The bare idea of all he would do was exciting. As Jack sat by the fire in the kitchen or lay curled up in the window-seat listening to the horses which went by, he began to make his plans for the future. How fortunate it was that he was able to ride already!--why, most of the boys at school, who were not blind at all, had never been across a horse's back, far less galloped at full speed up and down the street as Jack had loved to do! So he, blind though he was, could do something which they could not, and had the start of them! Now that he could walk about the room without falling down from weakness he must lose no more time, but try and learn the positions of the chairs and tables and count exactly how many steps there were on the staircase, so that he might soon run up and down them as fast as he did before. The next thing was to trust himself in the street, and find his way about. He was rather shy at first, and felt a little bewildered, but he would not go home till he had gone as far as the baker's shop--up and down, up and down, several times over. 'Well, I can go _there_ all right, if mother sends me,' he said to himself, and walked home in triumph to tell his parents. Having once made a beginning, Jack never let a day pass without learning to do something fresh, till by the time he was nine he could carry messages to any part of Knaresborough as well as another boy. He had a good many friends of his own age, and with them he would go on expeditions into the woods near the town, and even climb trees after birds' eggs. Very quickly the boys discovered that Jack was a better climber than any of them. He was so light, and then he could tell by his sense of touch if a branch was rotten, or whether he might trust himself upon it, and it was not long before it was Jack who was always sent to the top of the tree while the rest remained at the bottom. His mother suffered agonies of fear at first during these hours that the boy was away, but she knew it was no use trying to hinder him, and after a while she ceased to trouble, as Jack never came to harm, and she had too much to do in looking after the younger children to worry about him. It was impossible to keep Jack in the house; if he was not in a tree, he was on the back of a horse or exercising a couple of young hounds that his father had given him; but when, about thirteen, he showed a liking for music, she had him properly taught, in the hope of inducing him to stay at home in the winter evenings.
