Days passed, and the usurpers prospered and the outcasts were wretched; but the latter lingered about, watching and abusing their enemies, and hoping, no doubt, that things would take a turn, as they presently did. The outraged wrens were fully avenged. The mother bluebird had laid her full complement of eggs and was beginning to set, when one day, as her mate was perched above her on the barn, along came a boy with one of those wicked elastic slings and cut him down with a pebble. There he lay like a bit of sky fallen upon the grass. The widowed bird seemed to understand what had happened, and without much ado disappeared next day in quest of another mate. How she contrived to make her wants known, without trumpeting them about, I am unable to say. But I presume that birds have a way of advertising that answers the purpose well. Maybe she trusted to luck to fall in with some stray bachelor or bereaved male who would undertake to console a widow or one day's standing. I will say, in passing, that there are no bachelors from choice among the birds; they are all rejected suitors, while old maids are entirely unknown. There is a Jack to every Jill; and some to boot. The males, being more exposed by their song and plumage, and by being the pioneers in migrating, seem to be slightly in excess lest the supply fall short, and hence it sometimes happens that a few are bachelors perforce; there are not females enough to go around, but before the season is over there are sure to be some vacancies in the marital ranks, which they are called on to fill. In the mean time the wrens were beside themselves with delight; they fairly screamed with joy. If the male was before "ruffled with whirlwind of his ecstasies," he was now in danger of being rent asunder. He inflated his throat and caroled as wren never caroled before. And the female, too, how she cackled and darted about! How busy they both were! Rushing into the nest, they hustled those eggs out in less than a minute, wren time. They carried in new material, and by the third day were fairly installed again in their old headquarters; but on the third day, so rapidly are these little dramas played, the female bluebird reappeared with another mate. Ah! how the wren stock went down then! What dismay and despair filled again those little breasts! It was pitiful. They did not scold as before, but after a day or two withdrew from the garden, dumb with grief, and gave up the struggle.
