Nevertheless I cannot doubt that this
process, continued during centuries, would improve and modify any
breed, in the same way as Bakewell, Collins, etc., by this very same
process, only carried on more methodically, did greatly modify, even
during their own lifetimes, the forms and qualities of their cattle.
Slow and insensible changes of this kind could never be recognised
unless actual measurements or careful drawings of the breeds in
question had been made long ago, which might serve for comparison. In
some cases, however, unchanged or but little changed individuals of
the same breed may be found in less civilised districts, where the
breed has been less improved. There is reason to believe that King
Charles's spaniel has been unconsciously modified to a large extent
since the time of that monarch. Some highly competent authorities are
convinced that the setter is directly derived from the spaniel, and
has probably been slowly altered from it. It is known that the English
pointer has been greatly changed within the last century, and in this
case the change has, it is believed, been chiefly effected by crosses
with the fox-hound; but what concerns us is, that the change has been
effected unconsciously and gradually, and yet so effectually, that,
though the old Spanish pointer certainly came from Spain, Mr. Borrow
has not seen, as I am informed by him, any native dog in Spain like
our pointer.
By a similar process of selection, and by careful training, the whole
body of English racehorses have come to surpass in fleetness and size
the parent Arab stock, so that the latter, by the regulations for the
Goodwood Races, are favoured in the weights they carry.
