AA is the pole, BB is the bar of iron, C is the coupling by 

 which the lever is fixed to a tree, stake, or other holdfast ; D and 

 E are the pulling chains, and F and G are the clasps by which the 

 iron is fixed to the wood, the butt end of the pole being flattened 

 for their reception. 



When a tree or other object is to be moved, a standing tree is 

 selected, or a strong post is fixed into the ground, to act as a hold- 

 fast or fulcrum ; round this a chain is passed, and the lever is 

 attached by its coupling (C) about 3 feet from the holdfast. From 

 10 to 20 yards from the object to be hauled is a good distance 

 at which to fix the lever, but a longer distance will answer the

 that it is worked horizontally. 



The lever being fixed, the next operation is to 4ay down a line 

 of chains to the object to be moved, one end being made fast 

 thereto, and the other, after the whole has been pulled as tight as 

 possible by hand, being coupled to the lever (Fig. 2). This 

 being done, everything is ready for pulling. 



To accomplish this, one man attends to the hooks, while three
