crums. A strong lever, a, is furnish- 

 ed at one end with a thick iron hook 

 (shown in Fig. 54), which is first fast- 

 ened on the root of the stump, and then 

 one of the pins is inserted under the 

 lever. The lever is now elevated, and 

 the other bolt is placed under it. It is 

 next pressed down, and the first bolt 

 elevated one hole higher, and so on tOl 

 the stump is torn out. To prevent the lever slipping, 

 a notch is made in its under side, on each side of the 

 hook, as shown in Fig. 54. 



A more powerful stump-extracting machine, made 

 on precisely the same principle, is exhibited by Fig. 

 55, p. 74. The lever, a, should be a strong stick of 

 timber, furnished with three massive iron hooks, se- 

 cured by bolts passing through, as represented in the 

 figure. Small or truck wheels are placed at each end 

 of the lever, merely for the purpose of moving it easily 

 over the ground. The stump, b, used as a fulcrum, 

 has the chain passing round near its base, while an- 

 other chain passes over the top of the stump, c, to be 

 torn out. A horse is attached to the lever at d, and, 

 moving to e, draws the other end of the lever back-
