A Scottish lad and lass were sitting together on a heathery hill in the Highlands. They had been silent for a while, then the lass said, "A penny for your thoughts."
The lad was a bit abashed, but he finally said, "Well, I was thinkin' how nice it would be if ye'd give me a wee bit of a kiss."
So she did so.
But he again lapsed into a pensive mood which lasted long enough for the lass to ask him, "What are ye thinkin' now?"
To which the lad replied: "Well, I was hopin' ye hadn't forgot the penny!"

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.]
