The writer does not consider it practicable to use sodaash regularly for purifying boiler feed water. However,soda ash may be used for cleaning out the boiler by-dissolving 4 to 6 lbs. in clean water in a tub or tank,and pumping this into the boiler. The boiler shouldbe worked two or three hours, and then should be cutout and allowed to cool, after which it should be blownout, and man-holes and hand-holes removed, and theboiler thoroughly washed out with a hose.

DEVICE FOR GRAINING WOOD, BUFFALO knowledge) extensively used by street railways; therefore, we sub-mit an illustration of our outfit, thinking it may be of some interest. The hand roller, with its composition surface, is shown in the impression is made from the natural wood to the composition,and from that to the surface to be grained. The other articlesshown comprise a brass cylinder, bottom and bolts with which itis put together, forming a circular mould. The roller is placedin position inside the cylinder and the melted composition pouredin, making a continuous surface, so that no cracks or seams showin the graining. This outfit is entirely home-made, the roller beingwide enough to grain two stiles or rails at one time. It has provenitself in every way superior to the old and lengthy process of grain-ing by hand.
