Notes on the Congo River . 167 
Macqueen, who to immense industry added many 
qualifications of a comparative geographer, recom¬ 
mended a careful examination of the estuaries 
between the Rio Formoso and Old Calabar. The 
question was not finally set at rest till 1830 
(November 15th), when Richard and John Lander 
entered Yoruba via Badagry and, triumphantly 
descending the lower Niger, made the sea by the 
“ Nun ” and Brass embouchures. 
Meanwhile, Mr. George Maxwell, a Scotchman 
who had long traded in the Congo, and who sub¬ 
sequently published a chart of the lower river 
proposed, at the end of the last century, to take 
from England six supernumerary boats for rowing 
and sailing, which could be carried by thirty people 
and portaged round the cataracts . This gave rise 
to Captain Tuckey’s first error, depending upon 
labour and provisions, which were not to be had 
“ for love or money ” anywhere on the Congo 
above the Yellala. With thirty or forty black 
rowers, probably Cabinda men, Maxwell advised 
navigating the river about May, when the Cacimbo 
or dry season begins ; and with arms, provisions, 
and merchandize he expected to reach the sources 
in six weeks. The scheme, which was rendered 
abortive by the continental war of 1793, had 
two remarkable results. It caused Mungo Park’s 
fatal second journey, and it led to the twin expe¬ 
ditions of Tuckey and Peddie.
