THE GREAT VOLCANIC ERUPTION.
In 1883 the most destructive volcanic eruption ever known occurred in the Straits of Sunda and the neighboring islands. The trouble began on Sunday morning, the 13th of May. Java, Sumatra, and Borneo were convulsed by earthquakes. The surface of the earth rocked, houses tumbled down, and big trees were shaken to the ground. Earthquakes are no rarity in those islands, but this earthquake showed no signs of ceasing. The earth quivered constantly, and from its depths there seemed to rise strange sounds and hollow explosions.
On Thursday there came a telegram from Anjer, ninety miles away, on the northwest coast of Java, intimating that a volcano had broken out at Krakatoa island, about thirty miles west of Anjer, in Sunda Strait. I was requested by the Dutch government to go to the scene of action and take scientific observations, and by four o'clock that afternoon I started with a party on board a special steamer from Batavia.
As we rounded the northern extremity of Java, we saw ascending from Krakatoa, still fifty miles away, an immense column of smoke. Its appearance changed as we approached. First it looked like flame, then it appeared to be steam, and finally it had the appearance of a pillar of fire inside one of white fleecy wool. The diameter of this pillar of fire and smoke was, I should think, at least one and a half miles. All the while we heard that sullen, thunderous roar which had been a feature of this disturbance ever since Sunday, and was now becoming louder.
We remained on deck all night and watched. The din increased till we could with difficulty hear one another's voices. Dawn approached, and when the rays of the sun fell on the shores of Krakatoa, we saw them reflected from what we thought was a river, and we resolved to steam into its mouth and disembark.
When we came to within three quarters of a mile of the shore, we discovered that what we supposed to be a river was a torrent of molten sulphur. The smell almost overpowered us. We steamed away to the windward, and made for the other side of the island.
This island, though volcanic, had up till now been quiet for at least a century. It was eight or ten miles long and four wide, and was covered with forests of fine mahogany and rosewood trees. It was inhabited by a few fishermen, but we found no signs of these people. The land, down to the water's edge, was covered with powdered pumice stone, which rained down from the clouds around the great column of fire. Everything with life had already disappeared from the landscape, which was covered with a steaming mass of stones and ashes.
Several of us landed and began walking towards the volcano. We sank deep in the soft pumice, which blistered our feet with its heat. I climbed painfully upwards toward the crater, in order to measure it with my sextant; but in a short time the heat melted the mercury off the mirror of the instrument. I was then half a mile from the crater.
As I was returning to the shore, I saw the bottom of each footstep I had made on my way up glowing red with the heat from beneath. We photographed the scene from the deck of the steamer, where the fire hose was kept playing constantly, wetting the rigging and everything about the ship to prevent her from taking fire.
