As was to be expected in view of the well-settled doctrine of the Supreme Court that the constitutional grant of power to regulate interstate commerce includes power of control over transportation of persons as well as property, it was held in Hoke v. United States, 227 U. S. 308, 57 L. Ed. 523, 33 Sup. Ct. 281, that the WHITE SLAVE TRAFFIC ACT of 1910 (36 Stat. 825), usually referred to as the MANN ACT, was constitutional. State legislation covering the same ground, it has been held, has been displaced. State v. Harper, 48 Mont. 456, 138 Pac. 495.
