“We have some large soft bodied animals, something akin to your large mollusks and others having a cartilaginous frame, but we have no bony fishes. These animals are sometimes caught and turned into food products, the same as other organic refuse, but never eaten directly, as we are vegetarians. The amount of water surface on our planet is quite small compared with yours. The seas are narrow, but of immense depth. Indeed, some of them are known to have passages communicating directly through the planet and connecting the waters of the exterior continent, with those of the “Pocket”. The fluctuation of the tides takes place bi-monthly, with enormous force through these “bores.” When the moon is between the earth and sun the tide rises on the exterior continent, and when on the opposite side, it rises in the interior continent, the amount of the rise being very great in the neighborhood of these “bores,” but inconsiderable elsewhere.” “Your climate I suppose is very different from ours—of course it must be.” “Yes certainly, and the climate of the interior continent differs greatly from that of the exterior. On the polar regions of the exterior continent, we experience the extreme change of seasons, that occur on earth, from a very cold winter to a very hot summer—all in the space of about 29½ of your days or 709 hours. In the equatorial regions, however, the extremes are greatly tempered by the winds, which always blow toward the position of the sun, by the great evaporation that takes place during the day, and by the fact that the air of the equatorial belt is both higher and denser than that in the polar regions. In many cases, the upper air is charged with heavy clouds, that remain suspended all night or all winter, as you choose, and these prevent the land from becoming very cold.” “Vegetation must come on very rapidly during your little summers,” I observed.
