not be convenient, however it might suit large roots or 

 branches, to make the axle longer than the above dimen- 

 sion, on account of gates, and other narrow passes, through 

 which the machine might be taken, and that seldom 

 exceed 9 or 10 feet wide. The heads of the axle WW 

 are 1 4 inches long, and fitted to the bushes of the wheels. 

 The dust-hoops are 1 inch broad each. The wooden 

 case IK (or, as it is called, the axle-bed) is 6 inches 

 square, covering the iron, 2 inches, and consequently 

 showing only 1 inch of it. To the axle-bed are fixed 

 two strong hooks of iron ZZ, 6i inches long, and strongly 

 bolted to it, to which the horses are attached for drawing 

 the machine. 



The two side-stays PLGL (fig. 1) are made as short as 

 possible, in order to prevent interference with the branches, 

 being 5 feet long, 3i inches broad, and 4 inches deep or 

 thick, and strongly bolted to the axle-bed and pole. The 

 upper stay MN, (fig. 2,) which rests upon the first stage 

 at M, is 5| feet long, 3J inches broad, and 4i inches 

 thick, and is in like manner bolted to the pole. 



The first stage OP (fig. 3) rises 4 inches in the centre 

 above the axle-bed, and is bolted to it. This stage is 5 

 feet 5 inches long, 6 inches broad, and 4 inches thick. 

 The second stage QR rises 6 inches above the first, and 

 is in the same way bolted to the latter. It is also 5 feet 

 5 inches long, 10 inches broad, and 3 inches thick. The 

 third stage ST rises 6 inches above the second. It is 

 only 3 feet 10 inches long, 10 inches broad, and 3 inches 

 thick, and is similarly bolted to the stage last mentioned. 

 The third stage is movable as occasion may require ; and 

 the machine can be used either with or without it, accor- 

 ding to the extent of the roots and branches of the trees 

 to be removed. On the stage which happens to be upper- 

 most there is fixed a firm bolstering of double mat SVT,
