Her ports are 15 feet above the load-water line. Her
height between decks is 7 feet 3 inches to the under side
of beams ! Her displacement at 23 feet draught is 5,440
tons. Her frame is of live oak, filled in below with yellow
pine, and crossed on the outside with two sets of diagonal
iron plates inclined in opposite direction. She is also
strengthened forward by similar diagonal plates laid across
the beams of the upper deck. Her plank of bottom and
decks are of yellow pine. Having a very fine run, she
is of course weak at her quarters, in consequence of
which Mr. Steers has fitted on each side a large 2-ineh
iron stay, or brace, which lies along the upper deck
beams, and passing through the decks below steps upon
the ster❑ post. This is certainly a curious arrangement
for a ship of war. It may as well be added here that
when she is docked it is thought necessary by Mr. Steers
to brace her two sides together, at about the turn of the
bilge, by means of a chain, which passes over a frame or
saddle, which is set up by wedges to tighten the chain.
She is rigged like the Merrimac and others.
The Niagara carries 12 guns, 5 of a side, and 2 pivot
guns, each of them 11 inches in the bore, and weighing
upwards of 7 tons. All the guns are mounted on pivoted
carriages, and the broadside ports have consequently to
be very large-9 feet long and 4 feet high. Through
ports of this size the guns would be easily dismounted in
close action, but the Niagara is intended to be fast, and
being furnished with long•rangeguns, is supposed to have
the power of annoying and injuring an enemy, while she
herself keeps out of the range of her enemy's guns. She
was, in fact, designed for the express purpose of giving
the Americans the advantage over all existing ships ; it
is satisfactory, however, for us to know that in our own
dockyards there are already several new class ships quite
competent to match her, and, if we are not mistaken, to
give a good account of Mr. Steers's experiment. We
should be pleased to know with certainty that such a
trial of strength is not likely to come off ; we hope it
never may.

The engines of the Niagara—designed by Mr. Cope-
land, and built by Pease and Murphy, New York—are
similar to those of the Merrimac, but she has three cylin-
ders, each 72 inches diameter and three feet stroke, in-
stead of two. Each frame for cylinders is cast in one
piece ; the cylinders have slide valves, and a separate
cut-off or expansion side-valve adjustable so as to cut off
at any point from three-eighths to five-eighths of the
stroke. Each cylinder has its own separate condenser,
air-pump, and hot well; in fact, there are three com-
plete engines, so that, should either become deranged,
the others would be still available. The screw propeller
(formed of composition) is 18 feet 3 inches diameter, and
4 feet 2 inches long, with pitch of 29l feet (at the peri-
phery.) The boilers are four in number, 11 feet long, 21
feet wide, and 15 feet high. Like those of the frigate,
they are Mr. Martin's vertical tubular. They are set in
pairs, the flues discharging into two chimneys.—Mccha-
