In looking at a selenographic map, one peculiarity strikes us. Contrary to the arrangement followed for that of the Earth and Mars, the continents occupy more particularly the southern hemisphere of the lunar globe. These continents do not show such decided, clear, and regular boundary lines as South America, Africa, and the Indian peninsula. Their angular, capricious, and deeply indented coasts are rich in gulfs and peninsulas. They remind one of the confusion in the islands of the Sound, where the land is excessively indented. If navigation ever existed on the surface of the moon, it must have been wonderfully difficult and dangerous; and we may well pity the Selenite sailors and hydrographers; the former, when they came upon these perilous coasts, the latter when they took the soundings of its stormy banks. Illustration: HOW MANY PEOPLE HAVE HEARD SPEAK OF THE MOON. We may also notice that, on the lunar sphere, the south pole is much more continental than the north pole. On the latter, there is but one slight strip of land separated from other continents by vast seas. Towards the south, continents clothe almost the whole of the hemisphere. It is even possible that the Selenites have already planted the flag on one of their poles, whilst Franklin, Ross, Kane, Dumont d'Urville, and Lambert have never yet been able to attain that unknown point of the terrestrial globe. As to islands, they are numerous on the surface of the moon. Nearly all oblong or circular, and as if traced with the compass, they seem to form one vast Archipelago, equal to that charming group lying between Greece and Asia Minor, and which mythology in ancient times adorned with most graceful legends. Involuntarily the names of Naxos, Tenedos, and Carpathos, rise before the mind, and we seek vainly for Ulysses' vessel or the "clipper" of the Argonauts. So at least it was in Michel Ardan's eyes. To him it was a Grecian Archipelago that he saw on the map. To the eyes of his matter-of-fact companions, the aspect of these coasts recalled rather the parcelled-out land of New Brunswick and Nova Scotia; and where the Frenchman discovered traces of the heroes of fable, these Americans were marking the most favourable points for the establishment of stores in the interests of lunar commerce and industry.
