Note 49 — Chapter X · THE EAST AFRICAN EXPEDITION OF 1857-1859.

Mr Cooley (Geography, p. 29) informs us that the native porters start on their down journey ‘in March or April, probably at the end of the heavy rains, and return in September.’ He thus greatly restricts the period. Of course the season varies to some extent at every part; but, as a rule, to March and April add May and June, and for September read November and December. Dr Krapf is less incorrect (Travels, &c., p. 421); M. Guillain is equally so (vol. iii. 374).
