FULL INSTRUCTIONS BY A VETERAN SALT.

The brief but pthy description given below OF the
indications OF impending cyclones or hurricanes
4ogether with advice to the best way TO steer
clear OF such dangerous winds, Is from the pen OF
one OF our most experienced practical navigators
and will command the attention OF every American
Bhipmaster. The charts and tables. which we also
publish, Illustrate the points enforced and the cOuh-
sci given. Few branches OF nautical science nave Q"

pould be accounted for by the existing wind or by
that which has ever recently existed In the neigh

In contact with Its outer margin. and that 1t is
kime for the captain to Immediately prepare and
Hirect his vessel accordingly.
. II In the Northern Hemisphere, the first thing to
be done Is to bring the ship by the wind on
The starboard tack, to shorten sail and deaden
her way much as possible; then determine
parefully by the compass how the wind veers, or
whether it vecrs at all. The wind OF hurricane
