Letter from Mr. Cazneau in Reply to the Attack of the Evening Post.

TO THE EDITOR OF THE NEW YORK HERALD.

The Evening Post, in an article so maliciously and contemptibly false that it could not possibly be written by a gentleman, and to which no gentleman would condescend a written answer, accuses me of playing a very secondary part in what he calls the "St. Domingo intrigue." My whole course in the matter of a Dominican treaty, from the first moment of her revolution to and since annexation, will answer for me; nor did I ever speak or think of influencing any man's party or acting on any man's dictation.

By one accident, has happened one truth: I do feel a deep sympathy for the brave Dominicans, and I shall not be driven by the tricks of any anti-American clique, or partisan who prostitute their cause until the Dominican republic obtains its deserved and honored place in the family of free American States. I protest against the insolence of the Post in abandoning my principles whenever the popular tide sets against them, or fleeing my colors from newspaper warfare.

I could not descend to reply to the Post—for my way—but it is my duty as an American citizen to throw light on the subject of the Dominican treaty.

I charge the New York Evening Post with working—at standard prices—for His Imperial Majesty Faustin I., Emperor of Hayti, for the destruction of the white population of that island.

I charge it—in its capacity of organ and co-laborer of the imperial government of Faustin I.—with habitually garbling and suppressing the news from St. Domingo, for the purpose of keeping people from turning their attention and sympathy to that brave struggle of the Dominicans for liberty and self-government. It has aimed to sustain Hayti in its anti-American system for the exclusion of whites, and as such, has denied the right to carry into their territory an army of invasion for the purpose of destroying her sovereignty.

I charge it with asserting disgraceful ignorance or wilful falsehood, in asserting that the Dominican is not an independent state, and that there is not a negro in the Dominican territory, while the fact is that the number of pure black Haytien inhabitants in this small American State is smaller than of any other.

I charge it with attempting to deceive and mislead the American people by fabricating, under the form of Post editorials, the fabulous bulletins of Soulouque, written by his own tools; of glossing over the invasion of the Dominican republic in 1849; and of glossing over, and indirectly justifying, the burning of whole villages, and the indiscriminate slaughter of women, children, and even domestic animals, on his savage march. Faustin and the Post say he marched an army into the Spanish portion of the island, "with the intention of restoring the integrity of the republic." They suppress the history of Soulouque's humiliating defeat at Las Carracas, by a small force of Dominicans, and his retreat—or rather his covered retreat by stating that, "in consequence of the mutual distress of the troops, and the impossibility of getting food for his horses, he was obliged to return;" but "gave notice that he intended to renew hostilities the following year—1850"

The Post says, Mr. Pierce ought not to send Mr. Fillmore "to prevent Soulouque's executing his purpose of subduing Hispaniola to his government and territory," and is as indignant as his friend Faustin can be at Mr. Fillmore's threat to check these wholesale butcheries. It regrets that "this absurd pretension directly led to a second attempt by Soulouque with more respect than it deserved—for he did not make it until the Dominicans refused to give any pledges for the future;" and then this false organ of Hayti adds, "the President could not put it hard in so publishing the affair as to make it appear that the threats of the United States had any effect, for the simple reason that these things are taken from its own open and glorified in-structions to the French commander." This was a significant visit of one of the concern to Hayti! and the author of the article above quoted was sent to learn what reward for past service, or what pay for future exertion, was then arranged with Faustin.

Finally, I charge the Post with wilfully misrepresenting the Dominican government and people, in order to discourage the American government and people, in order to prevent a treaty between them... and turn it, if possible, into Haytien channels, to carry out their plan of Haytien policy, which is already enjoying the best of the St. Domingo trade, through secret pay with the Haytien government. This young, enlightened and pro-gressive people, with a debt of not a dollar in their treasury, has ably sustained its domestic government for ten years, and is as free to form alliance and make treaties with other nations as any nation on earth, and far more worthy of American sympathy.

I finally charge the Post with subterfuge in in-sinuating that the President is attempting by these in-trigues to frighten weaker children than itself—if it refers to the Dominican people as symptoms of new slave States and future annexations. I have had no interest, directly or indirectly, in the Dominican treaty, nothing to hide, deny or conceal in my plans, princi-ples or conduct.

Whatever I have done in the matter of Dominican independence, has been because I thought it right, necessary and beneficial to both countries; and while life lasts, my whole influence, so far as it extends, shall be used to preserve the white race from Haytien supremacy.

WILLIAM L. CAZNEAU.
