We were led to these reflections by observing
the application, at the Cotoctin aaueauct on tie
Chesapeake and Ohio Canal, of a new and peculiar
kind Of Cement, patented 10y T.. c CoYLE, OF Bal.
umoFe, Md. We were entitely ~sceptcal Of this
high Cement, and believed that human ingenuity
had exhausted uselfm vain without suggesting any
improvement on the Clements used in our age; but
IN tins we wete agieeably disappointed by seeing
the application Of the Cement on the works refer.
ed TO.
This new improvement bids fair to revolntionise
IA a grea' measure the mechanic arts with the most
happy results to the world il is simple in It's man
uiacture and application, and above all it's chean-
ness, as the materials of which it is composed are
to be found every where.
We have seen the skeleton Of the wall Of an aoue.
duct formed with planks and the space filled with
stones and Cement, aud when the planks were re-
moved, and after the Cement became hard, the
whole walls and bottom Of the aqaeduct presented
the appearance Of a dark marble basin, perfectly
clear and free from pores, with "A beautiful high
polish, as tight as a bottle and as hard as IRON
thus making the work (Which had been cons,ruc.
ted with other Cement, but failed, } perfectly .iglt
and impervious to water; besides, by this simple
process, the company have been saved the vast ex.
pense OF rebuilding, which soon must have taken
place, as the pressure OF the water had washed the
old Cement away and left the pile of stone a mere
skeleton, without any thing to bud together the
rock composing the structure. We have seen
whore the Cement was thrown promiscuously on
hard mountain rock which formed the arch Of the
work, and when the sledge or crowbar was applied
the rock invariably broke before the Cemcn, would
separate the bond which ii formed with the stones.
We perceive from reading the pam ehlct of the
Patentee, containing certificates of tie important
value of this Cement from the highest sources 10
our country, proving that which we had heretofore
believed impracticable, namely, the cementine of
stone work under water without the aid Of Golfer
dams; this Is effected in the simplest manner ima-
ginable, but the reader must see il applied before
he can form any idea of the important result ema-
mating from this Cement TO our common country -
Ii will, in our opinion. supo,sede the necessity of
dressed stone altogether; it will cement any kind
OF stone into one solid mass, and become as hard
as granite in twsnty-four hours; it can be moulded.
shaped, or formed into any wall, vessel, pier. or
arch which may be required, or, If desired, the
Cement can be made as elastic as India rubber ;
this may seem strange but it is notwithstanding
true, as hundreds have proved throughout the eaun-
try for the last two years. II seems to VA that Mr..
CoYLE has laid his Cement fairly before the public,
and IN doing so, he has shewn the practical results
OF a ripe and energetic mind, which could only have
been successful 10y energy Of action and untiring
zeal. Tbs Cement is admirably adapted TO all hy-
draulic purposes, such as fore.bays Of mills, water.
tanks, water-works, dams, piers, cisterns. granary
floors, spTing-houscs troughs, ~rat-proof warehouses,
&c. &c. 1t will no doubt be found useful for many
other purposes that experience alone will suggest.

selves of the present opportunity Of making known
to the citizens of Virginia that they are now manu-.

where any quantity can be furnished 10 order. We
will also sell the rights for Counties, Cities, Towns.
