An ingenious device is in use to show when a bolt has small hole is drilled into the head, extending a little waybeyond the plate, and as experience shows that the fracturenearly always occurs next to the outside plate, that is the endtaken for the bored out head: when the bolt is broken the rushof steam through the small hole shows the danger withoutcausing serious disturbance. Even where the best of iron is used for stay bolts they shouldnever bo exposed to more than cith or luth their breakingstrength. The stays should be well fitted, and each one carefully tight-ened, and, as far as possible each stay in a group should havethe same regular strain upon it—if the pull all should comeon one the whole are liable to give way.
