: NUMBER OF CUBIC FEET PER TON 
So far as the writer is able to ascertain, the num- 
ber of cubic feet of hay in a ton has been investigated 
very little. He is now measuring the volume of a 
large number of ricks, stacks, and mows, the hay 
from which is to be baled. It is hoped that these data 
may furnish a basis for determining the volume of a 
ton of hay with some degree of accuracy. Until the 
weight corresponding to the volumes measured are 
known, no reliable figures can be given. The prob- 
lem is so complex that no such satisfactory rule for 
estimating the number of cubic feet in a ton may be 
found as is given above for finding the volume of a 
rick of hay. 
The volume of a ton of hay depends on several 
factors. A stack that has stood four months is much 
denser than one freshly built. Hence the length of 
time a stack has stood determines, to some extent, the 
number of cubic feet in a ton of the hay. Also a tall 
stack settles more than a low one. The kind of hay 
also has much to do with it. Clover hay is lighter 
than timothy, volume for volume, and hay with stiff 
weed stems in it does not settle down as compa¢tly as 
hay with no weeds in it. It is common to consider 
512 cubic feet (an 8-foot cube) as a ton in hay stacked 
only a few days, while 350 to 380 cubic feet of hay 
that has stood two months or more will usually make 
aton. In developing rules for estimating the number 
of cubic feet in a ton of hay, the points to be deter- 
wined are (1) the rate at which hay settles after stack-
