"'Cause I'm an Indian!" answered Russ. "You have to yell that way, too. Indians always yell."
"Oh, all right. I'll yell," said Laddie. "I thought maybe you'd hurt yourself. Oh, hoo! Doodle-doodle-oo!" he shouted.
"Hey, that's no way to yell like an Indian!" objected Russ.
"'Cause it sounds more like a rooster crowing. Yell like this: 'Wah-hoo! Zoo! Zoop! Wah! Wah!'"
"Oh, you want me to yell that way. Well, I will," said Laddie. And he yelled as nearly as he could like his brother.
So the two boys rode on and on, crossing the plain this way and that, so as not to get too far from the house. They could see the ranch buildings each time they got on top of the little knolls that were scattered here and there over the plain.
"Let's have a race!" suggested Laddie, after a bit. "I don't guess we are going to see any of Uncle Fred's cattle over here to make believe they're buffaloes. Let's have a race!"
"All right!" agreed Russ. "And I don't have to give you any head start this time, 'cause your pony's legs are going to run, and not your legs, and your pony's legs are every bit as long as my pony's. So we can start even."
"Yes," said Laddie, "we can start even."
