"When the cylinder is changed, it is put in motion by a small steam-engine, and made to revolve slowly, first one way a few revolutions, and then the other, by which the clothes are thrown from side to side, in and out, and through the water. During this operation the steam is let in through a double-mouthed pipe--somewhat of this shape, X--which has one mouth in and one mouth out of water; the steam entering the water through the immersed end, and escaping through the other, by which means it is made to pass through the clothes, completely cleansing them in fifteen or twenty minutes. The steam is now cut off, and the hot water drawn through the waste pipe, and then cold water introduced, which rinses the articles in a few more turns of the cylinder. They are now suffered to drain until the operator is ready to take them out, when they are put into the drying-machine, which runs like a millstone, and its operation may be understood by supposing that millstone to be a shallow tub, with wire network sides, against which the clothes being placed, it is put in rapid motion; the air, passing in a strong current into the top and bottom of the tub, and out of the sides, carries all the moisture with it into the outside case, from whence it runs away. The length of time requisite to dry the clothes depends upon the rapidity of the revolving tub. If it should run 3,000 revolutions a minute, five to seven minutes would be quite sufficient. When there is not sufficient steam to run the dryer with that speed, it requires double that. In washing and drying, there is nothing to injure the fabric. Ladies' caps and laces are put up in netting bags, and are not rubbed by hand or machine to chafe or tear them in the least, but are cleansed most perfectly. "It can readily be imagined what a long line of wash-tubs would be required to wash 5,000 pieces a day, and what a big clothes-yard to dry them in; while here the work is done by four persons, who only occupy part of a basement-room, the other part being occupied by the mangle, and ironing and folding-tables. Adjoining are the airing-frames, which are hung with clothes, and then shoved into a room steam-pipe heated, when they are completely dried in a few minutes. "_Small Family Machines._--Almost the first thought, after witnessing the operation of this machine, was, can washing be done upon the same principle in small families? To our inquiries upon this point, we have received the following satisfactory information:--
