This table will be found not only curious and interesting, but bighly 

 useful, both at the present time and in the future. It will aid engineers 

 in calculating the value of water powers, the flowage of rivers, and the 

 proper size of bridges, culverts and drains. It shows to the farmer and 

 the emigrant that in Wisconsin the rain is well distributed, not only over 

 the several months and seasons, but through the different years. The 

 general mean annual quantity is 30.278 inches, varying from 20.54 in 1845 

 to 44.86 in 1858; the greatest amount in one month was 9.03 inches in 

 August, 1850, and the least one-tenth of an inch in January, 1857. The 

 most rain, on an average, falls in June, the least in February.
