get endwise. The geaiing is on the most approved and well-tried principle, 
malledble iron being introduced in place of cast iron where it was found liable 
to breakage. This, together with the improved feed-rollers, has,' enabled the 
makers to dispense with the " safetj' pin " used by most makers, which gives 
constant trouble and annoyance by shearing off and having to be replaced. 
Keeping the knives sharp being most important in working a chaff-cutter, it 
is constructed so that the fly-wheel can be taken off, and another with sharp 
knives put in its place in about two minutes. The knives also cut over a 
hardened steel-faced mouthpiece, and claw feet hold the machine securely in 
position when at work. It is provided with bagging apparatus, and may be 
used in connection with a steam threshing-machine, driven from a pulley on 
the drum shaft, when the straw, falling from the machine shakers on to the 
cutter feed-board, is reduced to short chaff, has the dust blowTi from it, and is 
delivered into bags as fast as it is threshed." 
The foregoing representations of the end and side elevations 
of Messrs. Bust's Special " Ensilage " cutter are thus explained 
by themselves : —

hard substance getting into the machine, a strong sheet-iron shield, g, is 
])laced in the bagging apparatus, so that the force with which it is thrown off 
the vanes is broken and directed downwards into the bag. The cover to the
