“But you can see,” said Grandpapa, “and you can lend him your eyes.”
Sam looked so puzzled at this that his grandpapa explained: “You can tell him what you see, and he can imagine how everything looks. He will see the picture with his mind instead of with his eyes. That is imagination.”
“It is a very strange thing,” said Sam, thoughtfully.
“You see that blind people think so much about what they cannot see, that they make a great many pictures in their minds. If they were not able to do that, they would be very lonely.”
Then Sam hurried down to ask Cook to give him some bread for the birds, and to fill a basket with nuts for the squirrels. He also took some canary and hemp seeds in a little package. By the time this was done, the sleigh had driven up to the door, and Sam and his grandpapa started on their expedition, Sam throwing kisses to his grandmamma at the window so long as the house was in sight. Then they turned the corner and soon reached the engine-house.
Billy’s pale face grew quite rosy when he was told of the sleigh-ride he was to have, and in a moment his warm coat and cap were on and he was led to the sleigh by Sam, who took great care of him for fear he should make a misstep. The Fire-Dog followed closely at his heels, and watched him put into the big sleigh and securely tucked in with the warm fur robe.
“Can’t Jack go too?” asked Sam, as he saw the wistful expression in the faithful dog’s eyes.
“Certainly, if he will,” replied Grandpapa.
Jack, however, was not the dog to neglect his duties, and in spite of Sam’s and Billy’s alluring calls, he gently but firmly wagged his tail, to express his regret at being obliged to refuse their invitation. As they drove off, he looked mournfully after them so long as the sleigh was in sight, then he gave a sigh of disappointment and lay down in front of the engine-house, where he could enjoy the passing, and occasionally pass the time of day with some dog friend, or make the acquaintance of some stranger passing through the city, for Jack was a social dog. Here, too, he was within hearing of the gong.
Meanwhile the sleigh continued on its way to the park, the faces of the two little boys beaming with pleasure,—Billy’s at the unusual treat of a sleigh-ride, and Sam’s from watching the happiness of the little blind boy.
