Dr. Nelles's life, like that of most men of purely scholastic pursuits, has been comparatively uneventful, and does not form a very fruitful field for biographical purposes. It has, however, been an eminently useful one, and has been attended with results most beneficial to the educational establishment with which his name has long been associated, and over which he has presided for a continuous period of thirty years. He is of German descent, on both the paternal and maternal sides. His paternal grandparents emigrated from Germany to the State of New York sometime during the last century, and settled in the historic valley of the Mohawk, where some of their descendants still reside. There Dr. Nelles's father, the late Mr. William Nelles, was born, and there he passed the early years of his life. He married Miss Mary Hardy, who was also of German stock on the mother's side, and was born in the State of Pennsylvania. By this lady he had a numerous family, the eldest son being the subject of this sketch. The parents emigrated from New York State to Upper Canada soon after the close of the War of 1812-15, and devoted themselves to farming pursuits. The Doctor was born at the family homestead, in the quiet little village of Mount Pleasant--known to the Post Office Department as Mohawk--in what is now the township of Brantford, in the county of Brant, about five miles south-west of the present city of Brantford, on the 17th of October, 1823. At the present day, the schools of Mount Pleasant will bear comparison with those of many places of much larger population; but fifty years ago, when young Samuel Nelles was in attendance there, they were like most other schools in the rural districts of Upper Canada--that is to say, they afforded no facilities for anything beyond a very rudimentary educational training. Such as they were, however, they furnished the only means of instruction at his command until he had entered upon his seventeenth year. Previous to that time he had lived at home, attending school and assisting his father in farm work. He had, however, displayed great fondness for study, and had, by dint of his natural ability and steady application, made greater progress than could have been made by any boy who was not possessed by an ardent thirst for knowledge. His parents accordingly resolved that he should have an opportunity of following out the natural bent of his mind. In 1839 he was placed at Lewiston Academy, in the State of New York, where he spent an industrious year, and where he had for a tutor the brilliant, witty and humorous John Godfrey Saxe. Mr. Saxe was not then known to the world as a poet, but he was an accomplished philologist, and was reading for the Bar. He had just graduated at Middlebury College, Vermont, and was teaching _belles-lettres_ in the Lewiston Academy contemporaneously with the prosecution of his legal studies. In October, 1840, young Nelles
