It is worthy of remark, that as military posts, all those lately established by the British are far superior, in point of situation, to those delivered up. The ground on which the new block house is building, on the British side of Niagara River, is nine feet higher than the top of the stone house in the American fort, and it commands every part of the fort. The chief strength of the old fort is on the land side; towards the water the works are very weak, and the whole might be battered down by a single twelve pounder judiciously planted on the British side of the river. At present it is not proposed to erect any other works on the British side of the river than the block house; but should a fort be constructed hereafter, it will be placed on Mississaguis Point, a still more advantageous situation than that on which the block house stands, as it completely commands the entrance into the river. The new post on Detroit River commands the channel much more effectually than the old fort in the town of Detroit; vessels cannot go up or down the river without passing within a very few yards of it. It is remarkable, indeed, that the French, when they first penetrated into this part of the country, fixed upon the spot chosen for this new fort, in preference to that where Detroit stands, and they had absolutely begun their fort and town, when the whole party was unhappily cut off by the Indians. [Sidenote: REMARKS.] The island of St. Joseph, in the third place, is a more eligible situation for a British military post than Michillimakinac, inasmuch as it commands the entrance of Lake Superior, whereas Michillimakinac only commands the entrance into Lake Michigan, which is wholly within the territory of the United States. It is sincerely to be hoped, however, that Great Britain and the United States may continue friends, and that we never may have occasion to view those posts on the frontiers in any other light than as convenient places for carrying on commerce. ------------------------------------------------------------------------ _LETTER _ XXXI. _Description of the River and Falls of Niagara and the Country bordering upon the Navigable Part of the River below the Falls._ Fort Chippeway, September.
