Little Johnny was caught swearing by his teacher.
"Johnny," she said, "you shouldn't use that kind of language. Where did you hear such talk, anyway?"
"My daddy said it," he responded.
"Well, that doesn't matter," explained the teacher. "You don't even know what it means."
"I do, too!" Little Johnny retorted. "It means the car won't start."

His railway engineering career began at age 17. By 1849, he was Engineer and Manager of the Edinburgh and Northern Railway. Realising the value of a bridge to replace ferries across the mile-wide Firth of Tay on the east Scottish coast, he spent 20 years promoting such a project before it was approved. The foundation stone was laid on 22 Jul 1871. The two-mile bridge of lattice girders on ironwork columns was opened 31 May 1878, but failed the next year. He died four months after the Court of Inquiry held him responsible for poor design against wind pressure.« |
