Nearly two years ago the Iowa Agricultural Experiment station set out to answer a demand from scores of communities for accurate information on when, where, and how creamery associations might be organized with profit and how a satisfactory creamery should be bulit. Since that time, the station has assisted in the organization of different creamery companies and aided in the construction of eight different creamery buildings. The companies represent every type, from individual ownership to regularly incorporated associations and the buildings are of various types and sizes, ranging in cost from less than $2,000 to more than $6,000. Much valuable detailed information was secured which is now published so that it may be of service to other communities which face the question of organizing a creamery association and erecting a creamery building.
