It was rather a favourite habit of his to punish himself by fines for bad behaviour. Later on in life, when he found it difficult to rise early in the morning, he resolved to give the servant half a crown every time he played the part of the sluggard. One morning he found himself reasoning in his own mind, whilst enjoying a warm, comfortable bed, that, after all, half-crowns were very acceptable to the poor woman who received them. But he made up his mind to put an end, once and for all, to such suggestions from the tempter; and resolved accordingly that, if he got up late again, he would throw a guinea into the Cam. He did it too. The next time he rose late he walked down to the river, and threw a hard-earned guinea into the water. It was worth while, nevertheless; for he never had to punish himself again for the same fault.
