"No; they quarrelled as to which was which, and they are not now on speaking terms. I have two great-uncles. Theirs is a sad tale. Their souls were out wandering one day, and inadvertently they crossed and recrossed each other's tracks so that their spiritual threads of attachment got twisted. They found this out, and that they were getting tangled up. What one of them should have done would have been to have stood still and let the other jump over and dive under his brother's thread till he had cleared himself. But my maternal great-uncles--I think I forgot to say they were related to me through my mother--they were men of peppery tempers and they could not understand this. They had no education. So they jumped one this way and one another, each abusing the other, and made the tangle more complete. That was about six thousand years ago, and they are now so knotted up that I do not suppose they will be clear of one another till time is no more." He paused and laughed. Then I said: "It must have been very hard for you to be without pottery of any sort." "It was," replied H. P. (this stands for Homo Præhistoricus, not for House-Parlourmaid or Hardy Perennial), "very hard. We had skins for water and milk----" "Oh! you had milk. I supposed you had no cows." "Nor had we, but the reindeer were beginning to get docile and be tamed. If we caught young deer we brought them up to be pets for our children. And so it came about that as they grew up we found out that we could milk them into skins. But that gave it a smack, and whenever we desired a fresh draught there was nothing for it but to lie flat on the ground under a doe reindeer and suck for all we were worth. It was hard. Horses were hunted. It did not occur to us that they could be tamed and saddled and mounted. Oh! it was not right. It was not fair that you should have everything and we nothing--nothing--nothing! Why should you have all and we have had naught?" "Because I belong to the twentieth century. Thirty-three generations go to a thousand years. There are some two hundred and sixty-four or two hundred and seventy generations intervening between you and me. Each generation makes some discovery that advances civilisation a stage, the next enters on the discoveries of the preceding generations, and so culture advances stage by stage. Man is infinitely progressive, the brute beast is not." "That is true," he replied. "I invented butter, which was unknown to my ancestors, the unbuttered man." "Indeed!"
