SUMMER HOT WINDS ON THE GREAT PLAINS. 323 
1889, July 14 to 19, Gibson, Kansas.—' “ Hot winds from the southwest 
on the 16th and 17th, the heat coming in puffs and rolls.” Chas. M. Bell, 
voluntary observer. 
1889, July 14 to 19, Indian Territory, Fred, Chickasaw Nation. —“ Hot 
winds ; direction, southwest; temperature, 106°; very parching and drying 
to all grass and vegetation, especially melon vines and the tassel or top of 
growing corn, while just under the ground, about one inch, the soil is 
plenty moist for growing vegetation, and I have seen corn crops ruined in 
ten days. When the corn ear is just forming the wind would come and dry 
up the pollen, and there would be no corn on the stalks, while the blades 
and stalks were still green until fall.” W. S. Cook.* 
1889, July 14 to 19, Kansas, Lane County “ Hot winds on 16th and 17th 
from 10 a. m. to 5.30 p. m. each day—direction, southwest—drying up all 
vegetation.”* 
1889, July 14 to 19, Kansas, Comanche County.— 11 Hot southwest winds on 
the 16th and 17th, ceasing about 5 p. m. each day. Nearly all vegetation 
considerably distressed. Corn beginning to tassel suffered most.”* 
1889, July 14 to 19, Kansas, Stafford County. —“Hot winds on 17th—9 
a. m. to 5 p. m; direction, southwest.”* 
1889, July 14 to 19, Kansas „ Grant County. —“ Hot winds from morning 
until evening on the 16th, 17th, and 18th ; direction, southwest.”* 
1889, July 14 to 19, Kansas, Trego County. —“ Hot winds, 10 a. m. to 5 
p. m., on the 16th and 17th; direction, southwest. Corn badly withered. 
We think that the hot winds are generated from the soil by the sun’s 
rays, as the waves of heat strike the face from the earth similar to open¬ 
ing the oven door of a hot stove.”* 
This period of hot winds accompanied an area of low 
pressure which appeared over northern Montana on July 
13 and 14 and moved southeastward, covering the eastern 
slope on the 16th and 17th, with its greatest depth over Ne¬ 
braska, after which it moved rapidly to the northeast, reaching 
Lake Michigan on the morning of the 18th. During the 
movement of the low pressure along the eastern slope the 
barometer was about 30 inches along the coast of Oregon 
and Washington, with generally cloudy weather, and the 
general tendency of the atmosphere appeared to be eastward 
across the divide toward the area of low pressure. Cloudless 
weather prevailed over the central slope on the 16th and 
17th, while it was cloudy and raining to the east and north.
