The formula worked out by the Bureau of 

 Plant Industry of the TJ. S. Department of Agri- 

 culture is given as follows : 



0.225 (O— W) OWL-=-H. Q is the dis- 

 tance over the stack; W is the width; L the 

 length, and H the height. First, substract the 

 width from the distance over ; then multiply by 

 the distance over; this by the width, and this 

 product by the length, and this whole product by 

 the fraction 0.225, and divide the result by the 

 height of the stack. All the measurements must 

 be in feet and fractions of a foot. Working out 

 the problem in this way gives the total number 

 of cubic feet in the stack. 



It is claimed that this rule gives results 

 with not more than from two to foiir per cent, 

 error. The number of cubic feet making a ton 

 of hay is divided into the total number of cubic 

 feet in the stack to determine the number of 

 tons. 



NTTMBEB OF 

 CUBIC FEET 

 IIT A TON 



The cubic feet of hay making a ton will vary 

 with the amount of time the hay has settled, 

 with the kind of hay, with the amount of moist- 

 ure it contains, with the weather and various 

 other factors. It is generally conceded that 500 

 cubic feet of well pressed timothy hay is re- 

 quired to make a ton. When the timothy is first
