Why there should be anything more alarming in twelve o'clock than in any other hour I can't pretend to say, but the fact none will question. Mr. Peabody felt a nervous thrill when his eyes rested on the dial. He looked about him, and the darkness seemed blacker and more awe-inspiring than ever, now that he knew it to be midnight.

"Will it ever be morning?" he groaned. "Four long hours at least before there will be light. I don't know how I am going to stand it."

Now, there was attached to the wagon-train one of those universally despised but useful animals, a donkey, the private property of a man from Iowa, who expected to make it of service in California. The animal was tethered near the camp, and was generally quiet. But to-night he was wakeful, and managed about midnight to slip his tether, and wandered off. Peabody did not observe his escape. His vigilance was somewhat relaxed, and with his head down he gave way to mournful reflection. Suddenly the donkey, who was now but a few rods distant, uplifted his voice in a roar which the night stillness made louder than usual. It was too much for the overwrought nerves of the sentinel. He gave a shriek of terror, fired wildly in the air, and sank fainting to the ground. Of course the camp was roused. Men jumped to their feet, and, rubbing their eyes, gazed around them in bewilderment.

It was not long before the truth dawned upon them. There lay the sentinel, insensible from fright, his discharged weapon at his feet, and the almost equally terrified donkey was in active flight, making the air vocal with his peculiar cries.

There was a great shout of laughter, in the midst of which Peabody recovered consciousness.

"Where am I?" he asked, looking about him wildly, and he instinctively felt for his scalp, which he was relieved to find still in its place.

"What's the matter?" asked the leader. "What made you fire?"

"I—I thought it was the Indians," faltered Peabody. "I thought I heard their horrid war-whoop."

"Not very complimentary to the Indians to compare them with donkeys," said Miles.

Lawrence Peabody was excused from duty for the remainder of the night, his place being taken by Miles and Tom in turn.
