Purple grackles creaked and clattered in the trees, and the bushes were full of song-sparrow notes, as the Band hurried away from the house-line toward the Land of the Wild-Folk, where Romance still dwells and adventures lurk behind every bush. A tottering stone chimney marked its boundaries. There old Roberts Road began. On and beyond Roberts Road anything might happen. Each one of the Band, in addition to the lethal weapons already set forth, carried a note-book and a pencil with which to keep a list of all birds seen and heard, with notes on the same. Even Corporal Alice-Palace, who was only six, carried a blank-book about the size of a geography. To date it contained this single entry: "Robbins eat wormes. I saw him do it." The Quartermaster-General, despite the difficulty of the evening before, had seen to it that the Band carried with them the very finest lunch that any treasure-hunters ever had since Pizarro dined with the Inca of Peru. As they moved deep and deeper into Wild-Folk Land the air was full of bird-songs. The Captain made them stop and listen to the singing sparrows. First there was the song sparrow, who begins with three notes and wheezes a little as he sings. It took them longer to learn the quieter song of the vesper sparrow, with the flash of white in his tail-feathers. His song always starts with two dreamy, contralto notes and dies away in a spray of soprano twitterings. Then there were the silver flute-notes of the little pink-beaked field sparrow, which they were to hear later across darkling meadows, and the strange minor strains of the white-throated sparrow. Before long, a sudden thirst came upon Sergeant Henny-Penny. Fortunately they were near the bubbling spring that marked the beginning of Fox Valley, and the whole Band halted and drank in the most advanced military manner, to wit, by bending the rims of their felt hats into a cup. This method the Captain assured them was far superior to the more usual system of lying flat on their tummies, and had the approval of all great military leaders from Gideon down. Right in the very midst of their drinking, there sounded from the thicket a hurried warble of a mellow timbre, the wood-wind of the sparrow orchestra, and they caught a fleeting glimpse of the gray and tawny which is worn only by the fox sparrow, the largest of the sparrows and the sweetest and rarest singer of them all. A moment later a song sparrow sang. When he stopped, the strain was taken up by the fox sparrow in another key. Three times through he sang the twelve-note melody of the song sparrow, and his golden voice made the notes of the other sound pitifully thin and reedy. Then the fox sparrow threw in for good measure a few extemporaneous whistled strains of his own, and seemed to wait expectantly--but the song sparrow sang no more.
