"Henderson, are you ill?" asked Dr. Leacraft, coming into the junior class-room about eleven o'clock, and noticing that Charlie Henderson, the youngest boy in the school and a pattern scholar, was deathly pale, and supporting his head upon his hand. The boy was subject to frightful headaches, which for the time unfitted him for all study or recitation; and Seabrooke, who was hearing the lesson in progress, had excused him from taking any part in it. These headaches were of few hours duration; but the boy needed absolute rest and quiet to enable him to conquer them.
