The expedition upon the bank of the river had been sent by the governor of Senegal. It consisted of two officers, Messrs. Dufraisse, lieutenant of marines, and Rodamel, naval ensign, and with these were a sergeant and seven soldiers. For two days they had been engaged in reconnoitring the most favorable situation for a post at Gouina, when they became witnesses of Dr. Ferguson's arrival.

The warm greetings and felicitations of which our travellers were the recipients may be imagined. The Frenchmen, and they alone, having had ocular proof of the accomplishment of the daring project, naturally became Dr. Ferguson's witnesses.

Here ended the astonishing journey of Dr. Ferguson and his brave companions, as vouched for by undeniable testimony; and they found themselves among friends in the midst of most hospitable tribes, whose relations with the French settlements are frequent and amicable.
