They had traveled but a few miles in the calm clear light of morning when they saw not a quarter of a mile ahead of them thirty or forty beautiful antelope. They were cantering across the prairie, their little white cotton tails shining in the sunshine, the light gleaming on their pretty dappled sides. They were playing and leaping, and their curious antics made the boys shout with laughter.

"Wonderful chance to get an antelope," said Lige with shining eyes; but Joe shook his head. "Could you shoot one of those beautiful creatures?" he asked. "I swear I couldn't."

The antelope seemed to have but little fear of them, and cantered along for some distance, stopping now and then to crop the grass. After a time they raced away toward the south, and were lost to view.

It was now well on in August. Even at the early hour at which they had started there was a scorching wind blowing, and as the day advanced the sun beat down on the prairies from a cloudless sky with an intensity that promised a day of intolerable heat.

The family dispensed with every garment possible, and sat under the canvas covers fairly parching with heat, while the hot wind seemed fairly to scorch the prairies, and to burn and shrivel their skins.

Many times during the day they had to stop the horses, and at last Joe conceived the idea of making pads for their heads from the prairie grass, which he kept wet with water, brought from the well of the hospitable Wards.

It was toward three o'clock in the afternoon, at the very hottest part of the day, that Mrs. Peniman looking out of the front of the wagon suddenly exclaimed aloud.

"Why," she cried, "look, look, Joshua, there is a lake before us!"

Mr. Peniman, who was half-dozing on his seat, started wide awake.

"A lake?" he cried. "A lake in this country? Where?"
