Chap. XX. FREXCH EXPLORIXCt EXPEDITIOXS. 415 



The second expedition was a like failure ; it com- 

 menced exploring in July instead of waitiug imtil 

 November. Nevertheless it had a great advantage 

 over the first ; for it had a small steam tender besides 

 a larger steamer. The expedition went as far as the

 of the configuration of this part of Africa, I will 

 speak of the climate.

 the dry, as described in ' Equatorial Africa.' 



The rain begins in September and ends in May. 

 In 1864 a long dry season took place,. as I have said 

 in the course of this narrative, called enomo onguero;
