If his foothold upon a tiny ledge of rock failed him, or he was seized with dizziness, he was lost.
"We must save him!" said Hulda.
"Yes," replied Joel, "if we can keep our wits about us we shall perhaps be able to reach him." Joel gave a loud shout to attract the attention of the traveler, who immediately turned his head toward the spot from which the sound proceeded; then the worthy fellow devoted a few moments to deciding how he could best rescue the stranger from his dangerous position.
"You are not afraid, are you, Hulda ?" he asked.
"No, brother." "You know the Maristien well, do you not ?" "I have crossed it several times." "Then walk along the brow of the cliff, gradually getting as near the traveler as you possibly can; then allow yourself to slide down gently toward him, and take him by the hand, so as to prevent him from falling any further; but do not let him try to lift himself up, because if he should be seized with vertigo he would certainly drag you down with him, and you would both be lost." "And you, Joel ?" "While you are traversing the brow of the cliff I will creep along the edge of it on the river-side.

I shall reach him about as soon as you do, and if you should slip I shall perhaps be able to prevent you both from falling." Then, taking advantage of another interval in the roaring of the torrent, Joel shouted in stentorian tones: "Don't move, sir.

Wait; we will try to get to you!" Hulda had already disappeared behind the trees that crowned the ledge, in order to ascend the Maristien from the other side of the declivity, and Joel soon caught a glimpse of the fast-receding form of the brave girl at the turn in the path where the last trees grew.
He, in turn, at the peril of his life, had begun to creep slowly along the shelving edge of the ledge that surrounds the Rjukan.

What wonderful coolness, what steadiness of foot and of hand were required to thus advance in safety along the edge of an abyss whose borders were drenched with the spray of the cataract! In a parallel direction, but at least one hundred feet above his head, Hulda was advancing obliquely in order to reach the traveler more easily; but the position of the latter was such that she could not see his face, that being turned toward the cataract.
Joel, on reaching a spot directly below the unfortunate man paused, and after planting his foot firmly in a small crevice in the rock, called out: "Hallo, sir!" The traveler turned his head.
"Don't move, sir; don't move an inch, but hold fast!" "I'll do that, my friend, never fear," replied the stranger in a tone that reassured Joel.

"If I hadn't a good grip, I should have gone to the bottom of the Rjukan a quarter of an hour ago." "My sister is also coming to help you," continued Joel.
