Casino Money

A man spent a weekend gambling in Las Vegas casinos, and he won $100,000. He didn't want anyone to know about it, so whan he came back home, he immediately went out to the backyard of his house, dug a hole and planted the money in it.
The next morning he walked outside and found only an empty hole. He noticed footsteps leading from the hole to the house next door, which was owned by a deaf-mute. On the same street lived a professor who understood sign language and was a friend of the deaf man. Grabbing his pistol, the enraged man went to awaken the professor and dragged him to the deaf man's house. He screamed at the professor:
"You tell this guy that if he doesn't give me back my money I'll kill him!"
The professor conveyed the message to his friend, and his friend replied in sign language: "I hid it in my backyard, underneath the cherry tree."

The professor turned to the man with the gun and said: "He's not going to tell you. He said he'd rather die first."

Asphalt pavement

In 1870, Professor Edward J. de Smedt, was granted a U.S. patent for laying sheet asphalt pavement (U.S. Nos. 103,581 and -2). It was known as French asphalt pavement (where it was first laid in Paris in 1854). Mixing sand with natural asphalt is too stiff to work at suitable temperatures in the needed portions of about seven parts sand. Instead, he made a mix in ratio about 5 to 1, fluxed with certain petroleum oils and mineral particles, which was was easier to work with. On a graded road surface, a half-inch layer of hot sand is laid, topped with a one-inch layer of the hot asphalt and sand mix, and compacted with a hot roller. The process is repeated to build up a thicker road covering. On 29 Jul 1870, an experimental stretch of this type of asphalt pavement was laid in front of the City Hall, William Street, Newark, N.J.«[Image: Road crew laying asphalt for a new road in Florida, 1917.]
