on the morning of September 8, moved- slowly eastward, 
developing into a V shaped depression, which extended 
south on the 11th to Kansas. From the 12th to the 13th 
this depression remained stationary and then moved off 
slowly to the eastward. During this time the pressure was 
about 30 inches over the western portions of Washington 
and Oregon, with cloudiness and rain and a fairly well de¬ 
fined tendency of the atmosphere to cross the divide toward 
the area of low pressure. 
During the development of the low pressure area over the 
eastern Rocky Mountain slope an intense cyclone moved 
from the central portion of the Gulf of Mexico northward 
to Nova Scotia. (See plate 4.)

west winds proved very injurious to crops.”* 
These winds accompanied an area of low pressure which 
was apparently developing over Wyoming on July 18 and 
was over the central portion of the eastern slope, with its 
greatest' depth in Kansas and Nebraska from the morning 
of the 19th until the morning of the 23d, after which it 
moved rapidly eastward and reached the lower lakes on the 
morning of the 24th. During the development and progress 
of this low pressure area an area of high pressure was off 
the coast of Oregon, with pressure above 30.20 inches. With 
few exceptions, reports from the Pacific slope were missing 
and very little information was at hand from which to draw 
conclusions as to the general direction in which the atmos¬ 
phere was moving, but conditions, it appeared, were such 
as would force it from the Pacific slope across the divide 
toward the low pressure area.

An area of low pressure extended over the plateau region 
from Fort Garry to Yuma on the 10th and 11th, deepened 
over the central Pocky Mountain slope on June 12th, and
