"They are prairie dogs," answered Mr. Peniman. "We are passing through what is called a 'prairie dog town.' I have read of them many times, but have never seen them before."

They had stopped the teams, and the family all scrambled out of the wagons to see this strange and novel sight of a "town" in which nothing lived but prairie dogs.

"Why, just see," cried Joe, "there are millions of them! Just look at that fellow over there, Ruth, sitting up on the roof of his house scolding at us!"

And truly there did appear to be millions of them. The whole surface of the ground as far as they could see was dotted over with the queer little dome-like houses, made of the clayey soil of the prairies thrown up into small heaps or mounds; and on each sat a small reddish-grey animal, a little larger than a squirrel, with tail cocked up saucily over their backs, and paws folded demurely across their fat little stomachs, gazing with bright, bead-like eyes at the intruders, of whom they did not seem to be in the least afraid. On each side of the face were pouches, in which they carry out the dirt when burrowing the holes in which they live, and in which they pouch nuts, roots, and other dainties. They seemed filled with curiosity, and as they came swarming up out of their holes to sit on the tops of their houses, they made a peculiar barking noise, something like the bark of a young puppy.

This amused the children immensely. "How deep are their holes, Father?" asked Sam.

"I have read that they are tunneled back long distances, and that many of the underground passages connect the mounds with one another. I have also read," he continued with a twinkle in his eyes, "that a prairie dog, an owl, and a rattlesnake lives in every hole."

"A rattlesnake?" cried Ruth. "Wouldn't it bite the prairie dogs?"

Joshua Peniman laughed. "Well, I don't know, Ruth, that is what I read; but my own opinion is that as the main business of little Mrs. Prairie Dog is to keep snakes and other varmints from eating her little ones I hardly think she would tolerate a rattler in her house. But come now, jump in, we must not spend any more time here. No doubt there are many just as interesting and curious things to see farther on."

They stopped early that night on account of the heat, wanting to save the horses all they could. A strong wind came up about sundown, which soon grew to be a gale, and which almost blew them off their feet as they scampered about on the prairie trying to find something of which to make their fire.

It was their first taste of the "Nebraska zephyrs," of which they were to see so much later on, and it kept the whole family busy chasing about after hats and bonnets, brooms, dish-pans, and all sorts of things that blew out of the wagons.
