put into the stack, or if it is too ripe, coarse, or 

 loose, it will take seven hundred cubic feet. For 

 alfalfa which has settled thirty to sixty days, 

 Ave usually figure as a ton a cube eight feet on a 

 side, or 512 cubic feet. For fine native hay or 

 alfalfa that has settled six months or more, a 

 cube seven and one-half feet on a side, or 422 

 cubic feet is considered sufficient for a ton. 

 Some native hay will be found heavier than this. 

 It is probable that the general estimate of 512 

 cubic feet would give but small error for good al- 

 falfa hay.
