can be attached to the potato-digging machines now in use. It 
has a revolving screen of large dimensions, which travels upon the 
ground by its central rim. With the rotary digging machine the 
picker is arranged to receive the potatoes as they leave the digger, 
which passes them into the screen. There the dirt and weeds are 
screened out, and guides conduct the potatoes into cups or pockets 
which empty their contents into a basket as the screen revolves. 
The picker can be set nearly to touch the revolving forks of 
the digger, or be easily placed at such reasonable distance 
from them as may be desired. A box with a movable side is 
fitted to carry the basket or sack immediately above ground, if 
it be desired to bag or skep the potatoes ; or the box itself may 
be made removable if it be re- 
quired to carry them into a 
heap at the headland before 
turning 'round. The heap at 
the headland may be made 
large enough to be earthed 
down for the winter. The 
combined machine is balanced 
upon the two driving-wheels of 
the digger, and will back or 
turn within its own length. 
There are no belts, gearing, 
cranks, or cams; and there is 
no side draught or weight up- 
on the horse’s neck or back. 
The frame of the picker is made 
of wood, with wires of gal- 
vanised steel firmly bedded in 
indiarubber, which are easily 
set to any distance apart. The 
entire machine is easy of al- 
It is fitted with shafts and 
horse-tree for a pair of horses abreast, and a third may be 
attached in front of shaft if required. In action it is necessary 
to remove the haulms from the front if they are long, and the 
machine must be worked when the land is dry enough to use 
the ordinary land roller. It will clear the field, in combination 
with the digger, ready for the next crop, and takes one man and 
cwo lads to work three acres per day.
