ported from one state to another and in the latter delivered to a large number of local distributing corporations. In all of these cases it was, of course, obviously impossible to earmark the gas when placed in the pipe line for delivery to any particular one of the local companies to which it. was to be delivered in the state of destination; nevertheless, in all of them the court held that the transaction constituted interstate commerce and was not subject to local regulation. In Eureka Pipe Line Company v. Hallanan, 257 U.S. 265, 42 S. Ct. 101, 66 L. ed. 227, all of the oil was produced in West Virginia and in that state placed in a pipe line extending into Ohio. The producers, however, reserved the right to divert quantities of oil from the pipe line while still in West Virginia and before it crossed the line into Ohio. Manifestly, it was impossible to earmark or segregate any quantity of oil when put in the pipe line in West Virginia and say it was to be delivered in Ohio.

It was impossible to earmark that part of the electricity which was to be transported in Massachusetts. But the court held that the transportation of that part which did reach Massachusetts was interstate coMmerce, not subject to local regulation. In Dahnke–Walker Milling Co. v. Bondurant, 257 U.S. 282, 42 S.

But again the court held that its purchase and transportation was interstate commerce, free from state interference.
"As heretofore remarked in discussing the original package doctrine, such considerations cannot apply to the interstate transportation and delivery of gas. From the very nature of the substance transported, the only
