In these three types of successful farmers religion is an essential factor. No history can be written of the Mormons, of the "Pennsylvania Dutch" or of the Scotch Presbyterian without recording their religious devotion, their obedience to leaders, to customs and to creed. One cannot live among them without feeling the peculiar religious atmosphere which belongs to each of them. They are admirable or obnoxious, according as one likes or dislikes this religious character of theirs, but it pervades the whole life of the community. If it be true that there is no type of farmer--except the scientific farmer of the past few years--who has succeeded as these three types have succeeded, and there is no country community so tenacious as their communities are, and if it be true that these farmers more uniformly than other farmers are religiously organized, then it follows that there is an essential relation so far as American agriculture goes, between successful and permanent agriculture and a religious life. The country church becomes the expression of a permanent and abiding rural prosperity. Agriculture is shown by its very nature to require a religious motive. An element of piety appears to be necessary in the makeup of the successful farmer. In these three types of successful farmer there appears another principle which is common to them all. They are not only organized for farming, but they are organized as a mutual prosperity association, based on their consciousness of kind. Prof. Gillin has called attention to the habit of the Dunkers in Iowa, who are of the Pennsylvania German sects, by which they extend their farming communities.
