I was following an old disused wood-road once when I frightened a robin from her nest. Her mate joined her, and together they raised a great hubbub. Immediately a chewink, a pair of vireos, and two black and white warblers joined the robins in their din. Then a chickadee appeared. He had a worm in his beak. His anxiety seemed so real that I began to watch him, when, looking down among the stones for a place to step, what should I see but his mate emerging from the end of a tiny birch stump at my very feet! She had heard the racket and had come out to see what it was all about. At sight of her, Mr. Chickadee hastened with his worm, brushing my face, almost, as he darted to her side. She took the worm sweetly, for she knew he had intended it for her. But how do I know it was intended for her, and not for the young? There were no young in the nest; only eggs. Even after the young came (there were eight of them!), when life, from daylight to dark, was one ceaseless, hurried hunt for worms, I saw him over and over again fly to Mrs. Chickadee’s side caressingly and tempt her to eat. The house of this pair did not fall. How could it when it stood precisely two and a half feet from the ground? But that it wasn’t looted is due to the amazing boldness of its situation. It stood alone, close to the road, so close that the hub of a low wheel in passing might have knocked it down. Perhaps a hundred persons had brushed it in going by. How many dogs and cats had overlooked it no one can say; nor how many skunks and snakes and squirrels. The accident that discovered it to me had happened apparently to no one else, so here it stood still safe, but only by the grace of Luck! Cutting a tiny window in the bark just above the eggs, I looked in upon the little children every day. I watched them hatch, grow, and fill the cavity and hang over at the top. I was there the day they forced my window open; I was there the day when there was no more room at the top, and when, at the call of their parents, one child after another of this large, sweet bird family found his wings and flew away through the friendly woods. CHAPTER VII A CHAPTER OF THINGS TO DO THIS WINTER I You should go skating--crawling, I ought to say--over a pond of glare ice this winter. Take the pond you are most familiar with. Go early on a bright day, before any skater arrives, and lying flat upon the clear, “black” ice, study the bottom of the pond and the fish that swim below you. They have boats with glass bottoms along the California coast, through which to watch the marvelous bottoms off shore. But an Eastern pond covered with glare ice is as good, for such ice is a plate-glass window into a wonder world. II
