MAY. 



The month was characterized by cool weather during the first and 

 moderately warm weather during the latter half, and by numerous tor- 

 rential rains, although there was a decided deficiency of rainfall for the 

 State, as a whole. The month was, however, unusually favorable for all 

 out-door operations, and farm work progressed rapidly. The bulk of the 

 corn was planted by the 23d, and by the close of the month much of it 

 has been cultivated once and some of it twice. Frost was quite general 

 over the northern two-thirds of the State, between the 12th and 14th, but 

 no damage was done except to tender garden truck. Destructive wind 

 squalls occurred in many localities on the 3d, and on the night of the 

 lOth-llth, which blew down wind-mills, silos and small buildings, and 

 caused the death of one man near Camanche on the 3d. Most of the wind 

 squalls attended severe electrical storms, and were accompanied by ex- 

 cessive rainfall and, in some cases, by hail. The heavy rains caused con- 

 siderable damage by floods and soil erosion, and the hail was destructive 

 to fruits, garden truck, meadows and green houses. The lack of moisture 

 in the southern counties was detrimental to all crops except corn, which 

 was in fine condition and growing rapidly at the close of the month. 



Pressure. — The mean sea-level pressure for the State was 30.06 inches. 

 The highest recorded was 30.46 inches, at Dubuque, on the 15th; the 

 lowest, 29.54 inches, at Sioux City, on the 3d.
