and Miscellaneous Implements at Bristol. 125 
James Smyth and Sons, Peasenhall, Essex, have made im- 
portant improvements in their Corn Drill, which may be shortly 
described. The object in view has been (1) to obviate the 
necessity of removing the seed-cups or hoppers in the seed-box, 
and thus to facilitate the removal of the spindle, as well as avoid 
the breakages which sometimes occur in consequence of the im- 
perfect refixing of the hoppers ; (2) to provide such a change of 
gear, without alteration of wheels, as will compensate for dif- 
ference of pace caused by travelling up instead of down hill, or 
the reverse.

Fig. 31 is an elevation of the seed-box, with its cup-barrel and wooden 
hoppers. 
a is the upper chamber of the seed-box. 
d d, the discs which carry the cups e e. 
ff, the cup-wheel spindle. 
gg, the receiving hoppers through which the seed passes to the conductor, 
h, attached to the underside of the seed-box. 
The forward part of the hopper extends upwards to the level of the top of 
the cup- wheel spindle, and the rear part up to the level of the under side of the 
said spindle. 
k I are two plates attached to the rear of the hopper by the joints m m. 
The plate k inclines towards the cup-wheel d d, so that the seeds fall upon 
it and descend to the hopper g.
