One Sunday morning George burs...

One Sunday morning George 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, George's dad took him aside, "Son, I have to talk with you. Look at your mother, George. She and I have been married 30 years, she's a wonderful wife and mother, 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." George was brokenhearted.
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, George.
"I'm awfully sorry about this." George was livid! He finally decided to go to his mother with the news his father had shared.
"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."
"Hee hee," his mother chuckled, shaking her head, "Don't pay any attention to what he says. He's not really your father."

Mont Cenis Tunnel joined

In 1870, the mid-point rock wall was removed and joined the two bores completing the Mont Cenis Tunnel through the Alps. Workers who had been digging towards each other from both sides of the mountain met and shook hands. The previous day, a hole had been drilled through the remaining 4 feet of rock between them, and the workers from the two bores could hear each other. The two bores met with an accuracy of within 2 feet vertically and about 18 inches horizontally. By the next year, twin railroad tracks had been laid, and the Mont Cenis Tunnel was opened on 17 Sep 1871. Digging had started in 1857, tediously slowly by hand boring, until French engineer Germain Sommeiller, introduced industrial-scale pneumatic drills. Train service began 16 Oct 1871.*«[Image top: Mont Cenis Tunnel entrance arch; bottom: Sommeiller Boring Machines.]
