TIMBER TRANSPORT. 45 



and along the rails to the end of the main line, 

 where they are rolled off, and laid down in con- 

 tinuation of the line. The scattered logs hav- 

 ing been all removed, begin at the ends of the 

 branch lines, raising the last logs one after the 

 other on to the rails, and rolling them away to 

 the end of the main line, employing them all in 

 their order to lengthen the line, until the river is 

 reached. 



On coming to an incline downwards, the logs 

 would run away, and acquire an impetus that 

 would probably throw them off the line to a 

 considerable distance. To obviate this, place the 

 rails close together down the incline, and turning 

 the travelling logs round endways on coming to 

 this point, slide them along the groove between 

 the pairs of rails. A few short rollers will 

 probably be necessary to slide the log along before 

 it has acquired an impetus, but once set in motion 

 it will glide along rapidly to the foot of the 

 descent. 



If there is an ascent steep enough to render it 

 difficult to roll the log up from behind, take two 

 ropes of 50 to 100 ft. in length, and securing these 

 by means of grappling-hooks firmly driven into the 

 butts of the rails ahead, bring the other ends 

 back under the log and round over (vide the 

 bottom line of rails in the last Plate), when the
