=18. Missionaries.= Miss Rice, a missionary in Constantinople, has a large school for girls. Some of her scholars live in Constantinople, but most of them are from abroad--different parts of Turkey and Western Asia. "In England, Scotland, Ireland, and Germany, females organize societies of their own, and send out teachers and readers of their own sex. Ladies in England have had a society there twenty-five years, expressly for sending out and sustaining single ladies to work for heathen women, and they have already themselves sent two hundred into the field, at a cost of many thousands of pounds. If any of the lady missionaries sent out by the ladies' society in England desire to leave the work within five years, they shall be at liberty to do so, but shall refund to that society the cost of sending them out." Mrs. Ellen B. Mason, a missionary of Burmah, is now in New York, endeavoring to obtain female missionaries to return with her. A lady (Mrs. Bigelow) was employed among the city missionaries in Boston, at a salary of $350. From the last reports of the American Board of Foreign Missions, the Old School Presbyterian, the Protestant Episcopal, the Methodist, and Dutch Reformed, we find 451 lady missionaries were supported by their Boards at the time of making out the reports. The American Board had in charge 185 among foreign nations, and among the Indians 41 = 226. Of those sent out by this Board, 26 are unmarried. The Old School Presbyterian has 78 among the Indians (33 unmarried), and among heathen 53 (3 of the number single) = 131. The Baptist Foreign Missions number 34 (none unmarried). The American Baptist Union require every lady and gentleman that go out as missionaries from their Board to marry before they go. The Dutch Reformed have 11 among foreign nations. The Protestant Episcopal have 26 foreign missionaries (all married). The Methodist 17 (2 unmarried). In a manual for the use of missionaries and missionary candidates in connection with the Board of Foreign Missions of the Presbyterian Church, we find the laborers needed for the foreign field are: 1st, ordained ministers of the gospel; 2d, physicians; 3d, school teachers; 4th, printers; 5th, farmers and mechanics; 6th, unmarried female teachers. In referring to all the other classes but the first mentioned, it reads: "Though not called to preach the gospel, their Christian profession requires from them the same devotedness to the cause of Christ, according to the circumstances in which the providence of God has placed them, that is required from the ministers of the gospel. The application should be in writing, and the candidate should state briefly his age, education, employment, the length of time he has been a professor of religion, his motive and reasons for desiring to be a missionary, the field he prefers, and the state of his health. For a female this information may be given through a third person. No person
