The Tripoline ambassador, before mentioned, thought that peace could be made with the three smaller powers for ninety thousand pounds sterling, to which were to be added the expenses of the mission and other incidental expenses. But he could not answer for Algiers; they would demand more. The ministers plenipotentiary, who conferred with him, had judged that as much must be paid to Algiers as to the other three powers together; and consequently, that according to this measure, the peace of Algiers would cost from an hundred to an hundred and twenty-five thousand pounds sterling; or from four hundred and sixty to five hundred and seventy-five thousand dollars.

The latter sum seemed to meet the ideas of the Count de Vergennes, who, from a very long residence at Constantinople, was a good judge of what related to the porte, or its dependencies.

A person whose name is not free to be mentioned here, a native of the continent of Europe, who had long lived, and still lives at Algiers, with whom the minister plenipotentiary of the United States, at Paris, had many and long conversations, and found his information full, clear, and consistent, was of opinion the peace of Algiers could not be bought by the United States for less than one million of dollars. And when that is paid, all is not done. On the death of a dey, (and the present one is between seventy and eighty years of age,) respectable presents must be made to the successor, that he may recognize the treaty and very often he takes the liberty of altering it. When a consul is sent or changed, new presents must be made. If these events leave a considerable interval, occasion must be made of renewing presents. And with all this they must see that we are in condition to chastise an infraction of the treaty; consequently some marine force must be exhibited in their harbor from time to time.

The late peace of Spain with Algiers is said to have cost from three to five millions of dollars. Having received the money, they take the vessels of that nation on the most groundless pretexts; counting, that the same force which bound Spain to so hard a treaty, may break it with impunity.

Their treaty with France, which had expired, was about two years ago renewed for fifty years. The sum given at the time of renewal is not known. But presents are to be repeated every ten years, and a tribute of one hundred thousand dollars to be annually paid. Yet perceiving that France, embarrassed at home with her domestic affairs, was less capable of acting abroad, they took six vessels of that nation in the course of the last year, and retain the captives, forty-four in number, in slavery.

It is the opinion of Captain O'Brien, that those nations are best treated who pay a smaller sum in the beginning, and an annual tribute afterwards. In this way he informs us that the Dutch, Danes, Swedes, and Venetians pay to Algiers, from twenty-four to thirty thousand dollars a year, each; the two first in naval stores, the two last chiefly in money. It is supposed, that the peace of the Barbary States costs Great Britain about sixty thousand guineas, or two hundred and eighty thousand dollars a year. But it must be noted that these facts cannot be authentically advanced; as from a principle of self-condemnation, the governments keep them from the public eye as much as possible.

Nor must we omit finally to recollect, that the Algerines, attentive to reserve always a sufficient aliment for their piracies, will never extend their peace beyond certain limits, and consequently, that we may find ourselves in the case of those nations to whom they refuse peace at any price.

The third expedient is to repel force by force. Several statements are hereto annexed of the naval force of Algiers, taken in 1785, 1786, 1787, 1788, and 1789, differing in small degrees, but concurring in the main. From these it results that they have usually had about nine chebecs, from ten to thirty-six guns, and four galleys, which have been reduced by losses to six chebecs and four galleys. They have a forty-gun frigate on the stocks, and expect two cruisers from the grand seignior. The character of their vessels is, that they are sharp built and swift, but so light as not to stand the broadside of a good frigate. Their guns are of different calibres, unskilfully pointed and worked. The vessels illy manœuvred, but crowded with men, one third Turks, the rest Moors, of determined bravery, and resting their sole hopes on boarding. But two of these vessels belong to the government, the rest being private property. If they come out of the harbor together, they separate immediately in quest of prey; and it is said they were never known to act together in any instance. Nor do they come out at all, when they know there are vessels cruising for them. They perform three cruises a year, between the middle of April and November, when they unrig and lay up for the winter. When not confined within the straits, they rove northwardly to the channel, and westwardly to the westward islands.

They are at peace at present, with France, Spain, England, Venice, the United Netherlands, Sweden, and Denmark; and at war with Russia, Austria, Portugal, Naples, Sardinia, Genoa, and Malta.

Should the United States propose to vindicate their commerce by arms, they would, perhaps, think it prudent to possess a force equal to the whole of that which may be opposed to them. What that equal force would be, will belong to another department to say.
