"I rely on the barricades," said David, "and don't see the necessity of any arms; for I don't see how we're going to be attacked. If we are, I suppose I can use my knife, like Frank." "Well," said Bob, "I've given my knife away, and I'll have to take a chair." "Wal," said Uncle Moses, "I've got a razor, an it's pooty ugly weepin in the hands of a savage man--a desprit ugly weepin." "And now let's go to bed," said David, do. said Bob. do. said Clive. do. said Frank. "Yes, boys, that's about the best thing we can do," said Uncle Moses, decisively. CHAPTER XXIII. _The sleepless Watch.--The mysterious Steps.--The low Whispers.--They come! They come!--The Garrison roused.--To Arms!

In this way they had disposed of themselves. Bob was very wakeful. The beds were father unprepossessing, and consequently they had all retired without altogether undressing themselves; but in spite of this comparative discomfort they soon fell asleep. Bob alone remained awake. He tried all he could to overcome his wakefulness. He resorted to all the means for producing sleep that he had ever heard of or read of. He tried counting, and went on counting and counting tens, and hundreds, and thousands. He counted fast, and he counted slow. In vain. Counting was useless, and when he had reached as high as four thousand seven hundred and thirty-seven, he gave it up in disgust. Then he tried another infallible recipe for sleep He imagined, or tried to imagine, endless lines of rolling waves. This also was useless. Then he tried another. He endeavored to imagine clouds of smoke rolling before him. This was as useless as the others. Then he tested ever so many other methods, as follows:--
