The king proclaimed freedom of religion, permitted the establishment of schools, established freedom of imports and exports, and granted lands to all bona fide settlers.

It was with the greatest surprise, therefore, that we have learned, some two months since, that a revolution has taken place, and that these fair prospects have been darkened by the murder of the king. It seems that he had made such lavish grants of land to his favorite, Lambert, that his nobles rebelled. Lambert had been sent to France to obtain the regalia for the coronation, and had organized a great company to hold these concessions. Whether the feuds of the missionaries, Protestant English and Catholic French, aided this, is not yet known.

It is clear, however, that the king and many of his personal friends were killed, and that his wife, Rabodo, is the queen. She is the sister of Ramboasalama, and probably represents the party of retrogression.

It is not, however, too late for our Government to recognize the ruler of Madagascar, and to obtain those indispensable advantages resulting. In time of peace, we shall have safe harbors for our merchant vessels, and we shall open a new field for our commerce. In time of war, we shall have these neutral ports as a refuge, and should diplomacy go one step farther and secure us a coaling station, we shall be on equal terms in the East with the other great maritime powers.

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.

Our last topic is to be considered. We do not advocate the establishment of costly works by Government, or the acquisition of a colony. The laws of commerce will provide the first, if only a proper protection is given to enterprise. Let us obtain but a single port under the safeguard of the American flag, and it will become a depot as flourishing as Singapore. Private enterprise will speedily establish dockyards and machine shops; for not only will there be an immense legitimate commerce with the Malagash, but the port will be the great centre for repairing and refitting our merchant vessels and whalers. The one thing needful, we repeat, is prompt action by our Government, with the certainty that the opportunity now presented will not return.

Note.—The latest advices from Madagascar, received via Mauritius, throw a little light upon the revolution which resulted in the death of Radama II. It seems probable that the late king had lost the esteem of his people by his partiality toward his favorites, by the concessions made to foreigners, especially to M. Lambert, and by his vacillating course in religious matters. His private life was such as to render it highly improbable that he had become a Christian; yet Mr. Ellis, the English missionary, exercised a great control over him.

The late queen was buried at Ambohimanga, a little village where there was a temple devoted to the chief idol. It seems that her son had promised to keep this spot sacred from the intrusion of the missionaries. Mr. Ellis most imprudently determined to preach there, and though driven away once, obtained troops from the king, and succeeded in a second attempt.
