FELLING AXD COXVERSION. 



some other countries, each species of wood, such as heech-loi^s. 

 oak-lo^s, &c., receive differeut series of numhers. 



The numheriD<; may be done by hand, by means of a piece of 

 softwood charcoiil, a red pencil or by Faber's numberinj^ chalk, 

 the marks of which last for two years, A paint brush and black 

 oil-paint mayalso be used with or without stencil-plates. Certain 

 steel dies have also been invented, of which Gohler's revolving 



die-hammer (ti^. 157) is most eftective and at present exten- 

 sively used. According to Iv. Hess, it is less laborious to 

 number the lots by hand, but the figures impressed by the 

 apparatus are more durable and legible, and witli Gohler's revolv- 

 ing hammer 2,000 to 3,000 logs may be numbered in a day. 



Fi.;. ]:.S. 



Another revolving hammer by Sedelmayr, somewhat heavier 

 than that by Gohler, is shown in fig. 158. Logs and blocks are 

 usually numbered 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 stacl\. 

 The numbers slionld be always plainly visible from a road, and 

 so arranged consecutively that any numbered lot may be readily 

 found. The numbering must be done as soon as work on the 

 felling-area is over. 



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.
