"Then we might as well sit down," suggested Uncle Felix, and suiting the action to the word, chose a nice soft spot upon the mossy bank and made himself comfortable as though he meant to stay; the Tramp did likewise, gathering the children close about his tangled figure. For one thing a big ditch faced them, its opposite bank overgrown with bramble bushes, and for another the sloping moss offered itself invitingly, like a cushioned sofa. So they lay side by side, watching the empty ditch, listening to the faint trickle of water tinkling down it. Slender reeds and tall straight grasses fringed the nearer edge, and, as the wind passed through them with a hush and whisper, they bent over in a wave of flowing green. "He's certainly gone that way," Judy whispered, following with her eyes the direction of the bending reeds. She was getting expert now. "Along the ditch, I do believe," agreed Tim. There were no flowers in it, and few, perhaps, would have found beauty there, yet the pointing of the reeds was unmistakable. "It's chock full of stuff," he added, "but a rat could get along, so I suppose--" "The signs are very slight sometimes," murmured the Tramp, his head half buried in the moss, "and sometimes difficult as well. You'd be surprised." He flung out his arms and legs and continued laughingly. "When things are contrary you may be sure you're getting somewhere--getting warm, that is." The children heard this outburst, but they did not listen. They were absorbed in something else already, for the movements of the reeds were fascinating. They began to imitate them, swaying their heads and bodies to and fro in time, and crooning to themselves in an attempt to copy the sound made by the wind among the crowded stalks. "Don't," objected Uncle Felix, half in fun, "it makes me dizzy." He was tempted to copy them, however, and made an effort, but the movement caught him in the ribs a little. His body, like his mind, was not as supple as theirs. An oak tree or an elm, perhaps, was more his model. "Do," the Tramp corrected him, swaying as he said it. "Swing with a thing if you want to understand it. Copy it, and you catch its meaning. That's rhythm!" He made an astonishing mouthful of the word. The children overheard it. "How do you spell it?" Judy asked. "I don't," he replied; "I do it. Once you get into the"--he took a great breath--"rhythm of a thing, you begin to like it. See?"
