THE PLANTEB's GUIDE. 



inclies broad, 3J inches thick, and tapering to 2^ inches 

 at the pole, to which it is in like manner bolted. 



The first stage rises in the centre 22 inches, and at the 

 sides 6 inches above the axle-bed, and is bolted to it. 

 The stage is 4 feet 8 inches long, 5 inches broad, and 3i 

 inches thick. The second stage rises 4|- inches above the 

 first, and is bolted to the latter. It is 4 feet 8 inches 

 long, 9 inches broad, and 2i inches thick. The third 

 stage rises 4i inches above the second, and is in the same 

 ■way bolted to it. It is 3 feet 6 inches long, 9 inches 

 broad, and 2 inches thick. The third stage is movable 

 at pleasure, and the machine is used either with or with- 

 out it, according to the magnitude of the subjects to be 

 removed. On the stage, which is uppermost, there is 

 always a strong bolstering of double mat, filled with hay 

 or straw, 6 inches thick, so that the bark of the stem may 

 not be injured by the pressure. 



The blocks between the two uppermost stages are 9 

 inches long, 3 inches broad, and 4^ inches thick — that is, 

 deep. The end of the upper stay, by resting on the first 

 stage, shows itself like a block in the end view of the 

 machine (fig. 3. ;) and the end of the pole presents a 

 similar appearance when seen in the same manner, as it 

 rests upon the axle-bed. Wherever it is possible, the 

 bolts used for all of the above purposes are shown in the 

 diagram.
