india-rubber, but it is liable to get jammed too tightly, and is 
then difficult to open. This churn is strengthened by two 
metal bottoms, with one of wood between them. The lower 
bottom is of course the one most liable to be damaged, but 
should any small leak occur in the upper one, it might escape 
observation till the milk was injured by the stale leakings. In 
addition to their usual comprehensive collection of appliances 
for dairy use, this Company exhibited a Model Ensilage Stack- 
Press that will be described later on. 
Messrs. Manley and Hartley showed two IVIilk Pony Car- 
riages, with driver's seat, for conveying milk for retail purposes. 
One (No. 134) with wrought-iron wheels, to take a single 
20-gallon can ; the other (iVo. 133), with wooden wheels, to take 
two 18-gallon cans. By raising the shafts, the can in j\o. 134, 
and the hind can in Xo. 133, can be taken into the cart with 
a very short lift : but the front can in Xo. 133 must either be 
raised with a high lift into its place, or be filled in the carriage. 
The Dairy Supply Co. showed some convenient little Metal 
Stands for holding Eggs, and a cheap Milkman's Lock to 
prevent the theft of milk-cans in towns. The can is hung by 
the milk-carrier upon a bracket padlock, and can only be re- 
moved by the householder's key. 
Dairies that set milk for cream in the neighbourhood of 
London have vainly endeavoured to find a market for skim- 
milk, sold as such, among the London poor. It is said that it 
can be purchased largely at Id. per gallon, and that much of it 
has been thrown away as valueless. Laicrence's Lactoleofract 
(y>o. 4038) is an apparatus by which fats and oils can be 
thoroughly emulsified with skim-milk to replace the butter 
that has been extracted from it as cream. In order to enrich 
5 gallons of milk, 1 quart of oil is thoroughly mixed by a steam 
jet with 2 quarts of the milk, and this strong emulsion is then 
stirred into the rest of the milk. The milk and the oil are 
placed in two vessels ; a small pipe and tap regulate the flow 
of each into a larger pipe, where the liquids are together con- 
verted into spray by a jet of steam, which drives them into the 
collecting chamber in a state of thorough combination. It is 
claimed for this invention that skim-milk thus enriched can 
be profitably used for cheese-making, for -confectionery pur- 
poses, and for the feeding of young stock. Mr. Lawrence 
states that he is now fattening calves at much less than the 
usual cost by giving them Id. worth of oil added in this way 
to a gallon of skim-milk, which he purchases for Id. 
No. 5062 is a Calf and Lamb Feeder, made by Fawcett and 
Co., on the feeding-bottle principle, under Hudson's patent.
