"I razer zink I am," returned the philosopher with a faint smile; "mine onkle, I zink, is spraint."

This was indeed true, and it seemed as if the poor man's wanderings were to be, for a time at least, brought to an abrupt close. Fortunately it was found that a pony could be procured at that village, and, as they had entered the borders of the mountainous regions, and the roads were more open and passable than heretofore, it was resolved that the professor should ride until his ankle recovered.

We must now pass over a considerable portion of time and space, and convey the reader, by a forced march, to the crater of an active volcano. By that time Verkimier's ankle had recovered and the pony had been dismissed. The heavy luggage, with the porters, had been left in the low grounds, for the mountain they had scaled was over 10,000 feet above the sea-level. Only one native from the plain below accompanied them as guide, and three of their porters whose inquiring minds tempted them to make the ascent.

At about 10,000 feet the party reached what the natives called the dempo or edge of the volcano, whence they looked down into the sawah or ancient crater, which was a level space composed of brown soil surrounded by cliffs, and lying like the bottom of a cup 200 feet below them. It had a sulphurous odour, and was dotted here and there with clumps of heath and rhododendrons. In the centre of this was a cone which formed the true—or modern—crater. On scrambling up to the lip of the cone and looking down some 300 feet of precipitous rock they beheld what seemed to be a pure white lake set in a central basin of 200 feet in diameter. The surface of this lakelet smoked, and although it reflected every passing cloud as if it were a mirror, it was in reality a basin of hot mud, the surface of which was about thirty feet below its rim.

"You will soon see a change come over it," said the hermit, as the party gazed in silent admiration at the weird scene.

He had scarcely spoken, when the middle of the lake became intensely black and scored with dark streaks. This, though not quite obvious at first from the point where they stood, was caused by the slow formation of a great chasm in the centre of the seething lake of mud. The lake was sinking into its own throat. The blackness increased. Then a dull sullen roar was heard, and next moment the entire lake upheaved, not violently, but in a slow, majestic manner some hundreds of feet into the air, whence it fell back into its basin with an awful roar which reverberated and echoed from the rocky walls of the caldron like the singing of an angry sea. An immense volume of steam—the motive power which had blown up the lake—was at the same time liberated and dissipated in the air.

The wave-circles died away on the margin of the lake, and the placid, cloud-reflecting surface was restored until the geyser had gathered fresh force for another upheaval.

"Amazing!" exclaimed Nigel, who had gazed with feelings of awe at this curious exhibition of the tremendous internal forces with which the Creator has endowed the earth.

"Vonderful!" exclaimed the professor, whose astonishment was such, that his eyebrows rose high above the rim of his huge blue binoculars.

Moses, to whom such an exhibition of the powers of nature was familiar, was, we are sorry to say, not much impressed, if impressed at all! Indeed he scarcely noticed it, but watched, with intense teeth-and-gum disclosing satisfaction, the faces of two of the native porters who had never seen anything of the kind before, and whose terrified expressions suggested the probability of a precipitate flight when their trembling limbs became fit to resume duty.
