Immediately after the war of 1812 a joint commission of our most distinguished military and naval officers was formed, to devise a system of defensive works, to be erected in time of peace for the security of the most important and the most exposed points on our sea-coast. It may be well here to point out, in very general terms, the positions and character of these works, mentioning only such as have been completed, or are now in course of construction, and such as are intended to be built as soon as Congress shall grant the requisite funds. There are other works projected for some future period, but as they do not belong to the class required for immediate, use, they will not be referred to.

MAINE.

Beginning at the northeastern extremity of our coast, we have, for Eastport and Wiscasset, projected works estimated to carry about fifty guns. Nothing has yet been done to these works.

Next Portland, with works carrying about forty or fifty guns, and Fort Penobscot and batteries, carrying about one hundred and fifty guns. These are only partly built.

NEW HAMPSHIRE.

Defences of Portsmouth and the vicinity, about two hundred guns. These works are also only partly built.

MASSACHUSETTS.

Projected works east of Boston, carrying about sixty guns. These are not yet commenced.

Works for defence of Boston Harbor carry about five hundred guns. These are nearly three-quarters completed. Those of New Bedford harbor carry fifty guns: not yet begun.

RHODE ISLAND.
