Miscellaneous Implements Exhibited at Bristol , 1913. 263 
is the function of the second disc revolving alongside, for 
when starting both discs revolve until all the fingers have 
seized potatoes, when the second one stops till such time as the 
finger and thumb of the continually revolving disc is empty 
when it comes to proper point of release about 2 o’clock, then 
the finger being closed on what is the thumb, catches the 
second or stand-by disc and revolves it one-sixth of a turn, 
and makes it drop a potato in place of the one that missed. 
Wheels following behind cover over the planted potatoes. 
The mechanism is ingenious, but an extended trial would be 
necessary to say if it were satisfactory in every way. It would 
appear to be a step in the right direction towards labour saving. 
Stand 96, H. Hartjen & Co., Noble Street, London, have a 
well-made Knapsack Sprayer with a double nozzle for potatoes. 
There is nothing remarkable except general good design 
in any of the exhibits until we come to Stand 267, No. 3409, 
a Motor Horse Box, shown by William Vincent, 76, Castle 
Street, Reading. No doubt this vehicle would do the work 
properly and convey two horses at 20 miles per hour, but there 
can be a very limited market for such a vehicle, and one 
would think that the vibration and .shaking going along an 
ordinary road would be almost as bad as a jog home taken 
quietly. Certainly the details are well worked out, but one 
misses the provision for making tea for the rider and gruel for 
the horses. Water could easily be boiled from the engine 
exhaust if required. 
Stand 269, No. 3414, John Fowler & Co. (Leeds), Ltd. Motor 
Plough — Anything exhibited by this pioneer firm deserves 
attention. It is doubtful, however, whether this exhibit shows 
a step in the right direction. The implement consists of a long 
frame carrying an oil engine at one end, and a single or two 
furrow plough at the other, beyond them again there is a pair 
of handles like an ordinary plough for the purpose of guiding 
the whole implement. There are two large carrying and driv- 
ing wheels situated between the engine and the plough. These 
can be adjusted separately for height so that one runs in the 
furrow and one on top, or to go along the road they are at equal 
height. The whole control is by the man guiding the plough. 
It may with justice be objected that it would require a very 
skilled man indeed to walk behind the ploughs, control the 
engine, adjust the height of the wheels, and guide the machine 
all at once ; besides, the tendency now is, if you are to have a 
machine instead of horses let it do as much work as possible 
with ease to the driver, and not just somewhat more than horses 
can do ; and don’t compel your driver to walk, thus limiting 
the output of the machine to the physical powers of the man 
in charge.
