APPENDIX I. 
Where the main branch, called by the Fulbe Mayo balleo, 
reaches the lake, at least during the rainy season, it divides 
into a net of smaller branches, thus increasing the difficulty of 
the navigation. On the contrary, the advantage of the smaller 
branch, the Bara-I'sa, or river of Bara, called by the Fulbe 
Mayo dhanneo, consists in preserving one unbroken volume of 
water. This was the reason probably why the party with 
whom Caillie went down the Niger from Jinni followed this 
branch. Besides the Mayo balleo and dhanneo, the chief 
creeks which join the Debu are the Mayo Piru and the 
Mayo Joga, not inconsiderable during the rainy season, but 
very small during the dry one. 
The lake, besides fish, contains numbers of that curious 
animal called ayu (majiatus).

branch of the river the following places : —
