As we have seen that there is, really, no south point (or pole) but an infinity of points forming, together, a vast circumference—the boundary of the known world, with its battlements of icebergs which bid defiance to man’s onward course in a southerly direction—so there can be no east or west “points,” just as there is no “yesterday,” and no “to-morrow.” In fact, as there is one point that is fixed (the North), it is impossible for any other point to be fixed likewise. East and west are, therefore, merely directions at right angles with a north and south line: and as the south point of the compass shifts round to all parts of the circular boundary, (as it may be carried round the central North), so the directions east and west, crossing this line, continued, form a circle, at any latitude. A westerly circumnavigation, therefore, is a going round with the North Star continually on the right hand, and an easterly circumnavigation is performed only when the reverse condition of things is maintained, the North Star being on the left hand as the journey is made. These facts, taken together, form a beautiful proof that the Earth is not a globe.
