I wrote you March the 15th, with postscripts of the 18th and 19th. Since that, yours of January the 3rd, No. 10, January the 15th, No. 11, from Madrid, February the 6th, No. 12, and February the 12th, No. 13, from Lisbon, have been received. They covered a letter from Mr. Carmichael, the only one we have from him of later date than May, 1789. You know that my letter to him, of which you were the bearer, took notice of the intermission of his correspondence, and the one enclosed to him in my letter to you of March the 15th, being written when this intermission was felt still stronger, as having continued so much longer, conveyed stronger marks of dissatisfaction. Though his letter, now received, convinces us he has been active in procuring intelligence, yet it does not appear that he has been equally assiduous in procuring means of conveyance, which was the more incumbent on him, in proportion as the government was more jealous and watchful. Still, however, I wish him to receive the letter now enclosed for him, herein, as it softens what had been harder said, and shows a disposition rather to look forward than backward. I hope you will receive it in time to forward with the other. It contains important matter, pressing on him, as I wish to do on you and have done on Mr. Short, to engage your respective courts in a co-operation in our navigation act. Procure us all the information possible, as to the strength, riches, resources, lights, and dispositions of Brazil. The jealousy of the court of Lisbon on this subject, will, of course, inspire you with due caution in making and communicating these inquiries. The acts of the three sessions of Congress, and Fenno’s papers from April, 1790, were sent you with my last. You will now receive the continuation of Fenno’s paper. I send for Mr. Carmichael, also, laws and newspapers, in hopes you may find some means of conveying them to him. I must sometimes avail myself of your channel to write to him, till we shall have a Consul at Cadiz. I have the honor to be, with great and sincere esteem, Dear Sir, your most obedient, humble servant, Th: Jefferson. LETTER LIX.--TO WILLIAM CARMICHAEL, April 11,1791 TO WILLIAM CARMICHAEL.
