The school was kept up by a number of benevolent persons who contributed liberally to its funds. Sir William Johnson was ready to do his share to aid the good work, and some four months and a half after the Mohawk boys had arrived he wrote to the principal: 'I shall not be backward to contribute my mite.' A house in which to hold the classes and two acres of land had been given by a farmer named Joshua Moor; hence the institution was generally called Moor's Indian Charity School. The principal, Dr Wheelock, was a man of wide scholarship, and became later on the founder of the seat of learning in New Hampshire now known as Dartmouth College. But little is known of the course of study pursued by Joseph at Moor's School. When he entered it his knowledge must have been very slender, and as a young man he began to learn things ordinarily taught to a mere child. It is likely that he now became much more fluent than formerly in his use of the English tongue. From the beginning his progress was very rapid, and Dr Wheelock does not stint the praise that he bestows upon him: 'Joseph is indeed an excellent youth,' was his comment; 'he has much endeared himself to me, as well as to his master, and everybody also by his good behaviour.' The master here spoken of was Charles Jeffrey Smith, a young man of ample means who wished to be of service to the Indians. He had come to the school after Joseph's arrival and helped the principal in giving instruction. He very soon remarked the superior intelligence which Joseph showed among the twenty-five pupils in his charge. Intending to make a missionary tour among the Indian tribes, he proposed to take his young pupil with him as an interpreter. Writing to Sir William Johnson about the matter, he referred to Joseph in most glowing terms: 'As he is a promising youth, of a sprightly genius, singular modesty, and a serious turn, I know of none so well calculated to answer my end as he is.' It was with sad misgivings that Joseph thought of turning his back upon the school, where he had been for scarcely two years; but Smith promised to continue as his teacher when they were together in the Indian country, and to pay him something for his work as an interpreter. This appealed to the young redskin. It appeared that his schooldays were ended in any event, for his people were jealous of his prolonged stay in the lodges of the stranger and he had received a message calling him back to Canajoharie Castle. In the month of June 1763, master and pupil set out together, but, as fate would have it, Smith's quest among the tribes was to be quickly ended. Hardly had he begun his pilgrimage when he found the Indians in wild commotion. Again the hatchet had been unburied, and for the sake of security he had to bring his mission to an abrupt end.
