Mr. George S. Hudson arg 
countershaft, two separate actions are com- 
municated—viz., a slow revolving action fifteen 
times a minute to the cylinder, in the interior 
of which six wooden sticks or spindles are 
geared to revolve at the rate of 360 times a 
minute. The writer purchased one of these 
machines from the makers, Messrs. J. Gordon 
and Son, London, for £40, but owing to un- 
satisfactory workmanship and materials great 
difficulty was at first experienced with this 
machine, which is unfortunate, for Mr. Malins- 
Smith’s invention is a very simple and good 
one. However, by employing a more powerful 
engine’ and running the machine constantly, 
either empty or with small loads of cacao, the 
working has gradually become easier and is now 
satisfactory. A single machine at ‘“ Diamond ” 
Estate, Grenada, handles easily a crop of 
1,100 bags. The choice of a good oil engine 
of suitable horse-power is half the battle with 
these machines, and the advice of the inventor 
(Mr. W. M. Malins-Smith, Grenada) should be 
taken on this point. Contrary to what one 
might expect with rapidly moving parts, there 
is less crushing of seed with machine polishers 
than by the old-fashioned foot method. 
The Barnard machine, invented by Mr. 
George Barnard, of St. Lace, consists of a 
slowly. revolving iron cylinder in the lower half 
1 Insufficient horse-power was the trouble throughout,
