Frank Richardson Cana, 1911 Encyclopædia Britannica (1911)
“ Several of the Zambezi affluents are also navigable for many miles. The Lungwebungu, which enters the upper river, is navigable for a long distance, thus supplying communication with the extreme north-west corner of the Zambezi basin. Parts at least of the Luena, Kafukwe, Loangwa and the Kwando tributaries are also capable of being navigated. The possibility of connecting the Kwando with the navigable waters of the Okavango, at the point where the overflow mentioned below takes place, has likewise been suggested. ”
