AUGUST. 



August, like July, was deficient in temperature and too cool for the 

 proper development of corn and at the close of the month much of the 

 crop had not advanced beyond the roasting-ear stage. The deficiency was 

 quite uniform over each division though the range varied greatly along 

 the Mississippi. The usual hot periods were absent and the temperature 

 was above normal for but short intervals and the hottest weather occurred 

 during the first ten days. At a number of stations in each division the 

 maximum temperature did not reach 90°. 



The precipitation, while averaging slightly below normal, was very 

 unevenly distributed. A large number of stations over the northern di- 

 vision and a few in the central and southern had a decided excess of pre- 

 cipitation and many stations that were decidedly deficient in July, par- 

 ticularly in the southeastern and southwestern portions of the State, 

 showed a pronounced deficiency with drouth becoming serious at the 

 close of the month. The heavy rains of the 19th-20th caused serious loss 

 to crops in Carroll, Greene, Humboldt and Hancock Counties. Hail dam- 

 age occurred principally on the 6th and 8th in Plymouth, Union, Ringgold, 

 Jasper, Iowa, Allamakee, Clayton, Linn, Johnson and Des Moines Counties. 

 The worst storm occurred in Ringgold County, the loss to growing crops 

 in about 25 sections in Lots Creek, Middle Park and Poe Townships 

 amounted to from 25 to more than 50 per cent. The damage was extensive 

 also in Allamakee County over the northeast corner of Iowa Township. A 

 very heavy downpour of rain occurred in Carroll and Greene Counties 

 between Scranton and Glidden, amounting to 5 inches in from two to 

 three hours, causing small streams to get out of banks and doing great 

 damage to bridges and culverts. The loss to bridges and culverts is 

 estimated at $10,000 in each county and the loss to crops probably as great. 



Pressure. The mean pressure (reduced to sea level) for the State was 

 30.02 inches. The highest recorded was 30.37 inches at Dubuque, on the 

 23d, and the lowest was 29.56 inches at Sioux City on the 28th. The 

 monthly range was 0.81 of an inch. 



Temperature. The mean temperature for the State, as shown by the 

 records of 105 stations, was 69.3°, or 2.5° lower than the normal. By di- 

 visions, three tiers of counties to the division, the means were as follows: 

 Northern, 67.7°, or 2.7° lower than the normal; Central, 69.4°, or 2.3° 

 lower than the normal; Southern, 70.7°, or 2.5° lower than the normal. 

 The highest monthly mean was 73.4° at Burlington and Keokuk, and the 

 lowest was 65.4°, at Decorah and Spencer. The highest temperature 

 recorded was 98° at Monroe on the 5th and Clarinda on the 10th, and the 

 lowest was 39° at Decorah and Stockport, on the 24th. The temperature 

 range for the State was 59°. 



Precipitation. The average precipitation for the State, as shown by the 

 records of 109 stations, was 3.35 inches, or 0.33 inch less than the normal. 

 By divisions the averages were as follows: Northern, 3.98 inches, or 0.50 

 inch more than the normal; Central, 3.41 inches, or 0.36 inch less than the 

 normal; Southern, 2.67 inches, or 1.11 inches less than the normal. The
