A step-ladder is an almost indispensable article to persons who are moving into a new house. Not only do the domestics find it extremely convenient when they undertake to wash the windows, to remove the dust from the door and window-frames, and to perform sundry other household duties, but the lord of the castle will require it when he hangs his pictures, when he fixes the curtains and when he yields to his wife's entreaty for a hanging shelf or two in the cellar. I would, however, warn my fellow-countrymen against the contrivance which is offered to them under the name of the "Patent Combination Step-ladder." I purchased one in the city just before we moved, because the dealer showed me how, by the simple operation of a set of springs, the ladder could be transformed into an ironing-table, and from that into a comfortable settee for the kitchen, and finally back again into a step-ladder, just as the owner desired. It seemed like getting the full worth of the money expended to obtain a trio of such useful articles for a single price, and the temptation to purchase was simply irresistible. But the knowledge gained by a practical experience of the operation of the machine enables me to affirm that there is no genuine economical advantage in the use of this ingenious article. [Illustration] Upon the day of its arrival, the servant-girl mounted the ladder for the purpose of removing the globes from the chandelier in the parlor, and while she was engaged in the work the weight of her body unexpectedly put the springs in motion, and the machine was suddenly converted into an ironing-table, while the maid-servant was prostrated upon the floor with a sprained ankle and amid the fragments of two shattered globes. Then we decided that the apparatus should be used exclusively as an ironing-table, and to this purpose it would probably have been devoted permanently if it had suited. On the following Tuesday, however, while half a dozen shirts were lying upon it ready to be ironed, some one knocked against it accidentally. It gave two or three ominous preliminary jerks, ground two shirts into rags, hurled the flat-iron out into the yard, and after a few convulsive movements of the springs, settled into repose in the shape of a step-ladder. It became evident then that it could be used with greatest safety as a settee, and it was placed in the kitchen in that shape. For a few days it gave much satisfaction. But one night when the servant had company the bench was perhaps overloaded, for it had another and most alarming paroxysm; there was a trembling of the legs, a violent agitation of the back, then a tremendous jump, and one of the visitors was hurled against the range, while the machine turned several somersaults, jammed itself halfway through the window-sash, and appeared once more in the similitude of an ironing-table.
