Report of the Master BlacksmithsConvention The seventeenth annual convention of the International Rail-road Master Blacksmiths Association, at Niagara Falls, wasopened August 17 by President Russell, who introduced Walsh, of Niagara Falls University, who made a shortaddress of welcome. Rev. F. S. Parker, Ph. D., of the St. PaulsMethodist Episcopal Church, was then introduced, who in behalfof the Mayor of Niagara Falls, N. Y., delivered the address of WBetr.

These tubes have returnbends at the end near the firebox flue sheet and the steam,returning, enters the superheated steam header. The super-heating is thus done by the passage of the steam againstand with the flow of gases from the firebox. On the design shown in Figure 1 there are ninty-sixpipes or forty-eight superheating elements, the combinedcapacity of which is sufficient to superheat all of the steamadmitted through the throttle and dry pipe. The steamafter passing through the superheater pipes and enteringthe superheated header is carried through the two steampipes at B to th
