Relatives and friends of Dr. Swain had carefully preserved many of her letters; and Dr. Greene, who had long desired that these letters should be published, conceived that the favorable time had come and urged the immediate preparation of the work. The letters were read, extracts made, compiled and edited; and in the summer of 1909 "A Glimpse of India" was given to the public. This furnished a most interesting record of the busy life of the first medical missionary to the women of the orient. As long as Dr. Swain was able, she attended the Sunday morning service and the Thursday evening prayer meeting, as well as the meetings of the missionary and the Ladies' Aid societies of the church. When she was no longer equal to the walk to church, she and her friend had regular Sunday morning service in their room with hymns, Scripture reading, prayer and a sermon, and were often present in spirit at the midweek prayer meeting, though their prayers and praises were uttered in their room.
