One Of the chief interests, aside
from the values they have in RESPECT |
to forecasting. in the study OF charts
OF storm tracks. consists in comparing
them month with month, in order to
observe the changes that take place
with the progress of the scissors. II
was shown on the August map that
tile summer storms, In the majority OF
cases, originate in three places: III Al
berta, Colorado, and the West indies
On the other hand, In September the
chart Indicates that they arise IN a.
least six places. We have one set o.
storms generating In Alberta, at which
thirtv-cight were observed in ten years;
there were eleven noted that entered
the North Pacific coast OF the uni'eo
States; next FIVE were observed TO com
mence their activity on the northern
nlateau of the Rocky mountain dis-
trict, n,so seven developed over the
ISOLATED plateau of Colorado; five ap.
reared on the west coast OF the guif OF
Mexico: finally seven tropical hurri-
canes came in from the West Indies.
These all pursued their paths to the
gulf OF ST. Lawrence. in the neighbor-
| hood of which they left the Held OF Oh
servation. The Alberta storms run
| along the northern boundary OF the
| United States in the northwest, cross
the lake region. and advance down the
st. Lawrence valley. reaching the gull

tendency to loop down near the Begin

mountain slope into North and South
Dakota, whence they recover the main
track in the neighborhood OF Lake
