The old cuss was lonely, Cooper told himself. That was why he hung around like a homeless dog—except that he was too big and awkward to have much pet-appeal and, more than likely, his temper was unstable.

The afternoon sun was pleasantly warm and the air, it seemed to Cooper, was the freshest he had ever smelled. It was, altogether, a very pleasant place, an Indian-summer sort of land, ideal for a Sunday picnic or a camping trip.

The breeze was just enough to float out from its flagstaff before the tent the national banner of Mastodonia—a red rampant mastodon upon a field of green.

"You know, Johnny," said Adams, "there's one thing that worries me a lot. If we're going to base our claim on precedent, we may be way off base. The old explorers always claimed their discoveries for their nations or their king, never for themselves."

"The principle was entirely different," Cooper told him. "Nobody ever did anything for himself in those days. Everyone was always under someone else's protection. The explorers either were financed by their governments or were sponsored by them or operated under a royal charter or a patent. With us, it's different. Ours is a private enterprise. You dreamed up the time unit and built it. The three of us chipped in to buy the helicopter. We've paid all of our expenses out of our own pockets. We never got a dime from anyone. What we found is ours."

"I hope you're right," said Adams uneasily.

Old Buster had moved out from the grove and was shuffling warily toward the camp. Adams picked up the rifle that lay across his knees.

"Wait," said Cooper sharply. "Maybe he's just bluffing. It would be a shame to plaster him; he's such a nice old guy."

Adams half raised the rifle.

"I'll give him three steps more," he announced. "I've had enough of him."
