Niger River, West Africa (Google Maps ⧉, OpenStreetMap ⧉)

"From the Niger banks, with successive waves of larger migrants, they have come hither to pitch their leafy huts in the unknown recesses of the forest."

"At sunset we arrived at Modiboo—a delightful village on the banks of the Niger, commanding a view of the river for many miles both to the east and west."

"‘Sometimes I had thoughts of swimming my horse across the Niger…’"

"…and as all that part of the country to the north of the Niger is destitute of rivers, whenever the pools in the woods are dried up the elephants approach towards the banks of that river."
