During that period the following rivers and streams were surveyed: 1. The "main St. John River" from the mouth of the "Alleguash" to the Forks. 2. The "Southwest Branch" to its source at the Metjarmette portage. 3. The "South Branch," or "Wool-as-ta-qua-guam," to 5 miles above Bakers Lake and near to the exploring line of 1841 along the highlands claimed by Great Britain. 4. The "West Branch," or "Mat-ta-wa-quam," to its source in the highlands. 5. The "Northwest Branch" to its source in the highlands. 6. The "Big Black River," or "Chim-pas-a-ooc-ten," to its source. 7. The "Little Black River," or "Pas-a-ooc-ten." 8. The "Chim-mem-ti-cook River" as far as navigable. The character of all these streams is the same--slack water of moderate depth alternating with rapids. They can never be navigated by anything larger than a bateau. The method of survey was to trace the course of each stream by compass, estimating distances by the eye, or by pacing when the nature of the margin of the river would permit. The average distance coursed per day was about 9 miles, and at the camps formed at night astronomical observations north and south of the zenith were made to determine their position in latitude, and observations for the local time to ascertain their differences of longitude. Meridian observations of the sun were also made at a point intermediate to the camps whenever they could be obtained. Thirty-three of these points have been used in the correction of the paced and estimated distances. Tables exhibiting these observations, their calculation and results, will accompany the detailed maps. With a view to facilitate the operations of the joint commission it was conceived to be important that the intersection of the parallel of 46° 25' with the Southwest Branch should be ascertained, as also the point on the Northwest Branch (10 miles from the main St. John) where the boundary line from the outlet of Lake Pohenagamook intersects the said branch. It is believed that these points are projected on the map which accompanies this report so near to their true position that the line indicating the boundary as drawn on the map may be considered to substantially exhibit the division of territory as effected by the late treaty. The more thorough knowledge acquired through these explorations of the character of the territory which has been relinquished by the United States fully confirms the opinion previously entertained of its little value, either for its timber growth or for purposes of agriculture. Bordering on the "Big Black" and "Little Black" rivers the growth of pine is large and apparently of good quality, and it is believed that most of the smaller streams falling into the St. John below the "Seven Islands" will be found fringed with pine, but it is quite certain that very little will be found included between the lines of boundary and the highlands as claimed by the United States to the westward of St. Francis River.
