dairy appliances, the improvement of which is annually becom- 
ing of more importance to the English dairy-farmer, both on 
account of the great scarcity and increasing cost of skilled 
labour, and in consequence of the improved quality of foreign 
dairy products." 
This exhibition at Bristol, and the interest aroused therein, 
no doubt paved the way for the organisation of the " Inter- 
national Working Dairy " at the Kilburn Show, which was the 
first example of an undertaking which has now become familiar, 
on a more or less complete plan, in show-yards all over the 
country. The dairy at Kilburn was divided into two sec- 
tions — English and foreign. The English section, with some 
American appliances, was worked by the Aylesbury Dairy 
Company, the foreign section being in the hands of M. Ahlborn, 
of Hildesheim. The great novelty of the Kilburn Dairy was 
the Laval Cream Separator, which was awarded a silver medal. 
This was the first appearance of a separator in England, and 
the curiosity and controversy which it aroused were extraordinary. 
Even the Butter Extractor, which distinguished the Windsor 
Dairy, was a less startling innovation, inasmuch as the utilisa- 
tion of centrifugal force is now familiar, whereas at that time 
no method of separating cream, other than by gravitation, had 
been dreamt of in the philosophy of the British dairy-farmer. 
Other prominent novelties in the Kilburn Dairy were the 
'• Cooley Creamer" and the American " cot-swing " churn, both 
of which have since come into use to some extent. 
At the following Show — Carlisle — the Council, " in conse- 
quence," to quote from their report of May 22, 1880, " of the 
great interest manifested in the exhibition of dairy machinery 
at work in the Kilburn Showyard," arranged for an exhibition 
of the chief kinds of butter-making utensils, and of butter- 
making on the several systems prevailing " in different districts 
of England, on the Continent of Europe, and in America." 
The attempt to show rival methods was soon abandoned in 
favour of the exhibition of the method which most closely follows 
scientific principles and improved practice. 
At Derby, in 1882, the Working Dairy was recognised as 
one of the prominent permanent departments of the Show. 
Lectures were delivered during the Show by Dr. Voelcker, and 
there was a trial of cream separators in which three machines 
— the Laval, the Lefeldt, and the Danish — took part. 
A more elaborate trial of separators was arranged for the 
following year at Heading, but it was marred by an application 
for an injunction in Chancery against the Society, as well as 
against exhibitors of some of the machines entered. The ap-
