Doris danced up and down.

"Oh, I wish you would!" she cried. "I'd simply love to see the Arctic Circle!"

"So should I," said Cuthbert, and they were both so excited that they could hardly eat any tea. When Marian heard about it, she wished that she was pale too, and she wished it ever so much more the next morning when Captain Jeremy called on her father and mother and persuaded them to let Cuthbert go. Then he went to John Street and talked to Doris's mother, and he looked so commanding and yet so gentle that Doris's mother said she would be very glad to let Doris go with him to Port Jacobson.

"Of course, it'll be very cold," he said, "and they'll have to wear furs, but we can easily get those when we arrive, and all they'll want for the voyage is plenty of underclothing and their oldest clothes."

For a voyage like that, all among the ice, Captain Jeremy's sailing-ship wasn't quite suitable, so he had hired a little steamer with very thick sides, and a trusty pilot. Port Jacobson was in a sort of bay just under the shelter of Cape Fury, and beyond Cape Fury the coast had hardly been explored, it was all so bare and bleak and rocky. The only people who lived there were a few fishermen, a clergyman called Mr Smith, and a couple of engineers, who had been there for a year and had just found a coal-mine. It was the engineers who had written to Captain Jeremy, because they wanted him to bring them some machinery, and also because they wanted him to take back some of the coal that they had already dug up. That was how Captain Jeremy made his living, fetching and carrying things across the sea.

Neither Cuthbert nor Doris was the least bit sea-sick, and they loved to stand on the bridge beside Captain Jeremy and see the great billows rushing toward the steamer, one after another, in the bright sunshine. Sometimes they went below into the dark engine-room, where they had to shout to make themselves heard, and where the pistons of the engines slid to and fro like the arms of boxers that never got tired. How they loved the cabin, too, at meal-times, when the cook rolled in with the steaming dishes, and what meals they ate, in spite of the lurching table and the water slamming against the port-holes!

In a couple of days' time they had forgotten all about their tonsils, and two days after that they had almost forgotten their homes, and a week later they saw something in the distance like the grey ghost of a cathedral. It was an iceberg—the first that they had seen; but soon they began to see them every day, sometimes pale, in mournful groups, like broken statues in a cemetery, and sometimes sparkling in the sun as though they were crusted with a million diamonds.

One day they came on deck just after breakfast and saw miles and miles of ice, all jumbled together, and three hours later they saw a great cliff, covered with snow, standing out to sea. That was Cape Fury, and as they drew nearer they could see a little cluster of dark houses, with spires of smoke rising from their chimneys, and that was Port Jacobson. The pilot was on deck now, shouting all the time, and the steamer was going very slowly, with ice on each side of it, and they could see some men coming toward them, with rough-haired dogs pulling sledges. At last the steamer could get no farther, although it was still about a mile from the town, and they cast out anchors and a long cable that they began to carry toward the shore. It seemed very funny to Cuthbert and Doris to feel their feet again on something steady, even though this was only the rough surface of the frozen bay in front of the port. The days were so short here that the sun was already low, and the great cape stood dark and menacing, while far inland they could see the peaks of mountains slowly fading against the sky.

Among the men who had come to meet them were the two engineers and Mr Smith, and they were very surprised to see Cuthbert and Doris running about on the ice and trying to make snowballs. Then they all set off toward the little town, with the lights shining in its windows, and Mr Smith said that they must stay with him, because he and Mrs Smith had no children. Captain Jeremy was to stay with the two engineers, who had built a little house of their own, but they all came in to supper with the Smiths, and Cuthbert and Doris were allowed to sit up.

"To-morrow," said Mr Smith, "we'll get you some furs, and then you'll be able to go tobogganing with the other children," and Cuthbert and Doris said "Hooray!" because they had learned to toboggan on Fairbarrow Down. Just before they went to bed they saw a wonderful thing, for the whole of the sky began to quiver, and beautiful colours went dancing across it, melting away and then coming back again. These were the Northern Lights, or the Aurora Borealis, and Cuthbert and Doris could have watched them all night.
