large. Dismantling and cleaning (which by the way was very 
thoroughly done) took twenty-six minutes, and two-and-a-quarter 
minutes to set up again. This is a similar machine to that 
described in the Report on the Implements at Windsor (vol. xxv. 
Second Series, p. 530), but with some improvements in minor 
details. It did its work well, is simple in construction, easy to 
clean, and has one most noticeable feature which no other 
separator had, in that it has not to be bolted down or fixed in 
any way. Consequently, even when running at full speed, if 
the belt (a thin cotton one) wants tightening, it is only neces- 
sary to pull the machine and the belt is at once put to the right 
tension. When finished w"ith, it can be rolled away like a milk 
chum, and no special foundations are wanted. These are matters 
of importance in many situations, and show also how perfectly 
■well balanced the parts must be, a most essential point in high- 
speed machinery. A separate contrivance, in the form of a 
very simple centrifugal pump attached to the machine, enables 
the skim-milk to be elevated after separation. Further reference 
is made to this machine in the report upon Miscellaneous Imple- 
ments (see p. 537). 
To this separator the First Prize in this class was awarded. 
No. 1234, The Reading Royal," price 45L — This machine 
separated 117 gallons of milk per hour, the stated capability being 
150 gallons. The power requu-ed was 2-574 h.p., which gave 
the worst result in this respect, and also only showed a higher 
efficiency than the Victoria." The number of revolutions was 
7,700 per minute, and temperature of separation 88° to 93° Fahr. 
Separation was veiy efficiently performed, the best result being 
obtained — viz. 97'4 per cent, of the butter-fat in the whole-milk 
removed, and only 0'129 per cent, of fat left in the skim-milk. 
The loss was large, but was due partly to a leak in the machine 
during its first trial run. It took fourteen minutes to dismantle 
and clean, and one-and-a-half minute to put together, this 
being a good result, though the cleaning, &c., were not so 
thoroughly nor so easily done as with the " Alexandra." 
To this machine the Second Prize was awarded in this 
class. 
No. 1235, The " Leviathan;' price 62L— This is the " Laval " 
power machine fitted with the steel discs referred to on p. 504. 
It separated the enormous quantity of 351 gallons in the hour, 
this result being close upon the 360 gallons it was stated to deal 
with. In consequence of this, it necessarily requires constant 
feeding and attention. The power used was 1'29G h.p., a result 
next best to the " Alexandra," and the efficiency of this machine 
was the highest of any. The revolutions wei'e 6,000 per
