“Here, then, is a clearly defined but very intermittent line of volcanic action along our entire east coast for over two thousand miles. Yet to-day there is not only not one active volcano on the whole of that area, but not even one clearly authentic dead one. There is nothing to show whence came the basalt of the Darling Downs, the Big Scrup, or the Atherton Tableland, unless in the last case the two deep freshwater lakes, Barrine and Eacham, the Barrang and Zeetcham of the aboriginals, represent the craters of extinct volcanoes.
“Whence, then, came the basalt spread along a narrow line of our east coast for two thousand miles, and all of it east of the Dividing Range? There is a lot of room for theories....
“When the late Captain Audley Coote was laying the cable from New Caledonia to Sandy Cape, at the north end of Fraser Island, on the South Queensland coast, he passed a submerged mountain 6000 feet in height, and found a tremendous chasm, so deep that they could find no bottom, and had to work the cable round the edge. When he reached the coast of Fraser Island he got the same soundings as Cook and Flinders and the Admiralty survey in the ’sixties, six to eight fathoms, but there came a break in the cable in after years, located in that six and eight fathom area, and they found the broken cable hanging over a submarine precipice of eight hundred feet!
“That I read in Captain Coote’s own manuscript journal, and it was confirmed by Captain John Mackay, the Brisbane harbourmaster, who assured me that an 800 feet chasm had suddenly formed there in the bottom of the ocean.
“On the coast of Japan, the ocean bottoms sank in one place suddenly from four or five fathoms to 4,000 feet.
“The old Fraser Island aboriginals told me that the deep blue lake, two miles from the White Cliffs, was once a level plateau, on which their fathers held fights and corroborees, and that it sank in one night. On the North Queensland coast, there is fairly shallow water from the seashore out to the edge of the Barrier, and then the ocean goes down to depths up to two and three thousand feet, so if the sea were removed you would look down from the outer Barrier into a tremendous valley with a wall of granite cliffs.
“When the town of Port Royal in Jamaica was destroyed by an earthquake on June 7, 1692, the houses all disappeared into an ocean chasm 300 feet in depth; and in the terrible earthquake at Lisbon, 1755, destroying 2,000 houses and 5,000 people, the wharves and piers, and even the vessels lying beside them, disappeared into some tremendous gulf, leaving no trace whatever.
“It is a singular fact that the heights of the loftiest mountains correspond with the depths of the deepest seas, and that the 29,000 feet of Mount Everest is equal with what is known as the ‘Tuscarora Deep,’ fathomed by the U.S.A. vessel Tuscarora.
Islands That Vanished.
“From the days of Seneca there are records of islands suddenly appearing before astonished mariners, and others disappearing suddenly before mariners equally astonished. In the dreadful volcanic explosion of Krakatoa in August, 1883, one mountain peak was blown to pieces, while others were thrown up from the ocean. The tidal wave created by Krakatoa destroyed 40,000 people, and the air wave from the concussion pulsated three times round the world. And Krakatoa and the Javanese volcanoes are only a short distance from the coast of Australia!
