man, ia the creature, il will be also the instrument
If the peoples will. Individual enterprise, there
fore. must and can accomplish In America, what
,norarchical patronage has done in Europe. The
vas, discoveries that are s~pringing up daily in eve

~ mechanical arts, forbid us to despair that our
beloved country will be other than foremost in the
race of scientific pursuits; to accomplish which,
does it not behoove every lover OF his country and
its system of Government, to show to the world
that man constitutes a slate, and what kings, Prin.
ees. and mobiles can do in Europe, men can do
here.
!. the application, at the Cotoctin ~aqueduct on the
chesapeake and Ohio Canal, of q new and peculiar
Lind OF Cement, patented by I. c CoYLE, OF Bal
,imore, Md. We were entirely scepticai OF ihis
h;sb Cement. and believed that human ingenuity
had exhausted itself IN vain without suggesting any
;mnrovement on the Clements used in our age; but
in this we we're agreeably disappointed by seeing
the application Of the Cement on the works refer
red to.

happy results to the world it is simple in It's man
ufacture and application, aud above all its cheap
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 aque-
duct formed with planks and the space hued WIN
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
,be appearance of a dark marble basin, perfectly
e.. c-oro nnraS with n beautiful lInn
polish. as tight as a bottle and as hard as IRON
thus making the work (Which bad been construc-
ted with other Cement, but failed,) perfectly light
and impervious to water; besides, by tins simple
/ process, the company have been saved the vast ex-
4 pense of rebuilding, which soon must have taken
4 Mace. as the pressure of the water had washed the
i old Cement away and left the pile OF stone a mere
1 skeleton, without any thing to bind together the
rock composing the structure. We have seen
where 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 Cement would
separate the bond which it formed with the stones.
We perceive from reading the pamphlet OF the
4 Patentee, containing certificates OF the important
n value of this Cement from the highest sources IN
Y our country, proving that which we had heretofore
4 believed impracticable, namely, the cementlng OF
Il atone work under water without the aid OF Golfer
y dams; this is effected in the simplest manner ina
q ENABLE, but the reader must see it applied before
he can form any idea of the important result ema-
mating from this Cement to our common country -
1t will, in our opinion, supeIsede the necessity OF
dressed stone altogether; it will cement any KIND
n of stone into one solid mass and become as hard
n a. granite in twenty-four hours; 1t can be moulded,
" sbaped, 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 rueberi
M this NAV seem strange but it Is Notwithstanding
. true, as hundreds have pr oved throughout the eoun-
81 try for the last two years. 1t seems to us that Mr..
ii CoYLE has laid his Cement fairly before the public,
d and IN doing so, he has shewn the practical results
n ofa ripe and energetic mind, which could only have
u been successful by energy of action and untirins
u zeal. This CemeDt is admirably adapted to all ny
n draulic purposes, such as ~fore.bays of mills, water
tanks. water-works, dams, piers, cisterns, granary
u floors, spring-houses troughs, ~rat-proof warehouses,
81 &c. sc. 1t will no doubt be found useful for many
N other purposes that experience alone VIII suggest
The subscribers, having purchased OF the Eaten
q tee the right for the State of Virginia, avail them
N 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- oraer, 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
Rocks, Md. JOHN HAM,
