THE SUBJECT CONTINUED. 233 



You may call this "theory," my good Mr. Practi- 

 cal, but I tell you it is TEUTH : simple, obvious, 

 philosophical, practical Truth. Since the invention 

 of the Steam-engine^ it might and may be done at 

 one process ', as easily as before in twenty ; and it 

 will be. Before we depart this life, we shall see 

 one more wonder moving on the face of the earth, 

 something of this form and fashion to wit a 

 complete locomotive engine on four wheels, the fore 

 pair turning on a transome, the hind ones fixed ; 

 behind them (suspended) a transverse, cylindrical 

 shaft, three feet in diameter, from six to eight feet 

 long, reminding one of a cross-breed between a 

 clod-crusher and a hay-tedding machine, armed 

 with case-hardened steel tine-points, in shape like a 

 mole's claw, arranged so that the side-lap of each 

 claw may cover the work of the other, and no 

 interval or ridge be left uncut : the extremities of 

 the cylinder just covering the wheel-tracks. This 

 cylinder of claws you will see raised or depressed 

 at pleasure by the engine-driver, and adjusted to 

 slow or rapid revolutions, worked either by cog- 

 wheels, or geared from the drum of the engine. 

 That is the "cultivator." A platform from the 

 Engine extends over it, ending in a sort of movable 

 tail-board, which may be raised or depressed at
