placed, bad as their state and position are, than the roads and railways. The Grand Trunk Railway is open to attack for many miles at different parts of its course, and in some places trains could be fired upon from American territory! Our reinforcements last winter were sent through New Brunswick and Nova Scotia, in sleighs, along a route which for miles could be cut across at any time by the enemy from Maine, and it would be necessary, to make all safe, for us to follow the Metapodliac road, or to construct the intercolonial railway. The harbours of Halifax and of St. John’s are not closed in winter, and the mode which was adopted of sending troops into Canada by those points would no doubt be reverted to till some better means shall be provided. From St. Andrew’s, in New Brunswick, there is a railroad to Woodstock, which lies near the state boundary of Maine. Here the route from St. John’s meets the St. Andrew road, and united the line follows the course of the St. John River, and may be divided into four days’ marches--to Florenceville, 1; to Tobique, 2; to Grand Falls, 3; to Little Falls, 4. All this route lies close to the American frontier, and is therefore quite unfit for the march of troops in detachments. The St. John’s route also takes four days to Woodstock. Even with the advantages afforded by the line of railroad, it must be remembered that the snows of winter may often mar all combinations;--our first detachments suffered considerably from cold in the railway carriages, and it may be readily conceived that the course of an army in sleighs to Rivière du Loup on the St. Lawrence, where the Grand Trunk Railway begins or terminates, might be rendered very unsafe by no more formidable agencies than violent snow-storms alone. Our military authorities do not, it is said, fear a winter campaign, but the Americans have already shown that they are not to be deterred by frost and snow from moving troops into Canada. To ensure moderate security the Metis road, notwithstanding its greater length, should be improved and adapted for military purposes, and the railway should be constructed to complete the work. In considering the three modes of invasion of which I shall speak, it may be inferred that Montreal will be the most likely point of attack, and that Quebec will be comparatively safe at first, but it would not be wise to act on the hypothesis as if it were an absolute certainty.
