HYDRAULIC

INl iy taking place in 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 mors disposed to countenances scientific men
and scientific pursuits-bnt so long as the Govern
mont 10 the creature, it will be also the instrument
Of the peoples will. Individual enterprise, there.
fore, must and can accomplish in America, what
r1onarchicai patronage has done in Europe. The
vast discoveries that are s~pfinging up daily in eve,
~ part OF our land. in the cultivation Of rhe 6ne
and mechanical arts, forbid us TO despair that our
beloved country will be other than foremost in the
race OF scientific pursuits 10 accomplish which,
does 1t not bchooye every lover OF his 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
hero.
We were led to these reflections BY observing
the application, ut the Cotoctin aqueduct on the
Chesapeake and Ohio Canal, Of q new and peculiar
kind OF Cement, patented by I. G CoYLs, 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 agc; bot
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 . great measure the mechanic arts with the most
happy results to tho world il is simple in It's man-
ufacture and application, and above oil 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 aaue-
duct formed with planks and the space filed with
stones and Cement, and when the pIeDks 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 u beautiful high
polish, as tight as a bottle and as bard as IRON
thus making the work (Which had been construc-
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 rromiscuously 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 Cemenl 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 cemcntiug 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 erna-
mating from this Cement to our common country -
II will, in our opinion, supersede 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; ii can be moulded,
shaped, or formed into any wall, vessel, pier, OF
arch which may BIO required, or, if desired, the
Cement can be made as elastic as India rubber
this may seem strange but it is notwiihstandiug
true, as hundreds have proved throughout the eoun-
try for the last two years. Ii seems to US that Mr.
CoYLr has laid his Cement fairly before The public,
and IN doing so, he has shewn the practical results
OF a 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 milla, water
tanks, wa%ter-works, dams. piers, cisterns, granary
floors, spring-houses troughs, rat-proof warehouses,
&c. &c. 1t will no doubt be found useful FOR many
other purposes that experience alone sill 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 nj 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 10 be
