106 Report on the Miscellaneous Implemenis 
set of plough-tackle of 14-horse power — which, if correct, gives 
a good idea of the probable difference in coat, both as to capital 
and daily expenditure in the two systems. 
The engine was easily run backwards over the headland 
right up to the fence, aud commenced digging from that point. 
It was also set to dig across that portion of the ground which 
had already been disturbed, and this it accomplished without 
difficulty, the land roller, previously alluded to, helping mate- 
rially to support the weight of the implement. 
It must be said that the agricultural Judges spoke a little 
doubtfully about the condition in which the soil was left by 
both these machines, as compared with the plough, on clover- 
ley or old seeds ; but, supposing the work, generally, can be 
done in a satisfactory manner from the agricultural point of 
view, the Digger may form a valuable farm implement, more 
handy to use, more economical to work, and cheaper in first 
cost than a double-engine ploughing set. It is a case in which, 
looking at the importance of the question, and the advance 
which has been made since steam-digging was first advocated, a 
thoroughly exhaustive trial, in which the Digger is pitted against 
steam tackle, might yield fruitful results. 
IV. Miscellaneous Implements. 
{Arranged in Order of Imj)lement Catalogue.) 
Messrs. Piclisley, Sims, & Co., of Bedford Foundry, Leigh, 
Lancashire, showed a Potato Raiser (Art. 533), which is a new 
implement, not as yet tried, designed for the purpose of digging 
and screening potatoes. It consists of a revolving screen of 
tapering form, about 2 feet in its larger and 1 foot in its smaller 
diameter, and 3 feet long, made of a single wii'e about f inch 
diameter wound spirally throughout the length of the screen. 
The mesh of the wire is close enough to prevent potatoes from 
falling through, while it is open enough to allow of the soil 
escaping. 
The lower and larger end of the screen is armed with half 
a dozen digging blades, which can be raised and lowered by 
means of a lever, so as to penetrate more or less deeply into the 
soil. The potatoes, as they are unearthed by the blades, are 
taken charge of by a peripheral "Archimedean" screw, running, 
internally, from end to end of the revolving screen, and serving 
to discharge the tubers from its smaller end into a hamper 
carried on the machine for their reception. 
The machine is mounted on four travelling wheels, of which 
the hinder pair carry all the weight, the front wheels being
