I In- 1 water 1* always of tin- greatest im- portance in a power plant, and our readers will all be interested inthe purifying apparatus, ■ sectional view of which is shown in theaccompanying engraving. The operation oi tins purifier is designedto be entirely automatic and ti matter whether the intpuritie >i~t ..1 sabs in Bolutii r mechanically suspended matter, it is claimed thai the water issuing From the apparatus will be in perfectcondition for the boilers. The only attention required is the fillingf the storage receptacles once each day with the propei proportionsof lime and soda ash. I he purifier consists substantially of an auto-matically acting lime saturator, shown at the left as a conical tank,a soda chamber, which is a cylindrical pipe-like receptacle, and anautomatic filter in the main part of the apparatus, [he turn tlthoroughly mixes the lime with the incoming water, thewater being carried t 1 lu- base f the cone by an internal pipe and.

By the time it gets to the top, the lime water is perfectlyclarified, and leaves the saturator through a pipe which carries11 to the bottom of the large cylinder. This portion is known asthe reactimi chamber, and a concentrated solution from the sodachamber is forced into it through a small pipe. The difference in the !- by which the soda and lime arc dissolved is because of thegreater solubility of Soda, which makes it practicable to dissolvea sufficient quantity for _>j hours at one time in the small sodachamber and send it into the reaction chamber as required. Thesoda solution is forced out of the soda chamber by allowing waterlo flow in through a small regulating valve, the difference betweenthe specific gravity of the untreated water and the soda solutionliving sufficient to prevent the rapid mixing of the two. Much ingenuity has been shown in the
