Sol-leks was limping, and Dub was suffering from a wrenched shoulder-blade.
They were all terribly footsore.

No spring or rebound was left in them.
Their feet fell heavily on the trail, jarring their bodies and doubling the fatigue of a day's travel.

There was nothing the matter with them except that they were dead tired.

It was not the dead-tiredness that comes through brief and excessive effort, from which recovery is a matter of hours; but it was the dead-tiredness that comes through the slow and prolonged strength drainage of months of toil.

There was no power of recuperation left, no reserve strength to call upon.
