race Of scientific pursuits TO accomplish whlch,

4. svstem Of Government, to show TO the world
,ba, man eonstitutes a state, and what kings, prn'
res. and mobiles can do in Europe, men can DO
here. u
We were led to these reflections by observing
tho annlicatiop. Mt the Cotoctin s~qneduct on the
Chesapeake and Ohio Canal, of Q new and peculiar
kind Of Cement, patented by &c CoYLE, oil par
timore. Md. We were entirely sceptlcal OF tni'
high Cement, and believed that human ingenuity
had exhausted itseIfin vain without suggesting any
;mprovement ON the Clements used in our age; but
in hi. we were agteeably disappointed by seeing
the application Of the Cement on the works refer
red to-. -
This new improvement bids fair to revoiutionize
in a grea, measure the mechanic arts with the most
happy results to the world; it is simple IN us man
nfacture and application, and above all its cheap
meas. as the materials Of which it is composed are
to be found every where.
We have seen the skeleton ofthe walio oil an aque-
duct formed with planks and the space hiled WIN
stones and Cement, and when the pIahks "e.o
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
tbps making the work (Which had been construc-
ted with other Cement, but failed perfectly tght
and impervious to water; besides, by TINS 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 toge'ser 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 inya riably broke before the Cement wouid
separate the bond which it formed with the stones
We perceive from reading the pamphlet OF the
Pa,en,ee containing certificates of the important
value of this Cement from the highest sources IN
our country, proving that which we had heIe'oi'ie
believed impracticable, namely, the cemeniing OF
stone work under water without the aid OF Golfer
dams. TINS is BHcCLPd III u oihifiiNoh E"'" 'N
cinable. 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
IL 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 nara
az granite in twenty four hours; 1t can be noulded,
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 ruooer;
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..
CoYLE has laid his Cement fairly before the public,
and IN doing so, he has shewn the practical results
ola ripe and energetic mind, which could only have
been successful by energy of action and untlring
zeal. This Cement is admirably adapted to all ny
draulic purposes, such as ~tore.bays OF mills, water
tanks, water-works, dams, piers, cisterns, granary
floors, spring-houses troughs, rat-proof warehouses
&c. &c. 1t will no doubt be found useful for many
other purposes that experience alone will suggest.
The subscribers, having purchased ofthe Paten-
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,
any quantity can be furnished to order. We
also sell the rights for Counties, Cities, Towns,
Farms or Buildings Applications to be
made to the subscribers living at the Point of
Rocks, Md. JOHN HAM,
