Miss Nightingale's main work during these years may be described as that of a Health Missionary for India. She carried on her mission in three ways. She endeavoured by personal interviews and correspondence to incense with a desire for sanitary improvement all Indian officials, from Governors-General to local officers of health, whom she could contrive to influence. She made acquaintance with natives of India and strove to spread her gospel among them in their own country. And through her "own little Department" in co-operation with Sir Bartle Frere she did a large amount of official work in the same direction. On her return to London at the beginning of October 1868, she found work awaiting her under the first of the foregoing heads. Sir John Lawrence's term of office of Governor-General was coming to an end, and Disraeli had appointed Lord Mayo to succeed him. On October 22 he wrote asking to be allowed to see Miss Nightingale before he sailed for India:-- (_Sir Bartle Frere to Miss Nightingale._) INDIA OFFICE, _Oct._ 23 [1868]. I think you will hear from Lord Mayo, who I know is anxious to see you, if you can grant him an interview next week. Could you in the meantime note down for him, as you did (when describing what the folk in India should now do) in a note to me a few weeks ago, the points to which he should give attention? I think you will like him very much. In appearance he is a refined likeness of what I remember of O'Connell when I went as a boy (with a proper horror of his principles) to hear him before he got into Parliament. Lord Mayo is very pleasing in manner, with no assumption of "knowing all about it," and evidently better informed on many subjects connected with sanitary reform than many men of greater pretension. He has a great sense of humour, too, which is a great help. I wish, when you see him, you would ask to see Lady Mayo. The interview with Lord Mayo was on the 28th, and a few days later Miss Nightingale saw Lady Mayo also. On the morning of the 28th Dr. Sutherland was summoned to South Street. He was in a hurry and hoped there was "nothing much on to-day." "There is a 'something,'" ran the message sent down to him, "which most people would think a very big thing indeed. And that is seeing the Viceroy or Sacred Animal of India. I made him go to Shoeburyness yesterday and come to me this afternoon, because I could not see him unless you give me some kind of general idea what to state." Dr. Sutherland, thus prettily flattered, stayed, and they discussed what should be said to the Sacred Animal. Next day she reported the conversation to Dr. Sutherland:--
