It was a glorious morning as they set out a few minutes later at a slow canter across the prairie in the direction of the hills.
"Don't get too far away," Jeb shouted as they left.
"I'll race you to the top of the knoll," Sue challenged as soon as they were fairly away from the house.
It was merely an excuse for a burst of speed as Satan could easily out run the other horses and they were some distance in the rear when Bob drew rein on the top of the rise.
"He sure can run some," Sue declared as she rode up a moment later about fifty feet ahead of Jack.
"You said it," Bob agreed proudly.
For a few minutes they waited to give their mounts a breathing spell then Bob asked:
"Shall we keep on or circle around?"
"Oh, let's keep on," Sue said, "So long as we don't go into the hills we'll be safe enough."
So they rode on and on until the foothills were only a few hundred yards away. Then Bob drew up.
