decided ,in numerous cases, and in the case of Willamette Iron Bridge Co. v. Hatch, 125 U. S. 1, many of them are referred to by Mr. Justice Bradley in delivering the opinion. of the court. If, however, in exercising its right in regard to the regulation and control of commerce, private property must be taken, the Government is obliged to make compensation to the owner.
