precautions as may be necessary to prevent the occurrence of 
accidents likely to arise from the high speed at which the ma- 
chines are driven. 
4. The duration of each trial is to be an hour. 
5. All the Separators are to be supplied from a vat common 
to all. This vat will be raised to a sufficient height to command 
the Separators, and a pipe furnished with a stop-cock will be 
led from the mixinsr-trough connected with the vat to each 
machine. 
6. The Separators in each class will be tested simultaneously. 
7. The Separators will all be worked by the same shaft, the 
speed of which will be kept as nearly as possible at 1.50 revolutions 
per minute, the exact speed being indicated by a speed indicator, 
and duly noted at regular intervals during the trial. The shaft 
will be 2 inches in diameter. 
8. The milk will not necessarily be of one day's milking, but 
it must be sweet and good. The vat will have a double bottom 
supplied with steam, and the milk will be heated to such a 
point that it will reach the separators at 95° Fahr. as nearly 
as may be. 
9. The skim-milk and the cream delivered by the machines 
will be weighed separately. 
10. The Chemist to the Royal Agricultural Society will 
analyse the skim-milk from each machine, and for this purpose 
he will take such samples as he may deem necessary. 
11. The Separators in each class will all start at the same 
time. The Judges will note the time that elapses in each 
machine between the time of starting and the time when com- 
plete separation commences to take place. The imperfectly 
separated milk will be put back into the supply vat of each 
machine. The rate of working at intervals, during the run, will 
be ascertained by noting the time in which a given measure is 
filled. All the machines will cease working on fresh milk at 
the same time, and the time required to finish their charges 
will be noted. 
12. The rate of separation will be calculated from the quan- 
tity of milk treated (ascertained by the quantity of cream and 
skim-milk delivered) from the time when complete separation 
takes place to the time of simultaneous stopping of the milk 
supply. 
13. The cylinders of the machines are to be examined at the 
conclusion of the trials to ascertain how much milk remains 
in them. 
14. If any machine leaves more than '4 per cent, of butter- 
fat in the skim-milk, it will be considered out of the com- 
petition.
