After Great Britain had acknowledged the independence of the several States, if the true spirit of this treaty were not to be strictly adhered to, it must have been obvious at the time, that it would be impossible for her to defend her remaining North American possessions; much less be able at any future period to make them sufficiently powerful to cope with the United States. But surely with the Treaty, and the various documents alluded to by Mr. Waddilove, in their hands, a commission, composed of able military men, sent out to that part of the world, could so well define the boundary between the two countries, as to leave no further doubts upon the minds of our Government, as to the line of conduct to be with justice pursued towards the United States and also towards our North American possessions; and they would then be enabled also to act with that firmness and decision with which these republicans should be met in all our dealings with them. The idea of umpires ought not for a moment be tolerated—the treaty and the features of the country render them quite unnecessary. Without having any ambitious views, Great Britain evidently wants this disputed territory, if it were only for the security of her North American Provinces; and it might reasonably be expected that this point could be amicably arranged, if there is a sincere wish for peace, and any thing like good will towards us to be found in the United States. If therefore we are provoked to war, by simply working on both flanks of any body of troops hazarded by the States into the country alluded to, their fate may be pretty easily guessed or calculated upon; for we could have no difficulty in acting at once from Quebec, Halifax, &c.; and if hereafter emigration from the United Kingdom were duly and liberally encouraged, as it should be, into a country rightfully belonging to the British Empire, abounding in small lakes and fine rivers, we might soon begin to talk not only of our valuable but also of our powerful American colonies; especially if convicts, in place of being all sent to New Holland, were employed to make good roads to connect the countries lying between the Atlantic and the St. Lawrence. These convicts should never upon any account be allowed to become settlers.

Having so far entered upon the subject, I think I ought to proceed in what I hope may be useful; and whilst I speak from observations made upon the spot, I must take the liberty of reminding the reader that during the period occupied by "improvements" in the States; the Canadas, Nova Scotia, New Brunswick, &c., though somewhat retarded by late events, have not been standing still.

The country behind the line running from Lake St. Francis, to Lake Memphremagog, ought as soon as possible to be secured from sudden incursions, by a few respectable forts, or strong redoubts; capable of affording good cover for a certain number of cavalry and infantry; situations for which, upon or close to the present frontier, can be found, so that that entrance into Lower Canada may be covered. The line mentioned being taken as a base, and Isle aux Noix, Ash Island, and the part of the frontier extending along from the La Colle river towards Lake St. Francis being judiciously protected, the Lower Province would thus be secured from the inroads of brigands from the adjoining States; and if they, or if even an army should venture forward in that direction, it would not be quite easy for them to return; especially if the redoubts I speak of, are by the labour of soldiers made strong enough to require a week's regular siege for their capture, and which might be scientifically thrown up at no great expense. They should, however, be connected with each other by military roads; the making of which, as well as constructing the redoubts, would be excellent practice for the regular troops I am so anxious to have called out; who could never be better employed, (for habits of labour are essential to them,) than in works of this kind; and I hope I have already shown, that veterans are quite unfit for the duties of our North American frontiers.

The thick, in some places, almost impassable woods and swamps, extending often for a considerable distance along the frontier line of the Lower Province, render it difficult to make arrangements to oppose inroads from the States; for it is impossible to calculate upon the direction in which an enemy's force may make its appearance, and in order to watch all the roads or approaches, especially in winter, our troops must necessarily be too much scattered over the country; for owing to want of cover, they cannot be kept in sufficient bodies, but so far to the rear as to expose the advanced posts to be overpowered and cut off.

The following documents, which appear to be official, will show clearly, that I have not without good reason made the foregoing observations respecting the state of our affairs with the United States, and which call for energetic measures on our part.
