Three hymns
A pastor explained to his congregation that the church was in need of some extra money, so he asked them to consider being more than generous. He offered that whoever gave the most would be able to pick three hymns.
After the offering plates were passed about the church, the pastor glanced down and noticed that someone had graciously offered a $1,000 bill. He was so excited that he immediately shared his joy with his congregation and said he'd like to personally thank the person who placed the money in the plate.
A very quiet, elderly, saintly lady in the back of the church shyly raised her hand. The pastor asked her to come to the front, so she slowly she made her way towards him.
The pastor told her how wonderful it was that she gave so much, and in thanks he asked her to pick out three hymns.
Her eyes brightened as she looked over the congregation. She pointed to the three most handsome men in the church and said, "I'll take him and him and him."

Asphalt pavementIn 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.] |
