The coal company shipped coal from its mines in Pennsylvania by means of its own private railway, river barges, and tugs to a point in Ohio where the coal was unloaded, washed, freed from impurities, and sorted into appropriate sizes. Thereafter it was delivered by the company to a common carrier in Ohio for transportation to points within the state to .fill orders often not received until after the coal left the mines. Held, the haul by the common carrier in Ohio is not subject to the jurisdiction of the Interstate Commerce Commission and is intrastate commerce which may be regulated as to rates by the Ohio Public Utilities Commission.
