 is the method the Indians used for making a fire. Let the 

 pupils try to make a fire in this way. Make a fire drill in 

 the manual training room.

may ^ e ma ^e by fitting a round piece of wood, 

 eight inches long, into cone-shaped holes bored partly 

 through two blocks of wood, as shown in the cut. The 

 heavy string of a bow is wrapped around the upright, 

 which is made to revolve rapidly as the bow is drawn 

 back and forth. The bearing in the upper block may 

 be greased to prevent friction, but the lower one is left 

 dry. Downward pressure on the upper block will

 the pupils can produce sufficient heat to color the wood 

 an d ma ke it smoke, if they cannot make it burn. 

 Indians produce fire in this way.
