The Iroquois were an important branch of the great stock which included also the Hurons, or Wyandots, the native historical race of Canada. But divided as the two were throughout the whole period of French Canadian history by the bitterest antagonism, it is convenient to speak of them under the term of Huron-Iroquois. In reviewing the history of this indigenous stock, with the suggestions prompted by their peculiar characteristics, it is desirable not only to note the physical geography of the country which they occupied, as a region of forest and lakes, but, still more, to keep in view this fact as a predominant characteristic of the continent, and as one important factor in the evolution of whatever may seem to be peculiar in the forest tribes of North America. The effects resulting from the physical features of a country on the development and intermingling of its races can nowhere be wisely overlooked. Even within the limits of the British Islands the influences of mountain and lowlands: of the fertile stretches of Kent and the valley of the Thames, the fens of Lincolnshire, the moorlands of Northumbria, and the Welsh and Scottish Highlands, have largely contributed to the perpetuation, if not in some degree to the development, of ethnical distinctions and the diversities in language. In this respect Britain is an epitome of Europe, with its great mountain ranges and detached peninsulas, by means of which races have been isolated within well-defined areas, and their languages and other distinctive peculiarities preserved. Russia alone, of all European countries, presents analogies to Northern Asia as a region favourable to nomadic life; and in so far as its history differs from that of the continent at large, it accords with such physical conditions. Throughout the whole historic period, as doubtless in prehistoric times, the great chain of mountains reaching from the western spur of the Pyrenees to the Balkans has influenced European progress; while the chief navigable river, the Danube, traversing the continent through one uniform temperate zone, has tended still further to the perpetuation of certain distinctive ethnical characteristics in Central Europe. In all its most important geographical features, the northern continent of America presents a striking contrast to this. An isosceles triangle with its base within the Arctic circle, it tapers to a narrow isthmus towards the equator. Its great mountain chain runs from north to south, and in near proximity to the Pacific coast; and its chief navigable river, rising within the Canadian Dominion, and receiving as its tributaries rivers draining vast regions on either hand, traverses twenty degrees of latitude before it reaches the Gulf of Mexico. A lower range of highlands towards the Atlantic seaboard forms the eastern boundary of the great interior plain. But the Alleghanies or Appalachian system of mountains, though they may be said to extend from the St. Lawrence to
