Half way from the Syrtis Major to the Lake of the Sun another great connecting link between the Southern and Northern ocean basins, called on our maps of Mars the Indus, existed, and through this channel we knew that another great current must be setting from the south toward the north. The flood that we had started would reach and break the banks of the Indus within one day. Flooding Hundreds of Canals. The flood travelling in the other direction, towards the east, would have considerably further to go before reaching the neighborhood of the Lake of the Sun. It, too, would involve hundreds of great canals as it advanced and would come plunging upon the Lake of the Sun and its surrounding forts and cities, probably about half a day later than the arrival of the deluge that travelled towards the west. Now that we had let the awful destroyer loose we almost shrank from the thought of the consequences which we had produced. How many millions would perish as the result of our deed we could not even guess. Many of the victims, so far as we knew, might be entirely innocent of enmity toward us, or of the evil which had been done to our native planet. But this was a case in which the good--if they existed--must suffer with the bad on account of the wicked deeds of the latter. I have already remarked that the continents of Mars were higher on their northern and southern borders where they faced the great oceans. These natural barriers bore to the main mass of the land somewhat the relation of the edge of a shallow dish to its bottom. Their rise on the land side was too gradual to give them the appearance of hills, but on the side toward the sea they broke down in steep banks and cliffs several hundred feet in height. We guessed that it would be in the direction of these elevations that the inhabitants would flee, and those who had timely warning might thus be able to escape in case the flood did not--as it seemed possible it might in its first mad rush--overtop the highest elevations on Mars. A Dreadful Scene. As day broke and the sun slowly rose upon the dreadful scene beneath us, we began to catch sight of some of the fleeing inhabitants. We had shifted the position of the fleet toward the south, and were now suspended above the southeastern corner of Aeria. Here a high bank of reddish rock confronted the sea, whose waters ran lashing and roaring along the bluffs to supply the rapid draught produced by the emptying of the Syrtis Major. Along the shore there was a narrow line of land, hundreds of miles in length, but less than a quarter of a mile broad, which still rose slightly above the surface of the water, and this land of refuge was absolutely packed with the monstrous inhabitants of the planet who had fled hither on the first warning that the water was coming.
