xiv’ LNTRODUCTION.: 
winter of 1821-22 was passed at Fort Resolution, on the south side of 
Great Slave Lake ; and the summer of 1822 was consumed in returning 
by. the route we had before travelled to York Factory, where we 
embarked for England in the month of September. The most 
interesting of the quadrupeds and birds collected on this Expe- 
dition were described by Joseph Sabine, Esq., in the Appendix to 
Sir John Franklin’s narrative, and I pubhsheth a list of the plants in 
the same work. 
. The Second or Last Norruern Lanp Exprpirion commenced, as far 
as regards the objects of natural history described in this work, at Pene- 
tanguishene, on St. George’s day, the 23d of April, 1825, and having 
performed a coasting voyage along the northern sides of Lakes Huron 
and Superior, arrived at Fort William, a post of the Hudson’s Bay 
Company, situated in Thunder Bay of the last-mentioned lake. From 
thence it ascended the Kamenistiguia to Dog Lake, and crossing a 
height of land of no great elevation at the source of the Dog River, 
and only between twenty and thirty miles from the shores of Lake 
Superior, it descended by a series of rocky rivers, interrupted by 
numerous cascades and portages, to Rainy Lake, the Lake of the 
Woods, and Lake Winipeg. On entering the Saskatchewan River, 
which falls into the last-mentioned lake, on its east side, the Second 
Expedition came upon the route of the first one already described, 
which it kept till its arrival at Fort Resolution, on Great Slave Lake. 
At Cumberland-house, Mr. Drummond, the Assistant Naturalist, was 
detached up the Saskatchewan to examine the plains of Carlton, and 
the eastern declivity of the Rocky Mountains, near the sources of 
the Peace River. ‘His labours will be more particularly mentioned. 
hereafter : at present I proceed to trace the progress of the Expedition, 
which, on its arrival at Fort Resolution, instead of directing its course 
across Great Slave Lake, as on the first journey, turned to the west- 
ward, along the south shore of the lake, and entered the Mackenzie, 
by far the largest of all the American rivers which fall into the Polar 
Sea, and which originating in the same elevated part of the Rocky.
