Miscellaneous Implements at Reading, 1882, 633 
where the hay-dryers were preparing for work. The crop was 
very heavy ; and the wind at the time blowing half a gale gave 
the machine a severe test ; and although the Judges could see 
considerable merit, they noticed some minor particulars that 
will be required to be altered, and, under these circumstances, 
they would not be justified in doing more than favourably 
mentioning the implement. In a moderate crop, with the 
back motion, the machine would be able to do a large amount 
of work. 
The East Yorkshire Waggon Company offered to the public a 
new Potato Separator (Copeland's patent). By the aid of this 
machine three samples of potatoes are made with one operation. 
As shown in Fig. 11, the machine consists of a revolving 
cylinder made of round bars of iron, differing in width ; 
the first compartment allows only the smallest potatoes to 
escape through, the second compartment taking the medium 
sized, and the best fall out at the opposite end. There is a 
wooden partition placed in the centre of the machine to prevent 
the potatoes coming through too rapidly. The motion is very 
slow, and the power required to work it very slight. The price 
is 6Z. 10s.
