When further improved by the same slow & gradual process they will spread more widely, & will get recognised as something distinct & valuable, & will then probably first receive a name. In semi-civilised countries, with little freer communication, the spreading & knowledge of any new sub-breed would be very slow. As soon as the point of value of the new sub-breed was once recog acknowledged, there would always be a tendency slowly to augment the modification slowly whatever their nature to augment, by owing to what I have called unconscious selection
