"Well, now I know how you feel about this thing," said White Otter. "You must do as you find it in your heart. But, my brother, I must tell you that I am going back there. Yes, it is in my heart to do this thing. Perhaps if I hear something I will run out. But I am going to start in there. Perhaps I will meet those Evil People. I believe that this is a very mysterious place, but I am going to find out something. Now I am going ahead. My brother, Little Raven, how do you feel about this thing?"

"I believe that you are very brave, but it is a foolish thing to do," replied Little Raven. "You do not know about this place. I have heard some very brave warriors tell about it. If you go in there, I believe that you will surely come to harm. No, I will not go any farther."

"Well, my brothers, I must do what it is in my heart to do," declared White Otter, as he prepared to advance into the black depths of the cave.

Aware that it would be useless to attempt to dissuade him, Sun Bird and Little Raven remained silent. Their hearts filled with gloomy misgivings, however, as White Otter drew several arrows from his quiver, and crawled slowly forward into the dark, forbidding interior of the cavern. When he had disappeared from their sight they sat in glum silence, listening fearfully for some sound which might warn them of the fate of their comrade. When they heard nothing their fears increased, and Sun Bird called softly into the darkness. Then they waited in nervous suspense as the moments passed and their eager inquiry went unanswered. Tortured by a multitude of alarming possibilities, Sun Bird again sent an anxious inquiry into the black depths of the cavern. This time they received a short, indistinct reply. It assured them that for the moment their comrade was safe, and their hearts bounded with joy.

"White Otter is very brave to do this thing," declared Little Raven.

"Yes, he is very fearless, but it is a bad thing to do," replied Sun Bird. "Perhaps he will make the Evil People mad. Then they may bring trouble to our people."

In the meantime the young Ogalala was advancing cautiously into the unexplored depths of the cavern. As he continued he found that the cave shrunk greatly in height, while it lost little in width. Therefore, although he was compelled to crawl painfully along on his hands and knees, he still had plenty of room if he cared to turn around. White Otter found himself in a smother of darkness, which made it impossible to see a bow-length before him. As his eyes were of little avail, he depended upon his ears to warn him of peril. Keeping in mind the tales which he had heard from Sun Bird and Little Raven, he moved forward very slowly, stopping after every short advance to listen for the strange noises which he expected to hear at any moment.

Then from somewhere in the impenetrable blackness came a peculiar whimpering cry that sent a thrill through him, and made his heart beat wildly. After waiting some moments in trying suspense he again heard the uncanny sound, and located it some distance ahead of him. For some time White Otter was undecided just what to do. His first impulse was to turn about, and retreat from the weird place into which he had so rashly ventured. Then curiosity overcame fear, and he determined to at least have a look at these unknown demons that created such fear among the superstitious Minneconjoux. He recalled that whoever claimed to have ventured into the depths of the cave had escaped unhurt, and old Spotted Face even declared that he had actually seen the eyes of these mysterious creatures before he was warned to retreat from their stronghold. Therefore, White Otter believed that he, too, would be equally fortunate, and he decided to hold his ground and await further developments.

Convinced that whatever threatened him was still in front, White Otter peered anxiously forward into the darkness. The sounds had ceased, however, and he wondered whether he had been discovered. Fitting an arrow to his bow, he waited to be attacked. Then, as nothing came to disturb him, he became bolder. Determined to learn what had made the strange noise, he again crawled forward to investigate.

White Otter had not gone a bow-length when the same strange whimpering cry brought him to a stop. Then, as he listened to hear it repeated, another sound reached his ears. It was a low rumbling growl, and the young Ogalala immediately read defiance in the tone. At first he failed to recognize it, and all sorts of superstitious fears crowded into his mind. He wondered if he had actually invaded the home of some great Thunder Being. His confidence weakened at the thought, for he knew that the bravest warrior could not survive an encounter with one of those terrific monsters. Then he again heard the angry challenge, and at once it became familiar. A few moments later he saw two spots of greenish light shining in the darkness, and he realized that he was confronted by one of the great mountain cats. Once before he had fought a fierce encounter with one of these savage creatures, and he knew what to expect. However, he was greatly relieved to know that he was threatened by an adversary that was without magic power to turn aside his arrows, as the mysterious Thunder Beings were said to do.
