What degree of expense shall be incurred in the support of missionary families, so as to secure the greatest possible efficiency with a given amount of money; how to dispose of the children of missionaries, in a manner most grateful to their parents, and most creditable to the cause; in what proportion to spend money and time upon the education of the heathen, as a distinct thing from preaching the Gospel; how far the press should be employed; by what means the attention of the heathen can be best gained at the beginning; how their wayward practices and habits can be best restrained and corrected; how the intercourse between missionaries and the Christian world can be conducted in the best manner, so as to secure the highest responsibility, and the most entire confidence; and how the suitable proportion between ministers of the Gospel retained at home, and missionaries sent abroad, is to be fixed in practice, as well as in principle: all these things present questions yet to be solved.
