"No, indeed, sir," retorted the professor seriously, as his suitcase went bounding over the platform, which was formed of sun-baked earth. "I have books. The idea of such a question. Why should I want to carry bricks about with me, although the ancient Egyptians——"

By this time the porter was far out of hearing, and the last car of the train had whizzed by. Before the professor could conclude his speech, the suitcase—as if to prove his contention as to its contents by actual proof—burst open, and out rolled several massive volumes. The few loungers, who had gathered to watch the train come in, set up a roar of laughter as the professor—his coat flaps flying out behind him like the tail of some strange bird—darted after his beloved volumes.

"That's what you might call a circulating library!" grinned Jack, as the books bounded about with the impetus of their fall.

"I thought it was a Carnegie Car, you see——" began Ralph, when a sudden shout checked him. He glanced up in the direction from which it had come. A dust-covered buckboard, in which sat a tall, bronzed man in plainsman's clothes, was dashing toward them. The two buckskin ponies which drew it were being urged to their utmost speed by the driver, to whom Jack Merrill was already waving his hand and shouting:

"Hello, dad!"

In the meantime the professor was groping about on the platform, picking up his scattered treasures, and all the time commenting loudly to himself on his misfortune.

"Dear, dear!" he exclaimed, picking up one bulky volume and examining it with solicitude. "Here's a corner broken off Professor Willikin Williboice's 'The Desert Dwellers of New Mexico, With Some Account of the Horn Toad Eaters of the Region.' And what have we here? Eheu! the monumental work of Professor Simeon Sandburr, on the 'Fur-Bearing Pollywog of the South Polar Regions,' is——"

"Slightly damaged about the back!" broke in a hearty voice behind him. "But never mind, professor; the pollywogs will grow up into frogs yet, never fear. We'll soon have those volumes mended; and now let me introduce myself, as my son Jack seems unable to do so. My name is Jefferson Merrill, the owner of Agua Caliente Ranch."

"Delighted to meet you, sir," said the professor. "Proud to encounter a man whose name is not unknown to science in connection with his efforts to uncover something of the history of the mesa dwellers of this part of the world."

"Whose relics, if my son informed me rightly in his letters from school in the East, you have come to study, professor."
