After leaving the academy, Miss H. engaged as a teacher, and with considerable success employed herself in her vocation, in Haverhill, Salem, and Newbury. Teaching with her was not an ordinary employment; she remembered that her pupils had souls as well as bodies; and while she was striving to expand the youthful mind, she also endeavored to improve the youthful heart, and impress upon the conscience those lessons of truth which time could never efface. It was at the same conference in which the acquaintance between Mr. and Mrs. Newell commenced that Mr. Judson was introduced to the subject of this sketch. He was then in need of a companion who would share his anxieties, his labors, and his sorrows; and he fixed upon Miss Hasseltine as the one whose tastes and feelings most accorded with his own. He was probably attracted by her ardent piety, her brilliant intellect, and her joyous spirit. Having duly considered the subject, he gave her an invitation to go out with him to distant India, and be his companion in the brightest hour of his prosperity and in the darkest moment of his adversity. To decide the question was not an easy matter. It was connected with obligations which she did not hastily assume, and hence it was several months ere she had resolved to go. She was at times fearful that her disposition for what was in itself romantic and strange would bias her judgment and lead her to pursue a course which she should regret when too late to turn back. Hence she brought all her feelings and motives to a severe test, and looked down deeply into the hidden mystery of her heart. Before God she laid herself completely open, and sought, by humble supplication, his divine direction. With no example but that of Harriet Newell, who had just consecrated herself to the work, she decided to make India her home, and suffering and privation her lot. Her letters upon this subject, about this time, abound with passages of thrilling interest, and give evidence that the subject of missions absorbed her whole attention and pervaded her whole nature.
