"(d) By later cases the power gas been extended to embrace contracts as to things in commerce, as correspondence by telegraph, etc. These telegraphs were long since invemted, but as they were new means of commerce of persons and things, the power embraces commerce through those means as it had done through the old and superceded means. The power is not changed by the increase of its domain by reasons of the advance of scientific investigation.1 In regulating commerce, therefore, Congress regulates traffic in things, vehicles of transport, and things !in transitu!, but not the things themselves. Before and after the !transitus! they are beyond this power of regulation. The production and use of things in the !terminus a quo! and the !terminus ad quem! are not subjects of the commercial power, but of the law of the State or country from which and to which they are transported.2
