In order to give the reader some idea of the tremendous violence with which nature sometimes distinguishes the operations of the volcano in these regions, and enable him to form some conjecture, from the occurrences of recent experience, of the effects they may have produced in past ages, a short account of the extraordinary and wide spread phenomena that accompanied the eruption of the Tomboro mountain, in the island of Sumbawa, in April 1815, may not be uninteresting. Almost every one is acquainted with the intermitting convulsions of Etna and Vesuvius, as they appear in the descriptions of the poet and the authentic accounts of the naturalist, but the most extraordinary of them can bear no comparison, in point of duration and force, with that of Tomboro. This eruption extended perceptible evidences of its existence over the whole of the Molucca Islands, over Java, a considerable portion of Celebes, Sumatra, and Borneo, to a circumference of a thousand statute miles from its centre, by tremulous motions, and the report of explosions; while within the range of its more immediate activity, embracing a space of three hundred miles around it, it produced the most astonishing effects, and excited the most alarming apprehensions. On Java, at the distance of three hundred miles, it seemed to be awfully present. The sky was overcast at noon-day with clouds of ashes, the sun was envelloped in an atmosphere, whose "palpable" density he was unable to penetrate; showers of ashes covered the houses, the streets, and the fields, to the depth of several inches; and amid this darkness explosions were heard at intervals, like the report of artillery or the noise of distant thunder. So fully did the resemblance of the noises to the report of cannon impress the minds of some officers, that from an apprehension of pirates on the coast vessels were dispatched to afford relief. Superstition, on the other hand, on the minds of the natives, was busily at work, and attributed the reports to an artillery of a different description to that of pirates. All conceived that the effects experienced might be caused by eruptions of some of the numerous volcanos on the island; but no one could have conjectured that the showers of ashes which darkened the air, and covered the ground of the eastern districts of Java, could have proceeded from a mountain in Sumbawa, at the distance of several hundred miles. Conceiving that it might be interesting and curious to preserve an authentic and detailed account of the information that could be gained of this wonderful phenomenon, while the event was still recent and fully remembered, I directed a circular to the different residents, requiring them to transmit to the Government a statement of the facts and circumstances connected with it, which occurred within their own knowledge. From their replies, the narrative drawn up by Mr. Assey, and printed in the ninth volume of the Botavian Transactions, was collected; the following is an extract from that paper.

"The first explosions were heard on this island (Java) in the evening of the 5th of April: they were noticed in every quarter, and continued at intervals until the following day. The noise was, in the first instance, universally attributed to distant cannon: so much so, that a detachment of troops was marched from Djocjocarta, under the apprehension that a neighbouring post had been attacked; and along the coast boats were in two instances dispatched in quest of supposed ships in distress. On the following morning, however, a slight fall of ashes removed all doubt as to the cause of the sound; and it is worthy of remark, that as the eruption continued, the sound appeared to be so close, that in each district it seemed near at hand, and was generally attributed to an eruption either from the mountains Merapi, Klut, or Bromo. From the 6th the sun became obscured; it had every where the appearance of being enveloped in a fog. The weather was sultry and the atmosphere close, and still the sun seemed shorn of its rays, and the general stillness and pressure of the atmosphere seemed to forebode an earthquake. This lasted several days. The explosions continued occasionally, but less violently, and less frequently than at first. Volcanic ashes also began to fall, but in small quantities, and so slightly as to be hardly perceptible in the western districts. This appearance of the atmosphere continued, with little variation, until the l0th of April; and till then it does not appear that the volcano attracted much observation, or was considered of greater importance than those which have occasionally burst forth in Java. But on the evening of the 10th, the eruptions were heard more loud and more frequent; from Cheribon eastward the air became darkened by the quantity of falling ashes; the sun was nearly darkened; and in some situations, particularly at Solo and Rembang, many said that they felt a tremulous motion of the earth. It was universally remarked in the more eastern districts, that the explosions were tremendous, continuing frequently during the 11th, and of such violence as to shake the houses perceptibly. An unusual thick darkness was remarked all the following night, and the greater part of the next day. At Solo candles were lighted at 4 p. m. of the 12th; at Mágelan in Kédu, objects could not be seen at three hundred yards distance. At Grésik, and other districts more eastward, it was dark as night in the greater part of the 12th April, and this saturated state of the atmosphere lessened as the cloud of ashes passed along and discharged itself on its way. Thus the ashes that were eight inches deep at Banyuwángi were but two in depth at Súmenap, and less in Grésik, and the sun does not seem to have been actually obscured in any district west of Semárang."

"All reports concur in stating, that so violent and extensive an eruption has not happened within the memory of the oldest inhabitant, nor within tradition. They speak of similar effects, in a lesser degree, when an eruption took place from the volcano of Karang Asam in Bali, about seven years ago, and it was at first supposed that this mountain was the seat of the eruption. The Balinese on Java attributed the event to a recent dispute between the two Rajahs of Bali Baliling, which terminated in the death of the younger Rajah by order of his brother."

"The haziness and heat of the atmosphere, and occasional fall of volcanic ashes, continued until the 14th, and in some parts of the island until the l7th of April. They were cleared away universally by a heavy fall of rain, after which the atmosphere became clear and more cool; and it would seem that this seasonable relief prevented much injury to the crops, and removed an appearance of epidemic disease which was beginning to prevail. This was especially the case at Batavia, where for two or three days preceding the rain, many persons were attacked with fever. As it was, however, no material injury was felt beyond the districts of Banyuwángi. The cultivators every where took precaution to shake off the ashes from the growing paddy as they fell, and the timely rain removed on apprehension very generally entertained, that insects would have been generated by the long continuance of the ashes at the root of the plant. In Rembang, where the rain did not fall till the 17th, and the ashes had been considerable, the crops were somewhat injured; but in Banyuwángi, the part of the island on which the cloud of ashes spent its force, the injury was more extensive. A large quantity of paddy was totally destroyed, and all the plantations more or less injured. One hundred and twenty-six horses and eighty-six head of cattle also perished, chiefly for want of forage, during a month from the time of the eruption."

"From Sumbawa to the part of Sumatra where the sound was noticed, is about nine hundred and seventy geographical miles in a direct line. From Sumbawa to Temate is a distance of about seven hundred and twenty miles. The distance also to which the cloud of ashes was carried, so quickly as to produce utter darkness, was clearly pointed out to have been the island of Celebes and the districts of Grésik on Java: the former is two hundred and seventeen nautical miles distant from the seat of the volcano; the latter, in a direct line, more than three hundred geographical miles."

The following is an extract from the reports of Lieutenant Owen Phillips, dated at Bima on the island of Sumhawa. "On my trip towards the western part of the island, I passed through nearly the whole of Dompo and a considerable part of Bima. The extreme misery to which the inhabitants have been reduced is shocking to behold. There were still on the road side the remains of several corpses, and the marks of where many others had been interred: the villages almost entirely deserted and the houses fallen down, the surviving inhabitants having dispersed in search of food. The Rajah of Sang'ir came to wait on me at Dompo, on the 3d instant. The suffering of the people there appears, from his account, to be still greater than in Dompo. The famine has been so severe that even one of his own daughters died from hunger. I presented him with three coyangs of rice in your name, for which he appeared most truly thankful."

"As the Rajah was himself a spectator of the late eruption, the following account which he gave me is perhaps more to be depended upon than any other I can possibly obtain. About 7 p. m. on the 10th of April, three distinct columns of flame burst forth near the top of the Tomboro mountain (all of them apparently within the verge of the crater), and after ascending separately to a very great height, their tops united in the air in a troubled confused manner. In a short time, the whole mountain next Sang'ir appeared like a body of liquid fire, extending itself in every direction. The fire and columns of flame continued to rage with unabated fury, until the darkness caused by the quantity of falling matter obscured it at about 8 p. m. Stones, at this time, fell very thick at Sang'ir; some of them as large as two fists, but generally not larger than walnuts. Between 9 and 10 p. m. ashes began to fall, and soon after a violent whirlwind ensued, which blew down nearly every house in the village of Sang'ir, carrying the ataps, or roofs, and light parts away with it. In the part of Sang'ir adjoining Tomboro its effects were much more violent, tearing up by the roots the largest trees and carrying them into the air, together with men, horses, cattle, and whatever else came within its influence. (This will account for the immense number of floating trees seen at sea). The sea rose nearly twelve feet higher than it had ever been known to do before, and completely spoiled the only small spots of rice land in Sang'ir, sweeping away houses and every thing within its reach. The whirlwind lasted about an hour. No explosions were heard till the whirlwind had ceased, at about 11 a. m. From midnight till the evening of the 11th, they continued without intermission; after that time their violence moderated, and they were only heard at intervals, but the explosions did not cease entirely until the 15th of July. Of the whole villages of Tomboro, Tempo, containing about forty inhabitants, is the only one remaining. In Pekáté no vestige of a house is left: twenty-six of the people, who were at Sumbawa at the time, are the whole of the population who have escaped. From the most particular inquiries I have been able to make, there were certainly not fewer than twelve thousand individuals in Tomboro and Pekáté at the time of the eruption, of whom only five or six survive. The trees and herbage of every description, along the whole of the north and west sides of the peninsula, have been completely destroyed, with the exception of a high point of land near the spot where the village of Tomboro stood."
