Her work as a foreign missionary was quickly finished. She labored longer as a home missionary among the Mohegans, who lived in the neighborhood of Norwich, and there displayed most conspicuously the moral heroism of her nature. In conjunction with Sarah Breed, she commenced her philanthropic operations in the year 1827. "The first object that drew them from the sphere of their own church was the project of opening a Sunday-school for the poor Indian children of Mohegan. Satisfied that this was a work which would meet with the Divine approval, they marked out their plans and pursued them with untiring energy. Boldly they went forth, and, guided by the rising smoke or sounding axe, followed the Mohegans from field to field, and from hut to hut, till they had thoroughly informed themselves of their numbers, condition, and prospects. The opposition they encountered, the ridicule and opprobrium showered upon them from certain quarters, the sullenness of the natives, the bluster of the white tenants, the brushwood and dry branches thrown across their pathway, could not discourage them. They saw no 'lions in the way,' while mercy, with pleading looks, beckoned them forward." The Mohegans then numbered a little more than one hundred, only one of whom was a professor of religion. She was ninety-seven years of age. In her hut the first prayer-meeting and the first Sunday-school gathered by these young ladies, was held. Miss Breed soon removed from that part of the country, and Miss Huntington continued her labors for awhile alone. She was at that time very active in securing the formation of a society and the circulation of a subscription, having for their object the erection of a chapel. She found, ere long, a faithful co-worker in Miss Elizabeth Raymond. They taught a school in conjunction, and, aside from their duties as teachers, were, at times, "advisers, counsellors, law-givers, milliners, mantua-makers, tailoresses, and almoners." The school was kept in a house on Fort Hill, leased to a respectable farmer, in whose family the young teachers boarded by alternate weeks, each going to the scene of labor every other Sunday morning, and remaining till the evening of the succeeding Sunday, so that both were present in the Sunday-school, which was twice as large as the other.
