184 EARL DE GREY'S ADDRESS. [May 28, 1860. 



Duveyrier to El Golea has justly earned the character of a daring 

 adventure, and the often-repeated offer of a prize has induced no 

 French traveller to hazard the dangerous route that is proposed to 

 bo followed by large caravans. 



An Arab, M. Ismael Bonderba, educated in France and attached 

 as interpreter to the " Bureau Arabe," has published an interesting 

 account in the ' Eevue Algerienno ' of his excursion from Algeria 

 to Ghat. To the south of Wargla he traversed the region of sand 

 and sand-hills termed El Edj, extending on one hand to the south 

 of Golea, and on the other to Ghadamis. This enterprising gentle- 

 man had already before this made a journey from Hed Suf to 

 Ghadamis in 1857. According to M. Bonderba's barometrical 

 observations, Mr. Ravenstein informs me that the elevation of 

 Laghnat is 2340 feet above the sea ; that the land falls thence to 

 the oasis of Wargla, and at Negussa the elevation is only 120 feet. 

 From Wargla to Ghat the land rises again, and it appears that the 

 drainage of this part, as far as the Jebel Koggur, is towards the 

 Sahara of Algeria, enabling the French to obtain a large supply of 

 water by means of artesian wells. The altitude of Ghat is 1830 feet, 

 or considerably more than has been assigned to it by Overweg. 



Some interest and probably no small degree of future importance 

 is connected with the geographical researches which have, within 

 the past year, been made by enterprising persons of African 

 race. 



Information has been received from the remarkable African re- 

 public of Liberia that the Messrs. Amos have returned from a tour 

 of observation to the Falls of the Sinoa Eiver, which place they 

 recommend as the site of a future mission. Mr. Miller had just 

 reached Monrovia from a tour to the Golah country, where also a 

 mission is contemplated. 



A much more considerable exploring expedition has been sent 

 out by the Liberians. It occupied at least six months, and appears 

 to have been ably performed by the Liberian travellers, Seymour 

 and Ash. Though making no pretensions to scientific acquire- 

 ments, they have furnished a very interesting narrative which is 

 continued through many numbers of the ' Liberia Herald.' 



They reached the city of Quanga, situated in a mountainous 

 region, a part of the Kong Mountains. Quanga is a large walled 

 town, 2500 paces in circumference, having five gates, from which 

 there are roads leading to other cities and towns. They state this 

 city to be 287 miles from Monrovia, 384 from Grand Bassa, a;icl
