The next evening the boys of Lancaster sprang a surprise on that quiet but patriotic town. The authorities had forbidden the burning of candles on account of the scarcity caused by the War of Independence, and every one expected that second Fourth of July to pass off as quietly as any other day. But at dusk all the boys gathered at Rob Fulton's house, just outside town, and as soon as it was really dark proceeded to the town square, their arms full of mysterious packages.
It took only a few minutes to gather enough wood in the centre of the square for a gigantic bonfire, and when all the people of Lancaster were drawn into the square by the blaze, the boys started their display of fireworks. The astonished people heard one dull thudding report after another, saw a ball of colored fire flaming high in the air, then a burst of myriad sparks and a rain of stars. They were not used to seeing sky-rockets, most of them had never heard that there were such things, but they were delighted with them, and hurrahed and cheered at each fresh burst. This was indeed a great surprise.
"What are they? Where did they come from? How did the boys get them?" were the questions that went through the watching crowds, and it was not long before the answer traveled from mouth to mouth: "It's one of Rob Fulton's inventions. He read about making them in some book."
The father of one of Robert's friends nodded his head when he heard this news, and said to his wife: "I might have known it was young Rob; I've never known such a boy for making things. His schoolmaster told me the other day that when he was only ten he made his own lead pencils, picking up any bits of sheet lead which happened to come his way, and hammering the lead out of them and making pencils that were as good as any in the school."
The fireworks were a great success; for the better part of an hour they held the attention of Lancaster, and when the last rocket had shot out its stars every boy there felt that the Fourth of July had been splendidly kept. For a day or two Rob Fulton was an important personage, then he dropped back into the ranks with his schoolmates.
It was not long after, however, that Robert set himself to work out another problem. The Fultons lived near the Conestoga, and Robert and his younger brothers were very fond of fishing. All they had to fish from was a light raft which they had built the summer before, and this cumbersome craft they had to pole from place to place. When they wanted to fish some distance down from their farmhouse, they had to spend most of the afternoon poling, and this heavy labor robbed the sport of half its charm. So, a week or two after the Fourth of July, Robert told a couple of boy friends that he was going to make a boat of his own, and got them to help him collect the materials he needed.
