"I like to see a boy not ashamed to do dirty work, if that is what his duty calls him to do," said Mrs. Halford. "He comes out all the brighter and cleaner by contrast when the dirt is washed off."
If Derrick's right ear did not burn and tingle with all this praise, it ought to have done so; but perhaps he was too busy telling the exciting news of the day at home to notice it.
He did not walk past the Jones's house, nor hesitate before ringing the door-bell on this occasion, as he had the evening before, but stepped up to it with all the boldness of one who was about to meet and greet old acquaintances. Besides, his mind was too full of the sad fate that had befallen his mule to admit of more than the briefest consideration of personal feelings.
At the supper-table the conversation was wholly of mines, collieries, and the perils of miners' lives, in regard to which Mr. Jones related a number of interesting incidents.
"How wonderful it is!" said Miss Nellie, who had listened to all this with eager attention. "Who first discovered coal, anyway, Uncle Warren? and how did people find out that it would burn?"
"If you mean who discovered anthracite coal, I believe the credit is generally given to a man named Philip Gunter, who lived in a cabin on the side of a mountain not far from where we are now sitting. He was a hunter; and the story goes that one day in the year 1791 he had been out hunting for many hours, without securing any game, which made him feel very badly, for when he left home that morning there was no food in the house. Towards night he was returning, greatly depressed in spirits, and paying so little heed to his footsteps that he stumbled and fell over some obstacle. Stooping to see what it was, he found a black stone, different from any he had ever before noticed. He had, however, heard of stone coal, and thought perhaps this might be a lump of that substance. Having nothing else to carry, he decided to take it home as a curiosity. Soon afterwards he gave it to a friend, who sent it to Philadelphia, where it was pronounced to be genuine coal. A few gentlemen became interested in this discovery, and formed themselves in the 'Lehigh Coal-mine Company.' A mine was opened, and four laborers were employed to work it; but as there was no way of getting the coal they mined to market they were soon discharged, and the project was abandoned for the time being.
"Nothing further was done until 1817, when Colonel George Shoemaker, of Pottsville, took four wagon-loads of anthracite coal to Philadelphia, and tried to sell it there. People laughed at him for telling them that those black stones would burn; but he guaranteed that they would. Upon this a number of persons bought small quantities on trial; but all their efforts failed to set it on fire. Then they became very angry, and tried to have Colonel Shoemaker thrown into prison for cheating them. He fled from the city, pursued by officers who held warrants for his arrest. Finally he managed to elude them, and reached his home, thoroughly disgusted with coal, and ready to swear that he would have nothing more to do with it.
"In the mean time a lot of the black stones had been purchased for trial by the Fairmount Nail-works. It was placed in one of the furnaces, and the proprietor spent a whole morning with his men in trying to make the stuff burn. They were unsuccessful, and finally, completely disheartened by their failure, they shut the furnace door and went off to dinner, uttering loud threats against the man who had sold them such worthless trash. Upon their return to the works they were filled with amazement, for the furnace door was red hot, and a fire of the most intense heat was roaring and blazing behind it. Since that time there has been no difficulty in selling anthracite coal nor in making it burn. Now the production of coal in this country has reached such enormous proportions that its annual value is equal to that of all the gold, silver, and iron mined in the United States during the year."
Just here Mr. Jones was interrupted by the arrival of the report of Harry Mule's condition. It was very brief, and pronounced the animal to be so badly injured, and his chances of recovery so slight, that it would cost more to attempt to cure him than he was worth.
"Now what am I to do about him?" asked Mr. Jones.
