both ends of the table instead of one, and has only half the 
distance to travel. The onward pressure of the screw has a 
tendency to drive the buttermilk in front of it, instead of pressing 
it downwards, and at 
the same time leaves 
behind channels on the 
surface, of the best pos- 
sible form for the butter- 
milk to run down. There 
is less mopping to be 
done, and the roller is 
more easily wiped and 
cleaned. Time, which 
means money, is saved 
here, and it may be 
well to state that the 
, extra cost of the new 
Worker is only about 
two shillings. 
The Dairy Supply 
Co., Limited, for the 
application of a Refrige- 
rator between the Churn 
and the Separator in an 
Instantaneous Butter Maker (Art. 710). This contrivance may 
fairly be described as a wonderful "development of dairy ma- 
chinery, and it is not too much to say that nothing in the Show- 
j'ard attracted more attention. If we had not of late years been 
educated up to it by such a machine as the cream separator, we 
should be the more astonished to see new milk converted into 
the three products, skim milk, butter, and buttermilk, as fast 
as it can run from a tap. 
The entire apparatus consists (Fig. 2) of several parts, viz. — a holder or tub 
for the milk ; a warmer to raise the temperature of the milk before passing into 
the separator, of the ordinary kind ; the separator, driven by a steam turbine 
of improved construction, with one steam outlet instead of two as formerly, 
and which it is claimed takes less power to drive ; a refrigerator, of improved 
construction, with internal diaphragms which cause the whole of the cold 
water to pass close to the inner surface of the metal, over which the cream 
is spread before passing into the churn. The churn is a horizontal cylinder, 
some 12 in. long by 4| in. diameter, outside measurement, with a centre 
spindle carrying straight wire beaters parallel to, and of nearly the same 
length as, the churn. This spindle is driven by a cotton rope belt,from a pulley 
on the separator spindle, at a speed of 3,000 revolutions a minute, or half that 
of the separator. 
In the trial, 250 lb. of milk was weighed, mixed, and put in 
the holder at a temperature of G5°. The separator was started
