Most of our readers have probably seen in the dailypn])ers some account of the accident to the Cunard steamer Uinbrin and its repair in mid-ocean ; but a brief accountwill not be out of place here. The main shaft broke in thethrust bearings where the body of the shaft is 25 in. indiameter, with collars 36^ iu. iu diameter and 3i in. thick,. break was between two of them, as is also sliown. Themethod of repair adopt.^d was to use two adjoining collarsas flanges of a coupling, connecting them by three 5-in. steelbolts. Ta do this grooves had to be cut in the two collarslarge enough to take the bolts ; the bolts had to be cut tothe pro|)er length ; t)ie nuts had to be cut down, as theywere too large to enter the space ; and bands had to be])laced around the shaft to hold tlie bolts in place. Thedifficulties attending this work at sea, with only the ham-mer and cold ihisel, and in the limited space around theshaft, can be imained. The new elevated railroad which runs along the waterfront of Liverpool a distance of about six miles, is to beoperated by electricity. The power station is near the mid-dle of the line, and contains three groups of dynamos, eachoperated by a engine. The current is carried bysteel bars placed between the rails on porcelain cars will
