Young Billy Clark, standing behind his father's bar and dealing out intoxicating drinks, was in a position to observe thoroughly the pernicious effects of dallying with alcohol. His daily occupation was an open book, as thrilling as lurid chapters of fiction, and the letters of it remained upon his soul in characters of unquenchable fire. Abraham Lincoln, when a young man, having gone down the Mississippi as a flat-boatman, visited the slave market of New Orleans. He was deeply affected by the harrowing scenes he there beheld, and he registered a vow that should ever the opportunity present itself, he would strike with all his power the institution that encouraged such iniquities. Thus was planted the germ that budded, blossomed and bore fruit in the Proclamation of Emancipation. No doubt it was the memory of his father's bar-room, with the evils radiating from it, that urged forward Dr. Clark to the culmination of his great destiny. Some writers give the name of Dr. Clark as William J. or W. J. Clark, but he himself signed it, B. J. Clark, while the best authorities refer to him as Dr. Billy J. Clark. It is probable that Dr. Clark, becoming widely known by the more familiar title, found it convenient to substitute the same for William. When about fifteen years of age, his father having died, young Clark returned to Northampton to attend school there for a term of one year. This experience was probably of great benefit to the youth, not only in improving his education, but by introducing him to one of the most refined and intelligent communities in New England. The inspiration of the life of Edwards was dominant in the society of the old town, and his books were still treasured and read. It is interesting to reflect that the living spirit of the great divine may have been a quickening influence in the heart of this thoughtful youth; that the story of the heroic life of Brainerd may have appealed to his religious and enterprising nature; that the memory of one or both of these devoted men may have contributed to the molding of his mind into the worthy fashion in which it subsequently displayed itself to the world. Be this as it may, not long after his return to the farm, he abandoned the bar and began the study of medicine under Dr. Caleb Gibbs, of Pownal. Still making his home at the farm, he pursued his studies for the space of two years, remunerating his preceptor by assuming the care of his horses. We find him at the end of that period, in 1797, entering as a student the office of Dr. Lemuel Wicker, of Easton, Washington County, N. Y., with whom he remained until March 21, 1799, when he began the practice of medicine in the town of Moreau. He opened his office not far from what afterwards became known as Clark's Corners. This historic neighborhood is situated about three miles in a westerly direction from Fort Edward, and five miles south of Glens Falls. Here, having married
