Experiments in the Dairy .

secondly, with the practical work of the dairy ; but before 
doing this the description of a few details is necessary. 
The milk from every cow in the Showyard was brought by 
the herdsman to the dairy, where it was weighed and paid for, 
the name of the owner. and the number of the cow being taken. 
It was thus possible to keep every single lot of milk separate ; 
and this was done, churns and buckets being carefully labelled 
with the names of the various breeds of cattle ; as each lot of 
milk came in it was poured into its proper receptacle. 
On Tuesday afternoon, the cows were milked out clean at 
5 and 5.30 p.m. for the milking trials, the whole of Wednesday’s 
milk being kept for that purpose ; on the other days the cows 
were milked by the herdsmen at times varying from 7 to 8 
a.m., and from 5 to 6 p.m. ; so that the morning milk may be 
said to have been the secretion of fourteen hours and the 
evening milk of ten hours or thereabouts. 
The milk of Tuesday afternoon would naturally show a 
high percentage of fat in all cases, except where the cows were 
entered only in the butter-test classes, as the animals having 
been judged in the inspection classes were not milked out 
until late on the Tuesday morning ; the milk of Tuesday 
evening was therefore the secretion of only a few hours. 
These remarks are necessary to explain the following 
experiment. 
Experiment No. 1. 
Butter made f rom Milks of different periods of Secretion. 
Three gallons of the milk of each of the ten different herds 
of cattle entered in the milk-yield classes were set aside on 
Tuesday evening ; they were separated the following morning

as nearly as possible to the money value, avoiding fractions less than \d.
