Miranda, continued the memorialists, remained fourteen days in Washington after this conversation, and returned to New York confident of the silent approval of Government. Eleven days before the Leander sailed, he sent a letter to Mr. Madison, inclosing another to Mr. Jefferson, both of which he read to Ogden and to Smith. He assured Mr. Madison that he had conformed in every way to the intentions of Government, and requested him to keep the secret. To Mr. Jefferson he wrote in a strain more fashionable ten years before than then, but well adapted to the sentimentality, both scientific and political, of the "Philosophic President." Here it is:-- "I have the honor to send you, inclosed, the 'Natural and Civil History of Chili,' of which we conversed at Washington,--and in which you will, perhaps, find more than in those which have been before published on the same subject, concerning this beautiful country. "If ever the happy prediction, which you have pronounced on the future destiny of our dear Columbia, is to be accomplished in our day, may Providence grant that it may be under your auspices, and by the generous efforts of her own children! We shall then, in some sort, behold the revival of that age, the return of which the Roman bard invoked in favor of the human race:-- "'The last great age foretold by sacred rhymes Renews its finished course; Saturnian times Roll round again; and mighty years, begun From this first orb, in radiant circles run.'" On Miranda's reports, these letters, and the fact that the Leander had not been seized, they rested their case, and prayed for the interference of Congress in their behalf. Congress unanimously granted the petitioners leave to withdraw. Such evidence as this, not only hearsay, but heard from the party most interested in misrepresenting the Administration, was not entitled to much consideration. It had, moreover, the additional disadvantage of proving nothing against the President and Secretary, even if every word of it were admitted as true. Public attention was diverted from the Leander, Captain Lewis, to the Leander, Captain Whitby. This English frigate was cruising off Sandy Hook, bringing to inward and outward bound vessels, searching them for articles contraband of war, and helping herself to able-bodied seamen who looked like British subjects. All of which was meekly submitted to in 1806. Mr. Jefferson could not overcome his doubts as to the constitutionality of a fleet, and the Opposition had the twofold pleasure of chuckling over the insults offered by John Bull to a government with French proclivities, and of reproaching the party in power with its supineness and want of spirit.
