In order to purify the air in a coal mine like the one at Avondale, it is necessary to force out the foul vapor; and, in addition to the fans used, it is customary to build fires at the bottom of the shaft, in order to get rid of the “damp.” When the mine is in operation these fires are never allowed to go out. When work is resumed after a suspension, care is necessary in kindling the fire. As before stated, there had been a strike among the miners, and work entirely suspended at the mine. The fire at the bottom of the shaft had gone out, and when work was resumed, it had to be rekindled. When it was relighted, the blaze flashed up before any coal had been placed upon the wood. It was supposed that the wooden lining of the shaft caught from the blaze, although there were several feet of brick-work at the bottom. With a strong current of air, the flame immediately rushed up into the engine-room, setting fire to everything combustible in its way. The appearance of the fire, to one who could forget the peril of the men in the mine, was grand in the extreme. When it was at its height, the flames rose a hundred feet and higher. They were swayed by the wind, and could be seen now at an angle of forty-five degrees, and then almost perpendicular, while dense clouds of smoke rose and filled the air. As the day drew to its close, the excitement of the scene increased. For many miles up and down the beautiful valley the glare of a thousand lights was visible. The vast quantities of coal that had caught fire in the breaker were covered with sheets of colored flame, and occasional flashes added to the glare that lighted up the valley.

A TERRIBLE SCENE.

While preparations for entering the mine were in progress, hundreds of eyes were in tears, and the air was filled with the shrieks and sobs of those whose relatives and friends were below. As soon as the firemen could get to work, they began operations by sending a stream of water down the burning shaft in order to extinguish the fire; but for a long time the flames seemed to defy their efforts, and it soon became evident that the water supply was a very meagre one. It was also found very difficult for the firemen to work, as the location was upon a steep hill-side. In a few hours after the outbreak the shaft was completely choked up, for a distance of forty feet, with rubbish. Most of the day was taken up in endeavoring to clear away the débris, so that the engines might be used.

While all this preparatory work was going on, the throng of miners and workmen increased, and the hill was crowded with people. Meetings were organized for various purposes, and at one of them fifty experienced men were selected to enter the mine as soon as it was practicable to go there. Among these men three were owners and superintendents of adjacent mines; they volunteered their services, and were ready to die, if necessary, in the effort to rescue their fellow-miners, and subsequently some of them barely escaped death.

THE DOG AND LAMP.

About half past five P. M., most of the timber and rubbish had been cleared away, and a dog and lamp were sent down the shaft to test the condition of the air. The cage was lowered as far as possible. When it came back the dog was alive, and the lamp was still burning. At half past six a man went down in a bucket, and returned in about seven minutes. He was able to breathe, but could not get beyond the obstructions. Soon after his return two men went down with tools, and, after clearing away the obstructions, they returned safely. While they were down they went through a gangway sixty or seventy yards, and came upon three dead mules lying near the stables. Then they came to a door which led into the mine, and, although they shouted and struck upon it repeatedly, they obtained no reply, and there were no indications that any of the imprisoned men were alive. Clouds of sulphurous gas were pouring out of the mine; so the men retreated.

Again another party descended to make explorations, but they were obliged to retreat, owing to the foul air and “black damp,” and by the time they reached the top they were partially overcome. An engine was then rigged for the purpose of driving a fan at the mouth of the shaft, so as to force in air through a canvas hose, as the “choke damp” was found to be three or four feet deep at the bottom of the mine. One gang of men from the Scranton mines also suggested that an attempt should be made to drive a gangway from a neighboring mine into the Avondale; but it was found that it would take too long to cut through the solid rock, and the suggestion was not carried out.
