By then it had largely ceased. Only occasionally did one of the vessels loose a single cannon shot. The rest of the time they spent in tacking back and forth and in running up close to the very edge of the island.

"I think they are trying the temper of the island's inhabitants," Green said. "They don't know whether the woods conceal a hundred savages or a thousand, or whether they're armed with cannons and muskets or just with spears. They want to draw fire, so they can get an estimate of what they're facing."

He turned to Miran. "Which reminds me, why is it that the natives don't use guns? They must have a chance to get their hands on many from the wrecks."

The fat merchant shrugged and rolled his one good eye to indicate that he didn't really know but was making a guess.

"Probably they've a taboo against using firearms. Whatever the reason, they're evidently suffering because they neglect them. Look how few they are. Only fifty men! They must have lost quite a few through raids from other savage tribes, both from those who live upon the plain itself and from those who live on other roaming islands. They're down to the point now where they must die out within a generation, even without help from such as those," he said, pointing to the Ving 'rollers.

"Yes, and I suppose that during the daytime, when the island is stopped, grass cats and dire dogs board it. These must take their toll of the humans."

He gazed again at the red sails and wheels of the Vings. "I'd think that those pirates would take every island they could and would use them as bases from which to operate."

"They do," said Amra. "For a generation now the Vings have been scouring the plains, locating the islands and exterminating the savages on them. Then they've fortified the islands, so that you might say that today the Xurdimur is dominated by them. But there's a drawback to an island as a harbor. No large 'roller may get very close except in the daylight. They have to put out to grass every night and follow their base at a safe distance until dawn. However, though the Vings are well established on many roamers, they're often attacked by the navies of various nations and sometimes driven off. Then the nation that takes possession of the island has a nice little base. And, of course, quite often they use it to launch their own piratical ventures against the craft of countries at peace with them.

"Oh, the Xurdimur is a land where every man's hand is against the other, and the devil take the ones with short sail! A man may make his fortune or break his heart, all in a night's work. But, then, you know that only too well."

Green interrupted, "We'll leave them, and the natives, too, when moonlight gets here. I only hope that there aren't other Ving craft in the neighborhood."
