"The altar theory is exploded now," said Miss Todd. "It is generally recognized that they were burial-places of great chiefs. The body would be placed inside, with stone weapons and drinking-cups, and any other articles the man had loved when he was alive. Then a great heap of stones and earth would be piled over and round it, to keep out the wolves which were the terror of early man. The weather, and perhaps farmers, have taken away the mound, and laid bare the cromlech; but look! here is one that is almost in its natural position."
