The writer desires first of all to confess that unfortunately no new revelations on the theory of combination of enterprises have come to him in the preparation of this paper. Merely to review the contributions of other workers in this field may seem like threshing over old straw. This is especially true since the theories bearing on this subject have been admirably stated by a number of writers in recent farm management literature.' However, a review of the farm management research work to date, especially as it relates to the problem of combining enterprises on individual farms, leads to the conclusion that there are some phases which need to be given greater emphasis in the future if the results are to show real progress in the field. First of all we need to close the gap between the broad economic principles, which form the foundation for our approach to the farm management problem, and to the analysis of specific problems on individual farms. In other words, we should try to place the problem of the combination of enterprises on the individual farm in its proper setting with respect to the general economic principles which have a bearing on that problem. This may mean a preliminary qualitative analysis and later a refinement, testing, or application of such principles; or all of these steps in some instances, but the important point is that the analysis is not complete before the nature of the connection of the principles to the specific problem is decided.3 Secondly, we need closer analysis of the situation on actual individual farms if our conclusions are to have as much validity as we would like to claim for them. This involves more detailed information on the nature of each individual enterprise in the business; but also, and more important perhaps, a greater realization of the complexity and the essential unity of the organism called a farm business.
