"I will here remark, that however well my duties have made me acquainted with the greater part of the line in question, I have paid but slight attention to the forts and barracks erected by the British authorities near the borders of Maine, above Fredericton, in New Brunswick, or in Upper Canada, above Cornwall, being of the fixed opinion which need not here be developed, that all such structures would be of little or no military value to either of the parties in the event of a new war between the United States and Great Britain. "I was last summer at the foot of Lake Superior, and neither saw nor heard of any British fort or barrack on the St. Mary's River, the outlet of that lake. "Between Lakes Huron and Erie the British have three sets of barracks--one at Windsor, opposite to Detroit; one at Sandwich, a little lower down; and the third at Malden, 18 miles from the first; all built of sawed logs, strengthened by block-houses, loopholes, &c. Malden has been a military post, with slight defences. These have been recently strengthened. The works at Sandwich and Windsor have also, I think, been erected within the last six or eight months. "Near the mouth of the Niagara the British have two small forts--George and Messisanga. Both existed during the last war. The latter may be termed a permanent work. Slight barracks have been erected within the last two years on the same side, near the Falls, and at Chippawa, with breast works at the latter place; but nothing, I believe, above the works first named, on the Niagara, which can be termed a fort. "Since the commencement of the recent troubles in the Canadas, and (consequent thereupon) within our limits, Fort William Henry, at Kingston, and Fort Wellington (opposite Ogdensburg old works,) have both been strengthened within themselves, besides the addition of dependencies. These forts may be called permanent. "On the St. Lawrence, below Prescott, and confronting our territory, I know of no other military post; 12 miles above, at Brockville, there may be temporary barracks and breastworks. I know that of late Brockville has been a military station. "In the system of defences on the approaches to Montreal, the Isle Aux Noix, a few miles below our line, and in the outlet of Lake Champlain, stands at the head. This island contains within itself a system of permanent works of great strength. On them the British Government has, from time to time, since the peace of 1815, expended much skill and labour. "Odletown, near our line, on the western side of Lake Champlain, has been a station for a body of Canadian militia for two years, to guard the neighbourhood from refugee incendiarism from our side. I think that barracks have been erected there for the accommodation of those troops, and also at a station, with the like object, near Alburgh, in Vermont. "It is believed that there are no important British forts or extensive British barracks, on our borders, from Vermont to Maine.
