Armitage gazed after her, as if petrified. His first impulse was to cry out, to run after her, to attract her attention. He stumbled forward and then stopped. What right had he to accost her? She might resent it as an unwarrantable impertinence. It would humiliate and embarrass her to be addressed amid that fashionable throng by a common workman. It was enough that he had seen her—from a distance. That was all the happiness he could reasonably expect. By the time he had reasoned with himself, Grace was out of sight.

That evening when Armitage reached his lodgings he found awaiting him a letter bearing the Boston postmark. Opening it, he saw it contained another letter addressed to him and forwarded in care of the Boston office of the owners of the Saucy Polly. Tearing open the envelope, he read as follows:

"— Fifth Avenue.

"Dear Mr. Armitage: If you happen to be in New York, I should be glad if you could find it convenient to call at the above address.

"Yours faithfully,
"John Harmon."


CHAPTER XVIII.

The town house of John Harmon was conspicuous for its size and beauty even on an avenue famous for its magnificent residences. With a frontage of a hundred feet facing Central Park, it was constructed entirely of French gray stone, Renaissance style, with turrets, gables, oriel windows, elaborately carved stone loggias and balconies, tiled roofs and all the other architectural ornamentation of that picturesque period. Set back some distance from the road, it was surrounded by tastefully laid-out grounds, with a handsome portico decorated by elaborate stone carvings, and a driveway bordered with flower-beds, entrance to which was made through ornamental gates of massive bronze.

Beautiful from the exterior as was this railroad king's home, within it was furnished with the lavish grandeur of a royal palace. All Europe had been ransacked to fill it with beautiful and costly art treasures. At the back of the large entrance-hall, with its magnificent frescoed ceilings, its satin hangings, marble pillars and stained-glass windows, was a monumental staircase of pure Italian marble and graceful design which led to the reception-room and other apartments above. The stairway was artistically decorated with marble statuary, trophies of arms and priceless tapestries. On the second floor were the famous art-galleries hung with paintings by the ancient and modern masters.

It was only on extraordinary occasions that visitors were afforded an opportunity to see all the art treasures which the house contained. For the greater part of the year the pictures were not on view. To-day, however, was one of the rare exceptions. Mr. Harmon had thrown open his entire house in honor of the special event which he was celebrating.
