13. "The northern corn crop will mostly be a failure, and prices will be high a 

 year from now." 



14. "As will be seen by the table, the west third of Kansas will be deficient in rain 

 after June." 



The preceding extracts comprise the principal predictions made by Mr. Blake as 

 deductions from his "Tables." And because a comparison of all his tables with the 

 actual temperatures and pressures would be too great a labor, and since any selec- 

 tion by me of a portion of them might not fairly represent the whole, it seems best 

 to confine the verification to Mr. Blake's own selection from the tables and his pre- 

 dictions based thereon. 



The data used in the work have been obtained from the United States Bureau of 

 Statistics, the Department of Agriculture, the Reports of the State Weather Services, 

 and the Weekly Crop Bulletin and Monthly Weather Review of the Signal Service ; 

 and I am under obligation to the officers of these various Bureaus for their kind as- 

 sistance in furnishing me the necessary material. 



ACTUAL WEATHEE. 



1. "As a whole the snow-falls of January, 1889, have been unusually small.'''' 

 "The mean temperature was generally above the normal over all districts east of the 

 Rocky Mountain regions, except in portions of Florida and Texas." — Monthly 

 Weather Review. 



In Dakota and Minnesota, where the predicted "steady cold weather" would 

 naturally be expected to occur, the mean temperature was from 10° to 15° above the 

 normal. 



2. To test the value of the special prediction of heavy precipitation in the 

 Northwestern States, the following table has been prepared, giving Mr. Blake's pre- 

 dicted precipitation, the normal precipitation for January, and the actual precipi- 

 tation. 



PRECIPITATION IN NORTHWESTERN STATES. 



3. To determine the degree of verification of the third prediction, the following 

 statements as to the precipitation on the Pacific coast for April, May and June have 

 been taken from the Monthly Weather Review: 



"In April, 1889, the precipitation over the whole Pacific coast was below the nor-
