At that moment Sam, the hired man, came into the room. Mrs. Jones had missed Jack and sent Sam to find him. Jack was having a pleasant time and did not want to go home, but he knew how to obey, and, when Johnnie Jones commanded him to "go home," he turned slowly and walked out of the room.

So you see, Jack was turned out by the teacher, just as was Mary's lamb.

One bright day, when the ground was covered with snow, Father took Johnnie Jones for a ride on his sled. They had been around the block only twice when the clock struck two, and then it was time for Father to go to his office.

"Oh! dear," said Johnnie Jones, "now I'll have no one to pull my sled. I wish Jack could."

"Perhaps he can," Father answered. "When I come home to-night I'll make some sort of a harness for him, and then to-morrow we shall see what he can do."

That evening, with rope, straps, and Johnnie Jones's reins Father made a very good harness, and the next day he hitched Jack to the sled. At first Jack could not imagine what Father and Johnnie Jones wished him to do. He allowed himself to be hitched to the sled, but every time Johnnie Jones sat upon it, and said "Get up," Jack would jump about, and off would roll Johnnie Jones into the snow. Then Jack would bark as much as to say, "What are you trying to do, anyway?"

At last, after many trials, Father managed to hold Jack quiet until Johnnie Jones was seated firmly on the sled, clasping a side with each hand. Then Father, still keeping a tight hold of Jack, ran with him to the corner and back several times. At last Jack began to understand what was expected of him. The next day they tried again, and it was not long before Johnnie Jones could drive the big dog without Father's help. After a while Jack would even pull Johnnie Jones's sled to kindergarten each morning, and then draw the empty sled home, after Johnnie Jones had gone into the house. He certainly was a clever dog. It was no wonder Johnnie Jones loved him.

In the winter-time there was an excellent place for coasting in the park very near Johnnie Jones's house. There was a long, straight hill, and at the foot of it a long, straight pond, so that, with a good start, a child could coast from the top of the hill to the end of the pond. That is, of course, when there was snow and the pond was frozen over at the same time.

One afternoon Johnnie Jones started out with his sled and Jack ran along beside him.

"Don't try to coast across the pond to-day," called Father. "When I was passing I noticed that the ice was broken in several places."
