"Yes, I see, boys: do you think that men had the first spades in the world?"

"Ah! now you are going to tell us something about tools among animals: that is good; we like to hear of that. What animal is it that has a spade?"

"Oh, a very common animal indeed in some parts of our country. The country people call it a woodchuk, and sometimes a ground-hog: its right name is the marmot; and as there are several sorts, ours is called the Maryland marmot, to distinguish it; but it is in New-York, Connecticut, New-Jersey. Pennsylvania, Virginia, and some of the other states, as well as in Maryland. This is rather a mischievous animal, and does harm to the clover-fields; but it is in making his house that he uses his spade."

"Then he digs his house in the ground. Uncle Philip?"

"Yes; he burrows, or digs his nest in banks of earth, or on the sides of hills; and he has sense enough to make the passage to the inside upwards, instead of downwards, so that water cannot run in. In digging soft earth he uses his fore-paws to loosen the dirt, for his fore-legs are very strong; and if the ground is hard he will use his teeth too. As he gets farther in, he throws the dirt with his fore-paws under his belly, and when he has a heap gathered, he balances himself on his fore-feet, and begins to throw it out with his spades."

"What are his spades, Uncle Philip?"

"His hinder feet, boys, which are very broad, and just fit to take up the dirt as a spade does, and to throw it from him: there is a skin which grows between the toes of his hinder feet, so that he can spread them out when he chooses, like a duck's foot."

"But, Uncle Philip, perhaps they are made so for the sake of swimming; the duck's are."

"That is a sensible thought, boys. Always think for yourselves; and when you make a mistake, try again: everybody is mistaken sometimes. Let it teach you to be modest and humble; but do not be afraid to think again. A person who is always thinking cannot always think wrong. Now you suppose the marmot's feet may be made like a duck's for swimming: let me tell you something else, and we shall see what you will think then. The marmot hates a rain as much as you would if you had no umbrella; he very seldom even drinks water, and then only a little; and you cannot drive him into a stream or pond; he is afraid of it. What do you think now?"
