James Wilson, The evolution of British cattle and the fashioning of breeds…
“ To show that the British variety of Bos longifrons was black, we must anticipate some part of what is to follow, on the understanding that what is now taken on credit will be made good hereafter. It is a well-known fact in human history that, as one race retires before another, the retiring and the invading races are usually accompanied by some part of their live stock, and above all by their cattle which, in earlier times, not only afforded food and clothing but took a chief share in tilling the earth, and thus were an outstanding necessity in man's existence. ”
