Some will tell you that you are mad, and nearly all will say, ‘What is the use?’ For we are a nation of shopkeepers, and no shopkeeper will look at research which will not promise him a financial return within a year. And so you will sledge nearly alone, but those with whom you sledge will not be shopkeepers: that is worth a good deal. If you march your Winter Journeys you will have your reward, so long as all you want is a penguin’s egg.
