Out of the bushes came a form he recognized.

It was a rather compact figure upon which he gazed, and the clothes greatly resembled Brother-in-law Andrew's Sunday-best.

Yes, Hugh no longer had any doubts, for the man was no other than the reformed hobo.
"I've known that Brother Lu had taken to tramping about the country latterly," he muttered to himself, as he watched the other going off, apparently laughing as though greatly amused, "for a number of people have told me as much.

That's all right, but why should he want to hide from me?
I've got a good notion to chase after him, once he turns that other bend, and see what it all means." The idea must have appealed more and more strongly to Hugh then, for two minutes afterwards, when the form of the tramp could no longer be seen ahead, he went back to his wheel, mounted, and retraced his course until he arrived at the second abrupt curve.
Again he dismounted and crept forward to see what he might discover.
Strange to say, Hugh, usually steady-going Hugh, now found himself trembling all over, just as though he anticipated making a startling discovery.
Well, he did.
Brother Lu was in plain sight.

He was just approaching the stalled car that stood at the side of the road.
