OPERATIONS OF THE DIVISION UNDER THE DIRECTION OF JAMES RENWICK, LL.D.,
CHAIRMAN OF THE BOARD.

I.--_Operations during the year 1841_.

1. At as early a period as there was any probability of the country
being accessible two engineers were dispatched from the city of New York
for the purpose of exploring the Rimouski River. This had been crossed
by the commissioner late in the previous season. It had been ascertained
that it took its source much farther to the south than was represented
on any map, and that at its head would be the greatest difficulty in the
intended researches. It was, besides, considered necessary that skillful
boatmen and practiced woodsmen should be engaged in Canada. These it was
believed could be found in Quebec, and the chief of this detachment,
with an appointment as acting commissioner, was directed to perform this
duty on his route.

This detachment accordingly left New York on the 22d May. On reaching
Quebec it was found that the proper persons could only be engaged at
Trois Rivieres. A delay was thus occasioned before this part of the duty
could be performed. The detachment, however, reached Rimouski 4th June,
where the snow was still found upon the ground and the river barely fit
for the access of boats. No time had therefore been lost, and the
reconnoissance of the river was successfully performed. The detachment,
after passing all the establishments of lumberers, extended its
explorations beyond
