MIR. EDIT0R:--Ihc Improvements now ns'
INl ly taking place II the arts and sciences, Dla
~ naturally 10 infer still greater results from tbe
spirit Of enquiry that has taken such deep root with
the people.' We could indeed wish our Govern
ment more disposed to counfenance scientific men
and scientific pursuits--but so long as the Goyern-
ment IL the creature, II viii be also the instrument
Of the peoples will. Individual enterprise, there
fore. must and can accomplish In America, what
monarchical patropags has done in Eurore. The
vast discoveries that are s~pfinging up daily IN eve
nv mart Of our land. in the cultivation Of the ilne
and mechannihcaI arts, forbid US TO despair that orr
beloved country will be other Than foremost IN the
race Of scientific pursuits; to accomplish which.
does ii not behooyc every lover Of bis country and
its system Of Government, TO show 10 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 Cotoctiu aqueduct on The
Chesnpeske and Ohio Canal, of a new and peculiar
kind OF Cement, patented by 4. c. CoYLE, OF Bal
timore, Md. We were entirely scepticai OF TINS
hish Cement, and believed that human ingenuity
had exhausted itseIfm vain without suggesting any
Improvement on the Clements used in our age; but
In this we were agteeably disappointed BY seeing
the application Of the Cement on the works refer
red TO.
This new improvement bids fair 10 revolutionize
in a great measure the mechanic arts with the most
happy results to the world; il Is simple IN it's man
ufacturc and application, and above all its cheap
ness, as the materials Of which il is composed are
TO be found every where.
We have seen the skeleton Of the vol of an aque-
duct formed with planks and the space filled with
stones and Cement, ard 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 q beautiful high
polish, as tight as a bottle and as hard as IRON
thus making the work (Which had been consiruc-
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 be water had washed The
old Cement away and left the pile Of stone a mere
skeleton, without any thing 10 bind together the
rock composing the structure. We have seen
where the Cement was thrown rromiscrensly on
hard mountain rock which formed the arch OF The
work, and when the sledge or crowbar was applied,
the rock invariably broke before tie Cement would
separate the bond which il 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 cementlng OF
stone work under water without the aid OF Golfer
dams ; this is effected in the simplest manner ina

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 oil
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, OF
arch which may be required, or, ii desired, the
Cement can be made as elastic as India rubber;
this may seem strange but it is Notwithstanding
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,
and in doing so, he has shewn the practical results
ripe and energetic mind, which could only have
been successful by energy of action and untiring
zeal. This Cement is admirably adapted TO all ny
draulic purposes, such as lore bays oil miiip, watef-
tanks, w~ater-works, dams, piers, cisterns, granary
floors, spring-houses troughs, %rat-proof warehouses,
&c. &c. 1t will no doubt be found useful for many
purposes that experiences alone will suggest.
The subscribers, having purchased OF the Peten-
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 at the Point oil hocks,
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 al the Point Of
Rocks, Md. JOHN HAM,
PHILIP MCLAUGHLIN.
Or to WILLIAM {. CLAHk,
of Harpers-Ferry Jefferson County, Va, who Is our
general Agent for the State.
