Table 36, based on actual measurements of over 73 cords, gives the 

 relation between number of trees, number of sticks, and the solid 

 contents of a stacked cord.

If the middle diameter of the average 4-foot sticks in a stacked 

 cord of wood is known, the solid contents of the cord can be readily 

 ascertained, as it varies with the middle diameter of the average 

 stick in the f oUowing manner :
