1vl- ly taking place in the arts and sciences, bid
us naturally to infer still greater results from the
spirit of enquiry thet has taken such deep root with
the people. We could indeed wish our Govern
ment more disposed to countenance scientific men
and scientific pursuits-but so long us the Govern
ment is the creature, ii will be also the instrumen,
of the peoples will. Individual enterprise, there
fore, must and can accomplish in America, what
monarchical patronage has done in Europe. The
vast discoveries that are s~pringing up daily in eve
ry part of our land, in the cultivation of the fine
and mechanical arts, forbid ia 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 state, and what kings, prin.
ces, and mobiles can do in Europe, men can do
here.
We were led to these reflections by observing
the application, at the Cotoctin aquedpct on the
Chesapeake and Ohio Canal, of a new and peculiar
kind of Cement, patented by I. c CoYLE, of Bal
timore, Md. We were entirely s~ceptical of this
high Cement, and believed that human ingenuity
had exhausted itselfin vain without suggesting any
improvement on the Clements used in our age; but
in this we were agreeably disappointed by seeing
the application of the Cement on the works refer
red to.
This new improvement bids fair to revolutionize
in a great measure the mechanic arts with the most
ndpIy results 10 tue WOitu, IL IL SIMPLE In Its man

ness, as the materials of which it is composed are
to be found every where.
We have seen the skeleton ofthe wall of an auue-
duct formed with planks and the space filled with
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
the appearance of a dark marble basin, perfectly
clear and free from pores, with a beautiful high

thus making the work (Which had been cons,ruc-
ted with other Cement, but failed } perfectly tight
and impervious 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 had washed the
old Cement away and left the pile of stone a mere
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 sedge 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 pamphlets 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 cementing OF
stone work under water without the aid of Golfer
dams; this is effected in the simplest manner ina-
glnable, 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, supetsede the necessity Of
dressed stone altogether; it will cement any kind
OF stone into one solid mass, and become as hard
as granite in twenty -four hours; it 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 rubber
this may seem strange but it is Notwithstanding
true, as hundreds have moved throughout the coun-
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 untiriug
zeal. This Cement is admirably adapted to all hy.
