Inquiry was carefully made for guides through the country between the sources of the Grande Fourche of Restigouche and of Tuladi, but none were to be found.

The party was now divided into four detachments, the first to proceed down the Restigouche to the tide of the Bay of Chaleurs, the second to ascend the Grande Fourche of Restigouche to its source, the third to be stationed on Green River Mountain, the fourth to convey the surplus stores and heavy baggage to Lake Temiscouata and thence to ascend the Tuladi and Abagusquash to the highest accessible point of the latter.

The stores, which were all that could be brought up in the state of the waters, were now found to be wholly insufficient to allow of committing the party to the unexplored country between this stream and Tuladi.

It was hoped that four or five days might suffice for the purpose, but ten of great toil and difficulty were spent before Lake Tuladi was reached.

The fourth detachment, after depositing the stores intended for the return of the party in charge of the British commissary at Fort Ingall, who politely undertook the care of them, ascended the Tuladi, and taking its northern branch reached Lake Abagusquash.

It found the source of the central or main branch of Tuladi to the north of that of the Abagusquash, and following the height of land reached the deep and narrow valley of the Rimouski at the point where, on the British maps, that stream is represented as issuing from a ridge of mountains far north of the line offered to the King of the Netherlands as the bounds of the American claim.

Nay, it was even concluded, although, as now appears, incorrectlyand it was not feared that the conclusion would weaken the American argumentthat the line from the northwest angle of Nova Scotia, at least as far as the sources of Tuladi, did pass through a country of that description.

Two separate parties were now formed, the one to proceed up Temiscouata Lake, the other to ascend the Tuladi.

Mr. H.B. Renwick, with the party under his command, was directed if possible to ascend the middle or main branch of Tuladi and form a stationary camp at the highest point of that stream which could be reached by boats.

The party of Mr. H.B. Renwick was directed, therefore, to proceed from the head of Tuladi and reach if possible the head of Rimouski, thus forming a connection with the line explored from the head of Mistigougeche; that of Mr. Lally to proceed from the head of Asherbish along the height of land to the Temiscouata portage.

The party of Mr. H.B. Renwick, having passed through Tuladi Lake, entered the main stream of that name on the 5th September.

The numbers were yet sufficient for short expeditions, and one was immediately fitted out for the head of Tuladi with provisions to form a cache for future operations.

This expedition explored so much of the height of land as would otherwise have been thrown out of the regular order in consequence of the failure to ascend the main branch of Tuladi.

The expedition sent out by H.B. Renwick to the head of the Tuladi returned on the 13th September.

Previous to his departure on the 15th September he fitted out a second expedition with all the disposable strength for the purpose of operating between the head of Tuladi and the point in the height of land where Mr. Lally's line diverged to the southwest.

The party of H.B. Renwick descended the Abagusquash and Tuladi, and, crossing Lake Temiscouata, reached the same rendezvous on the 5th October.

It has been seen that on the expedition up the Metis a seasoned voyageur had been worn out by the severity of his labors; on the Tuladi half the men were sick at a time; and of Mr. Rally's party two Penobscot Indians of herculean frame were compelled to return by extreme fatigue.

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 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.

The explorations of 1840, in which the ground lying between the western sources of Green River and Squattuck, a branch of Tuladi, was traversed, showed a considerable extent of better land than any other in the ceded territory.

There is still some timber on the waters of Squattuck, but it has been diminished by two or three years of active lumbering, while that around Tuladi, if it were ever abundant, has disappeared.
