600 PROCEEDINGS OF SECTION G. 
In carrying out test 2, all conditions in the manufacture 
of the butter were exactly the same, the only difference 
being in the working as enumerated below .

The above percentages of water go to show that the 
decreased speed of roller favoured a freer escape of moisture. 
Sample 7, with a roller speed of 45 revolutions per 
minute, and two workings, of two and a half and one and a 
half minutes respectively, gives 12 per cent. water; and 
sample 9, with one working of the same time (four minutes), 
and of the same speed, leaves-13°5 per cent. of water in 
the butter; while the slow working of boxes 8 and 10 for 
an equal number of minutes to 7 and 9 produce a much 
drier article. All along I have been opposed to fast work- 
img, and I would suggest to factory managers and their 
assistants the necessity for closer attention to this important 
factor in. butter-making. No. 9 illustrates in a striking 
manner that water becomes locked up in the body of butter 
when it is exposed too long to the influence of a quick 
moving roller. 
Test 3.—Butter Grains and Draimage in Churn. 
Test 3 was undertaken to asce:cain what effect the sizes 
of butter grains in the churn would have on the dryness of 
the butter, and the influence of draining in the churn, and 
also salting. 
Altogether, eight lots of butter were made. The first four 
~ were treated as follows :— : ;
