However doctors may differ concerning the way that our earth came into being, most of them agree that in its early days meteoric bodies from space flew together and produced a hotter globe than at present. Perhaps its surface was all covered with vast circular lakes of lava such as our telescopes reveal in great perfection, ring upon ring, over the surface of the moon. On the moon these rings and pits are now cold, remnant from a time when the gases from the inside of our satellite were bubbling forth from a great internal heat supply and bringing with them oceans of slag which seethed and swirled in circular pools which formed symmetrically within ramparts of their own spatter.
The earth is not without traces of similar circular ramparts in the shape of long curved chains of volcanoes, mostly in the sea, which would appear as ridges if the ocean were to dry up. The line of the Hawaiian Islands from Kauai to Mauna Loa on the large island of Hawaii is such a curved ridge, now of enormous height
