Arr. VII. Remarks on the environs of Carthage Bridge, 
near the mouth of the Genesee River; by Dr. Joun I. Bies- 
By, of the medical Staff of the British army in Canada. 
TO PROFESSOR SILLIMAN. 
Sir, 
I wave the honor of addressing to you’ a few observa- 
tions, on the environs of the justly celebrated bridge at Car- 
thage, on the Genesee river, in the State of New-York. 
The Genesee river falls into lake Ontario, on its South 
coast, about ninety miles from Fort Niagara. At its mouth, 
on the left sloping grassy bank, stands the village of Char- 
lottestown, a small, and irregular cluster, of dwellings, stores 
and taverns. The river is here perhaps two hundred yards 
broad, but it varies much during its course. The banks soon 
rise to the height of from 80, to 140 feet, and continue to as- 
cend to the first falls, five miles from the lake, where they 
are 196 feet high. ‘They are always steep and covered with 
trees, especially cedar and hemlock, growing among ferru~ 
ginous brown sandstone in debris, and shivered horizontal 
layers. 
The Steam-boat Ontario, from Lewistown, stops at “ Han- 
ford’s Landing,” a mile below the first falls ; where two 
storage houses and a small wharf stand on a narrow slip of 
ground, under the high and woody steeps.-_-A. winding road 
leads up the precipice. 
On the summit of this road we are surprised to find our- 
selves at once, in a populous district, among cultivated 
grounds, and handsome stores and houses, distributed ac- 
cording to the interest of the proprietors. 
Advancing a mile, along the river, on the road to Roches- 
ter, through fields and woods, we arrive in view of Car- 
thage bridge. Itis first seen from a small elevation, to 
cross among lofty and dense foliage, a gulf 200 feet deep, 
and 340 wide, whose mural sides are curiously striped by 
white and red strata. At the near end, a tasteful lodge is 
erected for the accommodation of the toll-gatherer. 
It consists of a single arch, 342 feet in width, a segment 
of a circle, I believe. ‘The whole edifice is of wood, and 
is 740 fect long. Its breadth allows of neatly railed paths,
