steam jacketed worm chamber, the end of which has suitably 
shaped holes through which the compressed meal is forced, and 
cut off into suitable lengths by a revolving cutter, like a gigantic 
sausage machine. 
On Stand 51, No. 377, Messrs. Robert Boby, Ltd., was shown a 
system of Pneumatic Transport for grain. The action is simply 
that of a vacuum cleaner. A rotary or other pump sucks a 
current of air carrying the grain with it along the pipe to its 
destination, the feeding end having a flexible pipe attached so 
as to be readily plunged into the mass of the grain. There is an 
ingenious arrangement for switching from one pipe to another, 
and for sealing the delivery end so that the air does not leak 
through the wrong way. One would like to know whether 
the dust and dirt that must be knocked off the grain in its 
passage through the pipes is in practice returned to the bulk 
of the grain so as to keep up the Aveight. 
Stand 87, No. 692, F. W. Moellenkamp & Co., 85, Farring- 
don Street, London, E.C. This is a potato planting machine 
made in Germany. It plants two or four rows. Taking one 
row the action is as follows : — 
Two discs running side by side are furnished with six sets 
of catches each, like a finger and thumb. Suppose the discs 
which are some 2 ft. in diameter are revolving clockAvise the 
hopper for the potatoes is say at 8 o’clock, the finger and 
thumb opened passes upwards through a layer of potatoes, 
the catch is released and a potato is almost sure to be caught 
and carried round. To make the “ almost sure ” “ quite sure ”
