One of the most frequent causes of difficulties between the Governments of Barbary and the Consuls of Foreign Powers, is the right claimed by the latter to protect all persons within the walls of their residence. In those countries it is absolutely requisite for the security of the Consul and for the discharge of his duties, that the persons in his employ should not be subjected to the despotism of the Government, nor to the doubtful decisions of the tribunals; and provisions to that effect are generally inserted in the treaties between Christian nations and those of Barbary. The Consuls however insist that the privilege should extend to the protection not only of their families, servants and countrymen, but also of all other persons under their roof; and the most abandoned criminals having entered such a sanctuary, are thus frequently screened from punishment. This privilege is productive of inconvenience not only to the Government but also to the Consuls whom it frequently involves in difficulties; the representatives of the inferior powers therefore seldom attempt to maintain it, but generally surrender the fugitive, if a native of the country, to the Government, or oblige him to quit their dwelling, rather than subject themselves to the hazard of having it invaded by force; those of Great Britain and France on the contrary, make it a point of honor not to yield, except in cases where the fugitive has injured some one of their colleagues or his guilt is clearly proved; and even then they have frequently required assurances that he should be pardoned, or that his punishment should be mitigated. A 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."

Hassuna and Mohammed D'Ghies the two sons of this respectable person, are also mentioned in terms of high commendation by many who visited Tripoli. Hassuna the elder was educated in France, and afterwards spent some time in England where he was much noticed in high circles, notwithstanding the assertion of the Quarterly Review to the contrary; on his return to his native country, he for some time conducted the affairs of his father's commercial house, and afterwards those of his ministerial office, in which he was distinguished for his attention to business and his apparent desire to advance the welfare of his country. Mohammed the younger son was brought up under the eye of his father at home; Captain Beechy of the British Navy who spent some time at Tripoli in 1822 while employed in surveying the adjacent coast, describes him as "an excellent young man," and as "an admirable example of true devotion to the religion of his country, united with the more extended and liberal feelings of Europeans. He daily visits the public school where young boys are taught to read the Koran, and superintends the charitable distribution of food which the bounty of his father provides for the poor who daily present themselves at his gate. Besides his acquaintance with English and French he is able to converse with the slaves of the family in several languages of the interior of Africa," &c. He was subsequently employed also in public affairs, and became the intimate confident of his brother-in-law the Bey Ali.

On the 17th of July 1825, Major Gordon Laing of the British Army a son-in-law of Consul Warrington, quitted Tripoli with the intention of penetrating if possible directly to Tombuctoo, and thence descending the river which is said to flow near that city, to its termination. He was amply supplied with letters by the D'Ghies family; and orders were sent to the governors and chiefs of places on his route, which were subject to the Pasha to aid him by every means in the prosecution of his journey, and to forward his letters and journals to Tripoli. For some time after his departure his communications were regularly received and bills drawn by him at various places were presented at Tripoli for payment. From these accounts it appears, that taking a south-western course he arrived on the 13th of September at Ghadamis a town of considerable trade situated in an oasis about five hundred miles from Tripoli; thence he passed to Einsalah in the country of the Tuaricks (a fierce race of wanderers) which he reached on the 3d of December and left on the 10th of January 1826. His journals up to this date were regularly received; from his few subsequent letters we learn that during the month of February, the caravan with which he travelled was suddenly attacked in the night by a band of Tuaricks, who had for some days accompanied them; many persons of the caravan were killed and the Major was dreadfully wounded, but he escaped and arrived at Tombuctoo on the 18th of August. At this place he had remained five weeks when Boubokar the Governor of the town who had previously treated him with favor, suddenly urged him to depart immediately, stating that he had received a letter from Bello the Sultan of the Foulahs a Prince of great power in the vicinity of Tombuctoo, expressing the strongest hostility to the stranger; Laing accordingly quitted Tombuctoo on the 22d of September, in company with Burbushi an Arab Sheik who had engaged to conduct him in safety to Arouan, distant about three hundred miles to the northward.

After this date nothing farther was heard from the traveller, no more of his bills were presented for payment at Tripoli, and Mr. Warrington becoming uneasy prevailed on the Pasha to have inquiries made respecting him. Messengers were accordingly despatched southward in various directions, one of whom on his return in the spring of 1827 brought an account that the Christian had been murdered soon after leaving Tombuctoo, by a party despatched from that place for the purpose. This statement was confirmed by all the other messengers on their return, and it was confidently repeated in a long article on the subject published in a Paris Journal, which gave the Prime Minister of Tripoli as authority. The other caravans and travellers however from the South contradicted these reports, and Hassuna D'Ghies on being questioned respecting the account driven in the Paris Journal, denied that he had supplied such information and asserted his total disbelief of the story. These and other circumstances induced Mr. Warrington to suspect that the Pasha or his Minister had for some interested motive suppressed Laing's communications; at his request therefore, the Commander of the British squadron in the Mediterranean sent a ship of war to Tripoli to give Yusuf notice that as the traveller had proceeded to the interior under his protection, he should hold him responsible for his safety, or at least for the delivery of his property and papers. This intimation was certainly of a most unreasonable character; the Pasha however could only exert himself to avert the threatened evil, by endeavoring to discover the traveller and at all events to disprove any unfair dealings or bad intentions on his own part with regard to him.

All doubts respecting the fate of the British traveller were however dispelled by the return to Tripoli of the servant who had accompanied him; from the statements of this man it was clearly ascertained, that the unfortunate Laing had been murdered in his sleep by his Arab conductor Burbushi on the third night after their departure from Tombuctoo, that is on the 25th of September 1826.

Some time after receiving this melancholy news, the British Consul was induced to believe that papers which were sent by his son-in-law from Tombuctoo, had actually arrived in Tripoli; and in the course of the investigations which he made in consequence, a suspicion was awakened in his mind that they had been secreted by Hassuna D'Ghies, in order to conceal some gross treachery or misconduct on his part. Under this impression Mr. Warrington urged the Pasha to have the papers secured, and not being satisfied with the means used for the purpose, he finally struck his flag, and declared that all official intercourse between himself and the Government of Tripoli, would be suspended until they were produced.

To avert the evils which might result from this measure, Yusuf labored diligently, and in the spring of 1829 he intercepted some letters sent from Ghadamis to Hassuna, which indicated a means of unravelling the mystery. Pursuing his inquiries farther, he became fully convinced of the perfidy of his Minister, and at length he declared to a friend of the British Consul, that two sealed packages sent by Laing from Tombuctoo, had been received by Hassuna and delivered by him to the French Consul in consideration of the abatement of forty per cent. in the amount of a large debt due by him to some French subjects. The fact of the receipt of the papers by Hassuna was to be proved by the evidence of the Courier who brought them from Ghadamis, and of other persons daily expected in Tripoli; the remainder of the Pasha's strange statement appears to have been founded entirely on a written deposition to that effect, of Mohammed D'Ghies the younger brother of the accused Minister, which was said to have been made in the presence of the Bey Ali and of Hadji Massen the Governor of the city.

On the strength of this declaration, Mr. Warrington insisted on the immediate apprehension of Hassuna, but he having received timely warning fled for refuge on the 20th of July, to the house of Mr. Coxe the American Consul; and immediately after to the surprise of all concerned, it was found that his brother Mohammed had likewise sought an asylum under the roof of Baron Rousseau.
