cubic feet to the cord. Smooth hard wood yields about the 

 same. 



3. Still smaller round wood, wood that is crooked and 

 knotty, and good split hard wood contains in solid wood 

 about .6 of the outside contents of the pile or 77 cubic feet 

 per cord. 



4. Small, crooked wood cut from limbs may run down 

 as low as 27 solid cubic feet per cord. 



5. 1 The longer a lot of wood is cut, the greater will be 

 the vacant space left in piling. Fair sized pulp wood, for 

 instance, which when cut 4 feet long will measure a cord, 

 if cut in 2-foot lengths will pile up in 2 to 3 per cent less 

 space. The same wood, on the other hand, if cut 8 feet 

 long and measured in the pile will measure nearly 6 per 

 cent more; if 12 feet long, about 12 per cent more. 



Wood in thorough air-drying shrinks about 10 per cent 

 on the average, hard woods as a rule more than soft. If 

 wood checks and cracks freely, something like half the 

 total shrinkage is taken up in this form. Two inches extra 

 height in the pile are commonly allowed on green wood 

 in Massachusetts. 



To Measure Wood in Cords. When the wood is 4 feet 

 long, measure the height and length of the pile in feet, 

 multiply together, and divide by 32. The result will be 

 contents in cords. If the wqod is more or less than 4 feet 

 long, multiply length, width, and height of the pile together, 

 and divide by 128. If wood is piled on sloping ground, 

 the length and height should be measured perpendicular 

 to one another. 



For measurement of logs into cord measure, see page 138. 



The French cord of the Province of Quebec is 8' 6" X 4' 

 X 4' 3", containing, therefore, 144 cubic feet, as against 

 128 for the cord current elsewhere.
