The "Torrent" washers of the larger class are supplied by Messrs.

boiled, columns of hot water were forced by the pressure f the steam formed at the bottom of the boiler through the holes provided at the top, so that a constant stream of nearly boiling water was playing into and at the top of the washer in the manner indicated in the illustration. The amelioration of the circumstances under which so many poor washerwomen have hitherto had to perform their hard work is a most desirable step; and the invention may be further appreciated as it gives to the working woman by a less laborious task the means of competing, at a smaller cost, with the expensive machines of steam power aundries. The inner vessel, or washer, can be made to fit any existing boiler, whether fixed or portable, by taking the diameter and depth of the copper. Some of large sizes, from forty to fifty gallons, have been made and are, we to fit into the same handles, blunt hook and crotchet understand, in use in laundries and baths, and competing (jointed), frænum scissors, and female catheter.
