“And they were indeed Darius's men. Men of that Persia which had been dead for millenniums. There was no mistaking them, with their high, covering shields, their great bows, their javelins and armor.

“They passed; we doubled. We built no fires that night—and we ought to have turned the pony loose, but we didn't. It carried my instruments, and ammunition, and I felt we were going to need the latter.

“The next morning we caught sight of another band—or the same. We turned again. We stole through a tree-covered plain; we struck an ancient road. It led south, into the peaks again. We followed it. It brought us here.

“We crossed. As we were about to enter the cleft there issued out of it a most unusual and disconcerting chorus of sounds—wailings, crashings, splinterings.”

I started, shot a look at Dick; absorbed, he was drinking in Ventnor's every word.

“We made the best time we could back to the fortress. And when next we tried to go through the hollow, to search for another outlet—we couldn't. You know why,” he ended abruptly.

“But men in ancient armor. Men like those of Darius.” Dick broke the silence that had followed this amazing recital. “It's incredible!”

“Yes,” agreed Ventnor, “isn't it. But there they were. Of course, I don't maintain that they WERE relics of Darius's armies. They might have been of Xerxes before him—or of Artaxerxes after him. But there they certainly were, Drake, living, breathing replicas of exceedingly ancient Persians.
