Great improvements in the application of
steam.
On Monday last examined Il saw-mill, now
| in operation at Carondelet, owned by Mr.. Kenneth
Mackenzie, and. propelled by machinery invented
I by Mr.. James A. Stewart, Of Tennessee.
| We have never in our lives been more agreeably
surprised than in the examination of this machine
ry, The principle OF the application OF the steam
is so perfectly simple, the machinery occupies 50
small space, and is so very cheap compared with
the old steam engine, that We could scarcely be
lieve our own eyes, we saw it operating with
such power and precision. SO far as we capa-
BILE Of Judging, il s vast improvement over all
other methods yet invented for the application OF
steam power. and we can perceive no reason why
boats or any other purpose for which steam j. now
used. Whilst we were present, hard and sea
soned oak log, OF near two feet in diameter, was
being sawed into plank and the rapidity viii,
which it was accomplished afforded conclusive ey;

ly credible that simple affair, enclosed in a
little box about two ieet square, could produce such
powerful results

to produce great change, il not entire revUlu-

much about mechanism, but in five miGutes obser-

mill and OF the engine, which may be relied upon
