Harvey's big sitting room was popular. His friends had the comfortable habit of dropping in at almost any hour of the day or night, sure of a hearty welcome. But to-night the thought of visitors caused him to replace the picture suddenly, seize his hat and stick, and start out for—somewhere. At first he entertained a dim notion of going to Lincoln Park, so he took the elevated down town, and started north on the Clark Street cable. But as the car jolted along, he remembered that the band did not play Tuesday evenings. He might take in the electric fountain, but in the crowd you couldn't go about and look at people without being in other people's way. Harvey was fond of the great public, but he liked to hold himself in the background. He rode past the Park under the long row of elms, gazing absently at the thronging walk where the middle strata of North Side humanity take their evening promenade. Passing the Park, he decided to go on to the Bismarck, where he could be among people and yet remain alone.

A few minutes before eight he walked between the brown dragons which guard the entrance, and crossed the raised pavilion between the street and the garden. At the head of the stairs he paused a moment, then he turned aside and seated himself at a table near by, where he could lean against the railing and overlook the crowd below.

It was still somewhat early, and the long rows of white tables stood vacant. By daylight the trees in a summer garden wear a homesick look, but to-night the festooned incandescent lamps spread a soft yellow light through the foliage, already thinned, though the night was warm, by the touch of September; while high up on their white poles the big arcs threw down a weird blue glare, casting a confusion of half-opaque shadows upon the gravelled earth. Far to the front was the stage with its half dome; the double-bass was tuning his instrument, a few others were sorting music or running over difficult passages.

By this time the crowd was pouring in and spreading among the tables. Harvey leaned back and watched the almost unbroken line that moved from the gate to the steps. There were a great many family groups, with here and there a chaperoned party from the suburbs. A sound of scraping and squealing and grunting from the stage announced the orchestral preliminaries. There was a scattering fusillade of applause as the tall conductor appeared. Looking through the trees, Harvey could see him rap his stand and raise both arms. The concert was on. Harvey's glance shifted back to the stairway, and he started. On the bottom step, looking about for a vacant table, was William C. Porter. Behind him, standing, with head thrown back, was Miss Katherine Porter. For a moment she looked at the shifting scene before her. Harvey noted with hungry eyes the poise of her figure. Then she turned deliberately, and bowed to Harvey with a bright smile.

A little later, as Harvey sat alone listening to the music, Mr. Porter appeared, picking his way toward the centre aisle. Harvey watched him idly. He finally reached the stairway, and came straight to Harvey's table.

“Good evening, Mr. West,” he said, holding out his hand. “Won't you join us? We shall be here for an hour, anyway.”

Harvey rose, and looked across the diagonal line of tables. Miss Porter was leaning forward with a smile. Harvey's mind had been made up, but he changed it and followed Mr. Porter.

Katherine received him brightly and immediately put him at ease. For the time he forgot that Mr. Porter and he were nominal enemies. Mr. Porter talked entertainingly of the people about them, a subject which Harvey could continue with intelligence; and he was gratified to note the interest in the daughter's eyes as he commented on the oddities of human character.

They were looking at a party of Germans, who sat listening to the music with the stolid interest of the race, when Mr. Porter rose and beckoned. Katherine nodded to some one behind Harvey. A moment later he was shaking hands with Mr. McNally.

“We've been watching for you for some time,” said Mr. Porter, as McNally took the vacant chair.
