WVe have received letters...
AVe have receive(d letters from MIauritius, (fated the ,)6thl of June, the contents of wvhich possess considerable interest and importanec. Commodore INouRsg *vas at that islans, but was on the point of sailing for Bonmbetoc to incet RADAM, thC King of Madagascar, who ha(d left Ova, hlis capital, on the 9th of June, for that place, in company with Mr. HASTIE, the Goverinment agent ; the chiefs of Bombetoc having fully submitted to RAD)A3 S autho- rity. The progress of events in this loIig-neglected part of the world is gradiially opening proxpects of the most gra- tifying nature. Captaini Ovvi,, who comman(ds the sur- veying squadron in the Mozambique channel, had arrived at Mlauritius, having on board. his ship a chieftain from Mfombass, an islanid situate(d on the ceast of Africa, be- tween the 3d and tili degree of south latilutle, depute(d to offer that island, and the island of Pemba, in full sove- reignty to the Englisl. It appears that a few mnen have been stationedl by Cominodore OWEiN on Mombass, until orders can be received from England. This position is ani extremely favourable one for opposing a further check to the foreign slave-trade, as well as for the extelisioii of British commerce. It would, howvever, be highly imnpolitic i and unjust to take possession of it without the consent of our ally the Iniaun of MIuscat, of whose dominions they at presetit form a part. This Prince, it will he recolfected, was the first amnong the native Powers to enter into a treaty for the suppressioni of the slave-tradle with lhe British Governinent, which was con. cluded about? four years ago through the medium of Sir Ro- BERT FAnQ1IIA R, tilhen Governior ofMauritius The Imaum behaved on this occasion in thle inost magnanitnous and disinterested manner, cnterinig fully into tlhc enlightened views by whichi the treaty was dictated, and not requiring, like soine more civiliza(l Powers, to be bribed into an ob- servance of the laws of hunmanity. He even sacrificed on the occasion a very large revenue whicil he and his prede- cessors had been accustomed, time immemorial, to derive from this source. All the occurrences that have taken place in this part of the world tend imore and inore to the con- viction, that so long as t ae other European Powvers do not cordially co-operate with England in the abolition of the slave-trade, that scourgc can only be completely rooted out by going to the fountain oftthe evil, anid, by engaging the native Powvers on our side, destroyinig the markets for this infamous traffic. T'he strict observance of the treaty hitherto by the Imaum of NMuseat, wvho even allows his own ves- sels, if carrying slaves, to be captuired, shows that this has been effectually done on the eastern coa3t of Africa. There is little doubt thal the same system m2ay be pursued with equal effiect elsewhere; and experience proves that it may be done at one hundredth part of the expenses that have been) and continue. to be incurred by the present futile means employed for tlle accomplishment of that great object.
