of a chief trader, was seen in good order, and far advanced on 
the way to Great Bear Lake, to build a house and lay in stores, 
and make other arrangements for his reception. Another part 
of his expedition, consisting of three light boats, manned by

Company. The crews of these boats will be employed, during 
the winter, in laying up provisions on Captain Franklin’s line of

Company has lately sent exploring parties into the northern

River, have intimated through a neighbouring tribe, their desire
