“They went up the river on the right shore. The whole road, an ugly dirt road at that, was covered with crude oil. It seemed to break through cracks and holes in the ground. There were even pools and ponds of oil. It came mostly through leaks in the pipes and from overflowing tanks which were lined up on the hills along the shore. Brooks of crude oil ran down like water into the river. Nobody seemed to care about the loss of these thousands and thousands of barrels of oil, which soaked the soil and polluted the river. So rich in oil was this part of the world then that the company managers and directors seemed not to mind when a well which brought in twenty thousand barrels a day caught fire and burned down to its last drop. Who would care about three or four hundred thousand barrels of oil running away ever week and being lost owing to busted pump lines, to filling tanks carelessly, or to not notifying the pumpman that while he has been pumping for days, sections of the pipe lines have been taken out, to be replaced by new ones. The more oil is lost, the higher the price. Three cheers, then, for broken pipes and drunken pumpmen and tank-attendants!”
