It is believed that no foreigner was injured; but the nobles have taken an important step in proclaiming the new queen as direct successor of Ranavalo--thereby ignoring the reign of Radama II. As the fundamental rule of the Hovas had been that the title to all land was in the sovereign and inalienable, the grants to Lambert and others are held to be void. We believe this has not been officially stated, but Commodore Dupre, who negotiated the treaty between France and Radama, says that the treaty was almost unanimously rejected by the great council of nobles, and was accepted solely by the king. The last advices, 6th September, from Port Louis, are that the French fleet at Tamatave maintains a semi-warlike attitude toward the Hovas, not landing nor recognizing the authorities. Rumors are rife of the intentions of the French Government to seize Tamatave, and apply other coercive measures, unless the former treaty is carried into effect. The case seems to stand thus: The emperor, availing of the weakness of Radama II for his favorite Lambert, concluded a treaty, by which the king was to entirely alter the laws of the kingdom, and to give the French a controlling influence in the Indian Ocean. The people have deposed their ruler, and refuse to be bound by arrangements made by his will alone. Under ordinary circumstances, Napoleon would hardly brave the anger of England in a matter in which the latter has so much at stake. The prize, however, is well worth the effort. Any European nation obtaining sole possession of Madagascar dominates the East. It is surely time for our Government to awake to the importance of the steps now being taken. It is not a time when the interests of the country can be intrusted to the efforts of a consul or any inferior naval officer. We ought to send an envoy with powers to negotiate a treaty, and with such a fleet as will insure a respectful attention to our demands. The number of American vessels which frequent the coasts of Madagascar is a sufficient reason for us to interfere, without regard to the vastly greater interests which demand that this island shall not become a French colony. Our prediction that the confederate pirates would soon sweep the Indian Ocean of our richly laden India-men seems in a fair way to be accomplished; and where, save by the contemptuous forbearance of England and France, can our cruisers find a port for supplies, repairs, or information?
