"Well, he seems just as wild about them as ever, and so I reckon he'll just keep on bothering us to the end of the chapter. But what are you looking at, Andy?" and Frank also turned his eyes down toward the fringe of quince trees that marked the old lane leading to the barnyard from the road.
"I thought I saw some one coming over there, and if it turned out to be our good friend, the profess, p'raps we'd be wise to skip out before he sighted us, Frank."
"Here, let's step back out of sight, anyhow, so as to be ready to slip away if it is our man," and Frank drew his companion around the corner of the house, from which point they could still keep watch over the lane.
Half a minute later Andy whispered:
"There, I saw him again, Frank, and as sure as anything it must be Casper. He's a little man, wearing brown glasses to keep the bright sun from his eyes, and yes, he's carrying a butterfly catcher's net over his shoulder. Shall we disappear?"
"I think that would be our best move, Andy; and lucky enough we've got the chance to slip around here, and get back of the barn before he comes along," with which the two boys hastened to follow out the plan suggested.
