As for my uncle, he was beginning to storm against the horizontal road. He loved nothing better than a vertical path; but this way seemed indefinitely prolonged, and instead of sliding along the hypotenuse as we were now doing, he would willingly have dropped down the terrestrial radius. But there was no help for it, and as long as we were approaching the centre at all we felt that we must not complain.

From time to time, a steeper path appeared; our naiad then began to tumble before us with a hoarser murmur, and we went down with her to a greater depth.

On the whole, that day and the next we made considerable way horizontally, very little vertically.

On Friday evening, the 10th of July, according to our calculations, we were thirty leagues southeast of Reykjavík, and at a depth of two leagues and a half.

At our feet there now opened a frightful abyss. My uncle, however, was not to be daunted, and he clapped his hands at the steepness of the descent.
