amation of 1763 and the commission
of Governor Wilmot.

12. As soon as the necessary instruments arrived from Metis at the river
Du Loup a party was detached to survey the Temiscouata portage, a line
known to be of great importance to the subsequent operations, but whose
interest has been increased from the unexpected frequency with which the
line dividing the waters touches or crosses it. Stores for a month's
service were transported with all possible dispatch to Lake Temiscouata,
along with the boats and camp equipage.

Two separate parties were now formed, the one to proceed up Temiscouata
Lake, the other to ascend the Tuladi. The embarkation of both was
completed at noon on the 4th September.

13. 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.

Mr. Lally had orders to enter and follow the river Asherbish, which
enters Lake Temiscouata at its head, until the progress of his boats
should be interrupted. The first party was directed to operate in the
first place toward the west, the second toward the east, upon the height
of land until they should meet each other's marks. 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 commissary was then moved up with a large
amount of stores and halted on the summit of Mount Biort, to be within
reach of both the parties in case of a demand for new supplies, and to
receive them on their return.

14. The party of Mr. H.B. Renwick, having passed through Tuladi Lake,
entered the main stream of that name on the 5th September. The head of
it had been seen by that gentleman in September, 1840, and held out the
promise of abundance of water for navigation. This promise did not
fail, but it was found that the stream had probably never before been
ascended, and was therefore embarrassed with driftwood. After cutting
through several rafts with great labor, a place was reached where the
stream spread out to a great width over beds of gravel, and all further
progress in boats became impossible. It was therefore determined to fall
down the stream a
