TO PROFESSOR SILLIMAN. 
Sir, 
_ 1 uave 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-Yor 
T enesee river falls into lake Ontario, on its South 
coast, sthgit 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-

e bridge. It is first seen from a small elevation, to 
cross among lofty and dense foliage, a gulf 200 feet deep, 
and wide, whose mural sides are curiously — 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
