So far as New Hampshire is concerned, the treaty secures all that she requires, and New York and Vermont are quieted to the extent of their claim and occupation. The difference which would be made in the northern boundary of these two States by correcting the parallel of latitude may be seen on Tanner's maps (1836), new atlas, maps Nos. 6 and 9.

From the intersection of the forty-fifth degree of north latitude with the St. Lawrence and along that river and the lakes to the water communication between Lake Huron and Lake Superior the line was definitively agreed on by the commissioners of the two Governments under the sixth article of the treaty of Ghent; but between this last-mentioned point and the Lake of the Woods the commissioners acting under the seventh article of that treaty found several matters of disagreement, and therefore made no joint report to their respective Governments. The first of these was Sugar Island, or St. Georges Island, lying in St. Marys River, or the water communication between Lakes Huron and Superior. By the present treaty this island is embraced in the territories of the United States. Both from soil and position it is regarded as of much value.

Another matter of difference was the manner of extending the line from the point at which the commissioners arrived, north of Isle Royale, in Lake Superior, to the Lake of the Woods. The British commissioner insisted on proceeding to Fond du Lac, at the southwest angle of the lake, and thence by the river St. Louis to the Rainy Lake. The American commissioner supposed the true course to be to proceed by way of the Dog River. Attempts were made to compromise this difference, but without success. The details of these proceedings are found at length in the printed separate reports of the commissioners.

From the imperfect knowledge of this remote country at the date of the treaty of peace, some of the descriptions in that treaty do not harmonize with its natural features as now ascertained. "Long Lake" is nowhere to be found under that name. There is reason for supposing, however, that the sheet of water intended by that name is the estuary at the mouth of Pigeon River. The present treaty therefore adopts that estuary and river, and afterwards pursues the usual route across the height of land by the various portages and small lakes till the line reaches Rainy Lake, from which the commissioners agreed on the extension of it to its termination in the northwest angle of the Lake of the Woods. The region of country on and near the shore of the lake between Pigeon River on the north and Fond du Lac and the river St. Louis on the south and west, considered valuable as a mineral region, is thus included within the United States. It embraces a territory of 4,000,000 acres northward of the claim set up by the British commissioner under the treaty of Ghent. From the height of land at the head of Pigeon River westerly to the Rainy Lake the country is understood to be of little value, being described by surveyors and marked on the map as a region of rock and water.

From the northwest angle of the Lake of the Woods, which is found to be in latitude 45° 23' 55" north, existing treaties require the line to be run due south to its intersection with the forty-fifth parallel, and thence along that parallel to the Rocky Mountains.

After sundry informal communications with the British minister upon the subject of the claims of the two countries to territory west of the Rocky Mountains, so little probability was found to exist of coming to any agreement on that subject at present that it was not thought expedient to make it one of the subjects of formal negotiation to be entered upon between this Government and the British minister as part of his duties under his special mission.

By the treaty of 1783 the line of division along the rivers and lakes from the place where the forty-fifth parallel of north latitude strikes the St. Lawrence to the outlet of Lake Superior is invariably to be drawn through the middle of such waters, and not through the middle of their main channels. Such a line, if extended according to the literal terms of the treaty, would, it is obvious, occasionally intersect islands. The manner in which the commissioners of the two Governments dealt with this difficult subject may be seen in their reports. But where the line thus following the middle of the river or water course did not meet with islands, yet it was liable sometimes to leave the only practicable navigable channel altogether on one side. The treaty made no provision for the common use of the waters by the citizens and subjects of both countries.

It has happened, therefore, in a few instances that the use of the river in particular places would be greatly diminished to one party or the other if in fact there was not a choice in the use of channels and passages. Thus at the Long Sault, in the St. Lawrence—a dangerous passage, practicable only for boats—the only safe run is between the Long Sault Islands and Barnharts Island (all which belong to the United States) on one side and the American shore on the other. On the other hand, by far the best passage for vessels of any depth of water from Lake Erie into the Detroit River is between Bois Blanc, a British island, and the Canadian shore. So again, there are several channels or passages, of different degrees of facility and usefulness, between the several islands in the river St. Clair at or near its entry into the lake of that name. In these three cases the treaty provides that all the several passages and channels shall be free and open to the use of the citizens and subjects of both parties.

The treaty obligations subsisting between the two countries for the suppression of the African slave trade and the complaints made to this Government within the last three or four years, many of them but too well founded, of the visitation, seizure, and detention of American vessels on that coast by British cruisers could not but form a delicate and highly important part of the negotiations which have now been held.

The early and prominent part which the Government of the United States has taken for the abolition of this unlawful and inhuman traffic is well known. By the tenth article of the treaty of Ghent it is declared that the traffic in slaves is irreconcilable with the principles of humanity and justice, and that both His Majesty and the United States are desirous of continuing their efforts to promote its entire abolition; and it is thereby agreed that both the contracting parties shall use their best endeavors to accomplish so desirable an object. The Government of the United States has by law declared the African slave trade piracy, and at its suggestion other nations have made similar enactments. It has not been wanting in honest and zealous efforts, made in conformity with the wishes of the whole country, to accomplish the entire abolition of the traffic in slaves upon the African coast, but these efforts and those of other countries directed to the same end have proved to a considerable degree unsuccessful. Treaties are known to have been entered into some years ago between England and France by which the former power, which usually maintains a large naval force on the African station, was authorized to seize and bring in for adjudication vessels found engaged in the slave trade under the French flag.
