The Children's Pilgrimage by L.T. Meade

Full of his idea, Maurice slept very little more that night. He tossed from side to side on the pine needles. But though he felt often drowsy, he was afraid to yield to the sensation; and early, very early in the morning, before the sun had risen, he got up. Going to the door of the hut, he stood there for a moment or so looking down into the forest. Just around the little hut there was a clearing of trees; but the forest itself looked dark. The trees cast long shadows, and Maurice felt rather nervous at the idea of venturing into their gloom. Suddenly, however, he heard a bird sing clear and sweet up into the sky, and the next moment two squirrels darted past his feet.

These two events decided him: the day was coming on apace, and soon Cecile and Joe would wake and begin to prepare for their journey. Without waiting to look around, he stepped into the dark shadows of the trees; and, in a moment, his little figure was lost in the gloom. To enable him to creep very quietly away -- so quietly that even Toby should not awake -- he had decided not to put on his shoes and stockings, and he now ran along the grass with his bare feet. He liked the sensation. The grass felt both cool and soft, and he began to wonder why he had ever troubled himself with such clumsy, tiresome things as shoes and stockings.
