Every missionary has to do a good deal of visiting. All visits have not got to be returned, but a certain number must be. It is well not to return all visits, for otherwise it is difficult to get secret enquirers to come to your house, or people who are too poor to receive you in their own houses. The usual Persian habit is never to pay a visit without first of all asking leave, but though this rule has to be observed towards others, it is best to make it clear that your own house is an office, and only to insist on notice for visits of civility when they are made by people who are likely to prove awkward. Paying visits to Persian houses has a certain value to the missionary, as it introduces him to Persian life and manners, and puts him on easier terms with the natives, but it seldom affords the evangelistic missionary who is working amongst men his best opportunity for direct missionary work. There is too much publicity, and too many interruptions. The best missionary work is usually done on one’s own premises; and in Yezd I have known enquirers and visitors begin coming at six o’clock in the morning, and go on almost without intermission till ten o’clock at night; but at that time I was connected with scholastic work, which, although requiring only superintendence, advertised my presence in the town to a considerable degree. One of the things that is therefore most necessary in a place like Yezd for the evangelistic missionary is an absolutely well-ordered household. Everything ought to go by clockwork. Almost every visitor has to be treated as an ordinary social guest, and unless the arrangements are nearly perfect, either his attention or the missionary’s will be called away from the conversation. A missionary in such a position ought to pay close attention to the number and description of his tea-cups and pipes. One class of visitors ought to be properly served with silver-mounted hookahs and three tiny cups of very hot tea, brought in at intervals of ten minutes, and this without any previous notice to the servant. Another class of visitor ought to have a European cup of tea holding about three times as much as the Persian cup, and a box of cigarettes, so that he and his host may be able to talk without further interruption till the end of the interview. A third class of visitor, who has given notice, ought to be prepared for beforehand, and served with iced sherbet. Then again, a decision has to be made according to the status of the guest as to whether the missionary shall be served with tea at the same time or not. All this requires the most careful training of servants, and any inattention to detail may produce an atmosphere which makes teaching exceedingly difficult. Further, the servants have to know who should be shown into a private room, and who can be allowed to mix with other guests. These are just a few of the minor points which are nevertheless of real importance. To come to points which are obviously more serious.
