I believe I may venture to write with some certainty on this subject, for I have been on an intimate footing with the person who has transacted for the Court the most part of its money negotiations for more than twelve months past. I knew and cultivated him before he was in favor, and my introduction of him to Mr Jay, procured him the commission on the payment of our bills, and a considerable credit in consequence of the sums supposed to pass through his hands monthly for this purpose. As he has been the founder of the paper system in this country, and as he is likely soon to establish a national bank, he will probably make some figure in the annals of this reign. His name is Francis Cabarrus, born in Bayonne, but sent early to Spain to acquire a knowledge in its commerce, in which his father was considerably interested. His marriage at the age of nineteen (he is now twentynine) displeased his family, from whom after that period he received no assistance. With a small capital, as he himself informed me, he came and established a soap-work in the neighborhood of this city. While there he introduced himself to the notice of the Count de Campomanes, by becoming a member of the patriotic society, the friends of their country; of which the last mentioned gentleman is in a great measure the founder. He soon conciliated his esteem, as well as that of the Governor of the Council of Castile, to whom he became known by means of his friend and patron M. Campomanes. Through their interest he procured a contract to supply wheat and flour, in a time of scarcity, and commenced banker. The last year he proposed his plan for procuring cash for government, on terms mentioned in former letters. His genius is brilliant, active, and enterprising, with more imagination than solidity, although he is by no means deficient in acquired knowledge, arising from reading and reflection, the result of experience. His eloquence, enforced by a very prepossessing countenance and figure, seizes the heart before it convinces the judgment, and this joined to his knowledge of commercial and money transactions, has obtained for him the confidence of M. Musquiz, who consults him at present in all affairs of finance.
