us naturally to infer still greater results from the
sn;sit &c epauiry that has taken such deep root with
the people. We could indeed wish our Govern

vast discoveries that are springiag up daily IN eve

and mechanical arts, forbid us 10 despair that our
beloved country will be other than foremost IN the
ace Of scientific pursuits; TO accomplish which,

that man constitutes a state, and what kings, prln'
ces. and mobiles can do in Europe, men can do
here.
We were led TO these reflections by observing
tho application, at the Cotoctin aquednct or the
Chesapeake and Ohio Canal, Of a new and peculiar
Mind of Cement, patented by T. c CoYLE, Of Bal
dmo,e. Md. We were entirely sceptical OF TINS
bigh Cement, and believed that human ingenuity
had ex haus,ed itseIfln vain without suggesting any
;mnrovement on the Clements used in our age; but
h III. We were agreeably disappointed BY seeing
the application of the Cement on the works refer
red to-.
This new improvement bids fair to revolntionize
in q great measure the mechanic arts wIththe most
harry results to the world; III slinpie lnits man
ofacture and application, and above all its cheap
ness, as the materials OF whlch u Is compose u
to be found every where.
We have seen the skeleton ofthe wailo u an aqae-
dnet formed with planks and the space filed with
stones and Cement, and when the planks were re-
moved, and after the Cement became hard, the
whole walls and bottom Of the aqneduct 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 construc'
ted with other Cement, bat iailed,) perfectly tgnt
and impos yious 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 bad washed the
old Cement away and left the pile Of atone a mere
skeleton, without any thing 10 bind together the
rock composing the structure. we have seen
where the Cement was thrown promlscuousiy 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 IN
our country, proving that which we bad heretofore
believed impracticable, namely, the cemcntiug of
stone work under water without the aid Of Golfer
dams this is effected in the simplest manner ina
ENABLE. 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
1t will, in our opinion, supeIsede the necessity OF
dressed stone altogether; it will cement any kind
oc stone into one solid mass, and become as hard
as granite in twenty four hours; 1t 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 rfbber;

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,
in doing so, he has shewn the practical results
ripe and energetic mind, which could only have
been successful by energy OF action and untlring
zeal. This Cement is admirably adapted to all by
dra,lic purposes, such as fore,bays of mills, water
water-works, dams, piers, %cisterns, granary
floors, spring-houses troughs, rat-Proof warehouses,
&c. 1t will no doubt be found useful for many
other purposes that experience alone will 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-
the above Cement at the Point OF Rocks,
where 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,
