One Sunday morning William burst into the living room and said, "Dad! Mom! I have some great news for you! I am getting married to the most beautiful girl in town. She lives a block away and her name is Susan.
After dinner, William's dad took him aside. "Son, I have to talk with you. Your mother and I have been married 30 years. She's a wonderful wife but she has never offered much excitement in the bedroom, so I used to fool around with women a lot. Susan is actually your half-sister, and I'm afraid you can't marry her."
William was heart-broken. After eight months he eventually started dating girls again. A year later he came home and very proudly announced, "Diane said yes! We're getting married in June."
Again his father insisted on another private conversation and broke the sad news. "Diane is your half-sister too, William. I'm awfully sorry about this."
William was furious! He finally decided to go to his mother with the news. "Dad has done so much harm. I guess I'm never going to get married," he complained. "Every time I fall in love, Dad tells me the girl is my half-sister."
His mother just shook her head. "Don't pay any attention to what he says, dear. He's not really your father."

Coal pipeline completed

In 1956, construction was completed on the first U.S. commercial coal pipeline. This coal slurry pipeline ran 108 miles from a coal mine (Georgetown Preparation Plant of the Hanna Coal Company, near Cadiz, Ohio) to a power station (Cleveland Illuminating Company, in Eastlake, Ohio). The 10¾- in diam. pipeline could transport over a million tons of coal per year. Mixed with an equal amount of water, it delivered 150 tons of coal per hour. It was placed in operation on 4 Jun 1957. After processing to remove the water, the coal slurry was ready for burning as fuel for the power plant. Slurry pipelines now exist transporting over twenty types of minerals, including iron-ore concentrate, copper ore, phosphate rock concentrate and mineral sands. Pipeline transportation costs less than by railroad.«
