The accusation that I am not orthodox in professional geology is false. Professional geology is largely continental because its field work has been on continents. My work has been oceanic; my field, seventy percent of the earth’s surface, extending over a thick crust down to the earth core. The earth core is fluid and massive and hot, as all geology agrees. Isostasy, which postulates a thin flexible shell, is violated by the ocean deeps and the volcanic ridges. Volcanic rift echelons like the Cordillera and the Hawaiian ridge are too long to be generated as the fracture of a crust fifty miles deep. The circularity and graduated size in linear stretches of the Pacific arcs are functions of a fractured thick-shell sphere. Similar gradation of arcs is on the lunar surface. Arguments, based on the knowledge of meteors, for an iron core and for large lunar craters are without analogy. Substratum theories, from Stübel to Daly, do not agree with oceanic volcanism. Gravitational crust balance applies better to a primitive thick fault block crust than to a thin shell. Earth lavas, as natural experimental models, imitate lunar features on small and large scales. Both make consistent history for two similar globes. Volcanology has to stand as global and ancient, and any geologist may accept the reasonings here enumerated without being unorthodox. The unquestioned certainties of modern seismology, the transmission of elastic waves through the globe to sensitive recording pendulums, are that the crust is 1,800 miles thick, that the core is a heavy ball of white hot fluid, and that its temperature at crustal contact has been estimated by Verhoogen at 2200° Centigrade. The deep crust is less dense than the core, and is commonly conceded to be basic heavy rock not unlike stony meteorites. The outside shell under oceans, and over three-quarters of the earth, is covered by basaltic lava, and wherever igneous rock has been formed by volcanic action, intrusive or extrusive black basic lava recurs as dikes and outflows.

Possibly the profile is tetrahedral. My argument for this globe section is based on the following_: A globe of core, siliceous shell, and armorplate was formed by primitive volcanic eruptions.
