Paper-Eating Dog

A minister delivered a sermon in 10 minutes one Sunday morning, which was about half the usual length of his sermons. He explained, "I regret to inform you that my dog, who is very fond of eating paper, ate that portion of my sermon which I was unable to deliver this morning."After the service, a visitor from another church shook hands with the preacher and said, "Reverend, if that dog of yours has any pups, I want to give one to my minister."

Robert Livingston Stevens

Born 18 Oct 1787; died 20 Apr 1856 at age 68.U.S. engineer and ship designer who invented the inverted-T railroad rail and the railroad spike. He tested the first steamboat to use screw propellers, invented and built by his father, John Stevens. Robert designed the first concave waterlines on a steamboat (1808), the first supporting iron rods for projecting guard beams on steamboats (1815), the first skeleton walking beams for ferries (1822), the spring pile ferry slip (1822), the placement of boilers on guards outside the paddle wheels of ferries (1822), the hog frame or truss for stiffening ferry boats longitudinally (1827), spring steel bearings of paddle wheel shafts (1828), improved packing for pistons (1840), and was first to successfully burn anthracite coal in a cupola furnace (1818). He found that rails laid on wooden ties, with crushed stone or gravel beneath, provided a roadbed superior to any known before. His rail and roadbed came into universal use in the United States. He also added the pilot, or cowcatcher, to the locomotive and increased the number of drive wheels to eight for better traction.
