A DESERT LIGHT.--In Arizona there is an important well which stands in the desert where its presence would not readily be known, but for the fact that a light now swings from a tall cotton-wood pole so as to light travelers who are within several miles of it in the night. Before the lantern used to be hung there many people died when they might have reached its waters if they had only known how near and in which direction the well really was. Some have died horrible deaths of thirst when only a short distance from its refreshing waters. In order to pass that point travelers have to carry large loads of water to quench their thirst until they reach this well. The number of gallons a company has means either life or death to all. Some time ago a German boy staggered up to the tanks shortly after dark. He had lain down expecting to die with thirst in despair of getting to water, when he saw the light of the cabin of the keeper of the well. So Joe Drew keeps his lantern up at night that others may see the signal from afar and come without delay to the waters. MINER'S LUCK.--One of the most profitable mines in South America is the Penny mine in Bolivia. Penny was a run-away Scotchman from a man-o'-war who had nothing and hoped for nothing but to keep away from service on the sea. He did odd jobs about the country for awhile and was brought low with fever. He was faithfully nursed through the disease by a native woman who could not speak a word of English. Out of gratitude he married her and treated her well. She rewarded him by taking him into the mountains and showing him an old Spanish mine that had been hidden for years. He began working it and became a millionaire. With a fellow-workman by the name of Mackenzie he brought the mine into a good state of productiveness, and then left for the old country. Mackenzie was made superintendent of his mine, and Mackenzie's son went with Mr. and Mrs. Penny to Scotland. He arrayed his Indian wife in the most costly attire, and made his visit to Scotland memorable by his many acts of generosity. He adopted a nephew and insisted that both young men should take his name and become his heirs. He suddenly died and left his wealth all to his wife, with directions that the two sons should be amply provided for. Complications followed, and the Indian mother died under suspicious circumstances, while the boys contended for possession of the mines. With all the good fortune and excellent intentions of the father the two boys proved to be bad Pennies. They sold out their interests for $500,000 each and are now killing themselves with drink.
