FELLING AND CONVERSION OF TIMBER. 



revolving die-hammer (Fig. 184) is most effective and is 

 now extensively used. According to B. Hess, it is less 

 laborious to number the lots by hand, but the figures im- 

 pressed by the apparatus are more durable and legible, and 

 with Gohler's revolving hammer, used with both hands and 

 marking the figures horizontally, 2,000 to 3,000 logs may be 

 numbered in a day. Another revolving hammer by Sedelmayr, 

 somewhat heavier than that by Gohler, is shown in Fig 185. 

 This marks the figures vertically on the log. 



Logs and blocks are numbered usually at their ends ; in the 

 case of split wood, one large billet is pulled forward from the 

 stack to receive the number ; stacks of poles and smaller

produce and faggots are numbered on a stake driven into the 

 ground in front of the stack. The numbers should be always 

 plainly visible from a road and so arranged consecutively,

After completing the numbering, the estimation of material 

 is made, the forest-manager entering each numbered lot with 

 notes as to its quality in his range timber receipt-book. 



It is usual to have separate books for timber and firewood. 

 The range timber receipt-book should contain the following 

 columns for each assortment of produce :
