From msrch TO October, the prevailing wind along
the ceast and for many miles 20 the westward h fresh
L. NJ. and not unfrequently falling light during the
night During this Of the year the north~sst
wind blows with almost the regularity ofa trade wind
During the months Of August aud September logs pre-
vail TO great extent and impede and cndanser naVi-
During the part Of the year above mentioned .hers
are no heavy gales Of wind, aud little or no rsin
These winds cause current Of about haf knot per
hour along the coast setting to the souihward
Prem October to March the viud IL variable, both
With regard 20 velocity and direction. Daring this
season heavy gales occur from the souihsat, south
rain, and causing very heavy sea nnd swell along The
oottt.
The current during this season sets generally 20 the
Dothwsrd varying In velocity With the strength 81 ne

These facts being known. II Is now to be consdfsd
iIow directions fbould be given which would - ntt
pfsiul to navigation.
Sailing vessels bound to the norlhward from Mon
tsrey, any more northern port during the tummer
should stand well n shore net too close hauled
until about 200 miles from the land when they will be
beyond the influence OF the southery current aud IN
situation 10 take advantage Of slant Of vnd which
frequently occurs from the west north west They
would DO well not TO approach the land unless aTores
by the wind ss TO enable them to lay either their
course or nearly 80, until up with he latitude OF the
destined port.
Steamers should follow the coast from point to point
nearly as possible, always keeping within hfteen
miles Of the land. They will By this means shorteu
the distance end frequently avtid the strong nofsh-
west winds as often they will find u quite calm close
in with the shore where there Il strong wind to sea-
ward.
Vessels bound TO the northward in the winter sea-
son, should keep as cloee along the land az praocabe
and take every advantage Of all southerly winds TO
make latitude. They should slSays endestot to make
the land at least twenty thirty miles TO the south
ward Of the destined harbor.
Navigators bound TO the souhw ward should keep the
In sight and take advantage Of either tack upon
which the most latitude may be made, always making
the land TO the norhwsrd Of the port In susnner aud
to the southwsra In the winter season.
