The Trials of Cream Separators at Doncaster.

though inferior to them in respect of power required and efficiency, 
effected much better separation, and, besides separating a quantity- 
sufficient for all but exceptional circumstances, was easier of 
dismantling and cleaning than the "Leviathan." The latter 
was essentially a machine for a lai-ge factory, but otherwise it 
was felt by the Judges that its extra cost, and the need of extra 
attention, care and time in cleaning, &c., would not be wan-anted. 
The Danish machine was an excellent one in construction, and 
separated a large quantity of milk, but the separation was 
inefficient, though the regulation of thickness of cream was best 
done by this separator. The "Victoria" gave separation of 
high quality, but dealt with the smallest amount of milk, and 
was the only one to produce excessive frothiness of cream. 
Accordingly the Judges' award was : — 
FiEST Prize of 30/. to R. A. Listee & Co., Dursley, for No. 1032, The 
" Alexandra " No. 2 ; price 49/. 
Seco-d Pbize of 20/. to the D.iiEY SurrLT Co. for No. 1234, The " Reading 
Royal," price 45/. 
Class III. Hand Machines. 
These were tried very exhaustively, measured runs of from 
twenty minutes to half-an-hour being given to the machines on 
each of the three days, June 17, 19, 20. The amount of milk 
separated was the average of three runs, and at one of them 
samples of the skim-milk were taken for analysis. The quantities 
of milk dealt with being smaller than with the power-machines, 
one and the same lot of milk could be used for all, and was, 
after thorough mixing in a tank, given out to each machine 
alike. The results are stated in the same terms as in the case 
of the power machines — viz. the separated products in pounds 
per hour and in percentages, the temperatures in degrees 
Fahrenheit. The loss includes what was left in the drum or 
bowl, and appears more when multiplied for the hour's run 
than would be the case in reality, as there would be only the 
same amount at the end of the hour as after a much shorter 
time. 
No. 958, The " FidonVt," price 13L 10s.— 18^ gallons of milk 
were separated in the hour, with a horse-power of "15, which 
was very fair, though, as with the power machine, when the 
efficiency was considered, the result came out badly, and 
inferior to all except the " Baby," Two-and-a-half minutes 
were taken in getting up speed, the skim-milk came three- 
quarters of a minute later, and the cream in one-and-a-half 
minutes. The number of revolutions of the handle was 48,
