Jones worked so hard that made the sparks fly from his hammer．The son of Mr．Smith, a rich neighbor, used to come to see the blacksmith and he would enjoy himself watching how the tradesman worked．"Why don’t you try your hand to learn to make shoe tacks?" said the blacksmith．"Who knows, one day, it may be of use to you." The lazy boy began to see what he could do．But after a little practice he found that he was becoming very skilled and soon he was making some of the finest tacks.
Old Mr．Smith died and the son on account of the war lost all his goods．He had to leave home and was forced to take up residence in another country．It so happened that in this village there were numerous shoemakers who were spending a lot of money to buy tacks for their shoes and even at times when they paid high prices they were not always able to get what they wanted, because in that part of the country there was a high demand for soldiers’ shoes.
Young Smith, who was finding it difficult to earn his daily bread, remembered that he had learned the art of making tacks and had the sudden idea of making a bargain with the shoemakers．He told them that he would make the tacks if they would help to get him settled in his workshop．The shoemakers were only too glad of the offer．"How funny it seems," he used to say, "even making tacks can bring a fortune．My trade is more useful to me than were all my former riches."
