In tracing resemblances there is a tendency not only to overlook
points of difference, but to exaggerate points of likeness,--to be
fanciful. It may be so considered to point out that as the
sailing-ship had guns of long range, with comparatively great
penetrative power, and carronades, which were of shorter range but
great smashing effect, so the modern steamer has its batteries of
long-range guns and of torpedoes, the latter being effective only
within a limited distance and then injuring by smashing, while the
gun, as of old, aims at penetration. Yet these are distinctly tactical
considerations which must affect the plans of admirals and captains;
and the analogy is real, not forced. So also both the sailing-ship and
the steamer contemplate direct contact with an enemy's vessel,--the
former to carry her by boarding, the latter to sink her by ramming;
and to both this is the most difficult of their tasks, for to effect
it the ship must be carried to a single point of the field of action,
whereas projectile weapons may be used from many points of a wide
area.

The relative positions of two sailing-ships, or fleets, with reference
to the direction of the wind involved most important tactical
questions, and were perhaps the chief care of the seamen of that age.
To a superficial glance it may appear that since this has become a
matter of such indifference to the steamer, no analogies to it are to
be found in present conditions, and the lessons of history in this
respect are valueless. A more careful consideration of the
distinguishing characteristics of the lee and the weather "gage," (3)
directed to their essential features and disregarding secondary
details, will show that this is a mistake. The distinguishing feature
of the weather-gage was that it conferred the power of giving or
refusing battle at will, which in turn carries the usual advantage of
