of the working cylinder. is the same. A pair of
these cylinders is placed each side the shaft The
power can be increased by enlarging the diameter
of the cylinder. 1t Yves originally intended TO

the fame. The cylinder above the fires is / 2

strength. Even were it to break, the contents of
the cylinder would pass off harnlessly. There is

The engine in the E. is of 600 horse power, and
not more than seven tons of coal per day can pos-
sibly be consumed. In a steamship of the same
power, sixty tons.per day would be low caicula-
tion. Mr.. Ericsson stated further that this ship
was started before she was finished because it was
said to be dead failure, and the effect was preu-
icial the interests of those concerned with him
in the enterprise But the result had far exceed
ed his anlicipatons. But half pound to the
square inch was necessary TO start the engines.
The weight of the crank alone was sufficient to do
4 this.
i As to the comparative expenses of running a
breathing ship at high or low rate of speed, MIR.
E. stated that it about as cheap. as far as the
engine was concerned, TO run ten miles per hour
as less.

jections which had been urged relative to the
packing" and ' oxidation " of the cylinder, &c.
which he did 10 the satisfaction of all; and indi-
viduas who had previously been incredulous as te
the probable success of the Ericsson, acknowledged
that all doubt on their part was now dissipated.-
Mr.. Ericsson stated that for twenty FIVE years he
, had been maturing this invention. Many Difficult
ties had presented themselves, but time, only wa:
required to remove them. Prof. Furaday, Alex
Ure, and others. had long since predicted it's sue
cess, and he now saw no practical defect in the
engine. 1t would last much longer than the shiv

could wear out.
The current expense of running it he had no
estimated, but the difference would not be NOR,
than one fifth compared with the steam engine
The original cost of the engine would also be less
