Getting John to Quit

John was a loyal choir member, but he could not carry a tune. To make things worse, he sang loud and made others sing off key. Without success, the choir director had tried to discourage John from participating in the choir. The choir director asked the pastor's help in getting John out of the choir. The pastor agreed to try. The pastor tried to find tasks and responsibilities that would interfere with John's attendance at choir rehearsal or keep him out of the choir loft on Sunday morning. John, however, would not accept any of the tasks or responsibilities, stating that he would not shirk his duties as a loyal choir member. Finally, the choir director gave the pastor an ultimatum, "Either you find a way to get John out of the choir or I will resign as choir director."So, with much uneasiness, the pastor called upon John at home one evening and said, "John, I must ask you to drop out of the choir." John was shocked and asked, "Why would you ask such a thing? We need all the singers we can get." The pastor replied, "Well, John, people are complaining about your singing." "How many?" was John's response. Not wanting to be too harsh and admit that nearly everyone in the congregation had been complaining, the pastor said, "I've received more than a dozen complaints." "I'm sorry, pastor, that's not enough. I've heard a lot more complaints about your preaching and you haven't quit yet."-

Steam locomotive

In 1829, the first steam locomotive for railroad use in the U.S., the Stourbridge Lion, made its first run in America. It travelled at 10 m.p.h. on the wooden tracks faced with wrought iron that already existed as a gravity railway, used to carry coal from mines at Carbondale to the canal terminus at Honesdale, Pennsylvania. The 7-ton engine was built by Foster, Rastrick & Co., of Stourbridge, England for the Hudson Railroad Company to specifications drawn up by John Bloomfield Jervis, chief engineer for the Delaware and Hudson Canal project. However, after the trials, it was deemed to be too heavy for continued use hauling loads of coal on those tracks.«[Image: replica of the Stourbridge Lion built at the Delaware and Hudson Railroad's Colonie Shops, NY, in 1933]
