In a great stone basin back of the parsonage, the boy made his first aquarium. There he gathered fishes, frogs, tadpoles, indeed, everything which he could obtain from Lake Morat. In the house he had pet birds, hares, rabbits, field-mice, with their families, all cared for as though they were royal visitors. He was skilful as a carpenter and boot-maker. When the village cobbler came to the house, two or three times a year, to make shoes for the family, the lad was quick to imitate him, and made well fitting shoes for his sister's dolls. Mrs. Elizabeth Cary Agassiz, in her fascinating life of her husband, tells this incident of his boyhood: "Though fond of quiet, indoor occupation, he was an active, daring boy. One winter day, when about seven years of age, he was skating with his little brother Auguste, two years younger than himself, and a number of other boys, near the shore of the lake. They were talking of a great fair held that day at the town of Morat, on the opposite side of the lake, to which M. Agassiz had gone in the morning, not crossing upon the ice, however, but driving around the shore. "The temptation was too strong for Louis, and he proposed to Auguste that they should skate across, join their father at the fair, and come home with him in the afternoon. They started accordingly. The other boys remained on their skating ground till twelve o'clock, the usual dinner hour, when they returned to the village. Mme. Agassiz was watching for her boys, thinking them rather late, and, on inquiring for them among the troop of urchins coming down the village street, she learned on what errand they had gone. Her anxiety may be imagined. The lake was not less than two miles across, and she was by no means sure that the ice was safe. "She hurried to an upper window with a spy-glass, to see if she could descry them anywhere. At the moment she caught sight of them, already far on their journey, Louis had laid himself down across a fissure in the ice, thus making a bridge for his little brother, who was creeping over his back. Their mother directed a workman, an excellent skater, to follow them as swiftly as possible. He overtook them just as they had gained the shore, but it did not occur to him that they could return otherwise than they had come, and he skated back with them across the lake. Weary, hungry, and disappointed, the boys reached the house without having seen the fair or enjoyed the drive home with their father in the afternoon." At ten, Louis was sent to a school for boys at Bienne, where, though the children studied nine hours a day, the time was wisely divided between work and play, so that they were kept well and happy. The lad always remembered affectionately his teacher at this school, Mr. Rickly. When the vacations came, Louis and Auguste walked twenty miles home to Motier, and did not find the journey long or tedious.
