"You can if you like, but don't miss the train. If you turn up Cliff Street, exactly opposite the hospital, it will bring you straight to the station, and save your walking back here. Six o'clock, remember!" "Oh, thank you! There's heaps of time. Come, Gwethyn!" The Marsdens marched off with their guide-book, and easily found the old house in question, which was now used as an Alms Hospital for superannuated and disabled soldiers. They so dutifully curtailed their inspection of it, that Katrine declared they might safely go and look at the ruins of the city gate, which, according to her guide, must be quite close by. Whether the book was unreliable, or whether Katrine, in her haste, missed the right turning, is uncertain, but after wandering vainly round several streets the girls found themselves down by the bank of the river. "You said we had plenty of time, but you didn't look at your watch," panted Gwethyn. "If that clock over there is right, we shall never catch our train. Oh, you are a genius to-day! A prince of path-finders!" Katrine came to a sudden halt. Gwethyn's remarks were unpalatable, but strictly true. There were exactly ten minutes to spare. To go back to the station would require at least twenty. "It's the only train available by our excursion tickets," wailed Gwethyn. "I believe there's a later one about nine or ten o'clock, but they'll make us pay the difference between cheap bookings and ordinary fare." "I can see the glass roof of the station across the river, and there's a bridge in front of us. It's probably a short cut, and will save half the distance," announced Katrine hopefully. "Come along! Perhaps we can just do it!"
