The Old Ones had used curious weapons of molecular disturbance against the rebel entities, and in the end had achieved a complete victory. Thereafter the sculptures showed a period in which Shoggoths were tamed and broken by armed Old Ones as the wild horses of the American west were tamed by cowboys.
Though during the rebellion the Shoggoths had shown an ability to live out of water, this transition was not encouraged—since their usefulness on land would hardly have been commensurate with the trouble of their management.
During the Jurassic Age the Old Ones met fresh adversity in the form of a new invasion from outer space—this time by half-fungous, half-crustacean creatures—creatures undoubtedly the same as those figuring in certain whispered hill legends of the north, and remembered in the Himalayas as the Mi-Go, or Abominable Snow Men.
To fight these beings the Old Ones attempted, for the first time since their terrene advent, to sally forth again into the planetary ether; but, despite all traditional preparations, found it no longer possible to leave the earth’s atmosphere. Whatever the old secret of interstellar travel had been, it was now definitely lost to the race.
In the end the Mi-Go drove the Old Ones out of all the northern lands, though they were powerless to disturb those in the sea. Little by little the slow retreat of the elder race to their original Antarctic habitat was beginning.
It was curious to note from the pictured battles that both the Cthulhu spawn and the Mi-Go seem to have been composed of matter more widely different from that which we know than was the substance of the Old Ones. They were able to undergo transformations and reintegrations impossible for their adversaries, and seem therefore to have originally come from even remoter gulfs of cosmic space.
The Old Ones, but for their abnormal toughness and peculiar vital properties, were strictly material, and must have had their absolute origin within the known space-time continuum—whereas the first sources of the other beings can only be guessed at with bated breath. All this, of course, assuming that the nonterrestrial linkages and the anomalies ascribed to the invading foes are not pure mythology. Conceivably, the Old Ones might have invented a cosmic framework to account for their occasional defeats, since historical interest and pride obviously formed their chief psychological element. It is significant that their annals failed to mention many advanced and potent races of beings whose mighty cultures and towering ethics figure persistently in certain obscure legends.
The changing state of the world through long geologic ages appeared with startling vividness in many of the sculptured maps and scenes. In certain cases existing science will require revision, while in other cases its bold deductions are magnificently confirmed.
As I have said, the hypothesis of Taylor, Wegener, and Joly that all the continents are fragments of an original Antarctic land mass which cracked from centrifugal force and drifted apart over a technically viscous lower surface—an hypothesis suggested by such things as the complimentary outlines of Africa and South America, and the way the great mountain chains are rolled and shoved up—receives striking support from this uncanny source.
Maps evidently showing the Carboniferous of a hundred million or more years ago displayed significant rifts and chasms destined later to separate Africa from the once continuous realms of Europe (then the Valusia of primal legend), Asia, the Americas, and the Antarctic continent.
Other charts—and most significantly one in connection with the founding fifty million years ago of the vast dead city around us—showed all the present continents well differentiated. And in the latest discoverable specimen—dating perhaps from the Pliocene Age—the approximate world of today appeared quite clearly despite the linkage of Alaska with Siberia, of North America with Europe through Greenland, and of South America with the Antarctic continent through Graham Land.
In the Carboniferous map the whole globe—ocean floor and rifted land mass alike—bore symbols of the Old Ones’ vast stone cities, but in the later charts the gradual recession toward the Antarctic became very plain.
The final Pliocene specimen showed no land cities except on the Antarctic continent and the tip of South America, nor any ocean cities north of the fiftieth parallel of South Latitude. Knowledge and interest in the northern world, save for a study of coast lines probably made during long exploration flights on those fan-like membranous wings, had evidently declined to zero among the Old Ones.
Destruction of cities through the upthrust of mountains, the centrifugal rending of continents, the seismic convulsions of land or sea bottom, and other natural causes was a matter of common record; and it was curious to observe how fewer and fewer replacements were made as the ages wore on.
The vast dead megalopolis that yawned around us seemed to be the last general center of the race—built early in the Cretaceous Age after a titanic earth buckling had obliterated a still vaster predecessor not far distant.
It appeared that this general region was the most sacred spot of all, where reputedly the first Old Ones had settled on a primal sea bottom. In the new city—many of whose features we could recognize in the sculptures, but which stretched fully a hundred miles along the mountain range in each direction beyond the farthest limits of our aerial survey—there were reputed to be preserved certain sacred stones forming part of the first sea-bottom city, which were thrust up to light after long epochs in the course of the general crumpling of strata.

Naturally, Danforth and I studied with special interest and a peculiarly personal sense of awe everything pertaining to the immediate district in which we were. Of this local material there was naturally a vast abundance.
On the tangled ground level of the city we
