Volcanic Eruptions of Mud and Salt
rocks, with a strong spray falling to leeward. The spot was completely surrounded by huts, for the manufacture of salt, and at a distance looked like a large village. Alighting, we went to the Bludugs, as the Javanese call them. They are situated in the village of Kuhoo, and by Europeans are called by that name. We found them to be on an elevated plain of mud , about two miles in circumference, in the centre of which immense bodies of salt mud were thrown up, to the height of from ten to fifteen feet, in the form of large globes, which, bursting, emitted volumes of dense white smoke. These large globes or bubbles, of which there were two, continued throwing up, and bursting seven or eight times in a minute At times they throw up two or three tons of mud. We got to leeward of the smoke, and found it to smell like the wash ing of a gun-barrel. "As the globes burst, they threw the mud out from the centre with a pretty loud noise, occasioned by the falling of the mud upon that which surrounded it, and of which the plain is composed. It was difficult and dangerous to approach the large globes or bubbles, as the ground was all a quagmire, except where the surface of the mud had become hardened by the sun; upon this we approached cautiously to within fifty yards of the largest bubble, or mud pudding, as it might very properly be called, for it was of the consistency of a custardpudding, and of very considerable diameter: here and there, where the foot accidentally rested on a spot not sufficiently hardened , it sunk, to the no small distress of the walker. "We also got close to a small globe or bubble, (the plain being full of them of different sizes,) and observed it closely for some time. It appeared to heave and swell, and when the internal air had raised it to some height, it burst, and fell down in concentric circles, in which shape it remained quiet until a sufficient quantity of air was again formed internally, to raise and burst another bubble. This continued at intervals from about one-half to two minutes. From various other parts of the quagmire round the large globes or bubbles, there were occasionally small quantities of mud shot up like rockets to the height of twenty or thirty feet, and accompanied by smoke. This was in parts where the mud was of too stiff a consistency to rise in globes or bubbles. The mud at all the places we came near was cold on the surface, but we were told it was warm beneath. The water which drains from the mud is collected by the Javanese, and by being exposed in the hollows of split bamboos to the rays of the sun, deposits crystals of salt. The salt thus made is reserved exclusively for the Emperor of Solo. In dry weather it yields thirty dudjins, of one hundred catties each, every month; but in wet or cloudy weather, less. "In the afternoon we rode to a place in a forest, called Ram sam, to view a salt lake, a mud hillock, and various boiling, or rather bubbling, pools. The lake was about half a mile in circumference, of a dirty looking water, boiling up all over in gurgling bodies, but more particularly in the centre , which appeared like a strong spring; the water was quite cold , and tasted bitter, salt, and sour, and had an offensive smell .
