The taxicab turned swiftly into Twenty-third Street, and while it stopped beside the pavement, she saw that Mrs. Squires was standing, with her arms on the gate, staring into the street.  As Gabriella alighted, the woman came forward and said, with suppressed emotion, while she wiped her eyes on the back of her hand:  “You came just a minute too late to say good-bye to Mr. O’Hara.”

“Good-bye?  But where has he gone?”

“He has gone to Washington to-night.  To-morrow he is starting to the West.”

“When is he coming back?  Did he tell you?”

At this Mrs. Squires broke down.  “He ain’t ever coming back, that’s what I’m crying for.  He’s given up his rooms, and his furniture all went to the auction yesterday.  He says he’s going to live out in Colorado or Wyoming for the rest of his life, and he didn’t even tell me where I could write to him.  It’s a great loss to me, Mrs. Carr.  I’d got used to him and his ways, and when you’ve once got used to a man, it ain’t easy to give him up.”

She sobbed audibly as she finished; and it seemed to Gabriella that a lifetime of experience passed in the instant while she stood there, with her pulses drumming in her ears, her throat contracting until she struggled for breath, and the lights of the city swimming in a nebulous blur before her eyes.  Yet in that instant, as in every crisis of her life, she turned instinctively to action, to movement, to exertion, however futile.  While she walked across the pavement to the waiting cab, for the crowning and ultimate choice of her life, she abandoned forever the authority and guide of tradition.  Tradition, she knew, bade her sit and wait on destiny until she withered, like Arthur, to the vital core of her nature; but something mightier than tradition, something which she shared with the swarming multitude of children in the streets—­the will to live, to strive, and to conquer—­this had risen superior to the empty rules of the past.  With her hand on the door of the taxicab, she spoke rapidly to the driver:  “Drive back to the station as fast as you can, there is not a minute to lose.”

When the cab started, she leaned forward, with her hands clasped on her knees, and her eyes on the street, where the children were playing.  Because of the children, they drove very slowly, and once, when the traffic held them up for a few minutes, she felt an impulse to scream.  Suppose she missed him, after all!  Suppose she lost him in the station!  Suppose she never saw him again!  And beside this possibly it seemed to her that all the other suffering of her life—­George’s desertion, her humiliation, her struggle to make a living for her children, the loneliness of the long summers, her poverty and hunger and self-denial—­that all these things were merely superficial annoyances.  “If we don’t go on, I shall die,” she said aloud suddenly; “if we don’t go on, I shall die,” and when at last the cab started again, she heard the words like an undercurrent beneath the innumerable noises of the street, “If we don’t go on, I shall die.”
