rge extent, to a distinguished Belgian agriculturist, Baron Peers of
Oostcamp, Bruges; but at the present day a general committee composed of
representatives of nearly every civilised nation has been formed, and
delegates from such countries attend the Congresses, which are held
every two years. The literature which has arisen out of these
International Congresses has been disseminated in different countries,
and has been instrumental in placing the dairy industry on a thoroughly
scientific basis.

_Milk Supply of the United Kingdom._--The milk supply of the United
Kingdom has steadily grown from year to year, and in relation to the
population works out at fifteen gallons per head. The manner in which
these figures are arrived at is shown in the following estimate:

The population of the United Kingdom is now about
45,500,000. The number of cows or heifers in calf or in
milk in June, 1909, was 3,360,600; the number in 1910 was
probably about 4,400,000.

Of these about 300,000 were heifers that had not yet
produced any milk. The actual milking class, therefore,
comprised about 4,100,000 cows and heifers; of these,
about 600,000 were heifers that calved in the winter and
spring of 1909-10, and 300,000 were heifers that calved in
the summer and autumn of 1910. The number of cows that
produced two or more calves may be taken to be about
3,200,000; of these about 600,000 should have produced
their second calf in the winter and spring 1909-10, and
would be milked as heifers in the summer and autumn of
1910; the number of mature cows from which a full season's
supply of milk was obtained during the twelve months from
June 5, 1909, to June 4, 1910, was apparently about
2,600,000. A large quantity of milk is yielded during the
year by cows sold or lost during the twelve months before
the census. Possibly ten per cent. of the milk produced in
the twelve months from June, 1909, to June, 1910, was
yielded by cows that were sold or lost before the census
of June, 1910.

It is estimated that the 3,200,000 cows (including the
600,000 that up to the winter of 1909-10 were heifers)
produced, on the average, 44 cwts. (480 gallons) of milk
per head in the twelve months from June 5, 1909, to June
4, 1910; the 300,000 heifers that calved in the summer and
autumn, 30 cwts. (330 gallons) per head; the 600,000
heifers that calved in the winter and spring of 1909-10,
15 cwts
