Then we got them to bring us piles and stacks of dry wood; and we made an enormous bonfire in the middle of the main street. Round this, when they felt its warmth, the whole tribe gathered and smiled and wondered. It was a striking sight, one of the pictures from our voyages that I most frequently remember: that roaring jolly blaze beneath the black night sky, and all about it a vast ring of Indians, the firelight gleaming on bronze cheeks, white teeth and flashing eyes—a whole town trying to get warm, giggling and pushing like school-children. In a little, when we had got them more used to the handling of fire, the Doctor showed them how it could be taken into their houses if a hole were only made in the roof to let the smoke out. And before we turned in after that long, long, tiring day, we had fires going in every hut in the village. The poor people were so glad to get really warm again that we thought they’d never go to bed. Well on into the early hours of the morning the little town fairly buzzed with a great low murmur: the Popsipetels sitting up talking of their wonderful pale-faced visitor and this strange good thing he had brought with him—_fire_! _THE FOURTH CHAPTER_ WHAT MAKES AN ISLAND FLOAT VERY early in our experience of Popsipetel kindness we saw that if we were to get anything done at all, we would almost always have to do it secretly. The Doctor was so popular and loved by all that as soon as he showed his face at his door in the morning crowds of admirers, waiting patiently outside, flocked about him and followed him wherever he went. After his fire-making feat, this childlike people expected him, I think, to be continually doing magic; and they were determined not to miss a trick. It was only with great difficulty that we escaped from the crowd the first morning and set out with Long Arrow to explore the island at our leisure. In the interior we found that not only the plants and trees were suffering from the cold: the animal life was in even worse straits. Everywhere shivering birds were to be seen, their feathers all fluffed out, gathering together for flight to summer lands. And many lay dead upon the ground. Going down to the shore, we watched land-crabs in large numbers taking to the sea to find some better home. While away to the Southeast we could see many icebergs floating—a sign that we were now not far from the terrible region of the Antarctic. As we were looking out to sea, we noticed our friends the porpoises jumping through the waves. The Doctor hailed them and they came inshore. He asked them how far we were from the South Polar Continent. About a hundred miles, they told him. And then they asked why he wanted to know.
