Further back than this we have no one to question except those shadowy men of the Stone Age who have left us heaps of their implements, but none of their bones. They were not so careful of the bones of horses, which lie in thousands about the precincts of their untidy villages, but not a scrawl on a bit of a mammoth tusk has been found to indicate whether these were ridden and driven, or only hunted and eaten. Why should it be recorded that Cadmus invented letters? Why should we inquire who first made gunpowder and glass? Why should every schoolboy be taught that Watt was the inventor of the steam engine? Can any of these be put in the scale, as benefactors of our race, with the man who first trained a horse to carry him on its back, or drew milk with his hands from the udders of a cow? The familiarity of the thing has made us callous to the wonder of it. Let us put it before us, like a painting or a statue, and have a good look at it. There is a farmhouse, any common farmhouse, just one of the molecules that constitute the mass of our wholesome country life. A horse is being harnessed for the plough: its ancestors sniffed the wind on the steppes of Tartary. Meek cows are standing to be milked: when primitive man first knew them in their native forests he used to give them a wide berth, for his flint arrows fell harmless off their tough hides, and they were fierce exceedingly. A cock is crowing on the fence as if the whole farm belonged to himself: he ought to be skulking in an Indian jungle. The sheep have no business here; their place is on the rocky mountains of Asia. As for the dog, it is difficult to assign it a country, for it owns no wild kindred in any part of the world, but it ought at least to be worrying the sheep. If there is an ass, it is a native of Abyssinia, and the Turkeys are Americans. The cat derives its descent from an Egyptian. But all these are of one country now and of one religion. They know no home nor desire any, except the farmhouse, in which they were born and bred, and the lord of it is their lord, to whom they look for food and protection. And what would he do without them? What should we do without them? It is impossible to conceive that life could be carried on if we were deprived of these obedient and uncomplaining servants. High civilisation has been attained without steam engines; education, as we use the term now, is superfluous--Runjeet Singh, the Lion of the Punjab, could neither read nor write; the human race has prospered and multiplied without the knowledge of iron; but we know of no time when man did without domestic animals.
