The river could be as terrible as it was majestic; and then came the first touch of terror from the north, a tornado storm known as the "white wind." Whirling downward from a cloudless sky, its furious force lashed the water into waves, filled the air with sand and gravel, and barely missed sinking the boats as they were rushed to the bank. There, standing in water to their waists, the voyageurs held fast to the ends of the boats until a brief lull made possible their discharging. For a night and a day the storm-bound travellers were thus imprisoned on a narrow ledge in wretched plight--without fire, drenched to the skin, unable to sleep, shivering under the biting northerly gale. Near their destination they had to run the fearful rapids of the Ramparts, the most dangerous of the many swift currents of the Mackenzie. Their skiffs flew with frightful velocity, plunging down descents that were falls in low stages of water and being helplessly whirled around and around. Three danger spots were passed under conditions that made the missionary hold his breath, while admiring the dexterity and composure of the Indian steersman. It seemed an interminable eight miles, this series of rapids walled in by the towering, precipitous Ramparts, with only two points of refuge in its inhospitable cliffs even for a canoe. Petitot soon made himself at home at the mission of Fort Good Hope, situated on the arctic circle. He found the Hare Indians alert, loquacious, companionable, warm-hearted, and childlike in their sympathies and feelings. Speaking of the free, happy Indian life he says: "How can such misery be combined with such contentment with their lot? How does the sweet pride of a free man inspire their abject nomadic life? Ask its secret from the bird which flies warbling from shrub to shrub, waving its swift wings, drying its rain-wet plumage in the sun, tranquilly sleeping on a twig, its head under its wing." Learning the Hare language, baptizing the babes and teaching the adults, he also put up buildings, cared for the sick, and in his garden raised potatoes and turnips under the arctic circle. But ever keeping alive that wandering spirit which had its influence in his choice for a missionary life, Petitot was not content. With his work well in hand he learned with sadness from some of his Indian flock of the wretched conditions under which the Eskimos of Liverpool Bay were living. Fired with his usual zeal for the wretched, untaught savages, and perchance impelled somewhat by a desire to explore the country to the north, Petitot decided to make a midwinter journey to the polar sea. The agent, Gaudet, pointed out the dangers of travel in winter when the cold was excessive, sometimes ninety degrees or more below freezing, but when the priest insisted he accompanied him to Fort Anderson (or Eskimo) both men following on snow-shoes the dog-team that hauled their camp outfit over the two hundred and fifty miles of snow-covered country.
