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 and ascend the western branch, well known under the name of Abagusquash, and which had been fully explored in 1840.  The resolution to return was taken on the 6th, and on the evening of the 9th the beaver pond at the head of Abagusquash was reached; here a stationary camp was established.  One of the men had wounded himself with an ax and three more were so ill as to be unfit for service.  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.

15.  In the meantime Mr. Lally proceeded up Lake Temiscouata and entered the Asherbish.  This stream was also found very difficult, and on the evening of the 7th no more than 7 miles had been accomplished on it.  At this point a stationary camp was fixed and a detachment sent out to explore the neighborhood.  On the 10th Mr. Lally set out to the eastward, and struck the lower end of Abagusquash Lake on the afternoon of the 11th September.  Being obviously too far to the south, he ascended that stream and reached H.B.  Renwick’s camp on the evening of the 12th.  The next morning he proceeded to the height of land, and after twice crossing it reached his stationary camp on Asherbish at noon on the 21st September.

On this expedition two out of three barometers were broken, and an assistant was therefore sent to seek a fresh supply from the stores.

16.  The expedition sent out by H.B.  Renwick to the head of the Tuladi returned on the 13th September.  One of the men came in severely wounded, and those left sick and wounded in camp were still unfit for service; others also were taken sick.  Of the laborers of the party, one-half were thus lost for the present to the service.  The engineer in command, who had finished the observations for which he had remained in the stationary camp, determined, therefore, to proceed to Mount Biort in order to obtain men.  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
