Before Forrester could reply, the darkening sky was lit up northward by a sudden blaze of light that brought everyone to his feet in consternation. As one of them afterwards remarked, it was like the blinding glare of ten thousand flashlights. It was gone in an instant, and the universe seemed plunged into utter blackness.
The men stood at gaze. Perhaps a minute after the flash, a roar like the gunfire of all the world's fleets rolled and thundered dully about them. The earth trembled beneath their feet. Presently the air became hot, and a shower of fine dust mingled with stones bespattered them.
"A volcano!" cried one.
"No; that is the answer to your question," said Beresford quietly.
"What do you mean, sir?"
"What we feared might happen, has happened. I haven't a doubt of it. Our mining must have weakened the embankment, the stream broke through and plunged into the pit, tons of water were decomposed by the mysterious rays, and the explosion has shattered everything with volcanic force."
"Ay, and there's the end of the Old Man of the Mountain," Mackenzie said gravely.
The workers in the Laibach observatory recorded a seismic disturbance, locating it somewhere in the steppes of Central Asia. No authentic information, accredited by responsible men of science, ever reached them. But in course of time fantastic stories came to this country in private correspondence, and found their way into the newspapers. They were pooh-poohed, laughed at, pronounced incredible. Certain adventurous spirits did indeed slip off with more or less secrecy and hurry by the quickest route to the unknown country watered by the middle Brahmaputra. A company was even formed in London for exploiting gold in that region; but it lived feverishly and died forlorn. Persistent explorers ranged over mile upon mile of desolate country in quest of a gigantic waterfall, a marvellous cañon, and a fertile plateau that was said to be inhabited by an aboriginal race of pigmies. Of the canon they found no trace; only a number of scattered bones, large and small, announced that human beings and strange monsters had once inhabited what was now a rocky waste. A hitherto unknown river was discovered, broken for miles of its course by foaming rapids; but rapids are not waterfalls, as everybody knows.
In his rooms at Cambridge Henry Beresford sometimes shows his visitors a painted tablet from Khotan, and some strangely inscribed rolls of parchment. If pressed, he will tell a singular story, which they listen to politely, and with murmurs of "How very interesting!" totally disbelieve. The fact is that neither he, nor his friend Captain Redfern, nor certain young planters in Assam, care very much to talk about the events of those few weeks when the currents of their lives were mingled, and danger welded them into a comradeship which nothing will sever.
