"Oh, certainly!" said Mr. Johnson. "Here it is. You may follow me." When they reached Mr. Johnson's house, the old man politely handed him the turkey and turned to go. "Here, my friend, what shall I pay you?" said the young gentleman. "Oh, nothing, sir, nothing," answered the old man. "It was no trouble to me, and you are welcome." He bowed and went on. Young Mr. Johnson looked after him and wondered. Then he turned and walked briskly back to the market. "Who is that polite old gentleman who carried my turkey for me?" he asked of the market man. "That is John Marshall, Chief Justice of the United States. He is one of the greatest men in our country," was the answer. The young gentleman was surprised and ashamed. "Why did he offer to carry my turkey?" he asked. "He wished to teach you a lesson," answered the market man. "What sort of lesson?" "He wished to teach you that no man should feel himself too fine to carry his own packages." "Oh, no!" said another man who had seen and heard it all. "Judge Marshall carried the turkey simply because he wished to be kind and obliging. That is his way." THE PADDLE-WHEEL BOAT More than a hundred years ago, two boys were fishing in a small river. They sat in a heavy flat-bottomed boat, each holding a long, crooked rod in his hands and eagerly waiting for "a bite." When they wanted to move the boat from one place to another they had to pole it; that is, they pushed against a long pole, the lower end of which reached the bottom of the stream. "This is slow work, Robert," said the older of the boys as they were poling up the river to a new fishing place. "The old boat creeps over the water no faster than a snail." "Yes, Christopher; and it is hard work, too," answered Robert. "I think there ought to be some better way of moving a boat." "Yes, there is a better way, and that is by rowing," said Christopher. "But we have no oars." "Well, I can make some oars," said Robert; "but I think there ought to be still another and a better way. I am going to find such a way if I can." The next day Robert's aunt heard a great pounding and sawing in her woodshed. The two boys were there, busily working with hammer and saw. "What are you making, Robert?" she asked. "Oh, I have a plan for making a boat move without poling it or rowing it," he answered. His aunt laughed and said, "Well, I hope that you will succeed." After a great deal of tinkering and trying, they did succeed in making two paddle wheels. They were very rough and crude, but strong and serviceable. They fastened each of these wheels to the end of an iron rod which they passed through the boat from side to side. The rod was bent in the middle so that it could be turned as with a crank. When the work was finished, the old fishing boat looked rather odd, with a paddle wheel on each side which dipped just a few inches into the water. The boys lost no time in trying it. [Illustration]
