7.9S' inches fell between 6 p. m. of the 28th and 7 a. m. of the 29th. At sev- 

 eral stations in the central portion of the southern district the total rain- 

 fall for the month was less than half an inch. 



The temperature was very nearly normal; there being a positive depar- 

 ture of only 0.1°. The month as a whole was considered cool although on 

 the 1st, 11th, 12th, 21st and 22d the day temperatures were generally 

 above 90°, and at several stations were up to 100° on the 1st or the 22d. 

 The night temperatures were moderately low during the most of the 

 month; the lowest being on the 26th, when minimum temperatures below 

 40° were recorded at several stations. The lowest temperature reported 

 was 36°, at Plover, "Washta and Woodburn. A trace of frost was observed 

 on the morning of the 26th on low ground in some localities, but no dam- 

 age was done to vegetation. 



The dry weather during the first half of the month was favorable for 

 threshing, but was injurious to pastures, meadows and late potatoes, and 

 in some sections, to corn. Over the northeastern and some of the central 

 and southwestern counties, where the showers did not come at the proper 

 time, corn was injured to some extent, but for the state at large, the crop 

 held its own remarkably well and was in fine condition at the close of 

 the month. The rains during the latter half of the month were very 

 beneficial to pastures, meadows, potatoes and late corn, and at the close 

 of the month the indications were favorable for more than an average 

 yield of corn, in spite of the long continued drought.

 Washta, Cherokee County, and Woodburn, Clarke County, on the 26th. 

 The average monthly maximum was 96°, and the average monthly mini- 

 mum was 43°. The greatest daily range was 47°, at Decorah. Winneshiek
