Harriet Bradford Tiffany, afterwards the wife of the Rev. Charles S. Stewart, was born near Stamford, Connecticut, on the fourth of June, 1798. She lost her father when she was a small child, and till 1815, passed most of her time with an uncle, in Albany. At this date, an older sister married and settled in Cooperstown, and consequently Harriet took up her abode in that place. She became the subject of renewing grace in the summer of 1819; was married on the third of June, 1822, and sailed with her husband and nearly thirty other missionaries, all bound to the same field, on the nineteenth of November following. This little, heroic band, that, by the help of God, have since been mainly instrumental in making the Sandwich islands blossom like a rose, arrived at Honolulu, in Oahu, on the twenty-seventh of April, 1823.

Mrs. Stewart left a beautiful town in a thriving part of the Empire State; tempting luxuries; a brilliant circle, and many endearing friends; but she had embarked in a glorious enterprise for Christ's sake, and, hence, she settled down in a little log hut, in the town of Lahaiua, three days' sail from Oahu, contented and happy. On the first day of January, 1824, she wrote as follows: "It is now fifteen months since I bade adieu to the dear valley which contains much, very much, that is most dear to me; but since the day I parted from it, my spirits have been uniformly good. Sometimes, it is true, a cloud of tender recollections passes over me, obscuring, for a moment, my mental vision, and threatening a day of darkness; but it is seldom. And as the returning sun, after a summer shower, spreads his beams over the retiring gloom of the heavens, and stretches abroad the shining arch of promise to cheer the face of nature, so, at such times, do the rays of the Sun of Righteousness speedily illumine the hopes of my soul, and fill my bosom with joy and peace."

A few months after the above date, writing to a friend, she says: "We are most contented and most happy, and rejoice that God has seen fit to honor and bless us by permitting us to be the bearers of his light and truth to this dark corner of the earth. Could you feel the same gladness that often fills our bosoms, in witnessing the happy influence of the Gospel on the minds and hearts of many of these interesting creatures, you would be satisfied, yes more than satisfied, that we should be what we are, and where we are, poor missionaries in the distant islands of the sea."In these brief extracts from her letters, shines, in its serenest lustre, the character of the Christian heroine:[54] and it would be an easy task to compile a volume of letters written on the field of moral conflict by American female missionaries, breathing a spirit equally as unselfish, cheerful and brave. All pioneer women in this enterprise are heroines, and if the conflicts and sublime victories of all claiming American citizenship, are not herein recorded, it is because, in a work of unambitious pretensions as it regards size, a few characters must stand as representatives of a class.

So pernicious was the influence of a tropical climate that, in the spring of 1825, the health of Mrs. Stewart began to fail; and at the end of a year, she was forced to leave the country. She sailed, with her husband, for London; and after tarrying three months in England, they embarked for home. They reached the valley of the Otsego in September, 1826. For three or four years, it was the prayer of Mrs. Stewart that she might be restored to health and permitted to return to the mission station; but in January, 1830, she was laid on a bed of declension and suffering, and in the following autumn, fully ripe, was gathered into the heavenly garner.
