2)From every hill slope came the trickle of running water, the music of unseen fountains. All things were thawing, bending, snapping. The Yukon was straining to break loose the ice that bound it down... Air-holes formed, fissures sprang and spread apart...

c)Buck refused to move under the rain of heavier blows which now fell upon him. Like his mates, he was barely able to get up. . . .

4) And then, suddenly, without warning, uttering a cry that was inarticulate and more like the cry of an animal, John Thornton sprang upon the man who wielded the club.
