It was a great bull moose, a herd king, who forgot the example he owed to his weaker kindred and unloosed a thunderous bellow of terror which started the moose flight, the first memorable incident of the Winter of the Blue Snow. An overladen bough cracked above him; it fell and straddled him from quivering tail to flailing horns, burying him under its wet blue load. He reared out roaring, and his own herd echoed the cry; then a storm of moose bellows crashed through the forest. This tumult died, but there followed the earth-shaking thunder of a stampede. The bruins, awakened from their pleasant dreams, came out from their caves and blinked at the hosts of terrified moose which were galloping past. The earth-shaking uproar of the flight at last thoroughly aroused the bruins, and they began to sniff the air uneasily. Then they noticed the blue snow; and now in front of every cave crowds of bruins were staring down at the snow; and each bruin was swaying heavily, lifting his left front foot as he swayed to the right, and lifting his right front foot as he swayed to the left. The bruins had no courage either, and, once they had got sleep out of their heads, nearly all of them took out after the moose herds. The wind roared louder with every passing minute this night. And the flakes of the blue snow were as dense as the particles of a fog. At dawn a blue blizzard was raging. But the fauna of the forest plunged tirelessly on, seeking a refuge of white snow. And Niagara, made faithless by the Blue Terror, galloped behind them--Niagara, the great moose hound, bread-winner for the student of history, Paul Bunyon (his real name), and his companion also. Paul Bunyon lived at Tonnere Bay. He dwelt in a cave that was as large as ten Mammoth Caves and which had a roof loftier than any tower or spire. But this cave was none too vast for Paul Bunyon, the one man of this region, but one man as great as a city of ordinary men. His tarpaulins and blankets covered one-fourth of the cave floor; his hunting clothes, traps and seines filled another quarter; and the rest of the space was occupied by a fireplace and his papers and books.
