excess. Most of the precipitation was in the form of snow or sleet. 

 Glaze covered a large portion of the southern and central divisions on 

 the 3d and 20th making travel on foot difficult and dangerous. 



The month was free from severe storms, the snow that fell drifted 

 less than usual, and at no time during the month was traffic impeded 

 by snow blockades. The snow cover remained on the ground over most 

 of the northern half of the State throughout the month, but over the 

 southern half it began to disappear early in the month and corn husking 

 and grazing were possible generally as the month advanced. During the 

 most severe weather considerable areas were without snow cover in 

 the southern division and wheat is thought to have suffered materially. 

 The roads were better than usual for this season of the year.
