Betsy Butterfly in "Johnnie Green's Net"

Johnnie Green was never quite happy unless he was collecting something. One year he went about with a hammer, chipping a piece off almost every rock in Pleasant Valley. And of course he gathered birds' eggs.After he tired of that he began collecting postage stamps. Next he turned his attention to tobacco tags, even hailing travellers who passed the house, to ask them whether they hadn't a "hard one," meaning by that a tag that was hard to get.
