Faithful as dogs are in general, I am sorry to have to record an instance to the contrary.

A watch-dog, whose special duty was to remain at his post during the night, found that his collar was sufficiently loose to allow him to withdraw his head from it whenever he pleased. He acted as some human beings do whose right principles do not fit tightly to their necks—slipping out of them at the very time they ought to keep them on. The dog was, however, sagacious enough to know that if he did so during the day he would be seen by his master, when to a certainty the collar would be tightened. But no sooner did night arrive, and the lights began to disappear from the windows, than he used to slip his head out of his collar, and roam about the neighbouring fields, sometimes picking up a hare or rabbit for his supper.

Knowing also that the blood on his mouth would betray him, he would, after his banquet, go to a stream and wash it off. This done, he would return before daybreak to his kennel, and slipping his head into his collar, lie down in his bed, as though he had remained there on the watch all the night.

Now I must beg my young readers to remember, should they be tempted to do what is wrong, that however well-behaved they may contrive to appear before their friends and acquaintances, in their own mind there will always be the unpleasant feeling arising from the consciousness of doing a guilty action.
