This river was made the boundary between the territories of His Britannic Majesty and the United States, by the treaty of 1783 which describes the bounds as follows, viz. "That angle, which is formed by a line drawn due north from the source of the St. Croix river to the Highlands, along the said Highlands which divide those rivers that empty themselves into the river St. Lawrence from those which fall into the Atlantic Ocean to the northwesternmost head of Connecticut river; thence down along the middle of that river to the 45th degree of north latitude, from thence by a line due west on said latitude until it strikes the river Iroquois, or Cataraquy," &c.

The boundaries thus described, have caused considerable difficulty between the two Governments, in discovering which is the height of land mentioned in the treaty; and in regard to the St. Croix, it is supposed that the British Commissioners were totally unacquainted with the river in question, and not aware that the lines proposed, if run according to the American construction of the treaty, would separate the British Provinces of New -Brunswick and Canada. It is also probable that it was not precisely known at that time what river was meant by the St. Croix, but that another river, more to the westward, might have been intended. This uncertainty about the rivers at that time might have arisen from the general name of St. Croix, which was given by Europeans to all rivers falling into the Bay of Fundy, occasioned by the French on their first landing in the country, having erected crosses at different points, and named the places from that circumstance, the country of the Holy Cross. However it may have happened, difficulties ensured in ascertaining the precise Islands in the Bay of Passamaquoddy belonging to each power, and the Highlands meant by the treaty of 1783. This induced the Commissioners of the two Powers at the treaty of Ghent to provide against any misunderstanding on these points for the future, by the fourth and fifth articles of that treaty. The fifth article, bearing particularly on this point, states that "Whereas neither that point of the Highlands, lying due north from the source of the river St. Croix, designated in the former treaty of peace between the two powers, as the north-west angle of Nova-Scotia, nor the northwesternmost head of Connecticut river, have yet been ascertained; and whereas that part of the boundary line between the dominions of the two powers, which extends from the source of the river St. Croix, directly north to the above-mentioned north-west angle of Nova-Scotia, thence along the said Highlands which divide those rivers that empty themselves into the St. Lawrence, from those which fall into the Atlantic ocean to the north-westernmost head of Connecticut river, then down along the middle of that river to the 45th degree of north latitude, thence by a line due west on said latitude, until it strikes the river Iroquois or Cataraquy, has not yet been surveyed, it is agreed that for these several purposes two Commissioners shall be appointed, sworn, and authorized, to act exactly in the manner directed with respect to those mentioned in the next preceding article, unless otherwise specified in the present article. The said Commissioners shall meet at St. Andrews, in the Province of New-Brunswick, and shall have power to adjourn to such other place or places as they shall think fit. The said Commissioners shall have power to adjourn to such other place or places as they shall think fit. The said Commissioners shall have power to ascertain and determine the points above-mentioned, in conformity with the provisions of the said treaty of peace of 1783, and shall cause the boundaries aforesaid, from the source of the river St. Croix to the river Iroquois or Cataraquy to be surveyed and marked according to the said provisions: the Commissioners shall make a map of the said boundary, and annex to it a declaration under their hands and seals, certifying it to be the true map of the said boundary, and particularizing the latitude and longitude of the north-west angle of Nova-Scotia, of the north-westernmost head of Connecticut river, and of such other points of the said boundary as they may deem proper. And both parties agree to consider such map and declaration as finally and conclusively fixing the said boundary. And in the event of the said Commissioners differing, or both or either of them refusing, declining, or wilfully (sic) omitting to act, such reports, declarations, or statements shall be made by them, or either of them, and such reference to a friendly sovereign or state shall be made in all respects, as in the latter part of the fourth article is contained."-- The fourth article here alluded to provides that "such sovereign or state shall decide ex-parte upon the said report alone, and His Britannic Majesty and the Government of the United States engage to consider the decision of such friendly sovereign or state to be final and conclusive on all matters to them referred."-- Notwithstanding these precautions on the part of the Agents of the two Governments, the points alluded to are not yet ascertained or settled.

But to resume the description of the river. The St. Croix has two main branches, one inclines to the eastward (sic), and communicates with a chain of lakes, some of which are of considerable extent, and lie near a branch of the Penobscot river. The other turns to the westward (sic). From this branch there is a route by a succession of lakes and short portages to the waters that fall into the river St. John. The lands on the banks of this river are of good quality, and have been well timbered; most of the pine has been cut off, but there is still abundance of other timber, consisting of the harder woods, spruce, firs, &c. There are mills erected on different parts of this river, which furnish a great quantity of sawed lumber annually.

There are several falls in the river, which obstruct the navigation. There are, however, several find settlements along its banks, and the adjoining country is fast improving.

The frontier town of New-Brunswick, lies nearly opposite Robinstown (sic), in the State of Maine. It is a small pleasant seaport in the County of Charlotte: being situated near the river Saint Croix, on a narrow strip of low land fronting the Bay of Passamaquoddy, with a range of hills in the rear. It has two principal streets running parallel with the water, which are intersected by cross streets at right angles. The principal streets are well built up, and the town contains 2,268 inhabitants, according to the census taken in 1824.--It carries on a considerable trade in exporting squared and sawed lumber, and in shipbuilding- thirteen vessels were registered in the Port of Saint Andrews in 1824, amounting to three thousand six hundred and thirty-three tons, all of which had been built in the County, besides about five hundred and ninety tons, not included in the above amount.--It contains a neat Church belonging to the establishment, and a commodious Kirk, built at the sole expense of Mr. Christopher Scott, and presented by him to the members of the Kirk of Scotland. It has also a Grammar School, a Court House and Gaol; a Printing Office, with a number of find private buildings.

Here is likewise a Chamber of Commerce, a Savings' Bank, a Bible Society, an Agricultural and Emigrant Society of the County, with other public Institutions for promoting temporal and spiritual welfare of the inhabitants.

Saint Andrews being situated on the frontiers of the Province within view of the American territories, is a place of great importance in the event of a rupture with the United States. Considerable works were erected here during the last war, who are now much gone to decay. A few troops are, however, usually stationed here.--At the commencement of the last trouble with America, an agreement was wisely entered into between the Magistrates of this place, and the American authorities in its immediate vicinity, to abstain from mutual hostilities, which was strictly observed during the war, to the mutual advantage of both parties; who were thereby delivered from the horror of a predatory, murderous warfare, equally distressing to both nations.

Saint Andrews being the shire town of the important County of Charlotte, is silently rising in importance; and will no doubt, from its many natural advantages, always maintain its rank among the principal towns of this Province.

Section VI, Having in the preceding sections briefly described the five Counties lying along the river St. John; I shall now proceed with the three remaining, commencing with

This County is bounded by the Bay of Fundy on the south, by the St. Croix river, and the Bay of Passamaquoddy on the west and south west, on the east by a north line from Point Lepreau, and on the north by a west line commencing in the said north line thirty-three miles from Point Lepreau, and contains nine thousand two hundred and sixty-seven inhabitants.

It is divided from the United States by the river St. Croix, commonly called the Schoodick, which is the line in this quarter that divides the territories of His Britannic Majesty from the District (State) of Maine. It comprehends several large Islands in the Bay of Passamaquoddy, and is divided into the following Parishes:--St. Andrews, St. Stephens (sic), St. Davids (sic), St. Patricks (sic), St. Georges (sic), Pennfield, Campobello, West Isles and Grand Manan.

The Parish of St. Andrews, besides the town of that name already described, possesses many advantages for trade, being situated very conveniently for navigation. It has several Saw-Mills, and a great quantity of boards, planks, &c. are shipped from that port.

St. Stephens (sic) likewise furnishes vast quantities of sawed lumber. The mills in this parish on the river Schoodick are very numerous. More than four million feet of boards and planks are cut in this Parish annually. Ship-building is likewise carried on to considerable extent. Large quantities of shingles and small lumber of different descriptions are also furnished here for exportation. There is a Methodist Chapel with a stated Minister in this parish. The country is considerably improved, having several good farms. It has likewise a good herring fishery at the falls of the Schoodick.

St. Davids (sic) has likewise some good saw-mills. It also furnishes masts, and squared timber for shipping. The land in this Parish is of an excellent quality, and produces wheat, oats, indian corn, potatoes, &c. in great abundance.

The Parishes of St. Patricks (sic), St. George, and Pennfield, have each a number of saw-mills, and furnish large quantities of sawed lumber of the best quality--the country being well stocked with excellent pine. Considerable quantities of scale fish are also caught and cured here. Great improvements are likewise making an Agriculture in these Parishes, particularly in Pennfield, which producers wheat in great perfection. The settlers in this Parish are good farmers, and are making great improvements.

The Parishes of Campobello and Deer Island comprehend the Islands so called. Campobello includes the Islands on the south east side of Passamaquoddy river. It contains several thousand acres of land fit for cultivation. Many of the inhabitants are employed in the fishery along the shores. Great quantities of cod and other fish are taken about the Island, and sold uncured to the Americans. Formerly most of the gypsum exported from this Province was landed on this Island where it was shipped on board American vessels for Philadelphia and New-York.

Grand-Manan is likewise a considerable place for fishing, Ship-building, &c. and is of considerable importance in a nautical point of view, as it lies near the entrance of the Bay of Fundy. It is fourteen miles long and seven miles broad. The northernmost point is in latitude 44.54' longitude 66.45' west.

The rivers Maggagaudavick (sic) and Digdaguash (sic), lie in this county, and are of the utmost advantage in transporting the lumber from the interior. On each of these streams mills are erected. The Maggagaudavick runs a great distance into the country, and communicates with a chain of lakes, down which lumber is floated from a great distance. There are several falls in the Maggagaudavick-those near the mouth are nearly forty feet.

Several Islands lying in Passamaquoddy Bay, are within the limits of this county. Some of them are of considerable importance, on account of the fishery, and as affording harbors for shipping.
