536 The Trials of M Hieing Machines , 1913. 
3. A group of four cows will be allotted to each machine, the lots being, 
drawn by the Society. 
4. The groups of cows will be chosen to give as nearly as possible the 
same weight of milk. The group letter will be attached to each animal. 
5. The owner of the cows will see that they are thoroughly clean before 
the trials commence and during the trials. Damp cloths may be used before 
each milking to clean the teats and udders. 
6. Both in the preliminary and official trials, the milk will be weighed by 
the Stewards after the milking machine has completed its task and before the 
cows are stripped. The cows in all cases will be stripped by the cowman 
employed on the farm, and not by the competitors, and the weight of the 
strippings will also be taken by the Stewards. 
7. The Bacteriologists will take samples at each milking. 
8. Only the owner of the machine or his agent and the operator will be 
allowed to be present during the trial of any machine, and no person other 
than the Judges, Stewards, and other representatives of the Society will be 
allowed in the sheds during the trial. Competitors will not be allowed to be 
present during the trial of machines other than their own. 
9. The Stewards have the power to disqualify any machine which does not 
comply with the conditions governing the trials, and to order the removal of 
any person who does not conform to the regulations of the Society or to the 
directions of the Stewards. 
10. In cleaning the machines, cold water, hot water, and steam will only 
be allowed. The use of antiseptics is prohibited. The cleaning of each 
machine must be done in the presence of the Stewards or Judges. After 
cleaning, the machines will be stored in a locked up room. 
11. Any machine using a teat syphon or any fitting necessitating the 
insertion of a tube or any other contrivance into the teats of the cows will not 
be allowed to be tried, and will be disqualified from the competition. 
12. Bepairs and renewals to machines after the commencement of the 
trials on Friday, April 18, must be carried out in the presence of the Judges 
or Stewards, who will take note of any such repairs or renewals. 
13. The Judges have full power to try the machines on various groups of 
cows, and generally to do anything necessary to ensure the thorough testing of 
any particular machine. 
In accordance with Regulations 3 and 4, the cows were 
most judiciously and fairly divided into groups by Mr. Burkitt, 
the manager of Messrs. Bolckow, Vaughan & Company’s farms. 
In one or two cases only had cows to be changed owing to their 
being nervous and irritable, caused no doubt by the presence 
of strangers in the byres. 
The cattle were excellent specimens of dairy Shorthorns, 
with good udders, and were considered both by the Judges, 
officials and competitors as eminently suitable for the trials — 
indeed the opinion was generally expressed that it would be 
hard to find a lot of animals better qualified for the purpose. 
> The preliminary trials commenced on Friday, April 18, at 
5.30 a.m., and were continued daily until Monday evening, the 
21st instant, when, thanks to the hearty co-operation of the 
exhibitors and their attendants, everything was going as 
smoothly as possible.
