When Calvin was about five years old, his parents bought a farm twelve miles north of Gettysburg, near what is now York Springs, in Adams County. It is some twenty miles from the place of his birth, and beyond the limits of the Cumberland valley. Even now it is a comparatively out-of-the-way spot, reached only by a long drive from the nearest railway station; then it was so secluded that the Mateers called the house into which they removed the “Hermitage.” Here the family continued to reside until about the time of Calvin’s graduation from college. Then a second and much longer move was made, to Mercer County, in western Pennsylvania. Still later, a third migration brought them to Illinois. It is to the home in Adams County that Calvin refers in the line quoted at the head of this chapter, as the place where “were all the fond recollections and associations” of his youth. The farm was not very large, and the soil was only moderately productive, notwithstanding the labor and skill that the Mateers put upon it. In picking off the broken slate stones which were turned up thick by the plow, the children by hard experience were trained in patient industry as to small details. At least the two elder frequently beguiled the tedium of this task “by reciting portions of the Westminster Catechism and long passages of Scripture.” Another really tedious occupation, which, however, was converted into a sort of late autumn feast of ingathering, was shared by the whole family, but was especially appreciated by the children. This was the nut harvest of the “shellbark” hickory trees of the forest. As many as fifty or more bushels were gathered in a season; the sale of these afforded a handsome supplement to the income of the household. Along the side of the farm flows a beautiful stream, still bearing its Indian name of Bermudgeon, and in front of the house is a smaller creek; and in these Calvin fished and set traps for the muskrats, and experimented with little waterwheels, and learned to swim. Up on an elevation still stand the old house and barn, both constructed of the red brick once so largely used in the eastern section of Pennsylvania. Both of these are still in use. Though showing signs of age and lack of care, they are witnesses that for those days the Mateers were quite up to the better standard of living customary among their neighbors. “This growing family,” says Mrs. Kirkwood (Jennie), “was a hive of industry, making most of the implements used both indoors and out, and accomplishing many tasks long since relegated to the factory and the shop. Necessity was with them the mother not only of invention, but of execution as well. All were up early in the morning eating breakfast by candlelight even in summer, and ready before the sun had risen for a day’s work that continued long after twilight had fallen.” In the barn they not only housed their horses and cattle and the field products, but also
