Legolas ran swiftly across the mountains for hours.

With that he sprang forth nimbly, and then Frodo noticed as if for the first time, though he had long known it, that the Elf had no boots, but wore only light shoes, as he always did, and his feet made little imprint in the snow.

‘Farewell!’ he said to Gandalf. ‘I go to find the Sun!’ Then swift as a runner over firm sand he shot away, and quickly overtaking the toiling men, with a wave of his hand he passed them, and sped into the distance, and vanished round the rocky turn.

The others waited huddled together, watching until Boromir and Aragorn dwindled into black specks in the whiteness. At length they too passed from sight. The time dragged on. The clouds lowered, and now a few flakes of snow came curling down again.

An hour, maybe, went by, though it seemed far longer, and then at last they saw Legolas coming back. At the same time Boromir and Aragorn reappeared round the bend far behind him and came labouring up the slope.

‘Well,’ cried Legolas as he ran up, ‘I have not brought the Sun. She is walking in the blue fields of the South, and a little wreath of snow on this Redhorn hillock troubles her not at all. But I have brought back a gleam of good hope for those who are doomed to go on feet. There is the greatest wind-drift of all just beyond the turn, and there our Strong Men were almost buried. They despaired, until I returned and told them that the drift was little wider than a wall. And on the other side the snow suddenly grows less, while further down it is no more than a white coverlet to cool a hobbit’s toes.’
