It was the third day of this young Greaser's appearance in the fossil excavations, and coming close to the end of the week, which period of grace had been allowed Mr. Merkel by the court. Unless the deeds were soon produced the sheep would scatter over the Spur Creek lands and this would mean the beginning of the end for the cattle men.

Suddenly the comparative quiet of the fossil camp was broken by loud yells, and there seemed much excitement in a place where Professor Wright had been examining earth and rocks as the debris was deposited from an excavation.

The ragged youth, who had said he came to take the place of his ill brother, raced over the ground toward the excited group. He found the professor gazing eagerly down into a sort of cave that had been discovered when the digging reached a certain depth.

"Look out there now! Be careful!" cautioned the scientist. "I think we have found it. Here, you look intelligent!" and he motioned to the Greaser youth whom Del Pinzo had questioned. "Get down in there and make the opening a little wider so I can see what we've come upon. But be very careful. If there are bones we don't want to break them. Perhaps you'd better tell him, Del Pinzo," suggested Professor Wright. "He probably doesn't understand my English."

Thereupon Del Pinzo loosed a string of Mexican Spanish, at which the youth nodded, and proceeded to enlarge the opening to the small underground cavern.

As the light of day was allowed to enter, Professor Wright leaped down into the hole and stood almost at the side of the youth. Then, suddenly, the scientist cried:

"I've found it! I have discovered it! The gigantic Brontotherium! Success at last!"

And as the youth stepped aside to allow the scientist to enter and gaze upon the immense fossil bones which had just been laid bare, the youth looked at Del Pinzo, hastening across the camp ground, murmured:

"I, too, have found it! Success at last!"
