Though we could not see him, guided by his voice we made our way to the hut. Antonio had already got in and thrown himself on the ground, but Uncle Richard roused him up, and compelled him to assist in lighting the fire. We soon had a genial blaze, at which we warmed our chilled limbs. I saw Lion looking up in my face, as much as to say, "Master, that was a foolish thing you did just now; in another minute you would have been dead, had I not kept some warmth in you with my body." I patted his head, and he wagged his tail, and smiled as dogs can smile when pleased. In spite of the blazing fire we kept up all night, we felt the cold greatly. Indeed, I had never felt so chilled in all my life; it seemed to pierce to the very marrow. Lion lay down close to the fire, and almost singed his hair, showing that he too was suffering from the cold. Fearing that the fire might go out, Uncle Richard insisted that one of us should remain awake; and he himself undertook to keep the first watch. We first took our supper, but I fell asleep with a piece of food in my mouth. The training Uncle Richard had had at sea enabled him to keep awake, although I dare say he was as sleepy as any of us. He at last aroused me, and charged me not to let the fire get low. "I can trust you better than I can Antonio or the guide," he observed. "However strong may be your impulse to sleep, do not yield to it, as our lives may depend on the fire being kept up." I promised to keep a faithful watch, and, rising to my feet, began to walk about. In a moment more Uncle Richard was fast asleep. So strong was the desire I felt to lie down and close my eyes, that I was afraid of stopping, and kept pacing up and down the hut, rubbing my hands together, and every now and then putting on an additional stick, or scraping up the ashes. The time passed slowly by; the wind moaned amid the bleak crags which overtopped the hut, and I fancied I heard the cries of wild beasts. The sleepers, overcome with fatigue, did not even move, and as I gazed at them they looked as if stretched out in death. Every now and then, however, Lion lifted up his head, as if to see that all was right; and just as my watch was over, and I was about to call Antonio, he got up and stretched himself. "Now, Lion, if Antonio drops asleep, remember to call me or Uncle Richard. I will trust you, good dog. You understand?" Lion wagged his tail, and gave a low bark; and I felt confident that he would do as I had ordered him. I then called Antonio, and gave him the same instructions and warning which Uncle Richard had given me. "Do not fear, senor," he answered--giving, however, an ominous yawn; "I'll keep my eyes open."
