aud 10^ In. tliick. The s^pokes are 2^ In. broad, and 1| In. 

 thick ; the fellies 4 In. broad, and 1^ In. thick ; the iron 

 rims I In. thick. As to a third wheel, it cannot be necessary 

 for a machine of the small size, nor for such trees as are 

 removed by it. 



The weight of this machine, with its wheels, is about 5^ 

 cwt. avoirdupois. 



The above machine, it will be perceived, is far less weighty 

 than the foregoing. It is capable of removing subjects of 

 from eighteen to about eight-and-twenty feet high, and of 

 proportional girth ; and in fact, a good part of my trans- 

 planted trees have been removed by means of this light and 

 efficient implement. 



MACHINE OF THE INTERMEDIATE SIZE. 



The pole of this machine is 13^ feet long, including the 

 iron ring at the point, 3^ inches broad, and 5 In. thick, 

 tapering to 3 In. at top. This ring is for receiving the pole- 

 rope, and is 4 In. in diameter. At the top there is a bend 

 3 In. off the straight, in order to prevent any chafing of the 

 bark by the ring. Under the point of the pole, close to the 

 ring, there is a small iron block 3^ In. square. It is rounded 

 at the edges, and well steeled for defending the point of the 

 pole, when trailing along the ground, and so formed as to 

 withstand the friction, and cause little or no injury to the 

 surface. There is also on one side of the pole a plate of 

 iron, extending from within 18 In. of the axle nearly to the 

 top for the purpose of strengthening the pole. It is 2 In. 

 broad, and \ In. thick, and is sunk into the wood. This, in 

 order to give greater power, should be in one piece. 



The iron axle is 4 F. 9 In. long between the washers, 

 and 2i In. square, with a curve in the centre of 2 In., for 

 the sake of greater strength. The wooden cover, or axle- 

 bed, is 4 F. 8 In. long, and 5 In. square, covering the iron
