gust. Inns chart SheWs. among many )tl6r
matters, the course OF the cyelollc storms
which have been reported in the month Of
July. There have been noae OF tropical
origin. Three III the far north, beyond the
track OF the transatl ante steamers, have
been observed, and these with apparently
short courses.
Accompanying the chart is a most valuable
and interesting supplement. It IS large
sheet containing 6 maps Of the North AtIln-
tc III wo series, an upper and a lower, OF
maps each. The upper series snsws the
tracks Of cyc!0uic storms traSerSiag the Com
tIaeAt IN tile three months Of August. S1ptem-
Der ana October, respectively y. far th-iperloi OF
SIX years, 1888 to 1898 inclusive. lie lower
series shews for the corresponding periods the
tracks If storms proceeding from the tropics.
The sheet contains also the following notes,
calling attention to some of the more striking
results If the comparison between the two
classes of stoyms.
-rho graphic presentation OF the tracks Of
aloas If depression for a period OF SIX years,
during the months of August, September and
October illustrates the great preponderance Of
cycIonic disturbance traversntg the United
States over those which proceed up the coast
in the general direction Of the Gulf Stream.
50 much has been written about the dreadful
ravages of the West Indian hurricanes that
they have come to be regalte ed by some as
the only class Of storms which prevails dur
ing these months, Although they are usual
" violent when they occur, yet facts shew
that the storms which travel eastward into
the ocean from across the continent are more
frequent and require seamsn to be equally
vigilant to manumyre their vessels properly.
Astuly Of the general conditions indicates
that during August and September the land
storms usually enter the Atlantic across New
foundland ana Labrador, while in October
tile storms from over the land reach the
Atlantic Coast and enter the Atlantic all
along from Cape Hatteras to Newfoundland.
From observation, it will be seen that the
tracks of many Of the tropical storms are
quite irregular and that instead Of following
curves Of regular shape, they sometimes are
DETECTED abruptly or prevented from curving
until the higher ATTITUDES are reached.
When special management of q vessel in q
storm is desirable, it is essential that the
master Of the vessel should know;
First. At least the general beAring'of the
storm center. Second. At least the general
erection in which the storm is moving.
Owing to the Irregular y IN the shape Of
the c|yclonic area it is oftentlmes very difficult
to determine these points from a single sta
ton point, such as the deck OF a ship. In
order to come to a correct decision on the

the habit of studying the weather continuous
ly. He should not wait until the storm is
upon him and then endeavour to reach a
decision. This series of charts has been pre-
pared with special reference to the second
point and may be regarded as a forecast OF the
storm tracks for each month.
at is seen that storms off the coast of the
United States come in great number across
the continent, or in less number up the coast
from the tropics. The seaman will be very
much aided in reaching a decision if he can
simply determine from which Of these two
genera al sources the storm is coming, as, by
this knowledge, he may be able to determine
in which semi circle Of the storm area his
vessel i placed. For illustration, let us
assume that q vessel is in the N. b. quadrant
of a storm area, bearing n. E. from the storm
centre. 1t is obvious that the vessel is in
the left semi-circle, with reference to the
track, if the storm is moving from the con-
tinent in an easterly direction, and that she IS
in the right semi-circle if the storm is COM
ing up the coast in a northerly direction. 1t
should be noticed, however, hat we'll to the
eastward, in the high ATTITUDES, the general
direction taken by the tracks of those two
classes of storms is practically identical.
