Determining the number of board feet in a log is a matter 

 with which few farmers are familiar. This is determined by 

 established rules and practices among lumbermen. These 

 rules and practices vary in different sections of the country 

 and with different species of logs. The Doyle rule is the com- 

 monly used rule in this state. The logs should be cut about 

 four inches longer than the even feet to allow trimming off 

 weather-checked or broken ends. In the Doyle log table, which 

 follows, the length of the log is given in feet in the top hori- 

 zontal line ; and the diameter, which is always measured inside 

 the bark at the small end of the log, is given in the left-hand 

 vertical column. The contents of the log in board feet is found 

 at the intersection of these columns. For example, a log is 

 16 feet long and 22 inches in diameter inside the bark at the 

 small end. By following down the verticle column under 16 

 until it intersects the horizontal column to the right of 22, we 

 find the number 324. This is the number of board feet of 

 lumber that can be cut from a log of the size given according / 

 to the Doyle rule. The number of board feet in a log of any 

 other .size can be found in like manner.
