“ If the cab which carries the passengers from the hotel to the ferry landing is engaged in interstate transportation, why is not the porter who carries the traveler's trunk from his room to the carriage also so engaged? If the cab service is interstate transportation, are the drivers of the cabs and the dealers who supply hay and grain for the horses also engaged in interstate commerce? ”

“ It is true that a passenger over the Pennsylvania Railroad to the city of New York does not, in one sense, fully complete his journey when he reaches the ferry landing on the New York side, but only when he is delivered at his temporary or permanent stopping place in the city. Looking at it from this standpoint, the company's cab service is simply one element in a continuous interstate transportation, and as such would be excluded from state, and be subject to national, control. The state may not tax for the privilege of doing an interstate commerce business. ”

“ Wherever a separation in fact exists between transportation service wholly within the state and that between the states, a like separation may be recognized between the control of the state and that of the nation. ”
