“ As respects the West Virginia gas, we are of opinion, in view of its continuous transportation from the places of production in one state to those of consumption in the other, and its prompt delivery to purchasers when it reaches the intended destinations, that it must be held to be in interstate commerce throughout these transactions. ”

“ The People's Company is a public service corporation created under the laws of Pennsylvania, and engaged in producing, purchasing, transporting by pipe line, and selling natural gas. It purchases about two-thirds of the gas which it transports and sells from a producing company in West Virginia having pipe lines leading from wells in that state to the boundary between the two states, and it produces the other one-third from its own wells in the southwestern counties of Pennsylvania. ”

“ Prior decisions leave no room for discussion on this point and show that the passing of custody and title at the state boundary without arresting the movement to the destinations intended are minor details which do not affect the essential nature of the business. ”
