The hissing sound grew louder. Suddenly the drill came hurtling out of the well, impelled by the tremendous pressure behind it, and shot through the heavy beams of the derrick as though they had been cardboard. Following the drill came a shower of sand and small stones. Those about the well were forced to race for shelter until the last of the debris had been blown out by the force of the escaping gas and the shower ceased.

Then the men came racing back, bringing with them the valve and clamps that were to be used to cap the well after the oil started to flow. As yet, nothing had come from the well but gas, but they knew the oil could not be far off. Under the terrific pressure of the outflowing gas, the heavy derrick began to crumble, and in a short time the whole upper part of it came apart and the stout timbers were whirled aloft and scattered far and wide like so many matchsticks.

The hissing grew louder, and a heavy rumbling sound vibrated along the pipe line, growing steadily louder and more menacing. In a few minutes more this sound had reached a huge crescendo, and then, with a shriek like that of an imprisoned demon liberated, the oil reached the surface and shot a hundred feet into the air in a huge, writhing black geyser that flared out at the top and deluged everything within a radius of hundreds of feet with raw glistening petroleum. As the oil fell, it rapidly collected into large pools, and started running off in every direction where there was a slight slope.

For a few seconds after the tremendous fountain started, Tom stood almost petrified by the magnitude of the spectacle. But the sight of the precious oil running to waste in such huge quantities galvanized Ned and Mr. Damon into action. Mr. Damon danced around, wild with excitement.

“Bless my oil drill!” he shouted. “We’ve struck it! We’ve struck it!”

“That wonderful drill of yours has done the trick!” cried Ned, wringing his friend’s hand.

“We’ve got the oil,” said Tom, who, though pale with excitement, still kept his head. “The thing to do now is to save it.”

The capping outfit with which they hoped to stem the tremendous force of the gusher was of a special design that Tom had worked out. It consisted of an extra heavy gate valve set in a cast steel framework, with heavy steel clamps for holding the entire assembly to the end of the well pipe. In addition to the actual valve and holding mechanism, Tom had contrived an ingenious screw mechanism with which to place the valve over the stream of oil.

“Get busy with that valve,” shouted Tom, his voice rising high above the din.

This was no easy task. In many similar wells, attempts had been made to imprison the oil with heavy timber boxes and framework, but the force of the oil stream is so great that these devices were usually shot up bodily into the air, and only came down in the form of kindling wood. Tom knew this, and in designing his capping mechanism had placed his reliance on steel as being the material best suited to withstand the strain.
