"Three o'clock, and twenty minutes after!"

Frank found it difficult to believe his eyes. Only an hour and twenty minutes had passed since he started away from home on his wheel to deliver that urgent message for his father; and all these exciting events had happened.

"Better go and see where Helen is," his father had suggested, when they found that Mrs. Allen was lying down with a headache, and the gentleman decided it would be unwise to excite her with the story just then.

That caused Frank to remember that his sister had stated her intention of going for a row upon the river about the time he started off, and that her particular chum, whom Frank himself thought the sweetest girl in all Columbia, was expected to accompany her.

It was only with the desire to be with the girls, and not that he feared any peril could have overtaken them, that Frank immediately started out.

"Let me see, I rather think Paul would like to go along," he mused, with what might be termed a knowing smile; for in thinking of his chum's pleasure Frank perhaps had an ax to grind himself—two boats, two girls, and a fellow in each to do the rowing!

"Is Paul home?" he asked, as he stood outside the door of the "Bird-cage," as his friend's sisters denominated their house.

"Why, yes, I believe he is, Frank. I heard him talking over the 'phone a minute ago; and here he comes tumbling down the stairs right now," replied Amelia, the oldest of the Bird girls.

Paul gave a whoop at sight of the boy on the stoop.

"Was just going to dash over to your house and demand an explanation. What's all this Molly Manners was telling me over the wire just now? Been doing it some more, have you? Fortune knocks at your door right frequently, pard, it seems. Come in and tell us how you captured those two hobo robbers, with the moral backing of Molly, and a few other paper chase runners!"
