I have now given a general description of this celestial wonder, but some may still doubt whether any thing can be ascertained with respect to objects so far removed. If the most accurate calculations had not already been made in respect to many of the heavenly bodies, how could the tempest tossed mariner, after being driven for days, and sometimes weeks, sailing on all points of the compass, and perhaps, not have known his position from the time he had taken his departure from his port, only by dead reckoning, nothing in sight but sea and sky, ascertain his true position? Just look,--there stands the captain, on some convenient part of the deck of his ship, holding in his hand a three cornered instrument, called a Sextant, measuring the distance between the sun and moon, or if it be in the night, between the moon and some lunar star, (which is millions on millions of miles removed from the Solar System,) noting the moment by his watch when he brings the outer or inner edges of these two celestial objects to touch; then measuring their distance from the horizon. With the help of a Nautical Almanac, (which had been published years before,) in the course of twenty minutes he so confidently ascertains his position, (however strange it may appear to landsmen,) that he would, after running ten or one hundred miles more or less, as the case may be, direct one of his crew to go to the mast head, and tell him at the same time in what direction to look for land. Presently the cry would come down, thrilling through every soul in the ship, "Land ho!" "Where away?" "Off the starboard bow, sir, where you told me to look." Such instances are not rare, but of daily occurrence. "How could that be?" says one, "it looks like a miracle!" So it would be, if the great God had not directed these celestial objects to move in perfect harmony. A place for every one, and every one in its place.
