The most practicable and easily handled size is that in general 
use in the London trade. These are all of uniform capacity, and 
hold 8 barn or 17 imperial gallons, and weigh, when full, 
If cwt. That shown by Mr. Campion was mounted on wheels, 
and therefore unsuited to railway transit. Mr. Cluett's was made 
of a uniform width throughout ; the lid fitting inside and float- 
ing on the surface of the milk — beautiful in theory, but unsound 
in practice — a little rough usage would prevent the lid from 
working. Vipan and Headly showed several substantial cans. 
They were constructed of strong tinned charcoal-iron ; the largest 
was divided into two compartments, mounted on wheels, and 
fitted with locking cover and ventilating pipe, and taps for 
drawing off the milk. A smaller can by the same makers was 
also mounted on low wheels, with the object of facilitating its 
movement when full. No. 1918, exhibited by Messrs. Alway 
and Sons, was considered the best adapted for railway transit ; 
it is tapering from the bottom upwards. The material of which 
it is constructed is of itself sufficiently strong to enable the 
use of hoops or outside casing to be dispensed with ; and the 
can is free from inside angles and projections, is fitted up with 
malleable cast-iron top, and also with an inner and outer lid. 
A practical fault would be met by constructing both in one, in 
the form of an ordinary bottle-stopper : when separate, the inner 
lid is liable to get lost. 
The cans were all subjected to a severe practical test ; they 
were filled with milk and placed side by side on a truck, and 
drawn by a traction engine at a high speed over very rough 
ground for a considerable distance round the Showyard, the 
Judges and others riding on the truck. AD the lids of the cans 
were removed in order to observe the action of the milk 
inside the cans of different constructions. Having tested and 
thoroughly examined them in every possible way, we unani- 
mously agreed to award the prize of lOZ. to No. 1918, Alway 
and Sons, as most nearly fulfilling all the practical requirements 
of the Society, highly commending Vipan and Headly for No.

Class II. — Churns capable of dealing with a Quantity 
OF Milk sufficient to pkoduce not more than 20 lbs. 
OF BUTTEE. 
There were 19 entries in this Class, contributed by 14 differ- 
ent exhibitors. The estimated capacity of the different churns 
varied from 7 to 70 gallons ; the Society's instructions were 
explicit, so that the latter were equally as eligible as the former. 
Of these 11 came up for trial. A line of shafting, driven by
