tartly, "You're only our bus driver, John. Keep to your astronautics and leave real science to us."
Then—the time of Pathfinder's return from Delta Sextans V was fast approaching—Grimes was unable to spend much, if any, time on the river bank. The preliminaries to shutting up shop were well under way with specimens and records and unused stores to be packed, with the propulsion unit of the landing craft to be checked. Nonetheless, Grimes was able to check up now and again on Snuffy's progress, noted with satisfaction that the native was making out quite well.
In all too short a time the cruiser signaled that she was establishing herself in orbit about IV, also that the Captain himself would be coming down in the pinnace to inspect the camp. Grimes worked as he had never worked before. He received little help from the others—and the scientists were such untidy people. There should have been at least six general purpose robots to cope with the mess, but there was only one. Grimes. But he coped.
When the pinnace dropped down through the grey overcast the encampment was as near to being shipshape and Bristol fashion as it ever could be. Grimes barely had time to change into a clean uniform before the boat landed. He was standing to attention and saluting smartly when Captain Tolliver strode down the ramp.
Tolliver, after acknowledging the salute, actually smiled. He said, "You run a taut shore base, Mr. Grimes. I hope that when the time comes you will run a taut ship."
"Thank you, sir."
Grimes accompanied the Captain on his rounds of the encampment, the senior officer grunting his approval of the tidiness, the neatly stacked items all ready to be loaded into the landing craft and the pinnace in the correct order. And the scientists—thank the Odd Gods of the Galaxy!—were no longer their usual slovenly selves. Just as the camp was a credit to Grimes, so were they. Maggie Lazenby winked at him when Captain Tolliver was looking the other way. Grimes smiled back gratefully.
Said Tolliver, "I don't suppose that you've had time for any projects of your own, Mr. Grimes. Rather a pity . . ."
"But he has found time, sir," said the Ethologist.
"Indeed, Dr. Lazenby. What was it?"
"Er . . . We were busy ourselves, sir. But we gained the impression that Mr. Grimes was engaged upon research of some kind."
"Indeed? And what was it, Mr. Grimes?"
Grimes looked at his watch. It was almost time. He said, "I'll show you, sir. If you will come this way. Along the river . . ."
"Lead the way, Mr. Grimes," ordered Tolliver jovially. In his mind's eye Grimes saw the glimmer of that half ring of gold braid that would make him a Lieutenant Commander. Promotions in the Survey Service were the result of Captain's Reports rather than seniority.
Grimes guided Tolliver along the river bank to where the trail opened from the jungle to the little bay. "We wait here, sir," he said. He looked at his watch again. It shouldn't be long. And then, quite suddenly, Snuffy led the way out of the jungle. He was proudly carrying his bone club, holding it like a sceptre. He was flanked by two smaller humanoids, each carrying a crude bone-weapon, followed by two more, also armed. He went to the fruit plants, tore at them greedily, wasted more than he ate. The others looked on hungrily. One tried to get past the guards, was clubbed down viciously. Grimes gulped. In a matter of only three days his experiment was getting out of hand.
"I have studied Captain Loveil's films of these beings," said Tolliver in a cold voice. "Are you responsible for this?"
"Yes, sir. But . . ."
"You will be wise to apply for a transfer, Mr. Grimes. Should you continue in the Service, which is doubtful, I sincerely hope that you discover the legendary fountain of youth."
"Why, sir?"
"Because it's a bloody pity that otherwise you won't be around to see the end results of what you started," said Tolliver bitterly.
