Fors did not stop to explore any more of the shops, but he made mental notes about those which might be worth a second visit. It was slow work breaking a trail through the blocked streets, and the heat reflected back from the buildings brought sweat dripping from his face to plaster his clothing to him. He had to mount again as his leg began to ache, and the hollow feeling in his middle grew worse. Lura protested—she wanted to get away from this wilderness of stone, into the fields where one could hunt.

Three hours of steady traveling brought them through to the edge of the enchanted wood, for that was what it seemed. It was a band of living green cutting across the pitiless heat and barrenness of the ruins. Once it had been a park, but now it arose a true forest which Lura welcomed with an open meow of delight. The mare whinnied, bursting through bushes until she came into what was undoubtedly a game trail leading down a gentle slope. Fors dismounted and let the mare go on, her pace now a trot. They reached the end of the trail, a lake. The mare stood, nose- and hock-deep, in the green water. Long red-gold fish swam away from the disturbance she caused.

Fors dropped down on a wide stone and pulled off his boots to dabble bis burning ieet in tbe coolness. Tbeie was a freeze across the water which dried his damp body and lifted the leaves of the wild shrubs around them. He looked across the lake. Opposite him there was a flight of broad white steps, cracked and moss-grown, and he caught a glimpse of a building at their head. But that could be explored later. Just now it was good to sit in the cool. The mare came out of the lake and tore up mouth-fuls of the long grass. A duck quacked and fled from under her hoofs, sailing out on the water, swimming energetically toward the steps.

The evening was long, the twilight soft about the hidden lake. While there was still light enough to see Fors ventured into the tall, pillared building at the head of the stairs and discovered that his luck was still holding. It was a museum—one of those treasure houses which rated very high on the Star Men’s list of desirable finds. He wandered through the high-ceiled rooms, his boots making splotchy tracks in the fine dust crisscrossed with the spoor of small animals. He brushed the dust from the tops of cases and tried to spell out the blotched and faded signs. Grotesque stone heads leered or stared blindly through the murk, and tatters of powdery canvas hung dismally from worm-eaten frames in what had once been picture galleries.

But the dark drove him out to shelter in the forecourt. Tomorrow would be time to estimate the worth of what lay within. Tomorrow—why, he had limitless time before him to discover and assess all that this city held! He had not even begun to explore.

It was warm and he allowed his cooking fire to burn down to a handful of coals. The forest was coming to life. He identified the bark of a questing fox, the mournful call of night birds. In the city streets he could almost imagine the gathering of wistful, hungry ghosts seeking what was gone forever. But here, where man had never lived, it was very peaceful and like the glens of his own mountain land. His hand fell on the pouch of the Star Men. Had Langdon actually walked here before him, had it been on a return trip from this place that his father had been killed? Fors hoped that was true—that Langdon had known the joy of proving his theory right—that his map had led him here before his death.

Lura appeared out of the shadows, padding lightly up the mossy steps from the water’s edge. And the mare moved in without urging, her hoofs ringing on the broken marble as she came to join them. It was almost—Fors straightened, regarded the gathering night more intently —almost as if they feared an alien world enough to seek company against it. And yet he did not feel the unease he had known in those other ruins—this slice of woodland held no terrors.

Nevertheless he roused and went to gather as much wood as he could find and he worked with mounting haste until it was too dark to see at all, ending with a pile of broken branches and storm drift which might have been gathered to withstand a siege. Lura watched him —and beyond him—sitting sentry-wise at the head of the stairs. Nor did the mare move again into the open.

At last, his hands shaking a little with fatigue, the odd drive still urging him to some sort of effort, Fors strung his bow and set it close to hand, loosened his sword in its sheath. The wind had gone down. It was almost sultry. Above the water the birds had ceased to wheel.

There was a sudden thunder clap and a flash of violet lightning crossed the southern sky. Heat lightning, but there might be another storm on the way. That was probably what made the air seem electric. But Fors did not deceive himself. Something besides a storm was brooding out in that night.
