Neither can their fathers be depended upon to give a thorough education. Ministers at home would find it a great encroachment upon their time to spend several hours each day in instructing their own children; but they have _vastly_ more leisure to do so than the foreign missionary. To instruct a class of three or four requires the same apparatus, the same preparation in the teacher, and the same number of hours each day, as would be required for a class of thirty or forty. But should a missionary devote such an amount of time and means to his own family, it must be to the neglect of other labor. The most economical, and the most efficient course by far, evidently is, to collect together a sufficient number of missionaries' children to form a school, and devote a competent number of teachers entirely to that work. But even where such schools can be enjoyed, they must be attended with many risks and privations, and be only preparatory in their nature. Those scholars, who may need a thorough education, must be still under the necessity of visiting a Christian land. It is too of great, and perhaps indispensable importance, that youth who are trained for active life should see the industry, enterprise, and intelligence of a Christian land, and so far, at least, partake of its character and imbibe its spirit. Missionaries, then, must either suffer their children to grow up with a very limited education, or submit to the alternative sooner or later of sending them to a Christian land. But missionaries see the want of laborers in the great field of the world, and ardently desire that their children may be qualified to take part in the work. They choose therefore the present anguish of separation, bitter as it may be, that there may exist a reasonable prospect that their children, at some future day, may be eminently useful in the vineyard of the Lord. One other difficulty I must name, and that is, that missionaries' children, if kept on heathen ground, will have _no prospect of suitable employment when old enough to settle in life_. They will have no trades. To be merchants they will not have means. They will not be acquainted with agriculture, and in many countries will not be able to obtain land to cultivate. Some, who are fit for the work, may become preachers and teachers, but will not command the influence that they would if they were educated in a Christian land. Thus the prospect of suitable employment is very dark, and is a fact in the case of much weight.
