An older couple had a son, who...

An older couple had a son, who was still living with them.The parents were a little worried, as the son was still unableto decide about his career path, so they decided to do a smalltest.
They took a ten-dollar bill, a Bible, and a bottle of whiskey,and put them on the front hall table. Then they hid, hopinghe would think they weren't at home.
The father told the mother, "If he takes the money, he will bea businessman; if he takes the Bible, he will be a priest; butif he takes the bottle of whiskey, I'm afraid our son will bea drunkard."
So the parents took their place in the nearby closet and waitednervously, peeping through the keyhole they saw their sonarrive home.
He saw the note they had left, saying they'd be home later.Then, he took the 10-dollar bill, looked at it against thelight, and slid it in his pocket. After that, he took theBible, flicked through it, and took it also. Finally, hegrabbed the bottle, opened it, and took an appreciative whiffto be assured of the quality, then he left for his roomcarrying all the three items.
The father slapped his forehead, and said, "Damn! It's evenworse than I ever imagined..."
"What do you mean?" his wife inquired.
"He's gonna be a politician." the father replied.

Portland cement US patent

In 1871, U.S. patent No. 119,413 for the composition of portland cement was issued to David Oliver Saylor, of Allentown, Pa. In 1871, Saylor tried his hand at selecting and mixing different kinds of rock from his quarries to produce portland cement at the first US plant in Coplay, Pa. After initial difficulties, he succeeded with a mixture of magnesium clay with limestone clay. Samples shown at the 1876 Philadelphia Centennial Exhibition compared well with the best imported portland cements. In England, William Aspdin had patented "Portland cement," and coined the name (1852). The first recorded shipment of portland cement to the US was in 1868, when European manufacturers began shipping cement as ballast in tramp steamers at very low freight rates.[Image: Kilns at Coplay, Pa.]
