than normal for a week.

On August 9 his aeroflitter carried him to a spot in Wyoming where Albert Cornwell and a spaceship waited.

The spaceship, itself, was a weak point, of course, since there were men who had sold it, men who had transported ft and helped prepare it for flight. All those men, however, led only as far as Cornwell, and Cornwell, Peyton thought- with the trace of a smile on his cold lips-would be a dead end. A very dead end.

On August 10 the spaceship, with Peyton at the controls and Cornwell-and his map-as passenger, left the surface of Earth. Its non-grav field was excellent. At full power, the ship's weight was reduced to less than an ounce. The micro-piles fed energy efficiently and noiselessly, and without flame or sound the ship rose through the atmosphere, shrank to a point, and was gone.

It was very unlikely that there would be witnesses to the flight, or that in these weak, piping times of peace there would be a radar watch as in days of yore. In point of fact, there was none.

Two days in space; now two weeks on the Moon. Almost instinctively Peyton had allowed for those two weeks from the first. He was under no illusions as to the value of homemade maps by non-cartographers. Useful they might be to the designer himself, who had the help of memory. To a stranger, they could be nothing more than a cryptogram.

Cornwell showed Peyton the map for the first time only after takeoff. He smiled obsequiously. 'After all, sir, this was my only trump.'

'Have you checked this against the lunar charts?'

'I would scarcely know how, Mr. Peyton. I depend upon you.'

Peyton stared at him coldly as he returned the map. The one certain thing upon it was Tycho Crater, the site of the buried Luna City.

In one respect, at least, astronomy was on their side. Tycho was on the daylight side of the Moon at the moment. It meant that patrol ships were less likely to be out, they themselves less likely to be observed.

Peyton brought the ship down in a riskily quick non-grav landing within the safe, cold darkness of the inner shadow of a crater. The sun was past zenith and the shadow would grow no shorter.

Cornwall drew a long face. 'Dear, dear, Mr. Peyton. We can scarcely go prospecting in the lunar day.' The lunar day doesn't last forever,' said Peyton shortly. There are about a hundred hours of sun left. We can use that time for acclimating ourselves and for working out the map.'

The answer came quickly, but it was plural. Peyton studied the lunar charts over and over, taking meticulous measurements, and trying to find the pattern of craters shown on the homemade scrawl that was the key to- what?

Finally Peyton said. The crater we want could be any one of three: GC-3, GC-5, or MT-10.'

'What do we do, Mr. Peyton?' asked Cornwell anxiously.

'We try them all,' said Peyton, 'beginning with the nearest.'

The terminator passed and they were in the night shadow. After that, they spent increasing periods on the lunar surface, getting used to the eternal silence and blackness, the harsh points of the stars and the crack of light that was the Earth peeping over the rim of the crater above. They left hollow, featureless footprints in the dry dust that did not stir or change. Peyton noted them first when they climbed out of the crater into the full light of the gibbous Earth. That was on the eighth day after their arrival on the moon.

The lunar cold put a limit to how long they could remain outside their ship at any one time. Each day, however, they managed for longer. By the eleventh day after arrival they had eliminated GC-5 as the container of the Singing Bells.

By the fifteenth day, Peyton's cold spirit had grown warm with desperation. It would have to be GC-5. MT-10 was too far away. They would not have time to reach it and explore it and still allow for a return to Earth by August 31.

On that same fifteenth day, however, despair was laid to rest forever when they discovered the Bells. They were not beautiful. They were merely irregular masses of gray rock, as large as a double fist, vacuum-filled and feather-light in the Moon's gravity. There were two dozen of them and each one, after proper polishing, could be sold for a hundred thousand dollars at least.

Carefully, in double handfuls, they carried the Bells
