Thus, I was again left to myself. The schools were not the best, but all that could be done for me, in or out of them, was done. I had been especially well taught to sew and liked it, but knitting was beyond me. I could not be held to it, and it was given up. Through the confirmed invalidism of my elder sister, Dorothea, I lost her beautiful guidance, but the watchful care of my younger sister, now Mrs. Vassall, was truly pathetic. She never lost sight of my welfare, and her fine literary taste was a constant inspiration. While thus in the midst of my various pursuits and vocations, an accidental turn in my wheel of fortune changed my entire course (for a time at least) and how much bearing, if any, it may have had on the future, I have never been able to determine. I have spoken of the younger of my two brothers, of the firm of S. & D. Barton, as a fine horseman. He was more than that. In these days he would have been an athlete. The two men were but two years apart in age, of fine disposition and excellent physical strength, integrity and courage; of fine disposition and equable temper; yet neither of them men with whom an opponent would carelessly or tauntingly covet an encounter. The younger, David, from his physical activity and daring, was always selected for any feat of danger to be performed. These were days when even buildings were “raised by hand.” All the neighborhood was expected to participate in a “raising.” Upon one occasion, an uncommonly large barn, with what was then still more uncommon, a cellar beneath, was to be raised. The rafters must be affixed to the ridgepole, and David Barton was assigned to this duty. While in its performance, a timber on which he was standing, having been weakened by an unobserved knot, suddenly gave way, and he fell directly to the first floor, striking on his feet on another timber near the bottom of the cellar. Without falling he leaped to the ground, and after a few breathless minutes declared himself unhurt, but was not permitted to return aloft. It was spoken of as a “remarkable adventure,” “a wonderful escape,” etc., and for a few days all went well, with the exception of a slight and quite unaccustomed headache, which continued to increase as the July weather progressed. At length he showed symptoms of fever; the family physician was called, and here commenced a system of medical treatment quite unknown to our physicians of the present day, other than as results of historical research and milestones of scientific advancement.
