NNR. EDITOR:-The Improvements now dali
IVA ly taking place 10 the arts and sciences, bid
us naturally TO infer still greater results from the
spirit of enquiry that has taken such deep root with
the people. We could indeed wish our Govern
ment more disposed to counienance scientific men
and scientific pursniis-bnt 80 long as the Govern
ment is the creature, il viii be also the instrument
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
nv mari of our land. in the cultivation Of the line
and mechanical arts, forbid ne to despair that Our
beloved country will be other than foremost in the
race Of scientific pursuits; to accomplish which,
does il not behoove every lover OF bis 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 aqueduct on the
Chesapeake and Ohio Canal, Of a new and peculiar
kind OF Cement, patented by T. G CoYLE, OF Bal
timore. Md. We were entirely sceptical 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 agrceably disappointed by seeing
the application OF the Cement on the WORKS refer
red to.
This new improvement bids fair to revolutionize
in q crea, measure the mechanic arts with the most
happy results to the world il is simple IN its man
ufactlIre and application, and above all its cheap
ness. as the materials Of which Il il composed arc
to be found every where.
We have seen the skeleton Of the wall OF an aque-
duct formed with planks and the space allied 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 b@attitul high
polish. as tight as "A bottle and as hard as ron
thus making the wolk (Which had been constrnc-
ted with other Cement, but failed perfectly tight
and impervious TO wateri besides, by TINS slmpie
process, the company have been saved The vast e%-
rense 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 stone a mere
skeleton, without any thing to bind together the
rock comnosing the structure. We have seen
where the Cement was thrown promlseuously 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 impracticabie, namely, the cementing 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 it applied before
he can form any idea Of the important result ema-
mating from this Cement 10 our common country -
1t will, in our opinion, supeIsede the necessity OF
dressed stone altogether; it will cement any kind
Of stone into one solid mass, and become a. hard
as granite in twenty.fou hours; team be moulded,
shaped, or formed into any wall, vessel, pier, or
arch which may be required, or, II desired, the
Cement can be made as. elastic as India rubber;
this may seem strange but 1t is Notwithstanding
true, as hundreds have proved Throughout the eoun-
try for the last two years. II seems 10 IA that Mr..
CoYLE has laid bis Cement fairly before the public,
and in doing so, he has shown the practical results
off ripe and energetic mind, which could only have
been successful by energy of action and untiring
zeal. This Cement is admirably adapted TO all by
draulic purposes, such as fore, bays OF mills, water
tanks, water-works, dams, piers, cisterns, granary
floors, spring-houses troughs, %rat-proof warehouses,
&c. Sc. 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
TO the citizens Of Virginia that they ae now manu-
featuring the above Cement at the Point of Rocks,
where any quantity can be furnished to order. We
will also sell the rights for Counties, Cities, Towns,
Districts, Farms or BUILDINGS Applications "a be
made to the subscribers living at the Point Of
