In May 1875 she offered her services to the Foreign Mission Board. Her heart was set on Calabar, but so eager was she to be accepted that she said she would be willing to go to any other field. Women agents had long been engaged in Calabar. The first, Miss Miller, had gone out with Mr. Waddell in l849-she became the "Mammy" Sutherland who did such noble service-and they were playing an ever more important part, and were stated to be both "economical and effective." Requests had just been made for additions to the staff. The application was, therefore, opportune. Her personality, and the accounts given of her character and work, made such an impression on the officials that they reported favourably to the Board, and she was accepted as a teacher for Calabar and told to continue her studies in Dundee. In December it was decided to bring her to Edinburgh, at the expense of the Board, for three months, for special preparation.... The night before she left Dundee, in March 1876, she stood, a tearful figure, at the mouth of the "close" where she lived. "Good-bye," she said to a friend, and then passionately, "Pray for me!" VII. THE THREE MARYS A stranger in Edinburgh, Mary Slessor turned instinctively to Darling's Temperance Hotel, which was then, and is still, looked upon as a home by travellers from all parts of the globe. The Darlings, who were associated with all good work, were then taking part in the revival movement of Messrs. Moody and Sankey, and the two daughters, Bella and Jane, were solo-singers at the meetings. The humble Dundee girl had heard of their powers, and she entered the hotel as if it were a shrine. Feeling very lonely and very shy, she attended the little gathering for worship which is held every evening, and was comforted and strengthened. She found a lodging in the home of Mr. Robert Martin, a city missionary, connected with Bristo Street congregation, and formed a friendship for Ms daughter Mary. By her she was taken to visit a companion, Mary Doig, who lived in the south side. The three became intimates, and shortly afterward Miss Slessor went to live with the Doigs, and remained with them during her stay in the city. It was a happy event for her. Warm-hearted and sympathetic, they treated her as one of the family. A daughter who was married, Mrs. M'Crindle, also met her, and a lifelong affection sprang up between the two. In later days it was to Mrs. M'Crindle's house the tired missionary first came on her furloughs.
