We were led to these reflections by observing
the application, at the Cotoctin aqneduet on me
Cbe,apeake and Ohio Canal, of o new ana pecula'
Lind of Cement, patented by T. G CoYLE, OF Bal

had exhausted itselfin vain without suggesting any
;mnrovement on the Clements used IN our age' Dnt
In this we were agreeably Disappointed BY Seeing

to be found every where.
We bave seen The skeleton Of tbe wall OF an aque-
duct formed with planks and the space nice win

whole walls and bottom of the nqheduct presen'sa

We perceive from reading the pamphlet Of the
Patentee, containing certificates OF tire Important
value Of this Cement from the hlsnest sources 10
our Country. proving that which We bad heretofore
believed impracticable, namely, the cemeniing OF
stone work under water without the aid Of Golfer
dams; this is effected in the simplest manner ma
ENABLE, but the reader must see 1t apPiled before
he can form any idea Of tho important result ema
mating from this Cement TO our common country -
1t will, in our opinion, supefsede the necessary OF
dressed stone altogether; it will cement any hina
of stone into one solid mass, and become as hara
as granite in twenty-four hours; IT can be mouiaeo,
shaped. or formed into any wall, vessel, pier, or
arch which may be required, or, II desired, the
Cement can be made as elastic as India rubber;
this NAV seem strange but it is Notwithstanding
true, as hundreds have proved throughout tne eonn-
try for the last two years. 1t seems TO us that Mt
CoYLE has laid his Cement fairly before The pubic,
and in doing so, he has shewn the practical results
of 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, watcr-works, dams, PIERS, cIsterns, granary
floors, spring-houses troughs, rat-Proot warehouses;
&c. &c. 1t will no doubt be found useful tor many
other purposes that experience alone WIZ suggest
The subscribers, having purchased OF the Paten-
tee the right for the State OF Virginia, avail them
selves of the present opportunity OF making known
10 the citizens of Virginia that they are now manu-
featuring the above Cement al 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
