is 4 In. bioad, and 3 In. deep, covering the iron H l^^-j and 

 showing, of course, only 1 In. of it. To the axle-bed are 

 fixed two strong hooks, 4 In. long, to which the horse is at- 

 tached, for drawing the machine. 



The two side-stays are each 3 F. 10 In. long, 2i In. 

 square, and strongly bolted to the pole. The upper stay rests 

 on the first stage, and is 4 F. 4 In. long, 2i broad, and 3 In. 

 thick, tapering to 2i In., and bolted to the pole in like 

 manner. 



The first stage rises in the centre 2i In. above the axle- 

 bed, and is firmly bolted to it. It is 4 F. 5 In. long, 4 In. 

 broad, and 3 In thick. The second stage rises 4i In. above 

 the first, and is bolted to the latter. It is also 4 F. 5 In. long, 

 9 In. broad, and 2 In. thick. The third stage rises 4^ In. 

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

 It is 3 F. 4 In. long, 9 In. broad, and 2 In. thick. The 

 third stage is movable at pleasure, and the machine is used 

 either with or without it, according to the style of the subjects, 

 and of the work. On whichever stage happens to be 

 uppermost there is fixed a bolstering of double mat, filled with 

 hay or straw, 6 In. thick, so that no injury can be sustained 

 by the bark of the stem. 



The blocks between the stages are 9 In. long, 2i In. broad, 

 and 41 In. deep. The end of the upper stay, as it rests on 

 the first stage, shows itself, in the end view (Fig. 3.,) like a 

 block in that situation ; and the end of the pole has the same 

 appearance from the same point, as resting on the axle-bed. 

 — Wherever it can be done, the bolts, used for all of the above 

 purposes, are shown in the diagram. 



SMALL-SIZED WHEELS. 



These wheels are 5 feet high, made of the best materials, 

 nearly upright, and the dishing only 1 inch. 



The naves are 10 In. long, exclusively of the nave bands,
