Mr. Knapp's health forbidding a longer residence at Diarbekir, he commenced, in May, 1858, a new station at Bitlis, a healthy place several thousand feet above the level of the sea. Dr. and Mrs. Haskell were with them during the latter half of the summer, and spent the summer of 1859 at Mardin; but Mr. and Mrs. Marsh and Mrs. Lobdell decided to remain at Mosul. In May, Mr. and Mrs. Marsh were called to part with their second and only surviving child. A fortnight later, Mrs. Marsh herself had a severe attack of fever, but soon recovered. The fatal attack was three months later, and her death occurred unexpectedly. The thermometer in the early part of the night before, stood at 113º. During the day it was 120º; and on the night of her death it was 100º on the roof, where they slept. She had had a slight illness for a few days, and it now became a burning fever, with delirium, and all remedies proved vain. She died on the 12th of August, at the age of thirty-two, after a residence of six years at Mosul, as an earnest and faithful laborer. Her mother and her only sister had died before reaching the age of thirty, and it is possible Mrs. Marsh might not have lived as long in her native land, as she did at Mosul. "Yet it is probable," as her husband wrote at the time, "that the heat, so unusually extreme, cutting the leaves from the tree in our court by thousands, and causing many natives of the country to fall dead by the roadside, was the immediate occasion of her death." Mrs. Lobdell found reason, in the necessities of her children, for returning to America, and in April, 1860, she bade adieu to the little band of women, who, for eight years, had sat at her feet to learn of Jesus. She reached her native land in August, in company with Mr. Marsh. Mosul remained unoccupied during the summer, the heat at that season being found too great for endurance; though the climate is agreeable for nearly three fourths of the year. The summer retreat prepared by Dr. Lobdell at Deira, near Amadiah, was distant seventy miles, or four days' travel, and it required at least nine days to reach Mardin.
