George and Milli then took up again the problem of saving the outer earth from the threatened invasion. Milli suggested that they go peaceably with the expedition, and then warn the authorities of America at the first opportunity after their arrival; but Abbot pointed out that this would merely result in their both being shut up in some insane asylum, as no one would believe such a crazy story as theirs.

There were sufficient quantities of explosives in storage to blast a hole through the wall of the caves, letting in the sea and killing everyone in the city. Dolf planned to set this off with a time fuse, upon the departure of the expedition. Thus Thig and the people who were left behind—about two-thirds of the total population of the city—would be destroyed, and the fish would have no one to send after Dolf and his followers to dictate to them on the upper earth.
