“No doubt,” said I, “the serpents originated in that way. They formerly possessed limbs, because many species still have the rudiments of them. In some cases these remnants show themselves like little hooks on the outside of the skin, while many others are covered up by the skin and are not seen at all. But all that retrogressive adaptation by which they lost their limbs, must have been practically completed before our race possessed any semblance of their present form and condition.”
“The earth,” he proceeded, “was full of contending races, and of course the backset that was imposed on the snakes, was contributed to by others, as well as men, but the latter were among the last and as regards the particular family of reptiles in question, the most formidable and effectual opponents. Some of your ancient traditions and literature contain allusions to this contest, the reptile being styled _Nachash_. You preserve an allusion to this ancient competition, in the legends of the Devil, who represents the reptile, and is often called the serpent etc. I recall this history, only to show you that the essential qualities of predominance do not inhere in any particular animal form. Your planet escaped the final domination of a reptile instead of a mammal, by only a little. As you have already perceived the dominant race on our planet is an articulate.”
“I confess,” said I, “that you have demonstrated the possibility of a development among the articulates quite equal at least to that of mammals. You must have animals of some sort in your seas and lakes; what do you do with them?”
“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.”
