But he would have his Government sojourn during the hot weather of each year in the refreshing climate of the Himalayas. He had no hesitation in choosing Simla for this purpose, as being the only mountain station that could furnish house-accommodation for the influx of sojourners; as being easily accessible by rail and road at all seasons; as having politically a good position sufficiently near the North-western Frontier, yet not so near as to be within reach of danger; and as being immediately surrounded by a peaceful population. He was sensible of the natural beauty, the varied charms, the salubrious climate of the place, and his choice has been fully ratified by the Governors-General who have succeeded him. His Government, while sojourning at Simla, would transact all its administrative business for the time, and proceed with some parts of its legislation. But he would reserve for its residence at Calcutta all those bills or projects of law which might be of general importance, and wherein contact with public opinion might be specially desirable. He was now by the autumn of 1864, fairly launched on his career as Viceroy and Governor-General. His health had been slightly shaken by the change from England to Calcutta, of which the climate agreed with him less than that of any other place in India. But it soon revived in the Himalayan air. He kept up his early riding in the morning while at Calcutta, but was induced by the pressure of business to intermit it at Simla. However he took exercise in the afternoon fully, and so during this year and 1865 he remained fairly well; indeed during the summer of 1865 he was better than he had been for many years, that is since his Trans-Sutlej days. But he was not so well in 1866, and in the summer of 1867 he intimated to the Secretary of State, who was then Sir Stafford Northcote, that he might have to retire early in 1868 having completed his four years. The Secretary of State, however, on public grounds requested him to remain till the end of his five years if possible, that is till the beginning of 1869. So he braced his determination to remain his allotted term. He said in private that it would be a great satisfaction to him to serve out his time, and to hand over the work to his successor without any arrears. From 1867, however, he became weaker physically by slow, perhaps by imperceptible degrees, and that general condition naturally set up lesser ailments from time to time; while the clear brain and the unconquerable will remained.
