Besides the break in the strap, theconnecting rod was bent. The piston was cracked in five places. Thepiston rod at the water end was broken off at the cross-head, andthe cross-head itself was broken. The stuffing box gland at the waterend was broken and the parallel rods, which connected the steam andwater pistons, were badly bent and twisted. On account of the large. iga5.] THE LOCOMOTIVE. 131 casting which had to be replaced, repairs were expected to requireconsiderable time. The engine was built in 1907. The property loss in the accident was covered by a HartfordSteam Boiler policy. The Efficiency of Reinforced Tube Ligaments By G. H. Stickney, Supt, Boiler Department, and B. C. Cruickshanks, Editor. THE strongest part of a steam boiler is the original solid plate,and whenever this plate is cut, no matter what well designed jointis substituted, the boiler is weakened. It is readily apparent,therefore, that in the cross drum type of boiler, where rows of tubesrunning the full length of the drum must enter the drum, and the ef-ficiency is to be increased, some reinforcement must be provided toreplace the metal cut out to accommodate these tubes. For instance,if we have a four inch tube (4^2 inch hole) entering the drum everyseven inches of its length, there would be but 7— 4^2 = 23%2 inchesof metal left intact between the tubes
