They sailed along in open order among the fishing boats, and yachts, and steamers. The nasty, rough ripple that had knocked down the little boy, and tried to steal his boat, had grown into a handsome big wave. Surger, they called him, because of his handsome head and fine flowing surge when he broke over the sand banks. He was very fond of Undine now, and kept close to her, as they sailed up the channel. It was a glorious day. The sun shone brightly, the gulls swooped down and floated for a few moments on Undine's shoulders, and then soared away down the breeze. The boats leaped merrily in front of them. "Shall we see any wrecks to-day?" asked Undine. "I hope so," shouted Surger; and he shook his curly white head, and shot in front of Undine, who could not help admiring his handsome presence. "Wrecks! Nonsense!" growled out old Lobster Pot from behind. "These are the holidays, and we are going to picnic up the river." Then they turned aside from the channel and went past a castle on a high rock, underneath steep cliffs, across wide mudbanks, lifting up the boats which were lying asleep among the damp seaweed. Some of the waves—lazy old fellows these—went off into the harbour for a quiet snooze, others ran up the river into long creeks, forcing their way roughly among the quiet country streams. Old Lobster Pot and his wife went straight along the big river. There Undine saw many strange sights. Trees and flowers, horses and carts, men, women, and children; but not one among them so beautiful, to her thinking, as the little blue-eyed boy she had tried to rescue from the naughty ripples. There, too, along the banks of the river, she saw wide, waving fields of green turning to gold, which rustled in the breeze, and she shouted to them to join her; for she felt so happy herself she wanted everyone else to be happy, too. But they did not understand her language, so they made no answer; for they were only wheatfields. At last they came to a big city, and ran between high walls of white stone, and saw tall buildings and the big towers of the cathedral, and here and there were crowds of people. "Oh! oh!" cried Undine and Surger together, "this is beautiful." The cathedral clock chimed four. Old Lobster Pot shook his head and called out the order for return. "Time is up," he said; "we must be moving down again now, or the river will be on to us." Surger laughed and cried out, "I will run another mile before I return, anyhow;" and he rushed up through the city with new force.
