THE hollow in which the castle of Watho lay was a cleft in a plain rather than a valley among hills, for at the top of its steep sides, both north and south, was a tableland, large and wide. It was covered with rich grass and flowers, with here and there a wood, the outlying colony of a great forest. These grassy plains were the finest hunting grounds in the world. Great herds of small but fierce cattle, with humps and shaggy manes, roved about them, also antelopes and gnus, and the tiny roedeer, while the woods were swarming with wild creatures. The tables of the castle were mainly supplied from them. The chief of Watho's huntsmen was a fine fellow, and when Photogen began to outgrow the training she could give him, she handed him over to Fargu. He with a will set about teaching him all he knew. He got him pony after pony, larger and larger as he grew, every one less manageable than that which had preceded it, and advanced him from pony to horse, and from horse to horse, until he was equal to anything in that kind which the country produced. In similar fashion he trained him to the use of bow and arrow, substituting every three months a stronger bow and longer arrows; and soon he became, even on horseback, a wonderful archer. He was but fourteen when he killed his first bull, causing jubilation among the huntsmen, and indeed, through all the castle, for there too he was the favorite. Every day, almost as soon as the sun was up, he went out hunting, and would in general be out nearly the whole of the day. But Watho had laid upon Fargu just one commandment, namely, that Photogen should on no account, whatever the plea, be out until sundown, or so near it as to wake in him the desire of seeing what was going to happen; and this commandment Fargu was anxiously careful not to break; for although he would not have trembled had a whole herd of bulls come down upon him, charging at full speed across the level, and not an arrow left in his quiver, he was more than afraid of his mistress. When she looked at him in a certain way, he felt, he said, as if his heart turned to ashes in his breast, and what ran in his veins was no longer blood, but milk and water. So that, ere long, as Photogen grew older, Fargu began to tremble, for he found it steadily growing harder to restrain him. So full of life was he, as Fargu said to his mistress, much to her content, that he was more like a live thunderbolt than a human being. He did not know what fear was, and that not because he did not know danger; for he had had a severe laceration from the razor-like tusk of a boar -- whose spine, however, he had severed with one blow of his hunting knife, before Fargu could reach him with defense. When he would spur his horse into the midst of a herd of bulls, carrying only his bow and his short sword, or shoot an arrow into a herd, and go after it as if to reclaim it for a runaway shaft, arriving in time to follow it with a spear thrust before the wounded animal knew which way to charge, Fargu thought with terror how it would be when he came to know the temptation of the huddle-spot leopards, and the knife-clawed lynxes, with which the forest was haunted. For the boy had been so steeped in the sun, from childhood so saturated with his influence, that he looked upon every danger from a sovereign height of courage. When, therefore, he was approaching his sixteenth year, Fargu ventured to beg Watho that she would lay her commands upon the youth himself, and release him from responsibility for him. One might as soon hold a tawny-maned lion as Photogen, he said. Watho called the youth, and in the presence of Fargu laid her command upon him never to be out when the rim of the sun should touch the horizon, accompanying the prohibition with hints of consequences, none the less awful than they were obscure. Photogen listened respectfully, but, knowing neither the taste of fear nor the temptation of the night, her words were but sounds to him.
