It it should be required to place a hanger between flooring beams, the floor to which it is attached should be strengthened with a generous piece of plank. For securing hangers, lag-screws are superior to bolts with nuts, where there is sufficient thickness of wood. A wooden straight -edge reaching from one bearing to another, is better for leveling hangers and boxes than a twine, which will sag more or less. Some use short cylinders Of iron turned to fit the box, and having a central hole drilled longitudinally through them. This is an excellent plan, as the eye may sight through, or a string be passed through to determine the level. Where holes are to be bored through the floor close to a wall, post, or other vertical obstruction, a handy tool, similar to that shown in the cut, comes into play. It is easily forged, and need not be finished with the elegance of contour shown. A is one of the yokes, and B the cross; they are seen united at C. The shank of one yoke has a tapering square hole to receive a bit or auger, and the other is a tapering square shank to lit a stock of the bit brace. The device is "a universal joint, " and can be readily Worked at an angle of 450 .

Hot Bearing AlaRm, -A cylindrical box, A, is provided with a perforated bottom, B, and placed directly over the journal. The box is filled with a prepared grease which melts at a certain temperature, to which it must be raised by the shaft becoming hot. As the compound liquifies and escapes through the perforations, a disk, C, which rests thereon, descends, thereby tilting the lever, D, and so making contact, between the plates, E and F. The latter are connected by an electric circuit with a bell which sounds when the current is established. The pipe, G, serves for the ordinary lubrication of the journal. It is suggested that this device might be profitably used upon journals not readily accessible.
