AUGUST. 



On August 4th-5tli high temperature records, covering periods of 40 

 to 46 years at some stations, were broken. The highest reported was 

 113° at Clarinda, Knoxville and Shenandoah on the 4th, which equals the 

 absolute maximum, for the State that occurred at Sigourney on July 22, 

 1901. The monthly mean for the State, 76.0°, though 4.2° above normal, 

 was exceeded in August, 1900, 1909 and 1913. The excess in temperature 

 was greatest, 8.0°, in Adams county where the greatest damage to corn 

 occurred. Precipitation was deficient from the Missouri River eastward 

 over the central counties extending in a narrow belt to the middle Missis- 

 sippi. The deficiency exceeded 3 inches in Monona, Fremont and Webster 

 Counties; and in the extreme southwest counties from March "1 to August 

 31 Is more than 50% of the normal. 



The corn crop had been somewhat injured by drouth prior to August 

 In the southwest one-third of the State and was in poor condition to with- 

 stand the withering heat, strong southerly winds and low humidity which 

 were at a climax August 4-6 and were somewhat damaging in localities 

 till general showers came about the middle of the month. As a whole, 

 the crop deteriorated 11 per cent or about 35,000,000 bushels. In Adams 

 County where the worst damage is reported, the crop will be only 20 per
