun¬ 
tains which commences north of Lake Erie, stretches eastward 
to the Niagara river, confines it, and forms its falls, then con¬ 
tinues its course, and forms the different falls which are north of
