When the subject of superheaters forlocomotives was under discussion at theMaster Mechanics convention, .Xngus.Sincair said: to result from the use of these super-heaters; it seemed that a little extra ex-pense made it possible to utilize a greatamount of heat that otherwise wouldhave passed through the stack. On or-dinary reasoning, it seemed that greateconomy would result from the use ofthe superheater; but somehow theygradually went out of use, and I thinkthey are very little used to-day. In the case of the steamboats it waslike what sometimes happens with loco-motives. If everything went on allright, economy would result, but if thesuperheater would give out, and some-thing was wrong and a few hours werelost at sea on a voyage, the expense in-
