And as the remains of this prehistoric monster, that had lived, walked, eaten and fought on earth from ten to twenty-five million years ago, rose out of the pit, even the workaday cowboys could not repress a cheer.

"That's the idea, boys!" cried Professor Wright, who was quite a different person, now that his work was crowned with success. "I feel like cheering also! This is the culmination of my life's ambition, and that of my helper, Professor Blair!"

When the wounded had been cared for and the prisoners had been sent to the nearest jail, the remains of the skeleton of the Triceratops, part of the bones imbedded in rock, were carefully hoisted out and laid to one side. When I tell you that the skull, alone, of one of these monsters, imbedded in rock, weighed, when boxed for shipment to a museum, over three tons, you may form some idea of the magnitude of this sort of relic collecting, and understand why many powerful steers were needed, with tackle, to raise specimens out of a deep pit.

That the boy ranchers were intensely interested in the remaining work of restoring to science the lost Triceratops, goes without saying. When it was made plain that the two professors and their men were not cattle rustlers, Mr. Merkel gave them every assistance in his power, assigning some of his cowboys to help with the labor of excavating the remaining bones, not all of which could be found.

For it is rare that a complete skeleton of these monster Dinosaurs is recovered. While our western states, in certain places, are rich in fossil remains, there is very seldom a complete skeleton unearthed. At best there are but a few bones, or the impressions of bones, in the sandstone rocks or shale. But from these bones, from the impressions of those that have been eaten by time, and by their knowledge of what sort of anatomy was needed to keep these wonderful creatures on earth, it is possible for scientists to almost completely and perfectly restore them, in some medium like papier-maché.

"We shall be the envy of all our colleagues!" declared Professor Wright, as the work progressed from day to day, the boy ranchers becoming eager helpers. Professor Wright and Professor Blair labored with their men, and as hard.

There was one exception to this—Silas Thorp. He of the sour face and hangdog manner, it was discovered, had acted with Del Pinzo in stealing cattle, intending to sell them for their own profit, after they had "borrowed" the animals from Diamond X ranch, letting the two professors think the steers had legitimately been "hired."

Silas made his escape during the fight, but Del Pinzo and most of his men were captured. Not all of the professors' employees were confederates of the Greasers, Del Pinzo and Silas Thorp. Some were as ignorant as the scientists themselves that anything wrong was going on. These men were soon freed, and helped in the work of excavating the Triceratops.

There really were some cattle rustlers engaged in operations around Diamond Z ranch when Nort and Dick happened to come on their visit. This fact was discovered later when some of the cattlemen organized a posse, and after a fight, in which several on both sides were slain, arrested a notorious gang.

It was Del Pinzo who had tried to rope Dick that night, hoping, it was surmised, that in the confusion, he might be able to steal some steers.
