Sorry, confused referent. He won't like it because the eagle isn't returning
from dropping Gandalf off in Lorien.
Because "they go with great speed for all that, and they do not tire. And later
we may have to search for our path in bare lands."
"They had come to the feet of sony hills, and their pace was slower, for the
trail was no longer easy to follow."
They spend a lot of time searching for the trail in the Emyn Muil and examining
the area around the dead orcs, making sure they don't miss any sign of the
hobbits. The orcs just move ahead; they know where they are going.
The orcs reach the East Wall in about 8 hours; it takes the Three Hunters
almost twice that, say 14
hours.
