e, flesh, and hair, yet if it be moved into portions
of the Eastern counties where the soil is of a totally different
character, it will when matured have lost, to a very considerable
extent, its peculiar characteristics of bone and hair. The changes
wrought may be due in small measure to climate, but the predominant
cause must be due to the variation in the food grown on soils of a
different character.

This question of the original cause or causes of the varying colour of
the pigs in different localities appears to be equally difficult of
solution. As to the continuation in certain districts of pigs of one
colour, custom and even prejudice have a great effect. So strong is this
prejudice that some persons will even declare that the pork of pigs of
the fashionable colour in the neighbourhood is superior to that from
pigs of any other colour. As this weakness is common in districts where
black and where white pigs are kept it must be admitted that prejudice
alone must be the foundation of the belief.

Probably the safest conclusion to arrive at with respect to the
variation in colour of the pigs noticeable in certain districts is that
in the long ago the native pig in the wild state was of the colour of
the soil and the herbage in which it sheltered, and was thus less
conspicuous to its enemies, whether human or animal. A marked instance
of this is to be found in the colour of the common or original pig found
in some parts of the country where the soil is of a decidedly red
colour. In the district referred to one actually hears some farms spoken
of as "red land farms." What more natural than to find in the districts
in which land of this hue predominates that the pigs should be a red
rusty hue such as was the original colour of that breed of pigs now
called the Tamworth breed.

Some persons, who do not agree with this theory of the origin of the
various coloured pigs, cite as a proof of their belief the fact that in
so many districts the pigs are of a mixed colour, and that this peculiar
marking is equally as general in localities as is any particular or
special colour in the pigs. This is perfectly true, and it is probably
due to exactly the same causes, fancy, prejudice, or custom. The
residents in certain districts have grown accustomed to certain things
or certain forms, and are loth to change; the manufacturer of any
article must humour the actual or fancied requirements of his customers
if he is to secure succe
