Jules Verne,
Five Weeks in a Balloon — Chapter Thirty-Second…
(1873)
“ Since its arrival at Lake Tchad, the balloon had struck a current that edged it farther to the westward. A few clouds tempered the heat of the day, and, besides, a little air could be felt over this vast expanse of water; but about one o'clock, the Victoria, having slanted across this part of the lake, again advanced over the land for a space of seven or eight miles.The doctor, who was somewhat vexed at first at this turn of his course, no longer thought of complaining when he caught sight of the city of Kouka, the capital of Bornou. ”
