I knew the symptoms only two well. The entire encampment of Consciousness was feverishly awake, was alert, was on the qui-vive. That pulsing white pin-wheel was purely a personal matter between me and my imagination. It was something distinctly my own. It was Me. And being essentially subjective, it could be neither banished nor controlled.

So I decided to make for the open. To think of a four-poster, in any such era of intensified wakefulness, would be a mockery. For I was the arena of that morbid wakefulness which brought with it an over-crowded mental consciousness of existence far beyond my own physical vision, as though I had been appointed night-watchman for the whole round world, with a searching eye on all its multitudinous activities and aberrations. I seemed able to catch its breathing as it slept its cosmic sleep. I seemed to brood with lunar aloofness above its teeming plains, depressed by its enormous dimensions, confused by its incomprehensible tangle and clutter of criss-cross destinies. Its uncountable midnight voices seemed to merge into a vague sigh, so pensively remote, so inexpressibly tragic, that when I stood in my doorway and caught the sound of a harebrained young Romeo go whistling down past the Players' Club his shrill re-piping of a Broadway roof-song seemed more than discordant; it seemed desecration. The fool was happy, when the whole world was sitting with its fists clenched, awaiting some undefined doom.

It was long past midnight, I remembered as I closed the door. For it must have been, an hour and more since I had looked out and seen the twelve ruby flashes from the topmost peak of the Metropolitan Tower signaling its dolorous message that another day had gone. I had watched those twelve winks with a sinking heart, finding something sardonic in their brisk levity, for I had been reminded by a telltale neurasthenic twitching of my right eyelid that some angling Satan known as Insomnia was once more tugging and jerking at my soul, as a fly-hook tugs and jerks at a trout's mouth.

I knew, even as I wandered drearily off from my house-door and paced as drearily round and round the iron-fence park enclosure, that I was destined for another sleepless night. And I had no intention of passing it cooped up between four walls. I had tried that before, and in that way, I remembered, madness lay.

So I wandered restlessly on through the deserted streets, with no active thought of destination and no immediate sense of direction. All I remembered was that the city lay about me, bathed in a night of exceptional mildness, a night that should have left it beautiful. But it lay about me, in its stillness, as dead and flat and stale as a tumbler of tepid wine.

I flung myself wearily down on a bench in Madison Square, facing the slowly spurting fountain that had so often seemed to me a sort of visible pulse of the sleeping city. I sat peering idly up at the Flatiron Building, where like an eternal plowshare it threw its eternal cross furrows of Fifth Avenue and Broadway along the city's tangled stubble of steel and stone. Then I peered at the sleepers all about me, the happy sleepers huddled and sprawled along the park benches. I envied them, every mortal of that ragged and homeless army! I almost hated them. For they were drinking deep of the one thing I had been denied.

As I lounged there with my hat pulled down over my eyes, I listened to the soothing purr and splash of the ever-pulsing fountain. Then I let my gaze wander disconsolately southward, out past the bronze statue of Seward. I watched the driver of a Twenty-third Street taxicab of the "night-hawk" variety asleep on his seat. He sat there in his faded hat and coat, as motionless as metal, as though he had loomed there through all the ages, like a brazen statue of Slumber under his mellowing patina of time.

Then, as I gazed idly northward, I suddenly forgot the fountain and the night-hawk chauffeur and the sleepers. For out of Fifth Avenue, past where the double row of electric globes swung down the gentle slope of Murray Hill like a double pearl-strand down a woman's breast, I caught sight of a figure turning quietly into the quietness of the square. It attracted and held my eye because it seemed the only movement in that place of utter stillness, where even the verdigris-tinted trees stood as motionless as though they had been cut from plates of copper.

I watched the figure as it drew nearer and nearer. The lonely midnight seemed to convert the casual stroller into an emissary of mystery, into something compelling and momentous. I sat indolently back on my park bench, peering at him as he drifted in under the milk-white arc lamps whose scattered globes were so like a scurry of bubbles caught in the tree branches.

I watched the stranger as closely as a traveler in mid-ocean watches the approach of a lonely steamer. I did not move as he stood for a moment beside the fountain. I gave no sign of life as he looked slowly about, hesitated, and then crossed over to the end of the very bench on which I sat. There was something military-like about the slim young figure in its untimely and incongruous cape overcoat. There was also something alert and guardedly observant in the man's movements as he settled himself back in the bench. He sat there listening to the purr and splash of the water. Then, in an incredibly short space of time, he was fast asleep.
