After having read thus far, it will be of interest to learn the geological history of Mu and to know the scientific cause of her destruction.
I have already shown how the subterranean foundation of this vast continent was undermined by the volcanic gases. Granite, the primary rock in the formation of the earth's crust, appears to have been honeycombed with huge chambers and cavities and these were filled with highly explosive volcanic gases. When these chambers were emptied of their gases the supporting roofs caved in and the submersion of the land above logically followed.
My investigations have proved that the calamity which overtook this early civilization was due to the emptying of a series of isolated upper gas chambers that were upholding the land and which were probably connected with each other by cracks and fissures.
In order to make clear to the reader what I mean when referring to upper, middle and lower chambers and isolated chambers, I have made a sketch of groups of Archaean gas chambers, together with an explanation.
Sketch of Archaean Gas Chambers
Fig. B. The probable Condition underlying Mu before her Submersion
Division X runs from 5 to 10 miles below the earth's surface. These are live chambers, constantly receiving from Division W fresh gases which pass from chamber to chamber through cracks and fissures.
To drive additional gases into the isolated chambers of Division O, volcanic workings must first open cracks and fissures from Chambers X to O  and then from O  to O .
Gases coming from the chambers of Division W, which are in communication with the earth's center, must first flow into Chambers X and overcompress them. This would necessitate the raising of the roofs of these chambers to make room for the new gases.
In raising the roofs, the rocks forming them would be split and fractured, forming passageways for gases from Chambers X into Chambers O . In time Group O  would become overcompressed.
Gas belts run at irregular depths below the earth's surface. From various observations of certain phenomena covering a period of over fifty years, I have come to the conclusion that, generally, the great gas belts have been forged along the upper half of the middle series and the lower parts of the upper series. Gas belts do not run at regular distances below the earth's surface, as I have indicated, but vary considerably. A section may run through Division W.
Fig. C shows a series of chambers, O  corresponding with O  in Cuts A and B. These are connected with each other by fissures and passageways.
Fig. D shows the principal gas belts that now run under and around the Pacific Ocean.
During the forging of the belts, Chambers IO, Fig. B, became overcompressed, causing cracks and fissures in the rocks above. Then the gases entered Chambers O , where the same situation developed, and from there they escaped into Chambers O . When this happened, the roofs of Chambers O  were punctured, the gases escaped, the land crashed down to the floors of the chambers, the waters of the Pacific flowed over and Mu was no more.
It is my belief that the supporting chambers which upheld Mu were very near the surface of the land. I base this opinion on the depths of the Pacific Ocean, the Troano Manuscript, the Codex Cartesianus and the Lhasa Record.
"the land was rended and torn to pieces""quivering like the leaves of a tree in a storm""rising and falling like the waves of the ocean""during the night went down"
That the chambers sustaining Mu were near the surface and not deep down is proved by the fact that had they been deep down, the land would have been sufficiently thick to form retaining angles to uphold it after it had been raised like our mountain ranges.
Lands and continents have thus been submerged since the beginning of time. We have instances of this through the pre-Cambrian Times, the Paleozoic Time, the Mesozoic and Cenozoic Times, through the Pleistocene Period, and down, in fact, to the very edge of history.
It is geologically certain that the gas chambers which upheld Mu were eliminated during the forging of the Pacific division of the great central gas belt and the Pacific cross belts with their many ramifications. From the presence of certain geological phenomena I have thus come to the conclusion that it was a series of chambers that underlay and upheld Mu, and not one huge chamber, as was the case with Atlantis.
1. The difference in the depths of the Pacific Ocean between the various groups of islands shows that with each varying depth there was a different chamber, or one chamber under another that was eliminated. Had there been only one chamber the bottom of the Pacific Ocean would be comparatively level.
2. We find that certain islands were once parts of the continent. Had there been only one chamber these could not have remained above water.
3. These islands lay over the passageways between the chambers and not over the chambers themselves. As there was no chamber beneath them they did not go down.
4. That the chambers were connected is shown by the islands, revealing volcanic workings. The gases worked under them from chamber to chamber. This naturally changed their contour and they became mountainous and jagged.
But how, will probably be asked, does this affect the story of Mu? If the reader will go back he will recall that, in a previous chapter describing the destruction of Mu, it was shown how these treacherous gas belts were the direct cause of the submersion which sent the Motherland of Man down in an abyss of scorching flames and rushing waters. There is no question in my mind but that the land of Mu was upheld by a series of upper isolated gas chambers, marked in the diagrams Oa.
The exact location, area and height of each chamber is unknown. On surmise, based upon the positions of the islands, I have given the location of several of these chambers. I do not presume to say that they are absolutely correct in all minute details, but they do show the honeycombed condition of the rocks directly under Mu and the shallow depths of many parts of the Pacific Ocean show that they were near the surface.
As a geological proposition, my next step will be to note a few of the many large extinct volcanoes that are to be found among the Polynesian Islands. Up to the present time, nowhere upon the face of the earth are to be found evidences of volcanic outbursts equal to those found in Polynesia. These tremendous gaping mouths bear evidence of the compressed forces deep down within the earth's core that finally became unleashed and burst forth with a fury of destruction unequaled in the history of the world.
Kilauea is an extinct volcano on one of the Hawaiian Islands, the crater of which measures three miles in diameter. Imagine a mouth of this size taxed to fullest capacity suddenly vomiting forth its destructive fire, smoke and lava! A flood of fire, smoke and lava three miles in diameter! To what height did it ascend? Without doubt, thousands of feet, when we consider the tremendous motive power behind it.
Awe-inspiring as Kilauea was, there were probably others still larger.
The size of the chamber that was being emptied of gases, the immeasurable quantities of gases in the chamber, the force exerted by the overcompressed gases forming the belt, and the weight of the land above that rested on them and which finally forced them through the craters and released the demons of destruction that sprang at the throat of Mu and throttled her.
When the northern main division of the great central gas belt was completed through the Pacific, a safety valve was formed to take care of future accumulations of the belt in this section. A new crater pierced through the center of Kilauea. This new crater is only 300 yards in diameter and is called Halemaumau. While Halemaumau is only one-eighteenth of the diameter of Kilauea, it nevertheless ranks among the largest craters of today and gives an idea, by comparison, of the enormity of its predecessor.
The northern main Pacific division of the great central gas belt runs directly under the Hawaiian Islands. At the Hawaiian Islands it is nearer to the surface than at any other point along its whole course, which encircles the central part of the earth.
The Niuafou is another famous crater that is of interest to the archaeologist. Niuafou is a small island to the northeast of the Fiji Islands, nearly midway between Fiji and Samoa. The Niuafou extinct crater is two miles in diameter. Since the time it helped in the work of submerging the land of Mu it has filled up with water and now forms a lake.
The foregoing are only conspicuous examples of the many immense extinct volcanoes found among the Polynesian Islands. We doubt if anything in the nature of volcanic disturbances has ever before or since in the earth's history happened that would compare in horror to the appalling cataclysm that befell the race of man when these volcanic workings blew off the lid of the earth and destroyed the land of Mu.
Geology tells us that the western shores of North America were once raised. Geology has ever been guilty of putting the cart before the horse and this is one more instance. Instead of the western shores of North America having been raised and the shore line thus extended, it was, as a matter of fact, the lowering of the level of the Pacific Ocean that extended the shore lines.
The land of Mu was an immense continent covering nearly one-half of the Pacific Ocean. In some places the ocean went down thousands of feet. In order to fill up this vast hole, which was from 5000 to 6000 miles long and at least 2000 or 3000 miles broad, to the present depths of the ocean, the surrounding waters had to be drawn upon.
It may be asked: How did it happen that the waters of the Atlantic Ocean did not flow around Cape Horn into the Pacific Ocean and thus level off the waters again without drawing them away from surrounding shores? In answer to this I say that the Atlantic Ocean had its own troubles to attend to during this period of the earth's history as the following list of submerged lands will show:
The land of Mu in the Pacific Ocean, which was several thousands of miles long and thousands of miles wide.
The Bering land bridge in the north Pacific Ocean, connecting America with Asia. This bridge was not the narrow strip of land assigned to it by geology. Its southern shore line ran from Alaska to Kamchatka by way of the Aleutian Islands.
This submerged land has furnished scientists with a scapegoat to account for all the unaccountable things in America. Whenever anything has come up that could not be understood by the scientists, and that is quite frequent, it was always agreeably settled among themselves that it undoubtedly came to America from Asia by way of the Bering land bridge. Why Asia should have been selected to account for what is unaccountable I cannot imagine except that, as nothing is known about eastern Asia, there was no fear of contradiction.
Then there are the Pacific minor submersions. A stretch of land running down from California to the northwest corner of Colombia went down. This, apparently, was a narrow strip. Land was also submerged where the Malay Archipelago now stands, but the extent of this land is not known.
Atlantis was situated in the center of the Atlantic Ocean. It was an immense continental island, and at the time of its submersion it was the center of the earth's civilization.
Then there was the overland route to Europe, in the north Atlantic Ocean. This was land between America and Greenland, and Greenland and Norway, together with a great, triangular piece whose western line ran from Iceland to Cape Finisterre in the northwest corner of France.
A small area of land also went down off the coasts of Central America, which before submersion was a part of the mainland.
All of these submersions were caused by the volcanic workings during the forging of the gas belts. The great central belt submerged Mu and Atlantis. The Pacific circuit belt submerged the Bering land bridge. The Appalachian-Iceland-Scandinavian belt submerged the overland route to Europe.
By the lowering of the levels of the ocean, many lands emerged from the water, and the shore lines of remaining lands were extended.
Apparently all these great areas of land were thickly peopled, so that the loss of life was appalling. Without doubt hundreds of millions perished. Mu, alone, accounted for 64,000,000.
This geological cycle is a complete confirmation of all the data previously furnished about the land of Mu. It provides the connection that might be termed a missing link. Geologically, it proves beyond question the existence of a great prehistoric continent of land in the Pacific Ocean.
Much of the present elevation of the islands of the Pacific Ocean is due to the lowering of the ocean's level.
I have made a somewhat rough calculation as to how much the earth's diameter has been reduced by the blowing out of gas chambers and the compacting of the rocks, and find that it totals between 17 and 21 miles.
The two divisions of the Great Central Belt were not forged at the same time, the Southern was formed later than the Northern. Neither are they at the same depth from the surface of the earth. The Southern is thousands of feet further down in the bowels of the earth and possibly miles.
Atlantis was in some respects in a similar position to Mu, both lands were being upheld above water by isolated gas chambers, both lay over the pathway of a forming belt. In both cases the isolated chambers were tapped by the forming belt and blown out, in both cases the land went down and was submerged, and, strange to say, the same belt was the double assassin.
From the fact that this great belt was formed where it is and the land above submerged we gather that there must have been a great depth of rock, free of chambers, between the chambers which helped to form the belt, and the isolated chambers which were upholding Atlantis and the Land of Mu.
From a geological standpoint there is no date shown when Atlantis was submerged except that it went down when the Great Central Gas Belt was formed under the North Atlantic Ocean. But what geology lacks, history provides and shows us that Atlantis first went down to awash 9500 B. C. and subsequently to where she lies today, Atlantis was a large continent and ultimately went down thousands of feet below the surface of the water. By her sinking an equally big hole was made in the waters in the center of the North Atlantic.
The submergence of Atlantis and the "Overland Route" affected, by extension, the coast lines of Eastern America, Western Europe and Northwest Africa.
- The elimination of the Amazonian Sea
- The drying out of the Mississippi Valley
- The drying out of the St. Lawrence Valley
- The emerging of Florida, and
- The general extension of the Atlantic Coast Line of North America. At one time both the Mississippi Valley and the Valley of the St. Lawrence were shallow arms of the sea
