"I saw it do that!" I burst out.

"Oh, did you? Well, _what was it?_"

Something kept me silent, although a dozen explanations flew to my lips.

After a pause, Halyard said: "You saw the harbor-master, that's what you saw!"

I looked at him without a word.

"Don't mistake me," he said, pettishly; "I don't think that the harbor-master is a spirit or a sprite or a hobgoblin, or any sort of d.a.m.ned rot. Neither do I believe it to be an optical illusion."

"What do you think it is?" I asked.

"I think it's a man--I think it's a branch of the human race--that's what I think. Let me tell you something: the deepest spot in the Atlantic Ocean is a trifle over five miles deep--and I suppose you know that this place lies only about a quarter of a mile off this headland. The British exploring vessel, _Gull_, Captain Marotte, discovered and sounded it, I believe. Anyway, it's there, and it's my belief that the profound depths are inhabited by the remnants of the last race of amphibious human beings!"

This was childish; I did not bother to reply.

"Believe it or not, as you will," he said, angrily; "one thing I know, and that is this: the harbor-master has taken to hanging around my cove, and he is attracted by my nurse! I won't have it! I'll blow his fishy gills out of his head if I ever get a shot at him! I don't care whether it's homicide or not--anyway, it's a new kind of murder and it attracts me!"

I gazed at him incredulously, but he was working himself into a pa.s.sion, and I did not choose to say what I thought.

"Yes, this slate-colored thing with gills goes purring and grinning and spitting about after my nurse--when she walks, when she rows, when she sits on the beach! Gad! It drives me nearly frantic. I won't tolerate it, I tell you!"

"No," said I, "I wouldn't either." And I rolled over in bed convulsed with laughter.

The next moment I heard my door slam. I smothered my mirth and rose to close the window, for the land-wind blew cold from the forest, and a drizzle was sweeping the carpet as far as my bed.

That luminous glare which sometimes lingers after the stars go out, threw a trembling, nebulous radiance over sand and cove. I heard the seething currents under the breakers' softened thunder--louder than I ever heard it. Then, as I closed my window, lingering for a last look at the crawling tide, I saw a man standing, ankle-deep, in the surf, all alone there in the night. But--was it a man? For the figure suddenly began running over the beach on all fours like a beetle, waving its limbs like feelers. Before I could throw open the window again it darted into the surf, and, when I leaned out into the chilling drizzle, I saw nothing save the flat ebb crawling on the coast--I heard nothing save the purring of bubbles on seething sands.

It took me a week to perfect my arrangements for transporting the great auks, by water, to Port-of-Waves, where a lumber schooner was to be sent from Pet.i.te Sainte Isole, chartered by me for a voyage to New York.

I had constructed a cage made of osiers, in which my auks were to squat until they arrived at Bronx Park. My telegrams to Professor Farrago were brief. One merely said "Victory!" Another explained that I wanted no a.s.sistance; and a third read: "Schooner chartered. Arrive New York July 1st. Send furniture-van to foot of Bluff Street."

My week as a guest of Mr. Halyard proved interesting. I wrangled with that invalid to his heart's content, I worked all day on my osier cage, I hunted the thimble in the moonlight with the pretty nurse. We sometimes found it.

As for the thing they called the harbor-master, I saw it a dozen times, but always either at night or so far away and so close to the sea that of course no trace of it remained when I reached the spot, rifle in hand.

I had quite made up my mind that the so-called harbor-master was a demented darky--wandered from, Heaven knows where--perhaps shipwrecked and gone mad from his sufferings. Still, it was far from pleasant to know that the creature was strongly attracted by the pretty nurse.

She, however, persisted in regarding the harbor-master as a sea-creature; she earnestly affirmed that it had gills, like a fish's gills, that it had a soft, fleshy hole for a mouth, and its eyes were luminous and lidless and fixed.

"Besides," she said, with a shudder, "it's all slate color, like a porpoise, and it looks as wet as a sheet of india-rubber in a dissecting-room."

The day before I was to set sail with my auks in a cat-boat bound for Port-of-Waves, Halyard trundled up to me in his chair and announced his intention of going with me.

"Going where?" I asked.

"To Port-of-Waves and then to New York," he replied, tranquilly.

I was doubtful, and my lack of cordiality hurt his feelings.

"Oh, of course, if you need the sea-voyage--" I began.

"I don't; I need you," he said, savagely; "I need the stimulus of our daily quarrel. I never disagreed so pleasantly with anybody in my life; it agrees with me; I am a hundred per cent. better than I was last week."

I was inclined to resent this, but something in the deep-lined face of the invalid softened me. Besides, I had taken a hearty liking to the old pig.

"I don't want any mawkish sentiment about it," he said, observing me closely; "I won't permit anybody to feel sorry for me--do you understand?"

"I'll trouble you to use a different tone in addressing me," I replied, hotly; "I'll feel sorry for you if I choose to!" And our usual quarrel proceeded, to his deep satisfaction.

By six o'clock next evening I had Halyard's luggage stowed away in the cat-boat, and the pretty nurse's effects corded down, with the newly hatched auk-chicks in a hat-box on top. She and I placed the osier cage aboard, securing it firmly, and then, throwing tablecloths over the auks' heads, we led those simple and dignified birds down the path and across the plank at the little wooden pier. Together we locked up the house, while Halyard stormed at us both and wheeled himself furiously up and down the beach below. At the last moment she forgot her thimble. But we found it, I forget where.

"Come on!" shouted Halyard, waving his shawls furiously; "what the devil are you about up there?"

He received our explanation with a sniff, and we trundled him aboard without further ceremony.

"Don't run me across the plank like a steamer trunk!" he shouted, as I shot him dexterously into the c.o.c.k-pit. But the wind was dying away, and I had no time to dispute with him then.

The sun was setting above the pine-clad ridge as our sail flapped and partly filled, and I cast off, and began a long tack, east by south, to avoid the spouting rocks on our starboard bow.

The sea-birds rose in clouds as we swung across the shoal, the black surf-ducks scuttered out to sea, the gulls tossed their sun-tipped wings in the ocean, riding the rollers like bits of froth.

Already we were sailing slowly out across that great hole in the ocean, five miles deep, the most profound sounding ever taken in the Atlantic. The presence of great heights or great depths, seen or unseen, always impresses the human mind--perhaps oppresses it. We were very silent; the sunlight stain on cliff and beach deepened to crimson, then faded into sombre purple bloom that lingered long after the rose-tint died out in the zenith.

Our progress was slow; at times, although the sail filled with the rising land breeze, we scarcely seemed to move at all.

"Of course," said the pretty nurse, "we couldn't be aground in the deepest hole in the Atlantic."

"Scarcely," said Halyard, sarcastically, "unless we're grounded on a whale."

"What's that soft thumping?" I asked. "Have we run afoul of a barrel or log?"

It was almost too dark to see, but I leaned over the rail and swept the water with my hand.

Instantly something smooth glided under it, like the back of a great fish, and I jerked my hand back to the tiller. At the same moment the whole surface of the water seemed to begin to purr, with a sound like the breaking of froth in a champagne-gla.s.s.

"What's the matter with you?" asked Halyard, sharply.

"A fish came up under my hand," I said; "a porpoise or something--"

With a low cry, the pretty nurse clasped my arm in both her hands.
