Us naturally 10 infer stili greater results hom The
spitit Of enquiry that has taken such deep root With
The people. We could indeed wish our Govern
ment niofe disposed 10 eeuntenancc scientific men
and scientific pursnits--but so long as the Goyern-
nenl Is tho creature, ii will be also the instfgmenl
Of the peoples vail. Iadiyidual entetpfise, there

rnonarehical patronage has done in Lurore. The
vast discoveries THAT are splIngiug up daily IN eve

aud faeeitsnical arts. forbid Us to despair that our
beloved country viii be other than foremost % the
race OF scientific pursuits; TO accomplish whicn,
does il not behooye every lover OF his country ana
its system Of Government, 10 show 20 the world
that man constitutes a state, and wha. kings, rfin'
ccs, and mobiles Gun DO ID Europe, men can 40
here.
We were led 10 these reflections by observing
the application, nj he Cotoctin aqaedgct on the
Chesapeake and Ohio Canal, Of a new ana peculiar
kind Of Cement, pntcnted BY TIC CoYLE, % Bal
tirnote, Md. We we're ettiEsly scepticai OF una
high Cement, and believed that human ingenuity
had exhausted itself III vain without Suggesting any
Improvements on tho Cemcnss used 10 our asei but
ia THE we were agieeably disappointed by seeing
tho application Of tho Cement on tiie works refer

in a great measure the mechanic arts with tho most
happy Iesalis to the world; il il simple IN It's man
u~taciute and application, and above oil its cheap
ncss, ss the materials OF which il is composed are
to be found every where.
We have seen tho skeleton oftho wall Of nm aque-
duct formed With pIanks and the space filed with
stones and Cement, and when the planks we're re-
moved, and after the Cement became hard, The
whole walls and bottom Of the ~aqueduct presented
ihe appearance ai a dark marble baein, perfectly
clear aud free from pores, with "A beautiful high
polish, rs tight as "a bottle and as hard as ron
thus making the work (Which had been c%onsttue.
ted with other Cement, but failed perfectly tight
and inpetyious TO water besides, by THIS simple
process, tie company have been sayed 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 u mere
skeleton, without any thing TO bind ~iogether the
rock composing the structure. We have seen
whore The Ccnient was thrown rroniscuously on
hard mountain rock which formed the arch OF the
" DIRK, and when the slodgc or crowbar was applied,
the rock invariably broke before the Cenen, would
separate The bond which it 4 formed with the stones.
We perceive from reading the pamphlet OF the
Patcntcs, containing certificates OF tho important
value of llis Cement from the highest sources in
our county, proving that which wc had heretofore
believed impractieable, namely, tho ceinentlng OF
stone work Under wafer without the aid OF Golfer
dams this is effected ia The simplest manner ina
ginuble, but the reader NUT see it applied before
lie can form any idea Of the important result ema-
nating from this Cement to our common country -
1t will, in our opinion, sut,etsede the necessity Of
dressed stone altogether; it will cement any kind
Of stone into one solid nlass, and become as bard
as granite in twenty four hours II can be moul4ed,
shaped. or formed into any wall, vessel, pier, OF
arch which may be required, or, il desired, tile
Cement can be mndc as elastic as India RUBBER
this may seem strange but II IS Notwithstanding
true, us hundreds have proved throughout the eoun-
try for the Inst two years. IL seems 10 us that Ar.
CoyLB has laid his Cement fairly before the public,
and 10 doing so, he has shewn the practical results
ola ripe and energetic mind, which could only have
been successful by energy OF action and untrlng
zeal. This Cement is admirably adapted to ali hy-
draulic purposes, such as fore bays OF mills, water
tanks, water-works, dams, piers, %cistcrns, gtanary
floors, spring-houscs troughs, rat-proof warehouses,
&c. Sc. 1t will no doubt be found useful for many
other purposes that experience ulone viii suggest.
The subscribers, having purchased of tho Paten-
too the rieht for the State OF Virginia, avail them
selves Of the present opportunity OF making known
TO the eitizens of Virginia that they are now manu-
featuring the above Cement al tho Point OF Rocks,
where any quantity can be furnishcd TO order. We
will also sell the rights (or Counties, Cities, Towns,
