[Jack Simpson was a young collier working at the Vaughan pit in Lancashire. By careful attention to his work, and by private study of the science of mining, he had raised himself to the position of "viewer" or underground foreman. The mine having been found to be badly ventilated and dangerous, steps were being taken to put it right. But, as the events of the following story show, it was too late.]

One day, when Jack came up from his rounds at ten o'clock, to eat his breakfast and write up his journal of the state of the mine, he saw Mr. Brook (the owner of the mine) and the manager drive up to the pit mouth. Jack shrank back from the little window of the office where he was writing, and did not look out again until he knew that they had descended the mine; he did not wish to have any appearance of thrusting himself forward.

For another hour he wrote; and then the window of the office flew in pieces, the chairs danced, and the walls rocked, while a dull heavy roar, like distant thunder, burst upon his ears.

Jack leaped to his feet and rushed to the door. Black smoke was pouring up from the pit's mouth, sticks and pieces of wood and coal were falling in a shower in the yard; and Jack saw that his worst fears had been realized, and that a terrible explosion had taken place in the Vaughan pit.

For a moment he stood stunned. There were, he knew, over three hundred men and boys in the pit, and he turned faint and sick as the thought of their fate came across him. Then he ran towards the top of the shaft.

The bankman lay insensible at a distance of some yards from the pit, where he had been thrown by the force of the explosion. Two or three men came running up with white scared faces. The smoke had nearly ceased already; the damage was done, and a deadly stillness seemed to reign.

Jack ran into the engine-house. The engineman was leaning against a wall, scared and almost fainting.

"Are you hurt, John?"

"No!"

"Pull yourself round, man. The first thing is to see if the lift is all right. I see one of the cages is at bank, and the force of the explosion is in the upcast shaft. Just give a turn or two to the engine and see if the winding gear is all right. Slowly."
