ing of August 9, moved northward and eastward to South 
Dakota by the 13th, and then moved back southward 
into western Kansas during the 14th and 15th, after which 
it moved slowly to the eastward. During this time the 
barometer stood near 30 inches over western portions of 
Oregon and Washington, with some cloudiness and rain. 
While the general movement of the atmosphere was not 
very well defined, its tendency was eastward across the di¬ 
vide toward the low pressure area. Cloudless weather pre¬ 
vailed during this time over the central and southeastern 
slopes. 
1887, July, Wellington, Kansas. —“ The effects of the temperature during 
this month (July), in connection with hot winds which occurred on the 
13th, 17th, and 27th, 28th, and 29th, with an average duration each day 
of two and one-half hours, caused to some extent in some localities on 
upland farms entire destruction of the corn crop; precipitation, 3.45 
inches, which is .69 of an inch below the nine years’ average.” John H. 
Wolfe, voluntary observer. 
1887, July, Independence, Kansas. —“ We never saw corn wilt so rapidly 
as during the hot waves of the 16th and the 25th to the close of the 
month. The rainfall of 3.21 inches is only .93 of an inch below the July 
average for fourteen years.” J. M. Altafer, voluntary observer. 
1887, July, Bellville, Kansas. —“ On the 29th, from 1 p. m. till 5 p. hi., 
the thermometer stood at 106°, with a hot southwest wind blowing, dam¬ 
aging crops to a considerable extent.” A. B. Graves, voluntary observer. 
1887, July, Brownsville, Nebraska. —‘ ‘On the 29th the temperature reached 
106°, with brisk south wind, hot as the breath of a furnace. Corn and 
all vegetation are about burned up; grass dead. Corn blades are dead 
from three feet upward on the stalks and the shuck appears frost-bitten. 
In the main, corn on the low land is yet good. Apples are baked on the 
trees in some instances. On the 29th, 6 p. m., a thin film of cloud ap¬ 
peared in the northwest and moving in a northwesterly direction. ’ ’ 
George D. Carrington, voluntary observer. 
1887, July, Topeka, Kansas. —Hot winds last of July. 
1887, July, Mercer County, Missouri. —Hot southwest winds July 29th. 
The period of hot winds from the 13th to the 16th ac¬ 
companied an area of low pressure which first appeared 
over eastern Montana on the morning of July 13, moved 
eastward and southward, and was central over western Ne¬ 
braska on the 15th. On the 16th it moved northeast to 
41—Bull. Phil. Soc., Wash., Vol. 12.
