The forty-six years of Zachariah Chandler's life in Michigan saw a vast material empire supplant an almost unbroken wilderness. His commercial enterprise and success and his labors as a legislator were among the influential agents in this marvelous development and give its story a title to a place in his biography. As early as 1634 Jesuits Brebuef, Daniel and Davost, following a route explored by Samuel Champlain eighteen years before, passed up the River Ottawa, across Lake Nipissing, down French river and along the lonely shores of the great Georgian bay to the dark forests bordering Lake Huron. Brebuef reached there first; Daniel came later, weary and worn; Davost came last of all, half dead with famine and fatigue.[2] Champlain had been before them, and other explorers preceded Champlain, but these three were the first Europeans who made a habitation by the shores of the great lakes which roll their tireless flood down through the gateway of Detroit. They erected a hut, and daily rang a bell to call the surrounding savages to prayers. Behind them was the tangled forest they had penetrated; at their feet were the broad waters of Lake Huron; beyond--toward the setting sun--was an abyss so soundless that no echo had ever come from it. And these three soldiers of the cross, converters of the heathen, unarmed and alone amid a multitude of savages, were the advance ripples of the mighty wave that two centuries later was to break across the lake at their feet and the rivers below them and surge over the trackless wilderness beyond. Seven years later (September, 1641,) Charles Raymbault and Isaac Jaques embarked in a frail birch-bark canoe, paddling northwest from Georgian bay among the countless islands of the St. Marie river, amid scenery that filled them with delight. After seventeen days the Sault de St. Marie burst upon their enraptured vision. There they were welcomed "as brothers" by the Chippewas and there began the first known white settlement in Michigan.
