Which quotation from “a horseman in the sky” shows how carter druze advances the plot of the story? “he could not hope to capture that enemy; to alarm him would but send him dashing to his camp with his fatal news.” “had he been awake, he would have commanded a view, not only of the short arm of the road and the jutting rock, but of the entire profile of the cliff below it.” “a touch upon the trigger and all would have been well with carter druse.” “duty had conquered; the spirit had said to the body: “peace, be still.” he fired.”
