To carry out this idea, it would be desirable that there should be at each considerable seaport town, a sufficient garrison of _artillery_ troops to aid in the instruction of the volunteers.

In the present condition of the army _this_ cannot be hoped; but perhaps it might, at least, be found practicable to detail an artillery officer or two for the purpose." NOTE TO CHAPTER VIII .-- OUR NORTHERN FRONTIER DEFENCES.
The author has seen nothing since this chapter was written to induce him to change the views therein expressed with respect to the superior strategic importance of the line of Lake Champlain, both as a line of military operations, and as a line of defence.

The mutual commercial interests of the United States and the Canadas render a war between the two countries less probable than formerly; nevertheless, such an event is by no means impossible, and common prudence should induce us to prepare in the best possible manner for such a contingency.
NOTE TO CHAPTERS IX., X., XI.

AND XII .-- ARMY ORGANIZATION.
Since these chapters were written, several important changes have been made in our army organization.

The rank of Lieutenant-General (at least, by brevet) has been revived, the staff, administrative corps, infantry and cavalry have been increased, and a company of engineer troops organized.
