233 POLICE POWER AND INTERSTATE COMMERCE., 233 and transactions is rendered ineffective. The police regulation that the State makes, may not conflict with any national regulation, and cannot interfere with the making of any ; it may be a perfectly reasonable provision to prevent disease and crime ; but as to inter- state commerce it may, under these decisions, be invalid. That such a consequence should follow from merely giving Congress " power ... to regulate commerce with foreign nations and among the several States," a provision made solely for the benefit of trade, is a result which it is hardly presumptuous to say the framers of the Constitution could never have intended. William R. Howland. Boston, November, 1890.
