Having condemned the present machinery Of steam
boats as obsolete behind the age and reducing the
profits and increasing the first expense, we deem il
duty boldly state what consider would be great
progressive step.
Every steamship should be built of iron, with COM
partments reaching above the water mark; with them
she could founder being built of iron she could
not burn.
No steamship should use salt in her boilers.
To do so is disgraeeful TO science Distilled water oy
should be allowed to be used. The Emerald a small
boat Southampton, used distilled for long
time; her condensers were made by Mr. Humphreys.
Where The ocean is at hand there is difficulty in
densng the steam which has passed the engines and
returning the obtained to the tanks. 1t is
mere question Of proportional surface and quantity of
water. The tanks III accordance with the size of the
vessel, may placed amdships on both sides of the

being practicable No company has yet been spirited
enough to adopt it. Is It from the want OF enterprise,
knowledge or money? Perhaps il arises from
