The stomach should be emptied always after taking any of these antidotes, by a warm water emetic. In case of bleeding at the lungs, or stomach, or throat, give a tea-spoonful of dry salt, and repeat it often. For bleeding at the nose, put ice, or pour cold water on the back of the neck, keeping the head elevated. If a person be struck with lightning, throw pailfuls of cold water on the head and body, and apply mustard poultices on the stomach, with friction of the whole body and inflation of the lungs, as in the case of drowning. The same mode is to be used when persons are stupefied by fumes of coal, or bad air. In thunderstorms, shut the doors and windows. The safest part of a room is its centre; and where there is a feather-bed in the apartment, that will be found the most secure resting-place. A lightning-rod if it be well pointed, and run deep into the earth, is a certain protection to a circle, around it, whose diameter equals the height of the rod above the highest chimney. But it protects _no farther_ than this extent. In case of fire, wrap about you a blanket, a shawl, a piece of carpet, or any other woolen cloth, to serve as protection. Never read in bed, lest you fall asleep, and the bed be set on fire. If your clothes get on fire, never run, but lie down, and roll about till you can reach a bed or carpet to wrap yourself in, and thus put out the fire. Keep young children in woolen dresses, to save them from the risk of fire. XXVIII. SEWING, CUTTING, AND MENDING. Every young girl should be taught to do the following kinds of stitch with propriety: Over-stitch, hemming, running, felling, stitching, back-stitch and run, buttonhole-stitch, chain-stitch, whipping, darning, gathering, and cross-stitch. In doing over-stitch, the edges should always be first fitted, either with pins or basting, to prevent puckering. In turning wide hems, a paper measure should be used, to make them even. Tucks, also, should be regulated by a paper measure. A fell should be turned, before the edges are put together, and the seam should be over-sewed before felling. All biased or goring seams should be felled, for stitching, draw a thread, and take up two or three threads at a stitch. In cutting buttonholes, it is best to have a pair of scissors, made for the purpose, which cut very neatly. For broadcloth, a chisel and board are better. The best stitch is made by putting in the needle, and then turning the thread round it near the eye. This is better than to draw the needle through, and then take up a loop. A stay thread should first be put across each side of the buttonhole, and also a bar at each end before working it. In working the buttonhole, keep the stay thread as far from the edge as possible. A small bar should be worked at each end. Whipping is done better by sewing _over_, and not under. The roll should be as fine as possible, the stitches short, the thread strong, and in sewing, every gather should be taken up.
