"Let us see what they are eating," said the father. "Look into the trough, and you will see pieces ofbread, meat, bones, potatoes-waste of all kinds from the table. They eat anything that comes in their way.""Teacher says," added Fred, "that they like to grub in the ground for acorns, beech- nuts, and roots. Look at that fellow"s broad snout.
It is very hard, tough, and strong. It is meant for grubbing in the ground.""Yes," said Will, "and teacher told us to think about the cat, the dog, and the sheep. They are not meant to grub in the ground with their noses. They cannot do it. They need not do it, for they do not dig their food out of the ground.""If we could look into the pig"s mouth," said their father, "we should see that he has great grinding teeth behind like those of thesheep, as well as sharp-pointed teeth in front like thoseof the flesh-eaters."
"Yes," said Fred, "the pig lives on flesh as well as other food, because some of his teeth are meant for tearing flesh, and others for chewing and grinding. He can move his jaw, too, from side to side, as well as up and down.
