In my Sunday school class the focus was marriage or divorce, "The rapidly increasing divorce rate," remarked one member of the group, "indicates that America is indeed becoming the land of the free."
"Yes," replied the prosaic friend, "but the continued marriage rate suggests that America is still the home of the brave."
Railroad safetyIn 1870, Thomas S. Hall of Stamford, Conn., received a patent for the first automatic electric block railroad signal system in the U.S. (No. 103,875). When a train entered a block of track, Hall's electromagnetic device automatically set a signal when the locomotive struck a lever fastened to the rail. The signal was set to danger until the train cleared the block. After Hall invented the device in 1867, it was tried out on the New York and Harlem Railroad. |
