evenly before entering the threshing drum. These oscillating 
forks are readily adjustable to suit various descriptions of grain. 
By the use of this machine greater regulai’ity is ensured in the 
distribution of the grain to the drum, and enables the work to 
be done at a higher speed, while the machine meets all require- 
ments of a drum guard as a prevention against accidents. As 
will be seen from the diagram, the arrangement is simple, and 
the conveyor feeder is worked with considerably less gearing 
than most types of feeder, lessening the weight of the machine, 
and reducing the cost of repairs and upkeep. The extra cost 
of a conveyor feeder, fitted to a threshing machine, is 15Z. 
Articles 3845-6. — Vacca, Ltd.., 7 Denman Street, S.E. 
“ Milking Machines, manufactured by Messrs. Lawrence and 
Kennedy, of Glasgow, ‘ L. K. 6.,’ suitable for horse gear, steam, 
gas, or oil engine, or electric motor.” — The structural improve- 
ments in these machines entitle them to be considered as 
“New Implements,” and the inventors claim that all the 
objections present in the earlier milking machines are now 
surmounted. The machine consists of a small portable pulsator, 
which is fixed on the milk pail, and connected to the teats of 
the cow by cups at the end of flexible tubes. By another flexible 
connection the pail communicates with a vacuum pipe, and 
an air exhaust, by which the pulsators are actuated. In the 
machine exhibited the pulsating parts are simplified, and there 
are numerous improvements in design ; the vacuum is utilised 
for the threefold purpose of holding the cups on the teats, 
producing suction, and operating the mechanism giving the 
compressing movement. 
Article 4712 . — The Hartnett Patent Milking Machine Co., 
Ltd., 20 High Holborn, W.C. “ Milking Machine, Hartnett’s 
Patent.” Price, exclusive of motor power, 38Z. — The Hartnett 
machine works by means of a double vacuum, combining the 
compression of the teats and the suction for drawing away 
the milk. A peculiar and ingenious feature of the apparatus 
is that the cups automatically release themselves when the 
animal has ceased to give milk. This is effected by the destruc- 
tion of the vacuum, brought about by the apparatus. Another 
point in the favour of this machine is that the pulsator, instead 
of being attached to the milk can, is fixed over head, out of 
reach of the animals. 
It was impossible for the Judges, in the short time at their 
disposal, to express any practical opinion upon these milking 
machines, as this would necessitate a most exhaustive trial, to 
ascertain whether, in their present state, they could be recom- 
mended for use in large dairies. There is, however, no doubt 
that if the milking machine is found to be practicable, it will 
solve one of the great difficulties of the present time, which
