The party having received its orders of recall, all the articles of equipment which could not be carried in the boats which had been launched on the waters of the Restigouche were transported to the other end of the portage and embarked in pirogues sent up Green River for that purpose under the direction of the assistant commissary. The engineers then set out on their return by the Bell Kedgwick, the Grande Fourche, and the Southwest Branch of Restigouche. Ascending the latter stream, this party reached the Wagansis portage on the 21st August, and arrived at the Grand Falls on the 25th August.

The descent of the Bell Kedgwick was attended with great difficulties in consequence of the low state of the waters. Until its junction with Katawamkedgwick, to form the Grande Fourche of Restigouche, it was necessary to drag the boats by hand.

10. The detailed map of the surveys of this division, exhibiting the more important points whose altitudes were determined by the barometer, has already been lodged in the Department of State under date of 27th December.

Although the interest of this survey to the United States has now passed away, yet, as it is probable that many years may elapse before this country shall be again explored, and as it may still possess some interest to the nation into whose undisputed possession it has now fallen, it may not be improper to state the methods employed in the survey, for the purpose of showing to what degree of faith it is entitled.

The latitude and longitude of the mouth of Green River were furnished by Major Graham. The three portages on that river were surveyed by chain and compass. The courses on the navigable parts of the river were taken with a compass and the distances measured by a micrometrical telescope by Ertil, of Munich. This instrument, which had given satisfactory results on Metis and Mistigougeche in 1841, was still more accurate in the present survey. The latitude of the south end of the Kedgwick portage as given by the plot of Green River on the original projection differed no more than 5" from that given by numerous astronomic observations, an agreement so close that it might be almost considered as arising from happy accident. This survey therefore required but little correction, which was applied from the observations already cited and from those at two intermediate points.

The survey of Kedgwick portage was performed with chain and compass. In the woods between the Bell Kedgwick and the boundary and along the whole line of survey the same method was used, observations for time and latitude being also taken whenever the weather permitted. As the lines intersected those of the last year, it can now be stated that every part of the boundary claimed by the United States, from the height of land on the Temiscouata portage which divides the waters of the Green River of the St. Lawrence from those of the St. Francis to the northwest angle of Nova Scotia, as well as its connections with the St. Lawrence and Lake Temiscouata by the Temiscouata portage, and with the St. Lawrence a second time by the Metis and Mistigougeche, and with the St. John by Green River, has been actually surveyed. This result is one that neither the Department in its original instructions nor the commissioner on his first view of the country had contemplated. In stating this the commissioner feels it his duty to acknowledge his obligations to the untiring zeal and energy of the gentlemen who have acted under his orders, and especially to his two first assistants, who, entering upon duties of an entirely novel character, not only to themselves, but to the country, have in the course of the operations of two years accumulated under the most disadvantageous circumstances a stock of observations which for number and accuracy may compare with those taken with every convenience at hand by the most practiced astronomers.

In addition to the latitude of numerous points determined astronomically by the party engaged in surveying the line through the woods, the latitude of a point near the southern end of Green River and Kedgwick has been determined by eighty-six altitudes of sun and stars taken with a repeating and reflecting circle.

The whole number of altitudes of sun and stars taken during the expedition for time and latitude was 806.

1. The operations of this division during the three seasons which it has been engaged in field duties have given a view of nearly every part of the country which has now been ceded to Great Britain to the north of the St. John River and the Temiscouata portage. During the year 1840 the commissioner proceeded in person by the wagansis of Grand River to the waters of the Bay of Chaleurs, ascended the Grande Fourche of the Restigouche to Lake Kedgwick, and then traversed the country from that lake to the Tuladi by a route never before explored. In 1841 the Rimouski and Metis were both ascended—the first to the limits of its navigation by canoes, the latter to the lake in which the waters of its western branch are first collected. From this lake lines of survey repeatedly crossing the boundary claimed by the United States were extended to a great distance in both directions. The operations of the year were closed by a survey of so much of the boundary as incloses the basin of Lake Temiscouata and intersects so frequently the great portage. These latter surveys covered in some degree the explorations of one of the parties in 1840, which, therefore, are not quoted as a part of the work of that year. In 1842 the valley of Green River was explored, that stream was carefully surveyed, and the remainder of the boundary line dividing the sources of Rimouski from those of Green River and the eastern branches of Tuladi run out with chain and compass.
