From the time the canoes take to go to Kabende I believe the southern shore to be a little into 12 deg.

of south latitude: the length, as inferred from canoes taking ten days to go from Mpabala to the Chambeze, I take to be 150 miles, probably more.

No one gave a shorter time than that.

The Luapula is an arm of the Lake for some twenty miles, and beyond that is never narrower than from 180 to 200 yards, generally much broader, and may be compared with the Thames at London Bridge: I think that I am considerably within the mark in setting down Bangweolo as 150 miles long by 80 broad.
When told that it contained four large islands, I imagined that these would considerably diminish the watery acreage of the whole, as is said to be the case with five islands in Ukerewe; but even the largest island, Chirubi, does not in the least dwarf the enormous mass of the water of Bangweolo.

A range of mountains, named Lokinga, extends from the south-east to the south-west: some small burns come down from them, but no river; this range joins the Kone, or Mokone range, west of Katanga, from which on one side rises the Lufira, and on the other the Liambai, or Zambesi.
