Part 16

Two or three miles in length of the line of highlands near the source of the river Du Loup require to be reexamined.

The longitudes of Lake Megantic, Lake Etchemin, the source of the Metjarmette, upon the line of Captain Talcott, and of some one point on the line of Professor Renwick ought to be ascertained with greater precision than the time that could be allowed during the last season would permit.

The instructions of Mr. Forsyth contemplated an exploration of the highlands described in the proclamation of 1763 as beginning on the north shore of the Bay of Chaleurs. The existence of a continuous elevated region from the tide of that bay to the termination of the exploring meridian line has been ascertained in a manner satisfactory to the commission, but the heights have not been measured on that part of it which lies nearest to the Bay of Chaleurs.

Under these circumstances the undersigned are of opinion that as no delay in the presentation of a final report will arise from further explorations of the parts of the territory thus pointed out and the more accurate examination of the uncertain matters, it would add to the confidence which may be placed in their results that a party be employed under the direction of each of the above-named commissioners upon the said work. For this object it is estimated--

1. That $25,000 in all, say $12,500 to be expended under the direction of each of the two above-named commissioners, will suffice. A less sum than this will not keep two parties in the field during the working season; a larger sum could not advantageously be expended on this part of the work.

2. In estimating the amount necessary for completing the delineation of the meridian of the source of the river St. Croix, it will be borne in mind that numerous astronomical observations must be made in aid of the operations with the transit instrument, in order constantly to preserve the true north direction, a condition of the utmost consequence, not alone as affecting the extent of territory that will be embraced by it, but more particularly because the character and position of the highlands alluded to in the treaty of 1783 would be exhibited in a very different light as encountered by a line running due north, as is required by the treaty, and by one varying even in a slight degree from that direction. This principle has already been exhibited in a striking manner by the trace of the meridian line as far as it has now progressed, for instead of encountering highlands in the latitude of Mars Hill having a claim to be considered those described in the treaty as the intended boundary between the two countries, the line as recently traced actually passes that latitude at an elevation of less than 10 feet above the level of the monument, and the greatest elevation encountered by this line in passing over any spur connected with Mars Hill is 63 feet above the level of the monument. In advance of this spur the line becomes again depressed below the level of the monument at several points before it reaches the Aroostook.

These, however, are only a few of the many facts that might be adduced from the surveys already made to show how important it is to the question at issue that every necessary means to avail of the aids of science should be adopted in order to preserve scrupulously the direction specified in the treaty while tracing this line. It must also be remembered that in the further prosecution of this duty a wilderness has to be traversed, totally uninhabited and totally without roads. The only means of progressing through it and of transporting the necessary provisions and the instruments indispensable to accuracy will be by means of canoes, for supplying two or three depots at points where Grand River and the waters of the Restigouche intersect the line, leaving the whole transportation along the meridian to be performed by packmen, or men carrying burdens on their backs. That the usual avenue to give an unimpeded view along the line must be opened through a dense forest, which in the neighborhood of all streams crossing it will still be found to consist of that swampy growth described in the report from the undersigned of the 4th of January instant as requiring so much labor to cut through it.

With all these circumstances in view, the following estimate for the completion of the survey of the meridian line and for some further surveys between that line and the source of the Aroostook is submitted; and it is intended to embrace the expense of completing both the field and the office wort that will require to be done in order to a final accomplishment of the duties:

Estimate for the meridian line.

1. Pay of 4 assistant engineers from May 1, 1842, to March 31, 1843, being 304 days, at $4 per day each $4,864.00

2. Pay of 3 other assistant engineers from May 1, 1842, to December 31, 1842, being 275 days, at $3 per day each 2,475.00

3. Hire of 30 men as axmen, and for preparing, constructing, and erecting stations and signals in advance, from June 1 to November 30, 1842, being 183 days, at $1 each per day 5,490.00

4. Hire of 30 other men as instrument carriers, chain bearers, canoe men, and packmen for 183 days, as above, at $1 per day each 5,490.00

5. Hire of 1 carpenter and 2 cooks 183 days, as above, at $1.25 per day each 686.25

6. Subsistence of 1 commissioner, 7 assistant engineers, 1 carpenter, 2 cooks, and 60 men, as above, being in all 71 persons, while in the field, 183 days at 50 cents per day each, including transportation of provisions to Grand Falls of St. John, or first depot 5,496.50

7. Purchase of barometers and repairs of instruments heretofore used 800.00

8. Salary of commissioner 3,000.00

9. Contingencies, including Stationery, office rent, and fuel, and transportation of engineers and commissioner to and from the field 1,500.00

Total required for the meridian line 30,801.75

That is to say, $30,801.75, making the whole amount for the work yet to be performed in the field on all parts of the boundary and for the office work that will be consequent from the said field work $55,801.75

All which is respectfully submitted.

JAS. RENWICK, A. TALCOTT, J.D. GRAHAM, Commissioners.

RECAPITULATION.

1. Amount of estimate for completing the surveys yet required to be made on the boundary, as above stated $55,801.75

2. Amount of estimate rendered with report of January 4, 1842, for completing maps of surveys already made, etc. 10,500.00

Aggregate amount required 66,301.75
