killed people. Then the peasants ran for hooks and began to pull out the elder and the woman. The elder’s mother and wife cried at the well, and others tried to quiet them; in the meantime the peasants put down the hooks and tried to get out the dead people. Twice they got the elder halfway up by his clothes; but he was heavy, and his clothes tore and he fell down. Finally they stuck two hooks into him and pulled him out. Then they pulled out the cow-tender. Both were dead and did not revive.
Then, when they examined the well, they found that indeed there was bad air down in the well.
This air is so heavy that neither man nor any animal can live in it. They let down a cat into the well, and the moment she reached the place where the bad air was, she died. Not only can no animal live there, even no candle will burn in it. They let down a candle, and the moment it reached that spot, it went out.
There are places underground where that air gathers, and when a person gets into one of those places, he dies at once. For this purpose they have lamps in the mines, and before a man goes down to such a place, they let down the lamp. If it goes out, no man can go there; then they let down fresh air until the lamp will burn.
Near the city of Naples there is one such cave. There is always about three feet of bad air in it on the ground, but above it the air is good. A man can walk through the cave, and nothing will happen to him, but a dog will die the moment it enters.
Where does this bad air come from? It is made of the same good air that we breathe. If you gather a lot of people in one place, and close all the doors and windows, so that no fresh air can get in, you will get the same kind of an air as in the well, and people will die.
One hundred years ago, during a war, the Hindus captured 146 Englishmen and shut them up in a cave underground, where the air
