Dairying at Park Royal , 1905. 
Experiment No. 6. 
Losses due to Want of Skill and Care in Churning. 
Two lots of cream were taken, as in the last experiment, 
from the bulk. The first was churned at a low temperature 
and in every respect properly ; the second at a higher 
temperature, the thermometer not being used, and carelessly, 
no notice being taken of it until the butter came in lumps — in 
short, it was overchurned. 
The two lots were then worked and taken out of the churn. 
The first lot being in good grain was passed through the 
Delaiteuse and made up as well as possible. The second lot 
could not be worked in the Delaiteuse, and was only worked 
in the butter- worker, which, to carry out the experiment in its 
entirety, was not too well done. 
The first lot of butter was excellent in every wav. The 
second lot was soft, greasy, and bad in grain and texture. 
The difference in the selling value might vary from 2d. to 3 d. 
per lb. 
Experiment No. 7. 
Losses due to Want of Skill in Working of Butter. 
Four lots of butter, all of which had been well churned in 
one churning and were consequently good in grain, after being 
washed, were worked as follows : — 
No. 1. Dried in the Delaiteuse and then worked and 
made up as well as a skilled dairymaid could do 
the work. 
No. 2. Overworked in the butter- worker only. 
No. 3. Underworked. 
No. 4. Worked in a bowl by hand. 
This experiment, which was followed with great interest by 
the spectators, showed very clearly the difference between the 
four lots of butter. The estimated value between Lot No. 1 and 
Lots Nos. 2 and 3 may be put down at 2d. to 3 d. per lb., 
while the difference between No. 1 and No. 4 was estimated at 
6d. per lb. 
Experiment No. 8. 
Depreciation in Selling Value of Butter carelessly packed. 
Four lots of butter of 3 lb. each (■ i.e ., 12 lb. in all), all equally 
well made, were packed as follows : two lots in baskets for sale 
in a country market ; two lots in boxes for transit by post or 
rail. The samples for the market were packed in the one case as 
neatly and as well as possible ; the other carelessly, with cabbage 
leaves in place of butter muslin, as is still too often seen. The 
difference in the selling value, although the butter was exactly 
the same in quality, may be put down at 2d. per lb.
