"Yes, sir; my credentials are included with matters more important." "You know the contents of the enclosure?" "Only the general import. The sender of these missives has divulged much to me. You may trust me." "I trust you implicitly, Mr. Swartwout. The embassy on which you come is of a delicate character, requiring discretion--as secret service always does." The general opened the package, and found that it contained three separate papers. The first was a letter introducing Samuel Swartwout, and vouching for his prudence, courage and trustworthiness. The other two papers were in hieroglyphics. Wilkinson, smiling graciously, turned to the messenger. "Perhaps I had best be alone while I examine the other documents. I will see that you are made comfortable." An officer was summoned. "Captain Danvers, this gentleman is my guest. Please see that he is suitably quartered and provided with a seat at my table. He is the son of an old military acquaintance of mine." The cipher agreed upon by Wilkinson and Burr was a composite of arbitrary signs and of numerals representing letters of the alphabet. The first riddle read by Wilkinson was a private letter to Burr from General Dayton. Part of the contents ran thus: "Under the auspices of Burr and Wilkinson, I shall be happy to engage, and when the time arrives, you will find me near you. Write and inform me, by first mail, what may be expected from you and your associates.... Wealth and honor, courage and union, Burr and Wilkinson! Adieu." The other communication was from Burr himself.
