``The Government of the United States, while it claims to exercise, under and by virtue of the stipulations of treaty, the exclusive right of judging of the wrongful acts of its citizens resident in China, and of punishing them when found guilty according to its own laws, does not assume to claim or exercise any authority or control over the natives of China. This rule applies equally to merchants and missionaries, and, so far as I know, all foreign Governments having treaties with China adhere strictly to this rule. In case, however, missionaries see that native Christians are being persecuted by the local officials on account of their religious opinions, in violation of the letter and spirit of the twenty-ninth article of the treaty between the United States and China, it would be proper, and entirely in accordance with the principles of humanity and the teachings of their religion, to make respectful representation of the facts in such cases to the local authorities direct, or through their diplomatic representative to the foreign office; for it cannot be presumed that the Imperial Government would sanction any violation of treaty engagement, or that the local officials would allow persecutions for opinion's sake, when once the facts are made known to them. In doing this the missionaries should conform to Chinese custom and etiquette, so far as it can be done without assuming an attitude that would be humiliating and degrading to themselves.'' The question is one of the most difficult and delicate of all the questions with which the missionary must deal. On the one hand, every impulse of justice and humanity prompts him to befriend a good man who is being persecuted for righteousness' sake. But on the other hand, sore experience has taught him the necessity of caution. The pressure upon him is so frequent and trying that it becomes the bete noire of his life. The outsider may wisely hesitate before he adds to that pressure. The citations that have been given show that the missionaries themselves understand the question quite as well as any one else and that they are competent to deal with it.
