It will be seen that varying quantities of seed can be sown 
according as the pinion is engaged with the larger, medium, or 
smaller driving-gear, an adjustment which can be instantly 
effected by moving the lever rod which terminates between the 
stilts. The cut-off is of metal and acts in precisely the same 
way as in the ordinary planters, except that it is constantly re- 
volving, and generally deposits the seed at closer intervals. The 
runner is made of cast steel, and iron is largely introduced in the 
frame. The wheel, having a broad rim, covers the seed, breaking 
clods very well. This drill is suitable for small occupations. 
Messrs. Nash and Brothers, of Church Street, New York, exhi- 
bited a Potato Planter and Slicer, which deserves notice for sim- 
plicity of design and novelty of idea. The machine consists of 
a frame on two wheels, carrying a round hopper for the seed 
and a smaller receptacle of similar shape behind for artificial 
manure. The bottom of the hopper has one portion open, over 
this opening is fixed a horizontal knife in such a position as to 
secure a wedge-shaped cut, varying from |- to ^ inch. Above 
the fixed bottom is a revolving plate, filling all the space and 
provided with eight circular openings, any of which can be 
covered if desired. These holes are 4 inches in diameter, but can 
be reduced by bushing-rings to 2£ inches in diameter. Sup- 
posing that all the openings were uncovered, then slices of the 
potatoes are dropped at intervals of 9 inches. The machine is 
most suitable for round sets, which should be tolerably uniform 
in size. A set fills the opening and remains until sliced away ; 
each slice, being wedge-shaped, will possess a portion of skin. 
There is a great saving of seed by the use of such a machine,
