Lead to that of primary lead; some refining processes may be skipped depending on the material recycled and its potential contamination. Of the sources of lead for recycling, lead–acid batteries are the most important; lead pipe, sheet, and cable sheathing are also significant. Contrary to popular belief, pencil leads in wooden pencils have never been made from lead. When the pencil originated as a wrapped graphite writing tool, the particular type of graphite used was named "plumbago" (literally, "act for lead" or "lead mockup"). Lead metal has several useful mechanical properties, including high density, low melting point, ductility, and relative inertness.
Lead (leg) So when an animal is in a rotatory gait, it is called disunited, due to different leading legs in the front and hind. A horse is better balanced when on the correct "lead" of the canter, that is to say, the lead which corresponds to the direction of travel. If a horse is on the wrong lead, it may be unbalanced and will have a much harder time making turns. However, there is an exception to this general rule, the counter canter, or counter-lead, a movement used in upper-level dressage, where a horse may be deliberately asked for what would
