Manuring. — Manure usually was hauled from the barn to the 
field in manure spreaders, either during the winter as available or in 
the spring from the winter's accumulation. Occasionally a grower 
hauled the manure out during the winter with a wagon or sled and 
formed large piles, which were spread in the spring with a spreader. 
In the area of Clay County, Minn., only 33 per cent of the acres planted 
to potatoes were manured and in the area of Aroostook County Me., 
only 37 per cent. In all the other areas more than 75 per cent of the 
acres were manured. Nearly all the manure applied was produced 
on the farm.
