He watched the flaring light until he was satisfied that Trolla was making for space and not for another landing place. Then he returned to sleep.

Just to be sure, Quasmin remained in the hills two more days, until his supplies ran low and he thought it might be comfortable to return to the hut. He made his way back warily, lest Trolla should have left some sort of trap.

At the shack, he found nothing but his own things, so he hiked through the purplish shrubbery to the landing spot. To his surprise, he discovered that Trolla had left a number of crates behind. He sat down to think that over.

When no explanation occurred to him, he went to the wreck of his own ship. In the partly stripped control room were a few instruments that still functioned when he hooked up batteries to power them.

"Might be smart to see if he's in orbit," he muttered. "Maybe he thinks he can soften me up by leaving presents."

Emerging an hour later, he looked puzzled. As much by luck as by skill and accuracy, he had succeeded in picking up Trolla's ship on the rangefinder. The instrument was not meant to operate efficiently through an atmosphere and Quasmin was no expert in its use; but it definitely showed Trolla was heading out-system.

"Well, then, I might as well see if he left a bomb," decided Quasmin.

He approached the crates close enough to read the stenciled labels. Scowling in bewilderment, he set about opening them. Just as the lettering indicated, he found an assortment of electric motors, equipment for building a new generator that could be powered by his waterwheel, and even a supply of glow-panels for light if he should get an electrical system into operation.

There was also a chest of tools and parts, and several boxes of grain and vegetable seeds. The prize of all was a small, three-wheeled, battery-powered vehicle that looked just large enough to pull a homemade plow.

The man sat on an open crate and burst into hysterical laughter.
