There were the imitations of the crowing of cocks, and braying of donkeys, and the sound of horns, encored and increased by the cheers of the boys. Then began the torpedoes, and the Antiques and Horribles had Chinese crackers also. And, in despair of sleep, the family came down to breakfast. Mrs. Peterkin had always been much afraid of fire-works, and had never allowed the boys to bring gunpowder into the house. She was even afraid of torpedoes; they looked so much like sugar-plums she was sure some the children would swallow them, and explode before anybody knew it. She was very timid about other things. She was not sure even about pea-nuts. Everybody exclaimed over this: “Surely there was no danger in pea-nuts!” But Mrs. Peterkin declared she had been very much alarmed at the Centennial Exhibition, and in the crowded corners of the streets in Boston, at the pea-nut stands, where they had machines to roast the pea-nuts. She did not think it was safe. They might go off any time, in the midst of a crowd of people, too! Mr. Peterkin thought there actually was no danger, and he should be sorry to give up the pea-nut. He thought it an American institution, something really belonging to the Fourth of July. He even confessed to a quiet pleasure in crushing the empty shells with his feet on the sidewalks as he went along the streets. Agamemnon thought it a simple joy. In consideration, however, of the fact that they had had no real celebration of the Fourth the last year, Mrs. Peterkin had consented to give over the day, this year, to the amusement of the family as a Centennial celebration. She would prepare herself for a terrible noise,--only she did not want any gunpowder brought into the house. The little boys had begun by firing some torpedoes a few days beforehand, that their mother might be used to the sound, and had selected their horns some weeks before. Solomon John had been very busy in inventing some fireworks. As Mrs. Peterkin objected to the use of gunpowder, he found out from the dictionary what the different parts of gunpowder are,--saltpetre, charcoal, and sulphur. Charcoal, he discovered, they had in the wood-house; saltpetre they would find in the cellar, in the beef barrel; and sulphur they could buy at the apothecary’s. He explained to his mother that these materials had never yet exploded in the house, and she was quieted. Agamemnon, meanwhile, remembered a recipe he had read somewhere for making a “fulminating paste” of iron-filings and powder of brimstone. He had written it down on a piece of paper in his pocket-book. But the iron filings must be finely powdered. This they began upon a day or two before, and the very afternoon before laid out some of the paste on the piazza. Pin-wheels and rockets were contributed by Mr. Peterkin for the evening.
