have in object to divide the country between themselves. This is only to substitute one set of barbarians for another, breaking, at the same time, the balance among the European powers. You have been told, with truth, that the Emperor of Morocco has shewn a disposition to enter into treaty with us : but not truly, that Congress has not attended to his advances, and thereby disgusted him. It is long since they took measures to meet his advances. But some unlucky incidents have delayed their effect. His dis positions continue good. As a proof of this, he has lately released freely, and clothed well, the crew of an American brig he took last winter ; the only vessel ever taken from us by any of the States of Barbary. But what is the English of these good dispo sitions ? Plainly this ; he is ready to receive us into the number of his tributaries. What will be the amount of tribute, remains yet to be known, but it probably will not be as small as you may have conjectured. It will surely be more than a free people ought to pay to a power owning only four or five frigates, under twenty-two guns : he has not a port into which a larger vessel can enter. The Algerines possess fifteen or twenty frigates, from that size up to fifty guns. Disinclination on their part, has lately broken off* a treaty between Spain and them, whereon they were to have received a million of dollars, besides great presents in naval stores. What sum they intend we shall pay, I cannot say. Then follow Tunis and Tripoli. You will probably find the tribute to all these powers make such a proportion of the federal taxes, as that every man will feel them sensibly, when he pays those taxes. The question is, whether their peace or war will be cheapest ? But it is a question which should be addressed to our honor, as well as our avarice. Nor does it respect us as to these pirates only, but as to the nations of Europe. If we wish our commerce to be free and uninsulted, we must let these nations see, that we have an energy which at present they disbelieve. The low opinion they entertain of our powers, cannot fail to involve us soon, in a naval war.

I shall send you with this, if I can, and if not, then by the first good conveyance, the Connoissance de terns for the years 1 786 and 1787, being all as yet published. You will find in these the ta bles for the planet Herschel, as far as the observations hitherto made, admit them to be calculated. You will see, also, that Her schel was only the first astronomer who discovered it to be a planet, and not the first who saw it. Mayer saw it in the year 1756, and placed it in the catalogue of his zodiacal stars, supposing it to be such. A Prussian astronomer, in the year 1781, observed that the 964th star of Mayer s catalogue was missing : and the calcula-
