This method of failure is not possible for thicknesses of butt straps required by these Rules and the computation need only be made for old boilers in which thin butt straps have been used. For this reason this method of failure will not be considered in other joints. Divide B, C, D, E, F,GoxH (whichever is the least) by A, and the quotient will 100 REPORT OF BOILER CODE COMMITTEE, be the efficiency of a butt and double
