TIMBER MEASURING 



below where a big branch has grown out from the main 

 stem. 



The following illustration will explain this : 



Girfhed here 



Thus, in the above case the log is 39 feet long, but there 

 are two stops at " A " and " B." 



Therefore, the first length of 17 feet is taken up to the 

 beginning of the first stop, and at half-way along this length 

 the girth is taken and the quarter girth under bark ascer- 

 tained, viz., 1 8 inches. 



Then a second length of 10 feet to the next stop is 

 taken, and the quarter girth under bark at half-way along is 

 found to be 14 inches. And then the third length of 12 feet 

 is taken, and the quarter girth at half-way along is found to 

 be 7 inches. All these measurements are separately booked, 

 and the contents afterwards worked out in the office by 

 reference to tables. 1 



Occasionally, in order to save time, a measurement is 

 made beyond a stop. But in such cases the greatest judg- 

 ment is necessary ; and, without a great deal of experience, 

 it is never safe to go beyond a stop. 



In the above example, if the log had been taken in one 

 single length, the quarter girth measurement would have 

 been (say) 14 J inches, and the contents would have been 

 computed at nearly 2 cubic feet more than the correct 

 contents. But supposing that the first length of 17 feet had 

 been taken separately ; and that then, the buyer suggested, 

 that the rest of the log should be taken in one length "so as 

 to save time." The vendor would thereby lose considerably, 

 for the girth would come just above the second stop and
