Rivers. Though many heavy rains occurred, beginning the 17th, the rate 

 at which they fell was generally slow, and as the ground was very dry from 

 more than a month of drouth, little of the rain reached the streams as a 

 rule till the 30th, and no large rises in the streams had occurred up to the 

 close of the month.The largest rise was 3.9 feet at Van Meter on the Rac- 

 coon in the five-day period ending the 22d. This rise was quite noticeable at 

 Ottumwa on the Des Moines, where it amounted to 3.3 feet in the four-day 

 period ending on the 22d. On the Mississippi and Missouri Rivers rather 

 low. stages prevailed.
