The two side-stays FLGL {Fig. 1.) are made as short as 

 possible, ill order to prevent interference with the branches, 

 being 5 F. long, 3^ In. broad, and 4 In. 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^ F. 

 long, 3^ In. broad, and 4^ In. thick, and is in like manner 

 bolted to the pole. 



The first stage OP (Fig. 3.) rises 4 In. in the centre above 

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

 long, 6 In. broad, and 4 In. thick. The second stage Q.R 

 rises 6 In. above the first, and is in the same way bolted to 

 the latter. It is also 5 F. 5 In. long, 10 In. broad, and 3 In, 

 thick. The third stage ST rises 6 In. above the second. It 

 is only 3 F. 10 In. long, 10 In. broad, and 3 In. 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, according to the extent of 

 the roots and branches of the trees to be removed. On the 

 stage which happens to be uppermost, there is fixed a firm 

 bolstering of double mat SVT, filled with hay or straw, of at 

 least 6 In. in thickness, so that the bark of the stem can sus- 

 tain no injury. 



The blocks UUUUU between these two stages, are 10 In. 

 long, 4 In. broad, and 6 In. high. The end of the upper stay 

 at X (or at M. Fig. 2.,) resting on the first stage, represents, 

 in the end view of the machine, another block in that posi- 

 tion ; and the end of the pole at Y is seen in the same way, 

 and for the same object. Wherever it can be done, the bolts, 

 for the various purposes above mentioned, are shown in the 

 diagram.
