“In the igloo,” said Nancy, “when we’re stewing with the dinner. Skating first, anyhow.”
Dorothea had been a little shy of skating with these Arctic explorers who knew all about ships and could signal in half a dozen different ways. She thought they would probably be as much better than Dick and her at skating as they seemed to be at everything else.
She and Dick sat together on some heather at the side of the tarn, fixed their skates on their boots and fastened the straps. She looked round. Everybody else was still busy with the screws. She fumbled with her straps, not wishing to be the first to start. But Dick had never a thought of the others who might be watching. The moment his skates were on he pushed himself off from his clump of heather, rose to standing height as he slid away, and was off. Every day of the holidays he had been with Dot on the indoor skating rink close by the University buildings at home, and this was a trick he had practised again and again, to start off from a sitting position instead of stepping awkwardly about before getting under way.
The Arctic explorers stared, open-mouthed.
“But he can skate,” said Titty.
“Like anything,” said Roger.
“Why didn’t you tell us?” said Nancy. “Of course, you ought to be in the Polar expedition. Not one of us can skate like that.”
“Golly!” said Peggy. “He can do it either way.”
Dorothea was now almost afraid they would think that Dick was showing off. But anybody could see that he had forgotten all about them and was simply skating for himself. He went flying up the little tarn, spun suddenly round and flew backwards, spun round once more, and came flying back to Dorothea.
“Come along, Dot,” he said. “This is lots better than doing it indoors.”
Titty and Roger were skating for the first time. John and Susan had had a little skating at school the winter before. But the Walkers lived mostly in the south, and year after year had gone by with never a patch of ice for them to skate on.
Nancy and Peggy were sturdy, straightforward skaters. Living in the north, at the foot of the great hills, they had had skating every year since they could remember anything, even though the big lake had frozen only once or twice. The smaller lakes and tarns were frozen every year. And at school, too, they had always had a few days when skating took the place of duller games. They could skate, but they knew enough about skating to know that skating was to Dick as natural and easy a thing as sailing their little Amazon was to them.
“You too?” said Nancy to Dorothea. But Dorothea did not hear her. She was already gliding off to join Dick, who had held out his hands to her. They crossed hands and went off together. Left, Right, Left, Right. Dick, in his methodical way, was keeping time aloud as he always did.
“They’re letting us be part of it,” said Dorothea, “because of your skating. Nancy’s just said so.”
“Part of what?” said Dick.
But they were turning now at the end of the tarn where a beck trickled in and warned them to keep their distance in case the ice might be weak near the running water. Nancy was coming to meet them. She was coming at a good pace, with a balancing jerk now and again, for this was her first day on the ice since last year, but anybody could see that she was putting her strength into it. She did not come swooping over the ice like a bird flying. And she knew it very well.
“Hi!” she called out. “You teach me how to twiddle round and go backwards and I’ll teach you signalling. You’ve got to learn anyhow.”
“You just put your weight on one foot and swing yourself round with the other,” said Dick. “At least that’s what it feels like.”
“Like this,” said Nancy, and swung herself round in the bravest manner while going at full speed, coming down with such a bump that if the ice had been a little less thick she must have gone through. But she picked herself up with a laugh. “Not quite like that,” she said. “Let’s have a shot at doing it slowly.”
John and Susan were on the ice now, moving with the earnest care of those who know how easy it is to fall. Roger, who had tried to copy Dick’s start, had sat down three times, quicker than it is possible to say so. He had pushed himself off, sat down, struggled up, sat down, struggled half up once more and come definitely to rest. Titty was standing on her skates but moving just an arm now and again when something happened to make her feel that even standing still was a fairly dangerous adventure.
“What did I do wrong?” Roger asked, sitting where he was. “I bet Susan’s put my skates on crooked.”
“Can I help?” Dorothea asked Titty.
“No. No. No. Don’t touch me,” said Titty. “I’m going to do it by myself.”
And a little later, John and Susan, skating solemnly by, met Titty almost half-way up the tarn, moving on one foot and kicking herself slowly along with the other. Roger was being pulled along by Dick. Peggy and Dorothea were skating together at the far end, while Captain Nancy, glancing rather nervously over her shoulder, was moving jerkily backwards with a fixed smile on her face.
But before long everybody, except Dick and Dorothea, who were already in practice, was more than ready for a rest. Skating uses muscles that seem to be mostly on holiday. There were aches in ankles and shin bones and hurried struggles towards the sides of the tarn where it was possible to ease the pain by sitting down for a minute or two on a clump of heather.
No time was wasted even while they were sitting about. Dick and Dorothea, who had been teaching Arctic explorers how to skate, became pupils once more. Some little flags on sticks had been brought up from Holly Howe and messages were flapped from one side of the tarn to the other, until when it was Roger’s turn he signalled “w-h-a-t-a-b-o-u-t-d-i-n-n-e-r” and Susan said it was high time to go and start the fire in the igloo. Nancy gave Dick and Dorothea their first lesson in flag-flapping and showed them how to make a short flap for a dot and a long sweep from side to side for a dash.
“But it’s no use until you know Morse,” she said. “You’ve simply got to learn it at once.”
“We will,” said Dorothea.
They took off their skates and went up the wood to the igloo for dinner, and while Susan and Peggy were dealing with the fire and boiling water for tea, Nancy wrote out the Morse alphabet for them twice over, once on the last page of one of the tiny note-books in which Dorothea was accustomed to write her romances, and once in Dick’s private pocket-book of scientific notes. Meanwhile, John was working away on the back of an envelope and had found that the two shapes, the square and the triangle, each of which could be hung up in two positions and either separately or together, made it possible to send twelve different messages. “We shan’t want more,” he said, “but if we do we can easily make another shape.”
It was agreed that the most likely signals were “Come to the igloo” and “Come to the tarn.” These were to be the diamond and the square. Then somebody suggested that there ought to be a “Yes” and a “No,” and it was decided that these had better be the north cone or cheerful triangle, looking up, and the south cone or melancholy triangle, looking down. Then diamond over north cone was to mean “Holly Howe.” Diamond over south cone was to mean
