In order to get the best work out of the locomotive thefiremen are obliged to fire lighter than they would without thisarch, which constitutes a strong feature of this device, becauseheavy firing is not only the cause of black smoke but alsoproduces dirty fires, clinkered grates and a consumption of.

RV. hollow fire brick arches on that road, the engravings pre-senting the arrangement employed in Atlantic type passengerlocomotives. The arch is built in two parts, the larger part being sup-ported on the water tubes in the usual way and the smallerarch over the door is supported on studs. The large archweighs approximately 929 lbs. and the smaller arch 310 blocks of each arch are made hollow, having oval pas-sage ways for air, receiving air from 2-ln. tubes passingthrough the water spaces. The air becomes heated in Itspassage through the arches and is discharged, through open-ings directing the current, downward towards the fire.
