A MIXING MACHINE.
Run by steam Power and Milks Fonr
Cows at Once.

A marvellous milking machine invent
ed by "A Scotehman was shown at the
last Darlington fair in England. 1t is
tailed the Thistle machine. 1t Is made
In both steam and hand power slzes An
English paper describes tho machine as
follow:

The teat cup is by far tho most in

the size of an ordinary winegla arc
made of flexible india rubber and arc
adapted to any cow.
The four cups join Mt the bottom,
with tube attached long enough to
carry the milk to the glass cylinder or
trap on the top of the pail Another
tube connects this glass trap with the
exhaust pipe running overhead When

do when the hand closes ON the teat in
the act Of milking, the momentary in
terval between each stroke being exactly
the same.
BY aid Of the glass receiver the attend
ant is enabled To see when tho milk
ceases to flow and then removes the
cups at once. Should the suction go on,
how ever, after the mi Tx ceases to flow,
no injury Will be done. This has been
fully horne out by practical experiment.
It. is also worthy of note that the milk
" froths" up in tho pail just the same as
