It was high hot noon on the Casket Ridge. Its very scant shade was restricted to a few dwarf Scotch firs, and was so perpendicularly cast that Leonidas Boone, seeking shelter from the heat, was obliged to draw himself up under one of them, as if it were an umbrella. Occasionally, with a boy's perversity, he permitted one bared foot to protrude beyond the sharply marked shadow until the burning sun forced him to draw it in again with a thrill of satisfaction. There was no earthly reason why he had not sought the larger shadows of the pine-trees which reared themselves against the Ridge on the slope below him, except that he was a boy, and perhaps even more superstitious and opinionated than most boys. Having got under this tree with infinite care, he had made up his mind that he would not move from it until its line of shade reached and touched a certain stone on the trail near him WHY he did this he did not know, but he clung to his sublime purpose with the courage and tenacity of a youthful Casabianca. He was cramped, tickled by dust and fir sprays; he was supremely uncomfortable-but he stayed A woodpecker was monotonously tapping in an adjacent pine, with measured intervals of silence, which he always firmly believed was a certain telegraphy of the bird's own making; a green-and-gold lizard flashed by his foot to stiffen itself suddenly with a rigidity equal to his own. Still HE stirred not.
