Ch. 11: How do the Black Riders track the travelers?

It seems the Riders have followed Sam ans Pippin's tracks.

'It is just as I feared,' he said, when he came back. 'Sam and Pippin have trampled the soft ground, and the marks are spoilt or confused. Rangers have been here lately. It is they who left the firewood behind. But there are also several newer tracks that were not made by Rangers. At least one set was made, only a day or two ago, by heavy boots. At least one. I cannot now be certain, but I think there were many booted feet.' He paused and stood in anxious thought.
