Report on the Practice of Ensilage, 
of two sliding doors, which can be removed so as to dean or repair the knives 
or box. Another sliding door is placed on the opposite side, to facilitate the 
unmounting of the knives ; finally, an opening at the bottom serves to empty 
the drum. 
The upper part of the box and the conductor are so made as to be removed 
with ease. The latter is moveable, so as to shoot the fodder at variable 
heights, according to those of the carts, where it is wished to place it. It 
can also be made shorter or longer. The machine possesses a lever for 
throwing the motive band out of gear. It is provided with a wooden sabot, 
acting as a brake on the pulley, so as to stop almost directly the fly-wheel, 
whose ordinary speed is from 300 to 400 revolutions a minute. 
To the foregoing technical description of the makers I add 
the following from my own observation at Cercay : — 
The general appearance and method of using this machine 
are clearly shown in Fig. 16, in which the steam-engine is seen 
to be driving what is in reality a large chaff-cutter enclosed in 
a box furnished with a spout, through which the chopped 
materials are projected into a silo or barn, as the case may be. 
From the roof of that structure flap-boards are hung, and as 
these are brought into use, either by altering the inclination of 
the spout, or by bracing up one or more of the flap-boards, so 
the chopped material can be distributed at pleasure.
