We we're led TO these reflections by observing
the application. at the Cotoetjn squeduct on the
| Chesapeake and Ohio Canal, Of a ne an peculiar
Kind of Cement. patented by I. G CorLE. Of Bal
timore, Md. We were entirely scepticsl of this

had exhausted itself IN vain without suggesting any
Improvement ON the Clements used in our age; bat

We have seen the skeleton Of the wall OF an sque-
duct formed with planks and the space filled with
stones and Cement, and when the planks we're re-
moved, and after the Cement became hard, the

rock composing the structure. We have seen
where the Cement was thrown promiseuousiy on
hard mountain rock which formed the arch Of the
work, and when the siedge or cfowbar vas applied,
he rock invariably broke before the Cemeni would
separate the bond which it formed with the stones.
We perceive from reading the pamphlet OF the
Patentee, containing certificates OF the important
value of this Cement from the highest sources IN
our country, proving that which We had heieiossfe
