Rivers Floating Logs to the Mill. 63 



Logs Floating down a Stream. 



1 5. As soon as the snow is melted and the 

 streams are full, so that they have plenty of 

 water to float them, the wood-choppers roll the 

 logs into the stream, and away they go, helter- 

 skelter, until they are stopped by a " boom " or 

 stout log that is fastened there for that pur- 

 pose. Then, one by one, they are dragged into 

 the saw-mill, which gets all its power (either 

 steam or water-power) from the same water that 

 brought down the logs. 



1 6. When a log is fixed securely in its place, 

 the big saw begins to saw it up into boards. 

 Sometimes what is called a " gang-saw " is set 

 to work, which cuts up a log at once into good 

 boards or planks. 



17. A gang-saw is a frame full of saws set just the 

 width of a board apart. For what are boards and planks 

 used?
