Show Movlm; a B rid go. The Norwich Bulletin says recently the Pennsylvania railroad wanted a big iron bridge, 258 feet long and weighing 25,000 tons, moved from its place ovet Mill Creek, near Lancaster, to a new Bite forty-live feet away. Master Carpenter Beard took the job. Ho had 100 men lo help him. lie made his preparation? leisurely, and, when the last train had passed over the bridge, with his hundred men and his trestles, rollers, jacks and cranes he set to work. In just lifty-eight minutes from the time the work began the bridge was iu its new place and u freight train of such size as o require two locomotives was passing over it Now tho ancients couldn't have done that in the same lime if they had had 10,000 men. What we know about iron and its uses and how lo work it is worth more to tho world than all the lost arts of all past ages combined. |
