"What do they do, for instance, Mr. Brown?"
"Well, for one thing, a lamb likes to practice jumping. You see, sheep don't belong on prairies, like cattle. Cattle belong on prairies the same as buffalo, but sheep don't; they belong on mountains; that's the reason the young ones are so handy with their hoofs. They like to climb and jump, but on a prairie there is n't any place to jump off of. Well, maybe some day a lamb will be galloping and cavorting around, and he 'll come across a hunk of rock salt that has been all licked off smooth on top and hollowed out. He 'll take a running jump at that and land on it with all four hoofs in one spot and then he'll take a leap off the top. Then, when he sees what a good circus actor he is, he will gallop right around and do it over again; and the rest of his gang will start in and follow him, because what one sheep does the rest have got to do. That way they get to running in a circle round and round and taking turns at jumping."
"How perfectly funny!" exclaimed Janet.
"That's the way they do. They run races and play 'stump-the-leader' and 'hi-spy' and 'ring-around-the-rosy.' Why, Miss Janet, if you were out here a little later on, you would think it was recess all the time."
"I wish I might be," said Janet.
"A lamb likes to be on the go," he continued. "Sheep really ain't lively enough for a lamb, so he has to go off and have his own fun. He 'll gallop around with a troop of other lambs and won't stop except long enough to go home for dinner."
"I don't see," said Janet, "how a lamb can go away like that and ever find his mother again, in such a crowd. They all look alike."
"That's easy enough. Every sheep's voice is keyed up to a different pitch; they all sound different some way or another. And every lamb has a little voice of his own."
"Yes, I've noticed that. But I did n't know there was any object in it. Or that they knew each other's voices."
"Oh, certainly they do. When a lamb gets hungry he whisks right around and runs into the flock and starts up his tune. She'll hear it and she'll start up too; and that way they'll keep signaling to each other. A lamb will run into a crowd of a thousand sheep and go right to his mother. When he has arrived, maybe she will smell him to make sure; and if he is all right, why—then it is all right."
