A college of agriculture, therefore, is as much interested in the common schools as a college of arts and sciences is. It should be a part of a system, however informal that system may be, not an establishment isolated from other educational agencies. But even as a college it will reach more persons than it has ever reached in the past. In any self-sustaining commonwealth it is probable that one-third of the people must be intimately associated with the soil. These people need to be as well-trained as those who follow the mechanic trades or the professions. It is immensely difficult to put these agricultural subjects into teachable form and to reach the agricultural people in a way that will mean much to them, because agriculture is a compound of many wonderfully diverse trades in every conceivable kind of natural conditions. Nor can one institution in each large state or province hope eventually to reach all these people, any more than one institution can reach all those who would best be taught in terms of books. But there must be at least one institution that is well equipped for the very highest kind of effort in these fields; Congress long ago recognized this fact in the establishment of the land-grant colleges, and all persons who are informed on agricultural education also now recognize it. The agricultural colleges have been handicapped from the first for lack of funds. It is now coming to be recognized that the highest kind of effort in these colleges cannot be sustained on a farm that pays for itself nor by means that are copied from the customary college work in "humanities" and "science." If it is to be efficient, agricultural education of a university grade is probably more expensive to equip and maintain than any other kind of education.
