BARKING 311 



No general rule can be laid down, as so much depends 

 upon the distance away at which the tannery is situated. 



The following instance will show an advantage in 

 barking : 



If winter felled : 



150 cub. ft. of timber at is. 6d. . . . . 11 5 o

This shows a gain of i, os. gd. on 150 cubic feet of 

 timber, which equals a gain of ifd. per foot by barking. 



But, as the winter felled Oak will often be worth an

EXTRACTION AND TRANSPORTATION OP TIMBER. 



As already stated, the timber must almost always be 

 dragged out from where it is growing on to the rides, where 

 it can be loaded up. There is often a great waste of horse 

 power in doing this. Quite small logs may be pulled out 

 without any particular device being resorted to ; but, for 

 large poles, a dragging shoe or sledge should be put under 

 the forward end of each tree, and thus it will easily ride over 

 the ground. For large trees, where the ground is always 

 more open, a pair of " tushing " wheels, sometimes known as a 

 timber "bob" or "janker," may be used. By this means 

 the heavy end of the log is raised up off the ground, and
