“ With marvelous agility it leaps over ravines, scales with nimble and sure feet the steepest acclivities, bounds along the narrowest paths on the edge of the most perilous abysses, and jumping from rock to rock, will take its stand on the sharpest point, where there appears hardly room for its feet to rest; and all this is accomplished with an accuracy of sight, a muscular energy, an elegance and precision of movement, and a self-possession which are without equal. From these facts, it can easily be understood that hunting this nimble and daring animal is an amusement full of danger. ”
