Fiercely we dragged at the fall of the fourfold tackle that formed the working end of the halliard, and at each pull the great, heavy, swaying yard slid a few inches up the short, thick mast, as though reluctantly, while away on our weather quarter we heard the fierce shouts of the men in the approaching boat as they encouraged each other, punctuated by the quick jerk of the oars in the rowlocks, and the swish of the water as the oar-blades clipped into it.  With the passage of every second those menacing sounds drew appreciably nearer, dominating even the thunderous rustle and slatting of the sail that slowly climbed into the air over our heads, while the felucca, now fast gathering stern-way, and at the same time paying off, was driving steadily down toward the boat at a rate that seemed to render our capture inevitable.
