crosses to the east side, and remains, varying from 5 to 8 chains in distance, to near the termination of the line at the angle described in the original survey; being in the road, a little to the west of the carriage track.

The stone described in the original survey, as being marked with 'the letters C. R., was here found with the letters distinctly visible.

The surveys for this line were completed on the 12th of July, the party having been disbanded for three days in the interim.

SURVEY OF BYRAM RIVER. Before changing the location of the survey party, it was deemed advisable to make the surveys necessary to establish the line along the Byram river, from “ Lyon's Point” to the great stone at the wading place :) A minute and accurate survey was therefore made of the river, and a portion of the shore of the Sound to the eastward of the Point.

This survey was made upon the east or Connecticut side of the river, and covers a base line 203 chains in length, with about 100

detail, to which reference is made.

The proposed division line is fixed by monuments and reference points, established on the river bank, which points are designated by permanent marks easily identified.

This branch of service occupied the party until the 24th of July.

LINE RUNNING PARALLEL TO THE SOUND.

The party now resumed the survey of the line commencing at the angle at the “Duke's Trees," where the line from Byram river terminated.

In starting from this point it became necessary to rely somewhat upon the data furnished by the original survey in establishing a datum line, and it was determined to make the same angle from the established line as is shown by the magnetic bearing given of the two lines in the original survey. This gave a magnetic bearing for the line of north 66deg. east, which we adopted and traversed the line about 2 miles, when it was ascer- . tained that we were diverging considerably to the south of the traditionary marks of the State line, and it was therefore deemed advisable to change the bearing of the line.

This rendered it necessary to return to the “Duke's Trees " corner,and the bearing of the datum line was changed so as more nearly to approximate to the traditionary line, giving a magnetic bearing of north 66} deg. east.

The datum line thus adopted was laid on an offset of 2 chains and 35 links southerly of the angle at the “ Duke's Trees " for the purpose of avoiding the obstructions which intervened immediately on the line. The datum line was continued on this offset to its termination.

The country over which this line passes differs in character from that traversed by the line from the 6 wading place in Byram river” to the “Duke's trees." The latter follows more nearly up the water courses from the sound, and as a consequence encounters few irregularities of surface, while in the case of this line, it runs parallel with the sound and crosses the streams and ridges at right angles.

In this way the main branch of Byram river is crossed, near its head waters, at 75 chains, and “ Brundage's ridge” at 190 chains; descending “ Brundage's ridge” another branch of Byram river is crossed near the 240 th chain. The line immediately ascends another elevation, and passes over a rolling and somewhat broken surface, to the small village of Banksville near the 430th chain, where it crosses the Maharness riyer, which here runs northward, and reaches an elevated ridge, (McKay's,) bounding the valley of Maharness river, at the 575th chain. The traditionary line, at McKay's ridge, is some rods north of the datum line.

Maharness river is again crossed at the 656th chain. The valley on the east side, at the crossing, is bounded by a steep and almost inaccessible bank, rising to the height of 150 or 200 feet. Reaching this elevation the line passes over a rolling surface, to the small town of “Long Ridge,” at the 645th chain where the traditionary line is about 8 rods north of the datum line.

· Leaving Long Ridge the line passes through a swamp of considerable extent, (called in its vicinity “ Pool swamp,") and over

· a rough broken surface, of mostly unimproved land, to High

Ridge at the 805th chain. At this point the traditionary line was found to be 3 rods north of the datum line..

in the unimproved ground, back at the 720th chain, a heap of stones was found, 2 chains 40 links north of the datum line; but it is not sufficiently identified to justify the supposition that it is an original monument.

The surface is descending from High Ridge, and at the 850th chain the Dan Town river is crossed. Ascending another ridge of land, the line crosses a small stream near the 1010th chain, and a branch of the Norwalk river at the 1150th chain, and reaches the eastern extremity of the line at 1205 chains 34 links.

The surface passed over intermediate the streams, is rolling, considerably broken and but partially improved. On arriving at the east end of the line we found a monument, well described in the original survey, heing a heap of stones, 4 rods south of the terminus of the datum line; our datum line having crossed the traditionary line within the last mile. On a re-examination of the line, a monument was discovered near the 1065th chain, on what is called “Pudding Hill," near the highway and to the north of our datum line 2 chains.

The distance to this point from the west end of the line is 13.31 miles.

This correspondence in distance and a concidence of location with the description in the original papers, led to the supposition that this was the original monument set at 13 miles and 64 rods, being the terminus of the line, and the survey made in 1725.

If this supposition is correct, the commissioners, on resuming the survey in 1731, at this point, must have committed an error in getting the bearing of the line which was to be produced, making an angle of nearly one and a quarter degrees, which would sufficiently account for our datum line terminating to the northward of the monument at the terminus.

I understand the commissioners as inclining to the adoption of this supposition. A line so arranged would run in a direct line from the angle at the “ Duke's Trees" to this 13th mile monument, and then diverge to the east so as to terminate at the monument before described.

· This line would follow the traditionary line for two miles, commencing at the “ Duke's Trees,” where it diverges to the eastward and reaches its greatest eastward divergence at near the 5th mile, near Banksville, after which the two gradually approach and cross each other near the 8th mile, at “ Long Ridge ;" from this point the traditionary line continues to diverge to the eastward up to the 12th mile, when they again approach and terminate at a common point at the monument at near the 13th mile before described. From this monument the traditionary marks correspond very nearly with the line proposed to be adopted. The surveys on this line were completed on the 13th day of August.

LINE RUNNING NORTH-WESTERLY, TO THE ANGLE EASTERLY OF THE

HEAD OF LONG POND. From this monument, which is at the most easterly angle, the line bears northward nearly at right angles to the lines last surveyed.

Fixing a point in the traditionary line some distance ahead, on elevated ground, I adopted the range thus obtained as a datum

line.

Leaving the angle, the line passes over a broken surface and an intervening swamp, and crosses Mill river, a branch of the Norwalk, at near the 50th chain; it then ascends a ridge of considerable elevation, intersecting at the 75th chain the highway leading from Lockwood's mill to Ridgefield, along and near which it continues to near the 135th chain.

The surface from near the 90th chain, where the height of ground is attained after crossing Mill river, is quite uniform, although somewhat broken, to the 300th chain, and is mostly covered with timber from the 150th to the 250th chain. At the 300th chain it crosses a valley of considerable breadth, and reaches the high broken ridge to the east of South Salem, at the 360th chain.

The high broken land is mostly unimproved, and continues for about two miles, when the line descends to the low grounds laying easterly of the head of Long pond, and is terminated at the 538th chain, where we found the monument, supposed to have been erected in the original survey, 12 chains 38 links south of the datum line.

The monument at this angle is rather obscurely described in the original survey; but as this has been always recognised as the

angle, and no other monument has ever been known to have.. existed in this vicinity, there seems little room to doubt its identity.

Having determined the angle requisite to trace the corrected line back, it was re-surveyed, and points were designated at which it was deemed necessary to set monuments.

The line as established lies to the westward of the traditionary line as follows:

At the 91st chain, 2 chains 16 links ; at the 157th chain about 11 chains ; at the 570th chain, about 40 links.

No monuments were found on the traditionary line answering to the description given in the original survey.

The surveys on this line were completed on the 27th day of August.

LINE NORTHWARD TO THE INTERSECTION OF THE SOUTH LINE OF

MASSACHUSETTS. . . In establishing a datum line, or adopting a range which should approximate to the original line, great care was used, and the traditionary marks were examined, and search was made for the original monuments along the traditionary line, for about 10 miles ; a long range was thus obtained from the mountain near the south end of the line, over the traditionary line, to where it crosses “Round Mountain."

Finding that this range if taken in the direction of the monument, adopted as the south end of the line, would run at a considerable angle with the traditionary marks, and considering the monument as somewhat questionable in identity, I adopted a range which would the most nearly conform to the traditionary. marks as a datum line, and commenced the survey accordingly.

This datum line intersects the line established, at a point nearly 5 chains to the eastward, at right angles from the monument adopted as the angle.

Commencing the survey at this point, the line ascends a precipitous mountain, known as “Sarah Bishop's mountain,” and passes through a heap of stones near the 106th chain, which is supposed to be the first monument described as on this line, in the original survey; it is described as being located to the westward
