the northeast. During the development ahd progress of 
this low pressure area the barometer stood at about 30 
inches or above over the western portions of Oregon and 
Washington, and the general trend of the atmosphere was 
from the Pacific eastward across the divide toward-the low 
pressure area, and this was very marked after the 24th. 
Cloudless weather prevailed along the eastern slope on the 
26th and 27th. 
1889, August 6 to 8, Kansas .—Hot winds from the southeast to the south, 
west were reported on these dates from Wallace, Morton, Greeley, and 
Trego counties. No special features are noted except that the wind was 
strong and vegetation became withered and dry and corn was damaged 
in some localities. 
These winds accompanied an area of low pressure which 
appeared to the north of Montana on August 3, moved 
slowly eastward, and extended southward over the eastern 
slope until the 5th, when it divided into two distinct low- 
pressure areas, one to the north of Montana and the other 
over southeastern Montana. That to the north of Montana 
remained stationary, while that over the southeastern por¬ 
tion moved slowly southeast to northern Nebraska by the 
afternoon of the 7th, and both low areas moved rapidly to 
the lakes on the 8th. 
During the development and progress of these areas of 
low pressure the barometer stood about 30 inches along 
the coast of Oregon and Washington, and the general ten¬ 
dency of the atmosphere was well defined from the Pacific 
coast across the divide toward the low pressure area. Partly 
cloudy to cloudy weather prevailed to the west of the divide. 
Generally cloudless weather prevailed during the 5th, 6th, 
and 7th over the central and southeastern slopes. 
1889, August 19.—Hot south and southwest winds were reported from 
Decatur and Morton counties, Kansas, and Holt county, Nebraska, on 
August 19th, but no special features were reported. 
These winds accompanied an area of low pressure which 
made its appearance in the vicinity of Calgary on August 
42—Bull. Phil. Soc., Wash., Vol. 12.
