Farmer Appleby was in what he called a fidget. He did not look nervous, and was not. But the word, along with several others he sometimes used, had come down to him from Scandinavian forefathers. The very name with its ending "by" showed that his farm was a part of the Danelaw. Along the coast, and in the part of England fronting the North Sea, Danish invaders had imposed their own laws and customs on the country, and were strong enough to hold their own even in the face of a Saxon King. It was only a few years since the Danegeld, the tax collected from all England to ward off the raids of Danish sea-rovers, had been abolished. But Ralph Appleby was as good an Englishman as any. Little by little the Danelaw was yielding to the common law of England, but that did not worry an Appleby. He did not trouble the law courts, nor did they molest him. The cause of his fidget was a certain law of nature by which water seeks the shortest way down. One side of his farm lay along the river. Like most of the Danish, Norse, Icelandic or Swedish colonists, his long-ago ancestor had settled on a little river in a marsh. First he made camp on an island; then he built a house on the higher bank. Then the channel on the near side of the island filled up, and he planted the rich soil that the river had brought with orchards, and pastured fat cattle in the meadows. Three hundred years later the Applebys owned one of the most prosperous farms in the neighborhood. Now and then, however, the river remembered that it had a claim on that land. The soil, all bound and matted with tough tree-roots and quitch-grass, could not be washed away, but the waters took their toll in produce. The year before the orchards had been flooded and two-thirds of the crop floated off. A day or two later, when the flood subsided, the apples were left to fatten Farmer Kettering's hogs, rooting about on the next farm. Hob Kettering's stubborn little Saxon face was all a-grin when he met Barty Appleby and told of it. It speaks well for the friendship of the two boys that there was not a fight on the spot.
