405 mixed with air in the right proportion to produce perfect combustion, which i~ indicated by a non-luminous flame. The power developed by the explosion of acetylene completely burned in the cylinder is said to be much greater than that obtainable with water-gas.

ELECTRICITY IN PAPER-MAKING.

The Electrical World reports that the Cumberland Mills, near Portland, Me., are operated by power electrically transmitted from a waterfall four miles distant.

The generating plant consists of two 300 horse-power dynamos coupled to 48-inch Victor vertical turbine. The alternating current system is used, the pressure being raised by transformers from I,IOO volts at the generators to 8,ooo volts at the mills, where it is again reduced to 40o volts for Supplying the motors.

The efficiency of the plant is found to be about 76 per cent.', from the brake horse-power of the turbines to that of the motors. A marked saving is said to be effeeted in comparison with steam-power.
