circumstance of this nature occurred in 1829 which brought these two parties in direct and open collision, and for a time involved the Consul of the United States in difficulties with the Government of Tripoli; the affair was originally of a private nature, but has ultimately produced the most serious changes in the situation of the Regency. It is well known that many efforts have been made during the last forty years, by individuals and by some European Governments, to obtain information respecting the interior of the African Continent; we are all familiar with the names and adventures of Ledyard, Parke, Burckhardt, Denham, Clapperton, Laing, Lander and others, whose labors have been important from the light thrown by them on the subject of their researches, and still more so as exhibiting instances of perseverance and moral courage with which the annals of warfare offer few parallels. Several of these heroic travellers took their departure from Tripoli, as the communications between that place and the regions which they desired to explore are comparatively easy and safe; and the Pasha, whether actuated by the expectation of obtaining some advantage from their discoveries, or by more laudable motives, appears from their accounts to have used every exertion to facilitate their movements. They likewise concur in expressing their gratitude and respect for Mohammed D'Ghies, who entertained them all hospitably in Tripoli and furnished them with letters of credit and introduction, which, says Denham, "were always duly honored throughout Northern Africa."
