There now came a brief lull in the warfare of the Lakes. The end of the War of the Palatinate was closely followed by Queen Anne’s War, but hostilities did not openly break out along the Inland Seas. The Treaty of Utrecht in 1713 left France technically in possession of the Lakes, but, even after this treaty, the English claimed as a sort of inheritance from the Iroquois the regions of Lake Ontario and Lake Erie. This fact again gave opportunity for plenty of excitement and trouble. The French had rebuilt Fort Frontenac and were establishing other strongholds, their object being to hem the English along their seacoast possessions by means of a string of forts extending from Canada southward. To frustrate these designs Governor Burnett, of New York, began the erection of a trading-post at Oswego in 1720. The French at once reciprocated by rebuilding Fort Niagara of stone, whereupon, in 1727, the English added a strong fort to their holdings in Oswego. This all but started active hostilities again. Beauharnois, the Governor of Canada, flew into a high dudgeon, sent a written demand for the English to abandon the fort, and threatened to demolish it unless this was done. The response of the English was to strengthen their garrison. Instead of carrying out his threat of war, Beauharnois began the strengthening of all the French forts, a work which continued for several years. Meanwhile the French trappers, traders, and priests of the Upper Lakes had been stirring the passions of the Indians against the encroaching English. The latter, in 1755, built two warships on Lake Ontario, and it was pointed out to the Western tribes that these were two of the terrible engines that were intended to work their destruction. By the time of the breaking out of the Seven Years’ War, the French, though their population was less than a tenth of that of their enemies, were splendidly prepared for war.
