The upper barrel or steam-drum is connectedwith the outer fire-box casing at the rear end and has alsothree connections with the main barrel ; it is 30J in. indiameter and 9 ft. 11} in. long. The usual water level isjust below the center-line of this upper barrel. It is claimed that this form of boiler, taking all its heatfrom the fire-box and tubes directly, will utilize a largerproportion of the heat than the ordinary locomotive type,and will not require any form of superheater or returntubes. The boiler shown was built for an old locomotive of theCrampton pattern—which still finds some favor in France—and was worked at a service pressure of 145 lbs. It hasbeen in use about 18 months, and the results obtainedhave been so good that the company is now building 12boilers of the same pattern for new locomotives. NOTES ON COMBUSTION. By C.
