536 THE HANDBOOK FOE PRACTICAL FARMERS 



four hundred cubic feet of hay is considered a ton. The actual 



weight of four hundred cubic feet of hay will vary according to 



the quality of the hay, time of cutting, position in the mow, etc. 



For making an estimate in a given case multiply together the 



length, breadth and height of the mow or stack in feet and divide 



the product by four hundred. The quotient will be the number 



of tons.
