770 The Trials of Cider -malting Plant at Glastonbury. 
The mill consists of a pair of rollers 1 44 in- diameter by 18 in. 
long, constructed of "Pennant" stone, a material which pre- 
serves a rough surface in work. These ran, during the trial, at 
differential speeds of 175 and 350 revolutions per minute re- 
spectively, and were fitted with a strong " carriage-spring " 
attachment, securing the harmless passage of hard foreign 
substances through the mill. 
The feed is peculiar and effective. It consists of a single 
wooden roller, thickly set with wrought-iron studs, and revolv- 
ing 250 times per minute in close apposition to a horizontal 
metal plate. In addition, there is a wooden plunger which, 
now approaching, and now retreating from the feed roll 
at the rate of 50 reciprocations a minute, first admits, and 
then presses, the entering apples against the roller. This 
was the best feed on the ground, leaving nothing to be desired 
either in its operation or in its adjustment ; but, as before hinted, 
its intermittent action was fatal to the accurate measurement, by 
an indicator, of the power absorbed by the mill, notwithstanding 
which it was clear that, of the two machines, Workman's was 
lighter in draught than Dening's. 
Workman's mill produced an excellent sample of pulp, the 
flesh of the fruit being well separated from the rind, and the pips 
crushed in a very satisfactory manner. 
As in Dening's case, Workman began to chai'ge his press as 
soon as the mill got into operation, but using an essentially dif- 
ferent process. No " cheese," properly so called, was built ; 
but the bed of the press having been first covered by a canvas cloth 
of open mesh, this received a layer of pulp some two or three 
inches thick, which was then completely inclosed by folding the 
cloth. A " former," or wooden frame of suitable size and shape, 
was next dropped over the " cake " thus produced, and a second 
canvas laid therein. A second layer of apple pulp and a second 
inclosing sheet followed, the " former " serving to size each cake, 
and so on, until all the pulp had been disposed in some eight or 
nine " cakes." Actual pressing began at 3.15 P.M. and was 
completed in 39 minutes, while the quantity of juice produced 
from 1,800 lb. of apples was 108 gallons, equal to 6 gallons ex- 
pressed in 2-17 minutes from each 1001b. of fruit. 
Workman's press consists of a strong wooden frame having 
a channelled bed for the reception of pulp, and a platen depressed 
by the action of two screws, operated by means of a winch-handle, 
acting, through a neat system of change-speed gearing, upon 
two worms and worm-wheels, the latter forming nuts for the 
press-screws. This arrangement worked extremely well, and is 
much more convenient to handle than the shifting levers of 
Dening's press. It was competent for either of the men to
