He paused, and looked at Stump. That broad-beamed navigator emptied his glass again, and gazed into it fixedly, apparently wondering why champagne was so volatile a thing. Tagg followed the skipper's example, but fixed his eyes on the bottle, perhaps in calculation. Royson, deeming it wise to hold his tongue, contented himself with closing the medicine chest, and thus making it possible for von Kerber to sit down. The latter was obviously ill at ease. Although he was the master of these three men, he was their inferior in individual strength of character. But he was a polished man of the world, and he promptly extricated himself from a difficult position, though Royson, at least, detected the effort he was compelled to make. "I see you are thinking that one bottle does not go far among four of us, Mr. Tagg," he exclaimed, with a pleasantly patronizing air. "Kindly tell the steward to bring another, Mr. King. And some cigars. Then we can discuss matters at our ease. And will you make sure that we are not overheard? What I have to say is meant for the ship's officers alone at this moment, though, when the time for action comes, every man on board must be with us absolutely." Dick summoned the steward, and ascertained that the watch were quietly chatting and smoking forward, whereas the Baron's stateroom was situated aft. The delay enabled von Kerber to collect his thoughts. When he resumed the promised disclosure, his voice was under control, and he spoke with less constraint. "It is probable that you gentlemen are not familiar with the history of Egypt," he said, "but you may take it from me that the facts I now lay before you are accurate. At one time, about the beginning of the Christian era, the Romans were all-powerful in the Nile delta. They pushed their stations a long way south, almost to the borders of Abyssinia, but it is important, to remember that they followed the lines of the river, not the sea. In the year 24 B.C., the Roman Governor, hearing of the great wealth of a people called the Sabaeans, whose country lay in Arabia, in the hinterland of Mocha and Aden, sent an expedition there under the command of Aelius Gallus. This legion is historically reported to have met with reverses. That is true, in the sense that its galleys were beset by a terrible storm on the return voyage. Though the Red Sea is usually a fair-weather lake, you can have a stiff blow there at times, I believe, Captain Stump?" Thus appealed to, Stump had to open his mouth. "I've known it blow like sin," he said. "Isn't that so, Tagg?" "Wuss nor sin, cap'n. Ord'nary manslaughter isn't in it with a nor'-east gale on a dark night off them islands north o' Perim."
