own religion, ignorance of the simplest elements of truth. I believe that an evangelist, thoroughly master of the language, Arabic, might go from village to village all over Yemen preaching, or quietly _speaking_ the gospel.” This testimony is true. But the challenge has never yet been accepted and all the highlands are still waiting for the first news of the gospel. Speaking of the capital of Yemen the report goes on: “Sana is a most important point. _It is impossible to exaggerate its importance from a missionary point of view._ It is in the centre of the finest races of Southern Arabia, and if a mission could be established there, its influence would extend on all sides to a multitude of tribes otherwise shut out from the gospel.” After reviewing in detail the open doors in every part of Arabia, and speaking of the special obstacles at each point together with the best methods of inaugurating work, he writes toward the end of his report: “_In one degree or another then, all Arabia is, I consider, open to the gospel._ It is as much open to it as the world generally was in apostolic times, that is to say, it is accessible to the evangelist at many different points, at all of which he would find men and women needing salvation, some of whom would receive his message, while others would reject it and persecute him. In some parts of the country he would not be molested or interfered with by the ruling powers; in others, as in Turkish Arabia, he might be arrested and even deported. Dangerous fanatics are, I believe, seldom met with but occasionally the missionary might come across such, and then the consequences might be more serious. But what if his lot were even worse than this, if he were hunted from village to village, and persecuted from city to city? Our Lord contemplated no other reception for His disciples when He sent them forth. This was in fact His ideal of the missionary life.... ‘When they persecute you in this city, (abandon the country? No.) flee ye into another.’ The evangelist in Arabia need expect nothing worse than this and even this would probably be of rare occurrence.... There is no difficulty then about preaching the gospel in Arabia if men can be found to face the consequences. The real difficulty would be the protection of the converts. Most probably they would be exposed to violence and death. The infant church might be a martyr church at first like that of Uganda, but that would not prevent the spread of the truth or its ultimate triumph.” The most remarkable thing about this report, which occupies only forty pages, is its prophetic character, its permanent value and the fact that it touches every phase of the problem still before us.
