The Trials of Churns at Cambridge. 
the two classes assigned to these competitions, and of the prizes 
offered by the Society : — 
Class YI. Churns capable of dealing with 10 quarts and 
upwards of cream (not to exceed one man power). First 
Prize 10?. Second Prize 61. Third Prize 4 1. 
Class YII. Churns capable of dealing with from 5 to 10 
quarts of cream (not to exceed one man power). First Prize 
hi. Second Prize 3 1. Third Prize 21. 
The attention of the Judges was directed by the Society to 
the following points : — 
] . Simplicity of construction and durability, combined with facility of 
cleaning and of inspection. 
2. Efficiency. 
3. Cost. 
4. 1’ower required. 
The churns which competed are indicated in the tables on 
the opposite page ; and it should be noted that some of the com- 
petitors made a more modest estimate of the capabilities of their 
churns in entering for these competitions than they had done in 
previous catalogue descriptions. 
The trials were conducted at the Dairy in the Cambridge 
Showyard on Wednesday, June 20, and the three following days. 
They were chiefly of inteiest because they gave an opportunity 
of comparing the new quick-churning machines with those of 
older make. The “ Disc ” Churn, it may be remembered, was 
awarded the Society’s Silver Medal last year at Chester as the 
pioneer of a new movement in the direction of quick churning. 
In addition to the “ Disc ” Churns two other quick-working 
machines competed, viz., Bradford’s “ Fishback,” and Vincent’s 
Churn. These have without doubt come forward as a result 
of the interest aroused by the “ Disc ” Churn. 
The ordinary 8-quart “ Disc ” Churn was fully described in 
the Journal last year. 1 This machine was entered, and competed 
in Class VII. The two “ Disc ” Churns which competed in 
Class YI. are constructed on similar principles, but with twin 
discs revolving on the same spindle, the discs in one case being 
concave at the periphery, and in the other divided into points — 
hence the name “ star” discs. 
Vincent’s Churn was identical in construction in both 
classes. This is a box churn in which a dasher is placed on an 
oblique spindle. The dasher is made to revolve quickly by cog- 
wheel gearing placed at the upper end of the spindle.
