Sylvius Hogg, who was now entirely well, took a long walk every day, and persuaded Hulda and her brother to accompany him.

One day all three of them went up the valley of Vesfjorddal half-way to the falls of the Rjukan.

The next day they went to Moel and Lake Tinn.

Once they were even absent twenty-four hours.

This time they prolonged their excursion to Bamble, where the professor made the acquaintance of Farmer Helmboe and his daughter Siegfrid.
