Referring to the book again, after the failure of the experiments upon his organ of combativeness, Dan found a few simple directions by which the reader could test, in a minor degree, the power of the mind over the sleeping body. One of the most simple was this: A person, before he goes to sleep, must resolutely make up his mind to wake at a certain hour in the morning. He must say to himself, "I want to wake at five o'clock--at five o'clock--at five o'clock; I _will_ awake at five o'clock--I will--I will--I will!" and continue to repeat the words and the determination over and over again until he fell asleep, with the resolve firmly fixed in his mind. If you do this, said the writer, you will awake at five o'clock. Dan tried this experiment the same night--and failed. He repeated it the following night, and the night following that, with the same result. His sleep was disturbed, but that was all. But on the fourth night matters were different. Five o'clock was the hour Dan fixed upon, and nothing was more certain than that on the fourth night Dan woke up at the precise moment. There were two churches in the immediate neighborhood, and, as he woke, Dan heard the first church-bell toll the hour. One, two, three, four, five. Each stroke of the bell was followed by a dismal hum of woful tribulation. Then the other church-bell struck the hour, and each stroke of that was followed by a cheerful ring, bright and crisp and clear. Dan smiled and hugged himself, and went to sleep again, cherishing wild hopes which he dared not confess even to himself. He tried the experiment on the following night, fixing on a different time, half-past three. Undaunted by that and many other failures, he tried again and again, until one night he awoke when it was dark. He waited anxiously to hear the clocks strike. It seemed to be a very long half-hour, but the church-bell struck at last. One, two, three, four. With a droning sound at the end of each stroke, as if a myriad bees, imprisoned in a cell, were giving vent to a long-sustained and simultaneous groan of entreaty to be set free; or as if the bell were wailing for the hour that was dead. Then the joyous church-bell struck One, two, three, four. A wedding-peal in each stroke; sparkling, although invisible, like stars in a clear sky on a frosty night. Dan went to sleep, almost perfectly happy.
