Miss Nightingale was much disheartened, but she persevered. She corresponded with everybody of importance whom she could hope to influence. With Lord Lytton, who had succeeded Lord Northbrook as Viceroy in 1876, she was not acquainted; and Lord Beaconsfield she never approached, except on another matter, and then without any encouragement on his part.[171] In April 1878 Lord Salisbury became Foreign Secretary, and was succeeded at the India Office by Mr. Gathorne-Hardy (Lord Cranbrook), Mr. Edward Stanhope becoming Under-Secretary. Mr. Stanhope came to see her (June 1878); and in the following year she sent him the figures of mortality in the last Indian famine, which she had compiled with great labour from various sources of information, and correspondence ensued. She saw and corresponded largely with Sir James Caird, the English representative on the Famine Commission. She tried to incense Lord Houghton on the subject of Indian grievances. She saw and corresponded with Mr. Fawcett. She saw Mr. Bright. She kept up a large and regular correspondence with officials in India. She supplied materials for lectures in England; and, with skilled assistance, she had some maps drawn and engraved, to show the principal works which might be constructed. These maps did service at lectures; and Miss Nightingale also wrote repeatedly in newspapers and magazines--heralding "water-arrivals,"[172] pointing out districts which famine had not visited owing to previous irrigation, and others where similar works might be expected to prevent famine in future; comparing the cost of relief and prevention; urging the importance of extending education; calling attention to oppression in forms of land-tenure and by money-lenders; and generally seeking to arouse public interest at home in the life and sufferings of the voiceless millions in India. [171] In 1879 the Registrar-General retired, and Miss Nightingale wrote to Lord Beaconsfield urging the claims of Dr. Farr to the post. As the greatest of English statisticians, and as the senior in the Registrar-General's office, he would have been the right man, but Lord Beaconsfield gave the appointment to Sir Brydges Henniker. Dr. Farr thereupon retired from the Public Service. In the following year he was made C.B. (at Miss Nightingale's instance, through Sir Stafford Northcote).
