And it proved to be the case, for, with the surf thundering on either hand, we sailed into a smoothly flowing inlet through which the flood tide was running between high dunes all sparkling in the moonlight and crowned with shadowy palms.

Occasionally I heard noises ahead of us from the other boat, as though Kemper was trying to converse with us, but as his apropos was as unintelligible as it was inopportune, I pretended not to hear him.

Besides, I had all I could do to manoeuvre the tiller and prevent Evelyn Grey from falling off backward into the bayou. Besides, it is not customary to converse with the man at the helm.

After a while--during which I seemed to distinguish in Kemper's voice a quality that rhymes with his name--his tones varied through phases all the way from irony to exasperation. After a while he gave it up and took to singing.

There was a moon, and I suppose he thought he had a voice. It didn't strike me so. After several somewhat melancholy songs, he let off his pistol two or three times and then subsided into silence.

I didn't care; neither his songs nor his shots interrupted--but let that pa.s.s, also.

We were now sailing into the forest through pool after pool of interminable lagoons, startling into unseen and clattering flight hundreds of waterfowl. I could feel the wind from their whistling wings in the darkness, as they drove by us out to sea. It seemed to startle the pretty waitress. It is a solemn thing to be responsible for a pretty girl's peace of mind. I rea.s.sured her continually, perhaps a trifle nervously. But there were no more pistol shots. Perhaps Kemper had used up his cartridges.

We were still drifting along under drooping sails, borne inland almost entirely by the tide, when the first pale, watery, gray light streaked the east. When it grew a little lighter, Evelyn sat up; all danger of sharks being over. Also, I could begin to see what was going on in the other boat. Which was nothing remarkable; Kemper slumped against the mast, his head turned in our direction; Grue sat at the helm, motionless, his tattered straw hat sagging on his neck.

When the sun rose, I called out cheerily to Kemper, asking him how he had pa.s.sed the night. Evelyn also raised her head, pausing while bringing her disordered hair under discipline, to listen to his reply.

But he merely mumbled something. Perhaps he was still sleepy.

As for me, I felt exceedingly well; and when Grue turned his craft in sh.o.r.e, I did so, too; and when, under the overhanging foliage of the forest, the nose of my boat grated on the sand, I rose and crossed the deck with a step distinctly frolicsome.

Kemper seemed distant and glum; Evelyn Grey spoke to him shyly now and then, and I noticed she looked at him only when he was gazing elsewhere than at her. She had a funny, conciliatory air with him, half ashamed, partly humorous and amused, as though something about Kemper's sulky ill-humour was continually making tiny inroads on her gravity.

Some mullet had jumped into the two boats--half a dozen during our moonlight voyage--and these were now being fried with rice for us by Grue. Lord! How I hated to eat them!

After we had finished breakfast, Grue, as usual, did everything to the remainder except to get into the fry-pan with both feet; and as usual he sickened me.

When he'd cleaned up everything, I sent him off into the forest to find a dry sh.e.l.l-mound for camping purposes; then I made fast both boats, and Kemper and I carried ash.o.r.e our paraphernalia, spare _batterie-de-cuisine_, firearms, fishing tackle, spears, harpoons, grains, oars, sails, spars, folding cage--everything with which a strictly scientific expedition is usually burdened.

Evelyn was washing her face in the crystal waters of a branch that flowed into the lagoon from under the live-oaks. She looked very pretty doing it, like a naiad or dryad scrubbing away at her forest toilet.

It was, in fact, such a pretty spectacle that I was going over to sit beside her while she did it, but Kemper started just when I was going to, and I turned away. Some men invariably do the wrong thing. But a handsome man doesn't last long with a pretty girl.

I was thinking of this as I stood contemplating an alligator slide, when Grue came back saying that the sh.o.r.e on which we had landed was the termination of a sh.e.l.l-mound, and that it was the only dry place he had found.

So I bade him pitch our tents a few feet back from the sh.o.r.e; and stood watching him while he did so, one eye reverting occasionally to Evelyn Grey and Kemper. They both were seated cross-legged beside the branch, and they seemed to be talking a great deal and rather earnestly. I couldn't quite understand what they found to talk about so earnestly and volubly all of a sudden, inasmuch as they had heretofore exchanged very few observations during a most brief and formal acquaintance, dating only from sundown the day before.

Grue set up our three tents, carried the luggage inland, and then hung about for a while until the vast shadow of a vulture swept across the trees.

I never saw such an indescribable expression on a human face as I saw on Grue's as he looked up at the huge, unclean bird. His vitreous eyes fairly glittered; the corners of his mouth quivered and grew wet; and to my astonishment he seemed to emit a low, mewing noise.

"What the devil are you doing?" I said impulsively, in my amazement and disgust.

He looked at me, his eyes still glittering, the corners of his mouth still wet; but the curious sounds had ceased.

"What?" he asked.

"Nothing. I thought you spoke." I didn't know what else to say.

He made no reply. Once, when I had partly turned my head, I was aware that he was warily turning his to look at the vulture, which had alighted heavily on the ground near the entrails and heads of the mullet, where he had cast them on the dead leaves.

I walked over to where Evelyn Grey and Kemper sat so busily conversing; and their volubility ceased as they glanced up and saw me approaching.

Which phenomenon both perplexed and displeased me.

I said:

"This is the Black Bayou forest, and we have the most serious business of our lives before us. Suppose you and I start out, Kemper, and see if there are any traces of what we are after in the neighborhood of our camp."

"Do you think it safe to leave Miss Grey alone in camp?" he asked gravely.

I hadn't thought of that:

"No, of course not," I said. "Grue can stay."

"I don't need anybody," she said quickly. "Anyway, I'm rather afraid of Grue."

"Afraid of Grue?" I repeated.

"Not exactly afraid. But he's--unpleasant."

"I'll remain with Miss Grey," said Kemper politely.

"Oh," she exclaimed, "I couldn't ask that. It is true that I feel a little tired and nervous, but I can go with you and Mr. Smith and Grue--"

I surveyed Kemper in cold perplexity. As chief of the expedition, I couldn't very well offer to remain with Evelyn Grey, but I didn't propose that Kemper should, either.

"Take Grue," he suggested, "and look about the woods for a while. Perhaps after dinner Miss Grey may feel sufficiently rested to join us."

"I am sure," she said, "that a few hours' rest in camp will set me on my feet. All I need is rest. I didn't sleep very soundly last night."

I felt myself growing red, and I looked away from them both.

"Oh," said Kemper, in apparent surprise, "I thought you had slept soundly all night long."

"n.o.body," said I, "could have slept very pleasantly during that musical performance of yours."

"Were you singing?" she asked innocently of Kemper.

"He was singing when he wasn't firing off his pistol," I remarked. "No wonder you couldn't sleep with any satisfaction to yourself."

Grue had disappeared into the forest; I stood watching for him to come out again. After a few minutes I heard a furious but distant noise of flapping; the others also heard it; and we listened in silence, wondering what it was.

"It's Grue killing something," faltered Evelyn Grey, turning a trifle pale.

"Confound it!" I exclaimed. "I'm going to stop that right now."

Kemper rose and followed me as I started for the woods; but as we pa.s.sed the beached boats Grue appeared from among the trees.

"Where have you been?" I demanded.
