6.  Green River has a fall and rapids near its junction with the St. John, which are passed by a portage of 1-1/2 miles.  At 15 miles from its mouth is a second fall, which is passed by a portage of 82 yards.  The stream for this distance and for 5 miles above the second fall is very rapid, its bed being in some reaches almost filled with rocks.  For the next 10 miles it has deep still reaches, alternating with gravel beds, or else the river flows over ledges of rock.  It is then interrupted by a third fall, requiring a portage of 176 yards.  Thence to the second fork of the lakes it has the same character as for the last 10 miles, except that in some places it flows with a gentle current between low banks covered with alder.  From the second fork of the lakes to the southern end of the Green River and Kedgwick portage the stream is very narrow and may be styled one continuous rapid.  It is upon the whole the most difficult of navigation of all the streams running into the St. John from its northern side, and approaches in its character of a torrent to the waters on the St. Lawrence side of the highlands.

7.  The portage from Green River to the South Branch of Kedgwick is 5-1/4 miles in length, and passes over the summits of two of the highest mountains in the ceded district, as well as several ridges.  No vessel heavier than a birch canoe had ever before been carried over it.  It therefore became necessary to clear it out before the bateaux and other heavy articles could be transported.  Fifteen extra laborers, who had been engaged, with their pirogues, to carry some of the stores from the St. John, were retained to aid in making this portage, which swelled the number to twenty-seven.  This large force was industriously engaged for eight days in carrying the stores and equipage over the portage, with the boats and canoes required for the future operations of the party.  In the meantime the portage was surveyed, and a great number of observations were made, by which the latitude of the southern end of the portage and its difference in longitude from that of the meridian line were determined with great accuracy.  In addition to the other labors of the party, a storehouse and observatory were erected.

8.  The commissioner, learning that the party had left the Grand Falls before his letter could have reached that place, addressed fresh orders to the engineer in command.  These were sent under cover to the British postmaster at Lake Temiscouata, who was requested to send them up Green River by an express.  By these he was directed to stop the progress of the party and to proceed himself to the river Du Loup, there to await fresh instructions.

These orders did not arrive in time to prevent the party intended for the survey of the boundary from setting out.  The engineer who had hitherto been in command returned to the St. John in pursuance of his original instructions and met the express on his way down Green River.  The commissioner, being advised on the 13th July that the treaty had been signed, immediately dispatched a special messenger, who joined the chief of the division at the mouth of Green River on the 24th July.  Measures were now taken for the recall and return of the party in the woods, and the whole division was assembled at the stationary camp at the north end of the portage on the 11th of August.
