As he and his companions looked, they saw peeping through the foliage a black, fierce face, one of the ugliest and most ferocious that man could have imagined.  It was staring straight at them.  The brute's eyes were sunken under a heavy overhanging ridge of dusky skin.  His eyes were small and black, and the iris of each shone like a diamond set in carbon.  His forehead was low, receding, and covered with short bristling hair.  His nose was broad and flat.  His great jaw protruded frightfully, with the upper thin lip pressed tight, the lower curving away and displaying a row of long yellow tusks which could have bitten the hand off a man with one crunch.
