Autumn winds had long waved the grass in the vast upland valley and the breath of the north had tinged the meandering lines of trees along the river bottoms. Gold and purple, and a flame of fire, shone brightly in the morning sunlight. Birds and beasts of that wild open northland felt stir in them the instinct to move toward the south. The honk of wild geese floated down upon the solitudes and swift flocks of these heralds of winter sped by, sharply outlined against the blue sky.
