of shallow, sparkling water, or, when the wind veered, whirled back into our faces across the reef, curling and eddying among the standing mangroves like fog drifting.
Seated there near the fire, from time to time I swept the horizon with my marine glasses; but there was no sign of Kemper; no sail broke the far sweep of sky and water; nothing moved out there save when a wild duck took wing amid the dark raft of its companions to circle low above the ocean and settle at random, invisible again except when, at intervals, its white breast flashed in the sunshine.
Meanwhile the waitress had ceased to write in her diary and now sat with the closed book on her knees and her pencil resting against her lips, gazing thoughtfuly at the back of Grue's head.
It was a ratty head of straight black hair, and looked greasy. The rest of him struck me as equally unkempt and dingy—a youngish man, lean, deeply bitten by the sun of the semi-tropics to a mahogany hue, and unusually hairy.
I don't mind a brawny, hairy man, but the hair on Grue's arms and chest was a rusty red, and like a chimpanzee's in texture, and sometimes a wildly absurd idea possessed me that the man needed it when he went about in the palm forests without his clothes.
But he was only a "poor white"—a "cracker" recruited from one of the reefs near Pelican Light, where he lived alone by fishing and selling his fish to the hotels at Heliatrope City. The sail-boat was his; he figured as our official guide on this expedition—an expedition which already had begun to worry me a great deal.
For it was, perhaps, the wildest goose chase and the most absurdly hopeless enterprise ever undertaken in the interest of science by the Bronx Park authorities.
Nothing is more dreaded by scientists than ridicule; and it was in spite of this terror of ridicule that I summoned sufficient courage to organize an exploring party and start out in search of something so extraordinary, so hitherto unheard of, that I had not dared reveal to Kemper by letter the object of my quest.
No, I did not care to commit myself to writing just yet; I had merely sent Kemper a letter to join me on Sting-ray Key.
He telegraphed me from Tampa that he would join me at the rendezvous; and I started directly from Bronx Park for Heliatrope City; arrived there in three days; found the waitress all ready to start with me; inquired about a guide and discovered the man Grue in his hut off Pelican Light; made my bargain with him; and set sail for Sting-ray Key, the most excited and the most nervous young man who ever had dared disaster in the sacred cause of science.
Everything was now at stake, my honour, reputation, career, fortune. For, as chief of the Anthropological Field Survey Department of the great Bronx Park Zoölogical Society, I was perfectly aware that no scientific reputation can survive ridicule.
Nevertheless, the die had been cast, the Rubicon crossed in a sail-boat containing one beachcombing cracker, one hotel waitress, a pile of camping kit and special utensils, and myself!
How was I going to tell Kemper? How was I going to confess to him that I was staking my reputation as an anthropologist upon a letter or two and a personal interview with a young girl—a waitress at the Hotel Gardenia in Heliatrope City?
I lowered my sea-glasses and glanced sideways at the waitress. She was still chewing the end of her pencil, reflectively.
She was a pretty girl, one Evelyn Grey, and had been a country school-teacher in Massachusetts until her health broke.
Florida was what she required; but that healing climate was possible to her only if she could find there a self-supporting position.
Also she had nourished an ambition for a postgraduate education, with further aspirations to a Government appointment in the Smithsonian Institute.
All very worthy, no doubt—in fact, particularly commendable because the wages she saved as waitress in a Florida hotel during the winter were her only means of support while studying for college examinations during the summer in Boston, where she lived.
Yet, although she was an inmate of Massachusetts, her face and figure would have ornamented any light-opera stage. I never looked at her but I thought so; and her cuffs and apron merely accentuated the delusion. Such ankles are seldom seen when the curtain rises after the overture. Odd that frivolous thoughts could flit through an intellect dedicated only to science!
The man, Grue, had not stirred from his survey of the Atlantic Ocean. He had a somewhat disturbing capacity for remaining motionless—like a stealthy and predatory bird which depends on immobility for aggressive and defensive existence.
The sea-wind fluttered his cotton shirt and trousers and the tattered brim of his straw hat. And always I felt as though he were watching me out of the back of his ratty head, through the ravelled straw brim that sagged over his neck.
The pretty waitress had now chewed the end of her pencil to a satisfactory pulp, and she was writing again in her diary, very intently, so that my cautious touch on her arm seemed to startle her.
Meeting her inquiring eyes I said in a low voice:
"I am not sure why, but I don't seem to care very much for that man, Grue. Do you?"
She glanced at the water's edge, where Grue stood, immovable, his back still turned to us.
"I never liked him," she said under her breath.
"Why?" I asked cautiously.
She merely shrugged her shoulders. She did it gracefully.
I said:
"Have you any particular reason for disliking him?"
"He's dirty."
"He looks dirty, yet every day he goes into the sea and swims about. He ought to be clean enough."
She thought for a moment, then:
"He seems, somehow, to be fundamentally unclean—I don't mean that he doesn't wash himself. But there are certain sorts of animals and birds and other creatures from which one instinctively shrinks—not, perhaps, because they are materially unclean—"
"I understand," I said. After a silence I added: "Well, there's no chance now of sending him back, even if I were inclined to do so. He appears to be familiar with these latitudes. I don't suppose we could find a better man for our purpose. Do you?"
"No. He was a sponge fisher once, I believe."
"Did he tell you so?"
"No. But yesterday, when you took the boat and cruised to the south, I sat writing here and keeping up the fire. And I saw Grue climbing about among the mangroves over the water in a most uncanny way; and two snake-birds sat watching him, and they never moved.
"He didn't seem to see them; his back was toward them. And then, all at once, he leaped backward at them where they sat on a mangrove, and he got one of them by the neck—"
"Climbing about among the mangroves above the water"
"What!"
The girl nodded.
"By the neck," she repeated, "and down they went into the water. And what do you suppose happened?"
"I can't imagine," said I with a grimace.
"Well, Grue went under, still clutching the squirming, flapping bird; and he stayed under."
"Stayed under the water?"
"Yes, longer than any sponge diver I ever heard of. And I was becoming frightened when the bloody bubbles and feathers began to come up—"
"What was he doing under water?"
"He must have been tearing the bird
