That the weird cry was not repeated in no wise detracted from its startling character; but although profound silence followed, it did not remain long unbroken, for a few minutes later there came the sound as of great wings sweeping hither and thither. And scarcely had this sound died away when it was succeeded by others—low moans, sighs, whistlings, grunts, bellowings, rustlings, splashings—some from a considerable distance, others apparently close at hand; some obviously from the land to the rear of the party, and others quite as obviously from the water in their front. And, most disturbing consideration of all, every one of them was absolutely unfamiliar, therefore in some vague, undefinable fashion, the more alarming. This effect was quickly made manifest by the agitated murmurings of the Indians, and the haste with which they replenished the dying fire, heaping on fuel with such a lavish hand that, for the space of a few yards all round the blaze, the light was almost as brilliant as that of day.

“Gee!” exclaimed Earle, as the weird sounds multiplied on all sides, “what would I not give for a full moon and a clear sky, just now. Bet your life, Dick, there are some very queer scenes being enacted all round us at this moment, had we but light to reveal them. I have come to the conclusion that this swamp is unique in many respects. By some freak of nature, things here are entirely different from what they are elsewhere. Even the vegetation is new and strange to me; and I am convinced that it is also the home of many forms of animal life unknown elsewhere. The exasperating part of the whole thing is that most of the creatures inhabiting it seem to be of nocturnal habit, hiding themselves during the day, and only emerging into the open at night. Just listen now to the hubbub of sound all about us. Why, the place must be fairly teeming with life! And, by a perverse combination of circumstances, we can see nothing of it—Ah! thank goodness, the lightning is becoming more vivid. I would give a good round sum for a real first-class thunderstorm; and, by ginks! I believe we are going to have it.”

It seemed quite probable, for as though in response to Earle’s ardently expressed desire, a brilliant flash of sheet lightning flickered out of the now rapidly rising bank of cloud over the distant hills, illumining the landscape for the fraction of a second, during which a momentary glimpse was afforded of certain strange forms dotting the waters of the lagoon; but the illumination was too brief to leave anything more than the most vague impression of those forms upon the retina of the observers. The glimpse, however, transient as it was, revealed enough to stimulate their interest and curiosity to the highest pitch, and the two friends, with their rifles grasped ready for instant action, sprang to their feet and stood eagerly awaiting further revelation with the next flash of lightning, while the Indians, cowering round the roaring fire on the summit of the knoll, were visibly suffering the extremity of terror.

Then, while the two friends stood together awaiting the coming of another lightning flash, with King Cole quivering and shivering at their feet, a huge shape, elusively revealed in the flickering firelight, slowly emerged from the intense darkness overshadowing the lagoon, ponderously splashing through the shallows toward the beach—and toward the two white men, a pair of enormous eyes, glistening in the uncertain light of the flames, being all that could be distinctly seen. The thing— whatever it may have been—was not more than ten yards distant when first seen, and there was a gleam of such deadly malignancy in those two glistening eyes, and a suggestion of such implacable purpose in the ponderous movement of the imperfectly seen bulk, that Earle and Dick, taken completely unawares by its sudden appearance, incontinently flung up their rifles and fired, at the precise moment that King Cole, utterly demoralised by the weird apparition, sprang to his feet and fled, snarling, to the rear. The two rifles spoke as one, and instantly following the whip-like reports, the double clap of the bullets was heard—not a dull sound like that of a bullet striking yielding flesh, but a sharp crack, suggesting the impingement of lead upon unyielding bone; there was a frightful bellowing roar, a terrific splash, the spray of which flew over and far beyond the two white men, and the thing was gone.

“Well, ‘shiver my timbers!’ as you sailors are supposed to remark,” exclaimed Earle in tones of ineffable disgust. “If that doesn’t beat the band! Oh, Dick Cavendish—and Wilfrid Earle, you—you twenty-volume unabridged fools, why on earth couldn’t you have waited another two or three seconds before shootin’ and so have made sure of getting the brute? Kick me, Dick, and I’ll kick you, for we both deserve it! It was the chance of a lifetime, and we flung it away by being over-eager. I’m ashamed of you, Dick—and a blamed sight more ashamed of myself; for I am an old hand at this sort of thing, while you are comparatively fresh at it, and therefore there is some sort of excuse for you, while there is none for me.”

“But we hit him,” remonstrated Dick. “What more do you want?”

“Hit him!” retorted Earle, disgustedly. “Of course we hit him; we couldn’t help hitting him. He was as big as a house! But, my gentle boy, that wasn’t enough. We wanted to kill him, so that we might have a chance to see what he looked like. Hit him! Yes; we hit him on his skull, and the blows sounded as though his head was encased in five-inch Harveyized armour plate! If we had waited five seconds longer, we should have had a good view of him and been able to shoot him through the heart—if he happens to possess such an organ.”

“That’s all very fine,” retorted Dick. “But I’ll bet that if we had waited the extra five seconds, you would still have aimed to hit him fair between the eyes—as I did.”

“Well—yes, I guess I should,” returned Earle, his vexation suddenly evaporating. “As a matter of fact, that is the precise spot I aimed at. And as you say that you did also, we will hope that one at least of our bullets got home, and that to-morrow morning, we shall find him floating dead out there in the offing waiting to be inspected. Anyway, there is no sense in crying over spilt milk; and who knows what chances may still be in store for us. And now, Dick, while your memory is still fresh, have the goodness to describe to me exactly the impression left upon your mind by what you saw. Gee! what a time the inhabitants of this swamp seem to be having. The row is growing worse than ever.”

Dick dutifully responded to his friend’s request, but alas! his description amounted to very little more than the bald statement that the thing struck him as possessing a body about as bulky as an elephant, standing upon disproportionately short legs; that the eyes were as big round as dinner-plates; that they glared with a most unholy malevolence; and that they were spaced about thirty inches apart. These details, such as they were, corresponded with the impression produced upon Earle, who forthwith proceeded to jot down the meagre facts in his notebook by the light of the fire.
