Politically, however, the position of the English colonies was far from satisfactory. The French had discovered the mouth of the Saint Lawrence in the sixteenth century. From the region of the Great Lakes they had worked their way southward, had descended the Mississippi and had built several fortifications along the Gulf of Mexico. After a century of exploration, a line of sixty French forts cut off the English settlements along the Atlantic seaboard from the interior. [Illustration: THE FRENCH EXPLORE THE WEST] The English land grants, made to the different colonial companies had given them “all land from sea to sea.” This sounded well on paper, but in practice, British territory ended where the line of French fortifications began. To break through this barrier was possible but it took both men and money and caused a series of horrible border wars in which both sides murdered their white neighbours, with the help of the Indian tribes. [Illustration: THE BLOCKHOUSE IN THE WILDERNESS] As long as the Stuarts had ruled England there had been no danger of war with France. The Stuarts needed the Bourbons in their attempt to establish an autocratic form of government and to break the power of Parliament. But in 1689 the last of the Stuarts had disappeared from British soil and Dutch William, the great enemy of Louis XIV succeeded him. From that time on, until the Treaty of Paris of 1763, France and England fought for the possession of India and North America. During these wars, as I have said before, the English navies invariably beat the French. Cut off from her colonies, France lost most of her possessions, and when peace was declared, the entire North American continent had fallen into British hands and the great work of exploration of Cartier, Champlain, La Salle, Marquette and a score of others was lost to France.
