This is a matter of convenience inarrangement, based upon the fact that the ecliptic, which, and not theequator, marks the center of the zodiac, indicates the position of thetracks of the planets among the stars; and the ecliptic, being inclined23° to the plane of the equator, lies half to the north and hal...f to thesouth of the latter. Those who, after all, may not care to consult the ephemeris in order tofind the planets, may be able to locate them, simply from a knowledge oftheir situation among the constellations. Some ordinary almanacs tell inwhat constellations the principal planets are to be found at varioustimes of the year. Having once found them in this way, it iscomparatively easy to keep track of them thereafter through a generalknowledge of their movements.
