9. There would be a growl and a snap, and away would go the other dog over Lupo’s head, with a piece of his hide gone or some of his bones broken.

10. As Lupo could not be broken of this habit, whenever he went out his master would put a muzzle on him so he could not bite.

LESSON XIX.

HOW DOGS SEE AND SMELL.

1. I think John has something new to tell us about his dog to-day. Let us listen to him.

2. I have looked at my dog’s eyes, and I find that the pupil is round, like mine, and it does not shut up into a streak, as in a cat.

3. The dog does not see so well in the night as a cat, but his sense of smell is much more keen.

4. My uncle has a pointer-dog named “Grouse,” and one day I went out with them to hunt quails.
