Quebec, Ontario, and Manitoba, as well as what is now the American Midwest and the Mississippi Valley), trading with First Nations as they went – guns, gunpowder, cloth, knives, and kettles for beaver furs. The fur trade kept the interest in France's overseas colonies alive, yet only encouraged a small colonial population, as minimal labour was required. The trade also discouraged the development of agriculture, the surest foundation of a colony in the New World. According to David L. Preston, after French colonisation with Champlain "the French were able to settle in the depopulated St. Lawrence Valley, not directly intruding on any Indian nation’s lands. This geographic and demographic fact presents a striking contrast to the British colonies’ histories: large numbers of immigrants coming to New England, New York, Pennsylvania, Virginia, and the Carolinas all stimulated destructive wars over land with their immediate Indian neighbors...Settlement patterns in New France also curtailed the kind of relentless and destructive expansion and land-grabbing that afflicted many British colonies." The Métis The Métis (from French métis – "mixed") are descendants of unions between Cree, Ojibwe, Algonquin, Saulteaux, Menominee and other First Nations in the 17th, 18th and 19th centuries and Europeans, mainly French. The Métis were historically the children of French fur traders and Nehiyaw women or, from unions of English or Scottish traders and Northern Dene women (Anglo-Métis). The Métis spoke or still speak either Métis French or a mixed language called Michif. Michif, Mechif or Métchif is a phonetic spelling of the Métis pronunciation of Métif, a variant of Métis. The Métis predominantly speak English, with French a strong second language, as well as numerous Aboriginal tongues. Métis French is best preserved in Canada, Michif in the United States, notably in the Turtle Mountain Indian Reservation of North Dakota, where Michif is the official language of the Métis that reside on this Chippewa reservation. The encouragement and use of Métis French and Michif is growing due to outreach within the five provincial Métis councils after at least a generation of steep decline. Canada's Indian and Northern Affairs define Métis to be those persons of mixed First Nation and European ancestry. Colonial wars Allied with the French, the first nations of the Wabanaki Confederacy of Acadia fought six colonial wars against the British and their native allies (See the French and Indian Wars, Father Rale's War and Father Le Loutre's War).
