A drive of two hours brought them to a rough saw-mill perched upon the edge of a water-fall at least fifteen hundred feet in height. Water-falls of this height are by no means rare in the Vesfjorddal, but the volume of water is usually small. This is not the case with the falls of the Rjukanfos however.
On reaching the saw-mill, Joel and Hulda both alighted.
"A half hour's walk will not be too much for you, will it, little sister?" asked Joel.
"No, brother; I am not tired, and a little exercise will do me good."
"It will be a good deal instead of a little, for you will have some pretty hard climbing to do."
"I can cling to your arm, Joel."
It was evident that the kariol must be abandoned at this point, for it would be impossible for it to make its way through the rough paths, the narrow passes, and over the big, fantastically shaped rocks that heralded the close proximity of the great falls.
Already, they could see in the distance a thick mist, the spray from the seething waters of Rjukan.
Hulda and Joel took a shady path which is well known to guides, and which leads to the end of the valley. A few moments afterward they found themselves upon a moss-covered rock almost in front of the fall. In fact there was no chance of getting any nearer to it on that side.
The brother and sister would have had considerable difficulty in making themselves heard if they had wished to speak; but their thoughts were those that could be exchanged without the agency of the lips.
