 Under the point of the pole there is a block of iron, with 

 rounded edges, 3 inches long by 1 inch thick, and well 

 steeled; so that, whenever the point of the pole happens 

 to be trailed along the ground, it may withstand the 

 friction without injuring the surface. There is likewise 

 on one side of the pole a plate of iron, extending from 

 within 18 inches of the axle nearly to the top, for strength- 

 ening the pole. It is 1^ inch broad, i inch thick, and 

 sunk into the wood. This plate, in order to render it 

 more powerful, should be in one piece. 



The iron axle is 4i feet long between the washers, 

 (exclusive of a head at each end. Hi inches long, which

The first stage rises in the centre 2^ inches above the 

 axle-bed, and is firmly bolted to it. It is 4 feet 5 inches 

 long, 4 inches broad, and 3 inches thick. The second

 latter. It is also 4 feet 5 inches long, 9 inches broad,

 the second, and is in the same manner bolted to it. It is
