This line of settlements formed the frontier or line of outposts of civilization. On every side their frontagers were the Iroquois, or Indians of Five Nations, while right among them were the Mohawks. Only one English outpost faced Lake Ontario. This was the trading-station of Oswego. Here in 1722, the daring governor, William Burnet, aiming at the monopoly of the fur-trade, in defiance of the French, and in the face of the Seneca Indians’ protest, unfurled the British flag for the first time in the region of the Great Lakes. He built the timber lodge at his own expense, and encouraged bold young men, mostly from Albany and the valley settlements, to penetrate to Niagara and beyond. These commercial travellers—prototypes of the smart, well-dressed, and brainy drummers of to-day, and in no whit their inferiors in courage, address, and fertility of resource—went among the western Indians. They learned their language, and so opened the new routes of trade that within a twelvemonth from the unfurling of the British flag at Oswego there were seen at Albany the far-off lake tribes and even the Sioux of Dakota. Trade received such a tremendous stimulus that in 1727 Governor Burnet erected a regular fort at Oswego, where, in 1757, a French traveller found sixty or seventy cabins in which fur-traders lived. A promising settlement, begun by the Palatine Germans at Herkimer, was called Burnet’s Field, or, on the later powder-horn maps, Fort Harkiman. The fur-trade in our day calls for the slaughter annually of two hundred million land quadrupeds; drives men to ravage land and ocean, and even to rob the water animals of their skins; sends forty million peltries annually to London alone, and is still one of the great commercial activities of the world. It was relatively much greater in Johnson’s day; and to gain a master’s hand in it was already his ambition. It was the year 1738, the date of the birth of George III. of England, whom later he was to serve as his sovereign. Arriving in the nick of time, Johnson began at once the triple activities of settling his uncle’s acres with farmers, of opening a country store, and of clearing new land for himself. This latter was rapidly accomplished, Indian fashion, by girdling the trunks one year, thus quickly turning them into leafless timber, and planting either corn or potatoes the next season, in the now sunlighted and warm ground. Or the standing timber was cut down and by fire converted into potash, two tons to the acre, which was easily leached out, and was quickly salable in Europe. Corn or maize was the crop which above all others enabled the makers of America to hold their own and live; and corn was the grain most plentifully raised in the Mohawk Valley, though wheat was an early and steady crop. Corn meal is still sold in England as “Oswego flour,”—a name possibly invented by Johnson, who became a large exporter of grain and meal.
