FROM AMELIA ISLAND.
Extract of a letter to the Editor of the Charleston Courier, dated
"ST. MARY'S, OCT. 18.
"Annexed you will find a proclamation, which I have hastily copied for you. But, notwithstanding the language which it breathes, a revolution is still brewing; the American party is now waiting for Com. Champlain's arrival, when they will carry the day. At present every thing is in a state of suspense; no business doing; no prize sales have yet taken place, nor will, until this business is settled. The schooner Antelope, from Savannah, has just arrived here, and also a brig from New York with notions. This evening arrived a prize with slaves, which the U. S. brig Saranac has detained, as some have been smuggled. She has now 5 prizes here."

PROCLAMATION.
The Supreme Junta of the Floridas, to the inhabitants of Amelia.
A horrid plot has threatened to ruin, in its infancy, our rising republic. Discord, ever ready to spread its baneful alarms, had put us on the brink of a civil war; fortunately, we still preserved among us respect for liberty and the Cause we defended. We have discovered the secret machinations of a despotic government, and we have saved ourselves from ruin, into which Spanish perfidy was on the eve of plunging us.
Yes, citizens, the terrible blow that threatened us proceeded from the intrigues of our cowardly enemy; we have the most certain conviction of it. Only cast a look upon the promoters and leaders of the horrid scenes that have taken place. Is there amongst them one of the bravest, who so valiantly and so gloriously defended this place against forces ten times more numerous? No! the eye searches in vain for one of them. Wherever it perceives a leader, it beholds a person who abandoned you in the hour of danger; it beholds men who, guided by their own self interests, trifle with the shedding of the blood of the gallant defenders of liberty. Provided they accomplish their object, their views are accomplished. It is you, brave seamen, who have made so many sacrifices; it is your valor they wish to set forward for the perpetration of deeds so execrable. They create a huge phantom, when in reality it is but a chimera. What would have been the results had we unfortunately been compelled to come to extremities, and sent off those who, it is said, were to be sent off? By coming to extremities in a most cruel butchery. By sending them off, deprive this infant republic of the succor of valiant men, who have fought with you until now, and will never abandon you in the hour of danger. Had this happened, you, gallant seamen, would most assuredly have followed the route dictated by honor; but, weakened by it, you would have fallen a sacrifice to treachery and individual views; and the few remaining, whose valor would have sustained until the last, would have found themselves compelled to abandon this place, and fulfilled the wishes of our implacable enemies, who have no other means of destroying the germ of liberty, but dissention among its defenders. This would not have been the only evil; a greater one for yourselves would have ensued. Remorse, despair, would have attended your consciences to the grave, when cool reflection and calmness had told you, that you had stained your hands with the blood of patriots, who long defended the cause we have embraced—and that by Castilian intrigues.
Brave and gallant seamen! let us return thanks to that Divine Providence, which hovers and watches with a careful eye over this infant republic, for having saved us from the perpetration of such direful deeds: let us be united; and let this example, for the future, serve us as a lesson to be upon our guard against seduction.
By consent of the Council,
L. AURY,
Commander in Chief.
Fernandina, Oct. 4, 1817. 2d and 1st of Independence.
