TABLE XXV. CUBIC CONTENT OF ROUND STACKS. 417 



that have stood 10 or 12 months, may weigh 9, 10, or 11 stones 

 per cubic yard, according to size and quality. 



According to Baildon, the quantity of corn in a stack may be 

 estimated at the average quantity of a bushel to a solid yard ; 

 but if the crop has been mown, a yard will not average more 

 than 3 pecks. Stacks of straw may be estimated at the rate of 

 18 or 20 yards to a ton. 



In order to find the weight of stacks, of all the varieties 

 alluded to above, it was considered most advisable to give, first, 

 Tables showing the cubic content of stacks in solid yards and 

 feet, as has been done in this Table, and in Table XXVI., for 

 measuring stacks of an oblong form, and then to give a separate 

 Table, showing the number of stones in any number of cubic 

 yards, ranging from 4 to 20 stones per cubic yard, as is done in 

 Table XX VI I. 



If we suppose the foregoing example to be an old hay stack, 

 and may weigh 16 stones Imperial per cubic yard ; on turning 

 to Table XXVII. we find that 156 yards will be 2496 stones, 

 at that rate. If the hay is supposed to weigh 9 stones Scotcji 

 Trone weight, 156 yards will weigh H04 Trone stones.
