There is certainly no time to be lost. A single English steamer, flying the confederate flag, can pass the Cape, can coal at Mauritius, or rendezvous at Madagascar, and could then destroy more shipping than the whole fleet of pirates has yet done. It is at least probable that our national vessels would be refused permission to avail of Port Louis for repairs or supplies. It certainly does not comport with the honor of the nation to have to rely upon the churlish courtesy of England. Already, too, we see it announced that Napoleon will find in the massacre of French subjects a pretext to seize on the island. If our Government will spare a single one of the cruisers which have so uselessly sought the Alabama, it may, during the present year, negotiate a treaty which will at once advance our prosperity in peace, and increase our strength in any future war. It seems strange, indeed, that our statesmen cannot learn that we must hereafter abandon our isolated condition. England has taught us the folly of continuing indifferent to her aggressions in the East, in the hope that she will not interfere in the West. No blow can be more fatal to her supremacy abroad than the knowledge that we have secured a point where we perpetually threaten her line of communication with her colonies. We have written thus fully, because so few persons have had occasion to consider the subject. It seems probable, from the latest advices from Port Louis, that some envoy has visited the island, but what we require is a more imposing display of our power. The new queen, who has assumed the name of Rahoserina, is but a puppet in the hands of the council of nobles, of which Rainivoninahitriniony is the chief. Formerly all honors were held subject to the pleasure of the king, who could degrade his servants at pleasure; but this power is now declared to be abrogated. The powerful tribe of Saccalaves, always independent until the accession of Radama II, refuses to acknowledge his successor. It may be necessary to negotiate different treaties, perhaps, to protect American citizens in case of civil war. It is certainly most important to show the natives that we are really a great maritime nation. The time and position demand the employment of an able envoy, and the presence of such a naval force as may cause his mission to be respected.
