here.
We were led to these reflections by observing
tho applicatiop, at the Coioctin aqueduct on the
chesapeake and Ohio Canal, of a new and peculiar
Lind of Cement, patented by T. c. CoYLE, OF Bal
,imore. Md. We were entirely scepticai ct tins
hi,b Cement, and believed that human ingenuity
had exhausted itself IN vain without suggesting any
;mproyement on the Clements used in our age; but
in This we were agreeably disappointed by seeing
the spplication of the Cement on the works refer
red to.
This new improvement bids fair to revolutionize
in n orea, measure the mechanic arts with the most
happy results to the world it is simple in Its man.
ufacturc and application, and above all Its cheap
ness, as the materials of which 1t is composed are
to be found every where.
We have seen the skeleton Of the wall Of an aque-
duct formed with planks and the space filled with
stones and Cement, and when the planks were re-
moved, and after the Cement became hard, the
whole walls and bottom Of the ~aqueduct 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

ted with other Cement, but failed, } perfectly tight
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 bind togetser the
rock composing the structure. we nave seen
where the Cement was thrown rromiscuousiy 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 Cement 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 ID
our country, proving that which we had heretofore
believed impracticabie, namely, the cementing OF
stone work under water without the aid OF Golfer
dams; this i. effected in the simplest manner ina
pinable. but the reader must see 1t applied before
he can form any idea of the important result ema-
mating from this Cement to our common country -
It will, in our opinion, supeIsede the necessity OF
dressed stone altogether; it will cement any KIND
of stone into one solid mass, and become as hard
as granite in twenty-four hours; team be MOULDED,
shaped, or formed into any wall, vessel, pier, or
arch which may be required, or, it desired, the
Cement can be made as elastic as India rubber;
4 this may seem strange but it IS Notwithstanding
true, as hundreds have proved throughout the eoun-
try for the last two years. 1t seems to US that Mr..
CoYLs has laid his Cement fairly before the public,
and In doing so, he has sbewn the practical results
off ripe and energetic mind, which could only have
been successful by energy of action and untirlng
zeal. This Cement is admirably adapted to all by
draulic purposes, such as ~fore>bays of mills, water
tanks, water-works, dams, piers, cisterns, granary
floors, spring-houses troughs, rat-proof warehouses,
&c. Sc. Ii will no doubt be found useful for many
other purposes that experience alone will suggest
The subscribers, having purchased Of the Psten-
tee the right for the State of Virginia, avail them
selves of the present opportunity of making known
to the citizens Of Virginia that they are now manu-
featuring the above Cement at the Point OF Rocks,
where any quantity can be furnished to order. we
will also sell the rights for Counties, Cities, Towns,
Districts, Farms or Buildings Applications TO be
! made to the subscribers living at the Point OF
v Rocks, Nd. JOHN HAM,
