The map that is placed at the beginning of this chapter outlines the ambitious designs conceived by French statesmen soon after the Treaty of Aix-la-Chapelle. We see the names of many posts and forts intended to keep up communications between Canada and Louisiana, and overawe the English colonies then confined to a relatively narrow strip of territory on the Atlantic coast. Conscious of the mistake that they had made in giving up Acadia, the French now claimed that its "ancient limits" did not extend beyond the isthmus of Chignecto--in other words, included only Nova Scotia. Accordingly they proceeded to construct the forts of Gaspereau and Beausejour on that neck of land, and also one on the St. John River, so that they might control the land and sea approaches to Cape Breton from the St. Lawrence where Quebec, enthroned on her picturesque heights, and Montreal at the {222} confluence of the Ottawa and the St. Lawrence, held the keys to Canada. The approaches by the way of Lake Champlain and the Richelieu were defended by the fort of St. John near the northern extremity of the lake, and by the more formidable works known as Fort Frederick or Crown Point--to give the better known English name--on a peninsula at the narrows towards the south. The latter was the most advanced post of the French until they built Fort Ticonderoga or Carillon on a high, rocky promontory at the head of Lake Sacrement, afterwards called Lake George by General Johnson--a sheet of water always famed for its picturesque charms. At the foot of this lake, associated with so many memorable episodes in American history, General Johnson, a clever, ambitious Irishman, a nephew of Sir Peter Warren, in 1755, erected Fort William Henry, about fourteen miles from Fort Edward or Lyman, at the great carrying place on the upper waters of the Hudson. Returning to the St. Lawrence and the lakes, we find Fort Frontenac or Cataraqui at the eastern end of Lake Ontario, where the old city of Kingston now stands. Within the limits of the present city of Toronto, La Galissonniere built Fort Rouille as an attempt to control the trade of the Indians of the North, who were finding their way to the English fort at Choueguen (Oswego), which had been commenced with the consent of the Iroquois by Governor Burnet of New York and was now a menace to the French dominion of Lake Ontario. At the other extremity of this lake was Fort Niagara, the key to the West. {223}
