Caleb was a bright-looking, blue-eyed boy, with auburn hair and happy countenance. And yet he was rather pale and slender. He had been sick. His father and mother lived in Boston, but now he was spending the summer at Sandy River country, with his grandmother. His father thought that if he could run about a few months in the open air, and play among the rocks and under the trees, he would grow more strong and healthy, and that his cheeks would not look so pale.
