 a channel wide enough to enable them to roll the remaining logs 

 from the pile into the stream. After having cleaned up one 

 section they proceed to loosen the next section above, and are 

 sometimes obliged to explode a small charge of dynamite to 

 free the logs which are frozen together. The loose logs float 

 down to the splash dam where they are converged toward the 

 sluiceway by bracket booms. Drivers stationed on the latter

keep the logs parallel to the current and prevent them from 

 jamming when they pass through the sluice. Workmen armed 

 with peavies and pike poles ^ are stationed at strategic points 

 along the stream to prevent logs from becoming stranded on 

 sand bars, and from forming jams on rocks and in narrow places 

 in the channel. 



1 This has an ash or hickory handle, from 12 to 20 feet long, on one end of which 

 is attached a screw pike and hook. It is very serviceable in controlling logs in 

 water. The screw pike when forced into a log has a tenacious grip which enables 

 the workman to exert a strong pull without losing his hold on the log.
