which controls its action. The piston is connected with a lever 
which moves the cutter, the latter being made with several 
teeth, as is usual in clipping machines. A small engine or 
other motive power is required to work the air-compressor, and 
to drive the air into the air-receiver. The air is then conveyed 
by means of tubing (fig. 9) to the shearers, several of which may 
be set in motion simultaneously. Shafting and belting are 
thus rendered unnecessary, thereby making the apparatus more 
portable and more easy to set up than when other kinds of 
shearers are employed. The shearer (figs. 10 and 11) is attached 
to flexible rubber tubing which permits the operator to work in 
any position, and a small tap near to the shearer allows him to 
Fio. It).— General Tiew of Slisarer.

put the machine in or out of gear at will. Although great speed 
is attained, the shearer does not get hot, as the exhaust air keeps 
all parts cool, thus materially increasing its durability. 
It is essentially a machine for working on a large scale, 
and the number of shearers which can be worked at one time is 
practically unlimited, whilst one skilled man is sufficient to over- 
look the operations of a large gang of workers, thereby render- 
ing it unnecessary that all the men should be skilled in the use 
of machinery, and making the machine more valuable, as it is 
sufficient that the men should be able to hold the sheep in a 
proper manner. The wool is cut oft' in an even manner all over 
the sheep, and the skin is neither cut nor braised. Moreover, as 
the sheep is under the hands of the operator for a shorter time
