CHINESE FIRE-WELLS.
A French traveller has given a vivid description of the famous fire-wells of China. He says that where the air escapes it is very inflammable, and if a match is presented at the mouth of the shaft, the gas explodes like gunpowder, and forms a great column of fire twenty or thirty feet high.
He says the largest fire-wells are situated in the mountains about one hundred miles from Wutung. They are in a valley, where pits were sunk in the hope of finding salt water. The water was not found; but suddenly a column of gas rushed out, bringing masses of earth and stones. The noise was terrific, and was heard a long distance. The mouth of the pit was surrounded by a stone wall six or seven feet high. As soon as the fire reached the mouth of the well it caused a terrible explosion, something like an earthquake. The flame was several feet high, and the force was sufficient to throw down some of the stones composing the wall. Several men carried a large flat stone to the pit, and placed it over the mouth. It was immediately thrown into the air, and some of the men were badly injured.
Neither water, stone, nor earth would extinguish the fire. After two weeks of hard work a quantity of water was brought over the mountains from a small river, and a lake was formed. The water being suddenly turned into the well, the fire was extinguished.
In some mines it is the custom, where the accumulation of fire-damp is gradual, to light it every night, so that the works may be always accessible in the daytime. The man whose duty it is to light the fire-damp wraps himself in a thick blanket, covering his face with a mask, and with his head enveloped in a hood like a monk’s. The fire-damp is lighter than the atmosphere, and always rises to the upper part of the level. Consequently the man crawls upon the ground in order to put himself in the best position for breathing. In one hand he holds a long stick, with a lighted candle fixed at the end.
He pushes the stick to its full length, and creeps along, firing the gas; and as soon as he has fired it he changes his position, and walks upright, since the fire-damp is always followed by the choke-damp, which is heavier than air, and sinks to the bottom.
THE PENITENT.
In the French mine this man is called a penitent, on account of his dress resembling that worn by some of the orders of the Catholic church. His name sometimes would seem to be a cruel jest, as he is liable to be blown away by an explosion, and never return alive. In other mines he is called the cannoneer, and when the fire-damp kills him he is said to have died at his post.
