I20 THE EXPLORATION OF THE NIGER waited in vain for letters from Abiddin, must have seemed very strange to the Tuaregs, who can have had no inkling of the reason. Moreover, a courier had come down in a canoe from Timbuktu to see us, and though I sent him away immediately, I felt sure that he had been seen.

At the same time, if we choose to go on he will watch over us, but towards the end his letter becomes almost threatening, for
