Then the car stopped in response to a signal, and a tiny, evidently aged, woman with the activity of a child sprang on board. She had a large bag which she bore on one meagre little arm as if it had been a feather. Her wrinkled little face, rosily colored with the cold air, peeped alertly from under quite a fine, youthful hat trimmed with smart bows and a wing, but set crookedly on the head. Her sparse gray hair was strained tightly back from her thin temples and wound tightly at the back. Although she was undoubtedly old, her face could no more be called old than could that of a bird. She kept it in constant motion, bringing bright eyes to bear upon the different passengers. She did not travel very far. She stopped the car, springing alertly to her feet and pulling the bell-rope. Then she hopped off as spryly as a sparrow, on her thin ankles, moving with nervous haste. Then it was that Carroll noticed the boy for the first time, although he was seated directly opposite, and the child looked long and intently at the man. When the strange, agile old woman ran through the car, the boy looked across with a look of innocent fun at the man, and for the first time the two pairs of eyes met. It was not in Carroll, whatever his stress of mind, to meet a smile like that without response. He smiled back. Then the boy ducked his head with fervor, and off came his little cap, like a gentleman. He was a handsome little fellow, younger than Eddy by a year or two, fair-haired and blue-eyed, with a most innocent and infantile expression. He was rather poorly dressed, but he looked well cared for, and he had the confident and unhesitating regard of a child who is well-beloved. He had a little package of school-books under his arm.
