beings, resulting from an eruption which destroyed towns like Telok Betong, Anjer, Tyringin, etc., besides numerous villages and hamlets on the shores of Java and Sumatra, and caused the destruction of more than 36,000 souls?

But it is to results of a very different kind, and on a much more extended scale, that we must turn if we would properly estimate the magnitude, the wide-spreading and far-reaching influences, and the extraordinary character, of the Krakatoa outburst of 1883.

In the first place, it is a fact, testified to by some of the best-known men of science, that the shock of the explosion extended _appreciably_ right round the world, and seventeen miles (some say even higher!) up into the heavens.

Mr. Verbeek, in his treatise on this subject, estimates that a cubic mile of Krakatoa was propelled in the form of the finest dust into the higher regions of the atmosphere--probably about thirty miles! The dust thus sent into the sky was of "ultra-microscopic fineness," and it travelled round and round the world in a westerly direction, producing those extraordinary sunsets and gorgeous effects and afterglows which became visible in the British Isles in the month of November following the eruption; and the mighty waves which caused such destruction in the vicinity of Sunda Straits travelled--not once, but at least--six times round the globe, as was proved by trustworthy and independent observations of tide-gauges and barometers made and recorded at the same time in nearly all lands--including our own.

Other volcanoes, it is said by those who have a right to speak in regard to such matters, have ejected more "stuff," but not one has equalled Krakatoa in the intensity of its explosions, the appalling results of the sea-waves, the wonderful effects in the sky, and the almost miraculous nature of the sounds.

Seated on a log under a palm-tree in Batavia, on that momentous morning of the 27th, was a sailor who had been left behind sick by Captain Roy when he went on his rather Quixotic trip to the Keeling Islands. He was a somewhat delicate son of the sea. Want of self-restraint was his complaint--leading to a surfeit of fruit and other things, which terminated in a severe fit of indigestion and indisposition to life in general. He was smoking--that being a sovereign and infallible cure for indigestion and all other ills that flesh is heir to, as every one knows!

"I say, old man," he inquired, with that cheerful tone and air which usually accompanies incapacity for food. "Do it always rain ashes here?"

The old man whom he addressed was a veteran Malay seaman.

"No," replied the Malay, "sometimes it rain mud--hot mud."

"Do it? Oh! well--anything for variety, I s'pose," returned the sailor, with a growl which had reference to internal disarrangements.

"Is it often as dark as this in the daytime, an' is the sun usually green?" he asked carelessly, more for the sake of distracting the mind from other matters than for the desire of knowledge.

"Sometime it's more darker," replied the old man. "I've seed it so dark that you couldn't see how awful dark it was."

As he spoke, a sound that has been described by ear-witnesses as "deafening" smote upon their tympanums, the log on which they sat quivered, the earth seemed to tremble, and several dishes in a neighbouring hut were thrown down and broken.

"I say, old man, suthin' busted there," remarked the sailor, taking the pipe from his mouth and quietly ramming its contents down with the end of his blunt forefinger.

The Malay looked grave.

"The gasometer?" suggested the sailor.

"No, that _never_ busts."

"A noo mountain come into action, p'raps, an' blow'd its top off?"

"Shouldn't wonder if that's it--close at hand too. We's used to that here. But them's bigger cracks than or'nar'."

The old Malay was right as to the cause, but wrong as to distance. Instead of being a volcano "close at hand," it was Krakatoa eviscerating itself a hundred miles off, and the sound of its last grand effort "extended over 50 degrees = about 3000 miles."

On that day all the gas lights were extinguished in Batavia, and the pictures rattled on the walls as though from the action of an earthquake. But there was no earthquake. It was the air-wave from Krakatoa, and the noise produced by the air-waves that followed was described as "deafening."

The effect of the sounds of the explosions on the Straits Settlements generally was not only striking, but to some extent amusing. At Carimon, in Java--355 miles distant from Krakatoa--it was supposed that a vessel in distress was firing guns, and several native boats were sent off to render assistance, but no distressed vessel was to be found! At Acheen, in Sumatra--1073 miles distant--they supposed that a fort was being attacked and the troops were turned out under arms. At Singapore--522 miles off--they fancied that the detonations came from a vessel in distress and two steamers were despatched to search for it. And here the effect on the telephone, extending to Ishore, was remarkable. On raising the tubes a perfect roar as of a waterfall was heard. By shouting at the top of his voice, the clerk at one end could make the clerk at the other end hear, but he could not render a word intelligible. At Perak--770 miles off--the sounds were thought to be distant salvos of artillery, and Commander Hon. F. Vereker, R.N., of H.M.S. _Magpie_, when 1227 miles distant (in lat. 5 deg. 52' N. long. 118 deg. 22' E.), states that the detonations of Krakatoa were distinctly heard by those on board his ship, and by the inhabitants of the coast as far as Banguey Island, on August 27th. He adds that they resembled distant heavy cannonading. In a letter from St. Lucia Bay--1116 miles distant--it was stated that the eruption was plainly heard all over Borneo. A government steamer was sent out from the Island of Timor--1351 miles off--to ascertain the cause of the disturbance! In South Australia also, at places 2250 miles away, explosions were heard on the 26th and 27th which "awakened" people, and were thought worthy of being recorded and reported. From Tavoy, in Burmah--1478 miles away--the report came--"All day on August 27th unusual sounds were heard, resembling the boom of guns. Thinking there might be a wreck or a ship in distress, the Tavoy Superintendent sent out the police launch, but they 'could see nothing.'" And so on, far and near, similar records were made, the most distant spot where the sounds were reported to have been heard being Rodriguez, in the Pacific, nearly 3000 miles distant!

One peculiar feature of the records is that some ships in the immediate neighbourhood of Krakatoa did not experience the shock in proportionate severity. Probably this was owing to their being so near that a great part of the concussion and sound flew over them--somewhat in the same way that the pieces of a bomb-shell fly over men who, being too near to escape by running, escape by flinging themselves flat on the ground.

Each air-wave which conveyed these sounds, commencing at Krakatoa as a centre, spread out in an ever-increasing circle till it reached a distance of 180 deg. from its origin and encircled the earth at its widest part, after which it continued to advance in a contracting form until it reached the antipodes of the volcano; whence it was reflected or reproduced and travelled back again to Krakatoa. Here it was turned right-about-face and again despatched on its long journey. In this way it oscillated backward and forward not fewer than six times before traces of it were lost. We say "traces," because these remarkable facts were ascertained, tracked, and corroborated by independent barometric observation in all parts of the earth.

For instance, the passage of the great air-wave from Krakatoa to its antipodes, and from its antipodes back to Krakatoa, was registered six times by the automatic barometer at Greenwich. The instrument at Kew Observatory confirmed the records of Greenwich, and so did the barometers of other places in the kingdom. Everywhere in Europe also this fact was corroborated, and in some places even a seventh oscillation was recorded. The Greenwich record shows that the air-waves took about thirty-six hours to travel from pole to pole, thus proving that they travelled at about the rate of ordinary sound-waves, which, roughly speaking, travel at the rate of between six and seven hundred miles an hour.

The height of the sea-waves that devastated the neighbouring shores, being variously estimated at from 50 to 135 feet, is sufficiently accounted for by the intervention of islands and headlands, etc., which, of course, tended to diminish the force, height, and volume of waves in varying degrees.

These, like the air-waves, were also registered--by self-acting tide-gauges and by personal observation--all over the world, and the observations _coincided as to date with the great eruptions of the 26th and 27th of August_. The influence of the sea-waves was observed and noted in the Java sea--which is shallow and where there are innumerable obstructions--as far as 450 miles, but to the west they swept over the deep waters of the Indian Ocean on to Cape Horn, and even, it is said, to the English Channel.

The unusual disturbance of ocean in various places was sufficiently striking. At Galle, in Ceylon, where the usual rise and fall of the tide is 2 feet, the master-attendant reports that on the afternoon of the 27th four remarkable waves were noticed in the port. The last of these was preceded by an unusual recession of the sea to such an extent that small boats at their anchorage were left aground--a thing that had never been seen before. The period of recession was only one-and-a-half minutes; then the water paused, as it were, for a brief space, and, beginning to rise, reached the level of the highest high-water mark in less than two minutes, thus marking a difference of 8 feet 10 inches instead of the ordinary 2 feet.

At one place there was an ebb and flood tide, of unusual extent, within half-an-hour. At another, a belt of land, including a burying-ground, was washed away, so that according to the observer "it appeared as if the dead had sought shelter with the living in a neighbouring cocoa-nut garden!" Elsewhere the tides were seen to advance and recede ten or twelve times--in one case even twenty times--on the 27th.

At Trincomalee the sea receded three times and returned with singular force, at one period leaving part of the shore suddenly bare, with fish struggling in the mud. The utilitarian tendency of mankind was at once made manifest by some fishermen who, seizing the opportunity, dashed into the struggling mass and began to reap the accidental harvest, when--alas for the poor fishermen!--the sea rushed in again and drove them all away.

In the Mauritius, however, the fishers were more fortunate, for when their beach was exposed in a similar manner, they succeeded in capturing a good many fish before the water returned.

Even sharks were disturbed in their sinister and slimy habits of life by this outburst of Krakatoa--and no wonder, when it is recorded that in some places "the sea looked like water boiling heavily in a pot," and that "the boats which were afloat were swinging in all directions." At one place several of these monsters were flung out of their native home into pools, where they were left struggling till their enemy man terminated their career.

Everywhere those great waves produced phenomena which were so striking as to attract the attention of all classes of people, to ensure record in most parts of the world, and to call for the earnest investigation
