Little Zachary was doing poorl...

Little Zachary was doing poorly in math. His parents, after exhausting all other incentives, finally decided to enroll him in the local Catholic School. After the first day, Little Zachary came home with a very serious look on his face. He went straight to his room and started studying. This continued for some time. His mother was baffled as to why he had become so dedicated.
Finally, Little Zachary brought home his report card. He quietly laid it on the table and went to his room to study. With great trepidation, his mother looked at it and, to her surprise, Little Zachary go an "A" in math. She asked, "Son, what was it? Was it the nuns, the books, the discipline, the uniforms?"
Little Zachary said, "No!"
"What was it?" she asked.
Little Zachary looked at her and said, "Well, on the first day of school, when I saw that guy nailed to the Plus Sign, I knew they weren't fooling around."

Steam shovel

In 1839, Mr. William Smith Otis, civil engineer of Philadelphia, Penn., was issued a U.S. patent for the steam shovel (No. 1,089) for excavating and removing earth from railroads or canals. The patent drawing showed the crane mounted on a carriage or railroad car. A load of earth could be taken up by the scraper, raised by the crane and turned to be dumped, such as in railcars, and released. The patent described how a steam engine of a kind already in ordinary use, was installed with a power control mechanism for the crane, and a system of pulleys to move its arms and bucket. It could move about 380 cubic metres of earth a day, with its 1.1 cubic metre capacity shovel and 180° slewing wooden jib. It was first used on the Western Railroad in Mass.[Image: Steam shovel built by John Souther in his Globe Locomotive Works in South Boston, Mass. shown behind railcars it is loading with gravel (1857).]
