Within recent months, increased attention has been given the possibility of utilizing interstate compacts to cope with problems that transcend the boundary lines of given states. A Council of State Governments has been created to promote such interstate agreements, and several states have established commissions to facilitate coöperation with this council. Compacts have been advocated as solutions not only for the problem of criminal extradition, but also for such problems as the control of the extraction of natural resources (e.g., coal, oil, gas, water supplies, and water power) and the conservation of their supply, and the regulation of milk prices, of the conditions of labor, and of the production and distribution of the services of certain classes of public utilities.
