With physical inactivity, consciousness of his surroundings forced themselves on his attention. Subdued, pulsating, penetrating, the murmur of the great hotel came to his ears; the drone of indistinguishable voices, the pattering footsteps of bell-boys and habitués, the purr of the elevator as it moved from floor to floor, the click of the gate as it stopped at his own level, the renewed monotone as it passed by.

Continuous, untiring, the sounds suggested the unthinking vitality of a steam-engine or of a dynamo in a powerhouse. A mechanic by nature, as a school-boy Ben had often induced Scotty to take him to the electric light station, where he had watched the great machines with a fascination bordering on awe, until fairly dragged away by the prosaic Englishman. This feeling of his childhood recurred to him now with irresistible force. The throb of the motor of human life was pulsating in his ears; but added to it was something more, something elusive, intangible, but all-powerful. The moment he had arrived within the city limits he had felt the first trace of its presence. As he approached the centre of congestion it had deepened, had become more and more a guiding influence. Since then, by day or by night, wherever he went, augmenting or diminishing, it was constantly with him. And it was not with him alone. Every human being with whom he came in contact was likewise consciously or unconsciously under the spell. The crowds he had passed on the streets were unthinkingly answering its guidance. The trolley cars echoed its voice. It was the spirit of unrest—a thing ubiquitous and all-penetrating as the air that filled their lungs—a subtle stimulant that they took in with every breath.

Ben Blair arose and put on his hat. He had been sitting only a few minutes, but he felt that he could not longer bear the inactivity. To do so meant to think; and thought was the thing that to-night he was attempting to avoid. Moreover, for one of the few times in his life he could remember he was desperately lonely. It seemed to him that nowhere within a thousand miles was another of his own kind. Instinctively he craved relief, and that alleviation could come in but one way,—through physical activity. Again he sought the street.

To some persons a great relief from loneliness is found in mingling with a crowd, even though it be of strangers; but Ben was not like these. His desire was to be away as far as possible from the maddening drone. Boarding a street car, he rode out into the residence section, clear to the end of the loop; then, alighting, he started to walk back. A full moon had arisen, and outside the shadow-blots of trees and buildings the earth was all alight. The asphalt of the pavements and the cement of the walks glistened white under its rays. Loth to sacrifice the comparative out-of-door coolness for the heat within, practically every house had its group on the doorsteps, or scattered upon the narrow lawns. Accustomed to magnificent distances, to boundless miles of surrounding country, to privacy absolute, Ben watched this scene with a return of the old wonder,—the old feeling of isolation, of separateness. Side by side, young men and women, obviously lovers, kept their places, indifferent to his observation. Other couples, still more careless, sat with circling arms and faces close together, returning his gaze impassively. Nothing, apparently, in the complex gamut of human nature was sacred to these folk. To the solitary spectator, the revelation was more depressing than even the down-town unrest; and he hurried on.

Further ahead he came to the homes of the wealthy,—great piles of stone and brick, that seemed more like hotels than residences. The forbidding darkness of many of the houses testified that their owners were out of town, at the seaside or among the mountains; but others were brilliantly lighted from basement to roof. Before one a long line of carriages was drawn up. Stiffly liveried footmen, impassive as automatons, waited the erratic pleasure of their masters. A little group of spectators was already gathered, and Ben likewise paused, observing the spectacle curiously.

A social event of some sort was in progress. From some concealed place came the music of a string orchestra. Every window of the great pile was open for ventilation, and Ben could hear and see almost as plainly as the guests themselves. For a time, deep, insistent, throbbing in measured beat, came the drone of the 'cello, the wail of the clarionet, and, faintly audible beneath, the rustle of moving feet. Then the music ceased; and a few seconds later a throng of heated dancers swarmed through the open doorway to the surrounding veranda, and simultaneously a chatter broke forth. Fans, like gigantic butterfly wings, vibrated to and fro. Skilful waiters, in black and white, glanced in and out. Laughter, thoughtless and care-free, mingled in the general scene.

The music still, Ben Blair was about to move on, when suddenly a man and a girl in the shadow of a window on the second floor caught and held his attention. As far as he could see, they were alone. Evidently one or the other of them knew the house intimately, and had deliberately sought the place. From the veranda beneath, the flow of talk continued uninterruptedly; but they gave it no attention. The spectator could distinctly see the man as he leaned back in the light and spoke earnestly. At times he gesticulated with rapid passionate motions, such as one unconsciously uses when deeply absorbed. Now and again, with the bodily motions that we have learned to connect with the French, his shoulders were shrugged expressively. He was obviously talking against time; for his every motion showed intense concentration. No spectator could have mistaken the nature of his speech. Passion supreme, abandon absolute, were here personified. As he spoke, he gradually leaned farther forward toward the woman who listened. His face was no longer in the light. Suddenly, at first low, as though coming from a distance, increasing gradually until it throbbed into the steady beat of a waltz, the music recommenced. It was the signal for action and for throwing off restraint. The man leaned forward; his arm stretched out and closed about the figure of the woman. His face pressed forward to meet hers, again and again.

Not Ben alone, but a half-dozen other spectators had watched the scene. An overdressed girl among the number tittered at the sight.

But Ben scarcely noticed. With the strength of insulted womanhood, the girl had broken free, and now stood up full in the light. One look she gave to the man, a look which should have withered him with its scorn; then, gathering her skirts, she almost ran from the room.

Only a few seconds had the girl's face been clear of the shadow; yet it had been long enough to permit recognition, and instantly liquid fire flowed in the veins of Benjamin Blair. His breath came quick and short as that of a runner passing under the wire, and his great jaw set. The woman he had seen was Florence Baker.
