“Circumnavigation in an easterly and westerly direction does not prove the earth to be globular.”The earth has been circumnavigated a great many times, and it is a common occurrence for a ship to leave England, and by steering westward all the voyage to arrive in England again without retracing an inch of her way. Similarly, we can journey round the globe, sometimes travelling on land, and sometimes on the sea, but eventually return to the starting point without at all turning back on our course. This would appear to be a certain proof that the earth’s surface is curved, nevertheless it has been pointed out that circumnavigation would be possible if the earth had a flat surface, with the north magnetic pole at its centre. A compass needle would THEN always point to the centre of the surface, and so a ship might sail due east and west, as indicated by the compass, and eventually return to the same point by describing a circle.”
