A Paint Spraying Machine.

Paint spraying machines are now very extensively used. Our illustration depicts an English portable, s^lf-contamed machine, composed of heavy galvanised iron. The pumping apparatus is made of solid brass, which will not corrode from the use of any liquids. It also has an agitator, which keeps the liquid in motion while working the machine. One man can pump and spray at the same time, and ioo to 125 pounds pr- ssure can be easily carried. It can be used for whitewashing, painting, spraying

of fruit trees, and many other disinfecting works. The tank will hold seven gallons of liquid, and the capacity of the machine is equal to the work of five men with brushes in the same time.

Titanic acid (the oxide of titanium) was claimed, at a recent meeting of a society of dyers in Manchester, to possess remarkable fire-proofing qualities. Some pieces of flannelette treated with the acid refused to burst into flame when applied to a match. The incipient fire in the material merely smouldered and went out. If, as is said, all inflammable textiles can thus be rendered fireproof, and neither dyeing boiling, or washing will remove the acid, the discovery, when commercially availed of, should avert many fatalities of a regrettable character, only too frequent in. the past. Metal can be fastened to wood without nails or screws by a mixture of best joiner's glue and glycerine. The metal surface should be first roughened by the use of dilute sulphuric acid.
