About sixty miles north of the city of New York, a range of lofty highlands crosses the Hudson, nearly from west to east, which passes under the name of the Fishkill mountains. The river has cut away this mighty barrier for the space of two or three miles, but it rises on either side and lifts its blue summits almost to the clouds. At the foot of the eastern portion of this range is now the pretty village of Fishkill, and scattered along the banks of the river are the luxurious country-seats of the De Wints, Verplancks, and other old Dutch families. But our story goes back for nearly a century, to a period when there were only a few scattered settlements along the banks of this noble river, and while yet the savage, the bear, and the panther were found in the forest. At this time, a man, who bore the semblance of a gentleman, purchased a large tract of land along the bank of the river, and at the distance of two or three miles from the eastern branch of the mountains we have described. Here he caused a large mansion to be constructed in the Dutch fashion, and having laid out his grounds with considerable care, he removed hither with his wife, and a large retinue of servants. He bore the name of Hielder, and supported the style and figure of a man of fortune. After a few years he had a child, a daughter, which became the special object of the care and attention of both parents. Hielder himself was a somewhat stern and gloomy man, and he seemed to impress his character upon everything around him. The mansion was deeply imbedded in the tall trees, and the apartments, wainscotted with oak and feebly lighted, had a peculiarly sombre aspect. The servants gradually assumed a dark and mysterious look, and the lady herself, though very beautiful, was always dressed in black, and was distinguished by a complexion of almost deathlike paleness. Several years passed, and the little girl, who was named Katrina, might now be seen walking with her mother amid the long, straight, shady avenues that were cut in the forest. Excepting the persons connected with the establishment, few persons visited the spot; it was therefore marked with peculiar loneliness, which seemed to increase the gloomy and mysterious aspect of the place. The proprietor of the mansion had no intercourse whatever with the people of the vicinity, and never, except once a year, when he made a short visit to the city of New York, did he leave his residence. He spent much of his time in reading, and devoted several hours each day to the instruction of his child, who now seemed to be the only object of his affections. It appeared indeed that there was some deep-rooted bitterness at his heart, which he attempted to alleviate by the education of his daughter.
