Jan. 25th.--Started at 7 A.M. Course S.E.

Jan. 26th.--The Bohr tribe on the east bank. No wind. The current
nearly three miles per hour. The river about a hundred and twenty yards
wide in clear water. Marshes and flats, as usual. Thermometer throughout
the journey, at 6 A.M., 68 degrees Fahr., and at noon 86 to 93 degrees
Fahr.

Jan. 27th.--One day is a repetition of the preceding.

Jan. 28th.--Passed two bivouacs of the Aliab tribe, with great herds

Jan. 29th.--Passed a multitude of cattle and natives on a spot on the
right bank, in clouds of smoke as a "chasse des moustiques." They make
tumuli of dung, which are constantly on fire, fresh fuel being
continually added, to drive away the mosquitoes. Around these heaps the
cattle crowd in hundreds, living with the natives in the smoke. By
degrees the heaps of ashes become about eight feet high; they are then

themselves all over with the ashes, have a ghastly and devilish
appearance that is indescribable. The country is covered with old tumuli
formed in this manner. A camp may contain twenty or thirty such, in
addition to fresh heaps that are constantly burning. Fires of cow-dung
are also made on the leveled tops of the old heaps, and bundles of green
