We are grateful for the light which the letters already quoted cast upon the years Fulton spent in England, for, until their discovery, this period was obscure. After he had attained fame, his letters and drawings were treasured, but as a humble student in a strange land, it was difficult to follow his routine of life. At the close of a hundred years, when the city of New York celebrated the discovery of the Hudson River and Fulton’s successful steam navigation upon it, descendants of Fulton’s sisters lent to the New York Historical Society for exhibition, these interesting documents which throw some light on the early years of the inventor’s life. They had been treasured by his dear old mother on that distant Pennsylvania farm, and handed down through several generations to the present owners. CHAPTER VI FROM ART TO INVENTION If you had been working very hard, and suddenly received an order from an influential man to do a responsible piece of work for him, you would be very happy over it. Such a pleasure came to Robert Fulton in 1791, when Lord Courtenay, the Earl of Devon, invited the young artist to visit his famous country estate, Powderham Castle, during the vacation month of June, to paint his lordship’s portrait. The castle in Devonshire, which is one of England’s most beautiful counties, was about two hundred miles from London. There the Earl lived in princely grandeur, and admitted to his court only persons of equal rank; all others were entertained by his steward, a gentleman of birth and education. This visit proved a turning-point in Fulton’s life. With high hope he made the journey by stage-coach, reveling in the springtime glory of the wooded country-side. The study of the art treasures in the castle, and his appreciation of them, led to a later tour of other famous country-estates in England, and he became familiar with the great masterpieces of painting which hung in the spacious private galleries of the nobility, for Lord Courtenay, pleased with Fulton’s fulfilment of the intrusted commission, introduced him to all his friends. It was a novel and valuable experience for the young man. Devonshire is noted for its scenic beauty and healthful climate: so the trip not only gave the hard-worked student a beneficial change of air and scene, but also put money in his purse, and quieted the fears of possible failure which had occasionally disturbed his peace of mind. Once again Fulton himself shall tell us, through this quaint and delightful letter to his mother, of the pleasant change which had befallen him: DEVONSHIRE, Jan’ry 20th, 1792. MY DEAR MOTHER,
