“But why do you call him Hardshell?” asked Peter impatiently.
“Because instead of a coat of fur he wears a coat of shell,” replied Old Mother Nature, and then laughed right out at the funny expressions on the faces before her. It was quite clear that Peter and his friends were having hard work to believe she was in earnest. They suspected her of joking.
“Do—do you mean that he lives in a sort of house that he carries with him like Spotty the Turtle?” ventured Peter.
“It is a shell, but not like that of Spotty,” explained Old Mother Nature. “Spotty's shell is all one piece, but the Armadillo's shell is jointed, so that he can roll up like a ball. Spotty isn't a mammal, as are all of you and all those we have been learning about, but is a reptile. Hardshell the Armadillo, on the other hand, is a true mammal.”
“Well, all I can say is that he must be a mighty queer looking fellow,” declared Peter.
“He is,” replied Old Mother Nature. “He is about the size of Unc' Billy Possum, and if you can imagine a pig of about that size with very short legs, a long tapering tail, feet with toes and long claws and a shell covering his whole body, the front of his face and even his tail, you will have something of an idea what he looks like.
“He lives down in the hot Southwest where Piggy the Peccary lives. His coat of shell is yellowish in color and is divided in the middle of his body into nine narrow bands or joints. Because of this he is called the Nine-banded Armadillo. In the countries to the south of this he has a cousin with three bands and another with six.
“Hardshell's head is very long and he carries it pointed straight down. His small eyes are set far back, and at the top of his head are rather large upright ears. The shell of his tail is divided into many jointed rings so that he can move it at will.
“His tongue is long and sticky. This is so that he can run it out for some distance and sweep up the Ants and insects on which he largely lives. His eyesight and hearing are not very good, and having such a heavy, stiff coat he is a poor runner. But he is a good digger. This means, of course, that he makes his home in a hole in the ground. When frightened he makes for this, but if overtaken by an enemy he rolls up into a ball and is safe from all save those with big and strong enough teeth to break through the joints of his shell. He eats some vegetable matter and is accused of eating the eggs of ground-nesting birds, and of dead decayed flesh he may find. However, his food consists chiefly of Ants, insects of various kinds, and worms. He is a harmless little fellow and interesting because he is so queer. He is sometimes killed and eaten by man and his flesh is considered very good. He has from four to eight babies in the early spring. The baby Armadillo has a soft, tough skin instead of a shell, and as it grows it hardens until by the time it is fully grown it has become a shell.
“Now this finishes the lessons about the land animals or mammals. There are other mammals who live in the ocean, which is the salt water which surrounds the land, and which, I guess, none of you have ever seen. Some of these come on shore and some never do. To-morrow I will tell you just a little about them, so that you will know something about all the animals of this great country which is called North America. That is, I will if you want me to.”
