lvl- ly taking place IN the arts ana sciences, ~
as naturally to infer still greater results from The
spirit of enquiry that has taken such deep root With
he people. We could indeed wish our Govern
ment more disposed to counienance scientific men
and scientific pursuits-but so long as the boVern-
ment is the creature, it will be also the Instrument
of the peoples will. Individual enterprise, there
ore, must and can accomplish IN America, what
nonarchical patronage has done ~ EufoTe. Inc
vast discoveries that are sprngiug up daily IN eyes
nv part of our land, in the cultivation OF the hne
and mechanical arts, forbid US to despair that our
beloved country viii be other than foremost ~ the
race of scientific pursuits to accomplish which,
does it not behooye every lover OF his country and
its system Of Government, TO show 10 the world
that man constitutes a state, and what kings, pFn.
ces, and mobiles can do in Europe, men can 90
here.
We were led to these reflections by observing
the application, at the Cotoctin nqneduct on tue
Chesapeake and Ohio Canal, Of a new aud peculiar
kind OF Cement, patented by T.. c CoYLE, OF Bal
timorc, Md. We were entirely sceptlcai OF TINS
high Cement, and believed that human ingenuity
had exhausted itselfin vain without suggesting any
improvement on the Clements used IN our asei Dut
in this we were agfecably disappointed by seeing
the application Of the Cement on the woiks refer
red to.
This new improvement bids fair to reyolution'ze
in a great measure the mechanic arts withthe most
happy results to the world it is simple IN It's man
ufacture and application, and above all ITS cheap
ness, as the materials of which it is composed are
to be found every where.
We have seen the skeleton ofthe wall OF an aque-
duct formed with planks and the space h'led with
stones md Cement, and when the pianks 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 hlgn
polish, as tight as a bottle and as hard as IRON
thus making the work (Which had been constrnc-
ted with other Cement, but failed, J perfectly light
and imperyious 10 water; besides, by TINS SIMPLE
process, the company have been saved The vast eX-
nense 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 q mere
skeleton, without any thing to bind together the
rock composing the structure. we nave seen
where the Cement was thrown promlscuously 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 had heretofore
believed impracticable, namely, the cencnlihg OF
stone work under water without the aid OF Golfer
dams; this is effected in the simplest manner ina
ginable, 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, supefsede the necessity OF
dressed stone altogether; 1t will cement any h'hd
of stone into one solid mass, and become as nara
as granite in twenty -four hours; 1t can be mouided'
shaped, or formed into any wall, vessel, per, or
arch which NAV be required, or, if desired, the
Cement can be made as elastic as India rubber;
this may seem strange but 1t - Notwithstanding
true, as hundreds have proved throughput the eoun-
try for the last two years. 1t seems TO US that Mr.
COVE 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 nave
been successful by energy of action and untirlng
zeal. This Cement is admirably adapted to ali ny
draulic purposes, such as fore bnys OF mills, water
tanks, water-works, dams, piers, cisterns, granary
floors, spring-houses troughs, %rat-proot warehouses;
&c. &c. 1t will no doubt be found usetultof many
other purposes that experience alone WI 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
to the citizens of Virginia that they are now manu-
featuring the above Cement st the Point ct kocks,
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
