From this day the twins no longer stayed in the nest, but took their position across the top, resting on the edges. By the sixteenth day tails had attained respectable dimensions, and they were clad in the complete dress of feathers, though, having not as yet learned to manage their garments, individual feathers stood out all over and were blown by every breeze into tiny green ripples. In their new position across the top they of course entirely covered the edge, so that the mother was puzzled to find a place for her feet when she came to feed, until she took to alighting on the backs of her monopolizing offspring. All through these delightful days I had kept a sharp lookout for the father of this charming family, for, as is well known, there is a charge against the ruby-throat, that he takes no part in the home life, that he never visits the nest. Whether it be that he is too gay a rover to attend to his duties, whether--as is said of the turkey and some other birds--he is possessed of a rage for destroying his own young, whether he keeps out of sight as a measure of prudence for the safety of the nest, or whether that fearless and industrious little mate of his feels capable of managing her own affairs and so drives him away, no one has as yet been rash enough to say. That remains for future observers to find out. The points most interesting to discover at present are, if it is a fact that he never shows himself; if he remains in the neighborhood, and joins his family later, as has been asserted; or if he resumes his care-free bachelor life, and sees them no more. Only three times was my close watch for visiting hummingbirds rewarded, and those were not at all conclusive. One morning, attracted by the shimmering floor of jewel which Lake Champlain presented under the morning sun, I sat looking out over my neighbor's cornfield, where goldfinch babies were filling the air with their quaint little two-note cries, absorbed in the lovely view, when suddenly I heard a whir of wings and looked up to see a hummer flying about near the nest where madam was sitting. It made two or three jerks, approaching within six inches, and then darted away. Instantly she followed, but not as if in pursuit. There were no cries. It seemed to me a friendly move, an invitation and a response. Alert as she was, she must have seen the stranger, as he--or she--hovered about, yet she did not resent it. In a few minutes she returned and settled herself on her nest. [Sidenote: _GREETING ME WITH CRIES._]
