wondered at the strange beasts, admiring their gaudy markings as he came closer to them. Upon the edge of the herd nearest him a plump stallion stood switching his tail against the annoying flies, occasionally raising his head from his feeding to search the horizon for signs of danger, sniffing the air for the tell-tale scent of an enemy. It was he that Nu selected for his prey. Stealthily the cave man crept through the tall grass, scarce a blade moving to the sinuous advance of his sleek body. Within fifty feet of the zebra Nu stopped, for the stallion was giving evidence of restlessness, as though sensing intuitively the near approach of a foe he could neither see, nor hear, nor smell. The man, still prone upon his belly, drew his spear into the throwing grasp.

It would be best thought Nu to retreat to the safety of the forest until he could ascertain the number and kind of beings that were approaching, and so, taking but careless advantage of the handier shelter, the cave man sauntered toward the forest, for now he was not stalking game, and never yet had he shown fear in the presence of an enemy. If their numbers were too great for him to cope with single handed he would not show himself; but none might ever
