We we're led to these reflections by observing

had exhausted itseIf,n vain without suggesting 40.
improyement on the Clements used IN our age out
in this we were agIeeably disappointed BY seeing
the application Of the Cement on the woiks REFER

We have seen the skeleton OF the w8llo an aQue-
duct formed with planks and the space h'ieh WIN
stones and Cement, and when the planks were re-
moved, and after the Cement became hard, the
whole walls and bottom Of the a%queduct presented
the appearance OF a dark marble BASIN, perfectly
clear and free from pores, with a beautiful hlgh

thus making the wolk (Which had been constrGc-
ted with other Cement, bat failed, } perfectly tight
and impervious TO water besides, by this simple
process, the company have been saved the vast tx
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 Cement would
separate the bond which il formed with the stones.
We perceive from reading the pamphlet OF The
containing certificates of the important
value of this Cement from the highest sources IN
our country, proving that which we had heretofore
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 -
Il will, in our opinion, supeIsede the necessity OF
dressed Stone altogether; it will cement any kind
,f stone into one solid mass, aud become as hard
IS granite in twenty four hours; ii can be moulaed,
shaped. or formed into any wall, vessel, pier, or

has laid his Cement fairly before the public,
md in doing so, he has shewn the practical results
ia ripe and energetic mind, which could only have
successful by energy of action and untiring

rnulic purposes, such as ~fore.bays of mills, water
anks, water-works, dams, piers, %cisterns, graDary
oors, spring houses troughs %rat-proof warehouses,
&c. &c. 1t will no doubt be found useful for many
