"I say so still. Look!" he broke off, pointing to the sea.

A commotion was going on beneath its surface. Their grisly shapes vivid in the disturbed phosphorescence, drawing a wake of flame behind them, rushed two great sharks. Hither and thither they darted, every detail of their ugly forms discernible on the framing of the phosphorescent blaze, even the set glare of the cruel eye; and, no less nimble in swift doubling flashes, several smaller fish were trying to evade the laws of nature—the absorption of the weakest, to wit. There was something indescribably horrible in the fiery rush of the sea-demons beneath the oily blackness of the tropical waters.

"How awful! how truly awful!" murmured Lilith, with a strong shudder of repulsion, yet gazing as one fascinated at the weird sight.

"Yet it is the perfection of an object lesson, one that comes in just in time to point the moral to my answer," he said. "If those fish, now in process of being eaten, were caught and kept in an aquarium tank, it might be more monotonous for them than furnishing fun and food to the first comer in the way of bigger fish. Possibly they might yearn for the excitement of being harried, though I doubt it. That sort of philosophy is reserved for us humans. If we knock our heads against a brick wall we howl; if we haven't got a brick wall to knock them against we howl louder."

"And the moral is?"

"Dona nobis pacem."

"I see," she said at last, for it took her a little while to thoroughly grasp the application, partly distracted as her thinking powers were in trying to find a deeper meaning than the one intended. "Yet peace is a thing that no one can enjoy in this world. How should they when the law of life is struggle—struggle and strife?"

"Precisely. That, however, is due to the faultiness of human nature. The philosophy of the matter is the same. Its soundness remains untouched."

"Yet you are not consistent. You were implying just now that, failing a brick wall to knock our heads against, we started in search of one. Now does not that apply to those who go out into the world—to the other end of the world—instead of remaining peacefully at home?" she added, a sly sort of "I-have-you-there" inflection in her tone.

"Pardon me. My consistency is all right. Begging a question will not shatter it."
