Report on the Exhibition of Implements, 
ease with which it can be worked — a child's strength being suf- 
ficient * — and facility with which it is emptied and cleaned. 
Butter Workers are quite recent introductions, for which we are 
undoubtedly indebted to our transatlantic friends, although it 
was a German, Mr. Ahlborn, who first exhibited these valuable 
machines at the Bristol Meeting, when he obtained the prizes 
for two forms suitable for large and small dairies. Previous to 
this, indeed soon after the Philadelphia Exhibition, I was con- 
sulted by Mr. Al lender as to the novelties there, and I strongly 
recommended the Butter Worker invented by P. Embree and Son, 
of West Chester, Philadelphia, of which Ahlborn's machine is a 
close imitation. This was accordingly purchased, and formed 
a part of the exhibit of the Aylesbury Company. It has already 
been so fully described, that I need only state that the butter is 
placed on a revolving table with a convex surface. The butter 
placed on this table as it comes from the churn, is pressed by a 
revolving conical fluted roller ; the axis of this roller has a 
bevel wheel which, working in the gearing placed in the centre 
of the table, causes the butter to revolve. This is very simple 
and efficient ; the edges of the flutings are sharp, and so press 
almost through the butter, more or less cutting it up, and thus 
very thoroughly express the moisture, which collects in a 
channel round the outside of the table, and passes away by 
an opening. Both the Davis's Swing Churn and the Embree 
Butter Worker are now being made for the Aylesbury Dairy 
Company, by Messrs. Bradford, of Manchester, as they have 
recently decided, on account of numerous applications, to supply 
all descriptions of dairy fittings, &c. 
Lawrence's Refrigerator, which, originally invented for brewing 
purposes, is found admirably adapted for rapidly reducing the 
temperature of milk and preparing it for transportation, is so 
well known as to require no explanation ; its efficiency and 
simplicity are undeniable. 
A great novelty as regards this country was the Cooley Creamer, 
manufactured by the Vermont Farm Machinery Company, and 
sold by their English agents, Messrs. Neel, Son, and Anderson, 
of 91, Watling Street, London. It comprises a water-tight box, 
resembling in external form a domestic refrigerator, only that it 
has inlet and outlet pipes, and a thermometer let into the front, 
so that the temperature of the water can be readily seen. The 
cans which are used are 20 inches deep, and 8i in diameter, and 
have covers, which, when fastened down, prevent the access of 
moisture. The milk is thus set under water, the oxidising action 
* Further trials have not confirmed this opinion, for although when empty the 
churn can be worked by a child, yet when duly charged it requires more power 
than might be inferred without a practical test. — Ed.
