Nh n. EDIToR.-The improvements now dali
w ly taking place in the arts and sciences, bid
us naturally to infer still greater results from the
split Of enquiry that has takcn such deep root with
the people. We could Indeed wish OOH Govern
mont more disposed 10 countenSnces scientific men
ard scientific pursuits-but 30 long as tbs Govern
mcnt is the creaturc, i, will be also the instrument
Of the peoples will. Individual enterprise. ihere-
fore, must aud can accomplish in America, what
monarchieal patronage has done in Eurore. The
vast discoveries that arc sptingiag w daily in eve
~ part Of cur land, 10 the cultivation at tie hne
and mechanical ssts, forbid ne 10 despair thai our
beloved country will be other than foremost in the
race ef scientific pursuits TO accomplish which.
does il not behoove every lover Of his country and
is systan Of Government, 20 show to the world
thar man constitutes a state, and what kings. prin.
ces, and mobiles can DO in Europe, men can do
here.
We were led to those reflections by observing
The application. at The Cotoctin aqueduct on the
Chesapeake and Ohio Canal, Of o new and peculiar
Kind Of Cement. patented by l. c CoYLE, Of Bal.
timorc. Md. We were entirely .oeptical ct this
high Cement. aud believed that human ingenuity
had exhausted tselftn vain without suggesting sny
improvement on the Clements used Ia our age, but
IN this We we've as,eeably disappointed by seeing
the application OF the Cement on the works refer
rcd 10.
This new Improvement bids fair 10 revolutionixe
in a grcn, measure the mechanic arts with the most
happy results 10 the world it is simple IN It's man
ufacture and application, and above all its cheap
ness, as the materials of which IL ia composed are
to be found every where.
We have seen the skeleton Of the eall Of an aque-
duet formed with plsnks and the space filled with
stones and Cement, and when the planks we're re-
moved, aud after the Cement became hard, the
whole walls ard bottom Of. the ~equeduct presented
the appearance of a dark marble basin, perfectly
clear and free from pores, with u beautiful high
polish. a. tight as a bottle and as hard "a iron--
thus making tho work (Which had been constrnc-
ted with other Cement. but failed perfectly tight
and imperviaus TO water bcsides, by this simple
process, the company have been saved the vast *
penss of rebuilding, which soon must have taken
place, as the pressure OF tho water had 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 promiseuously on
hard mountain rock which formed tho arch OF the
work, and when the sledge or crowbar was applied,
the rock invariably, broke before the Comcn, would
separate tho bond which il formed with the stones.
We perceive from reading tho pamphlet vt the
Putentee, containing certificates Of the important
value Of this Cement from the highest sources in
our country, proving that which We had heretofore
believed impraciicable, namely, the cemeniing Of
stone work under water without the aid OF collier
dams this i. effected in the simplest manner ina
| ginsble, but the reader must see il applied before
he can form any idea Of the important, result cma-
mating from this Cement 20 our common country
IL will, in our opinion, supefsede the necessity oil
dressed stone altogether; IL will cement any kind
Of stone into one solid mass, aud become AS hard
rs granite in twenty four hours II team be moulded,
shaped, or formed into any wall, vessel, pier, OF
arch which may be required, or, II desired, the
Cement Gun be made as elastic as India rubber
this may seem strange but It IL Notwithstanding
true, az hundreds have proved throughout the eoun-
try for the last two years. II seems TO IA thai Mr..
CoYLE has laid his Cement fairly before the public,
and IN doing so, be has sllewn tho practical results
Ola ripe and enet sefie mind, which could only have
been successful BY energy of action and untiring
zeal. This Cement is admirably adapted TO all by
druulie purposes, such as ~foresbays OF mills, water
tanks, water-works, dams, piers, %cisterus. granafy
floors. springAlonses troushs, rat )roof WA shouses,
&c. Sc. Ii will no doubt be f. und 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 milking known
to the citizens of Virginia that they are now manu-
featuring the above Cement at the Point Of Rocks.
where any quantity can be furnished 10 order. We
will also sell the rights for Counties, Cities, Towns,
Districts, Farms or Buildings Applications to be
made to the subseribers living At the Point OF
