"You remember, I suppose, that I was to write you abundance of letters from Hanover; but as one of the most distinguished qualities of a publician is secrecy, you must not expect from me any arcanas of state. There is another thing that is necessary to establish the character of a politician, which is to seem always to be full of affairs of State; to know the consultations of the Cabinet Council when at the same time his politics are collected from newspapers. Which of these two causes my secrecy is owing to I leave you to determine. There is yet one thing more that is extremely necessary for a foreign minister, which he can no more be without than an artisan without his tools; I mean the terms of his art. I call it an art or a science because I think the King of France has established an academy to instruct the young Machiavelians of his country in the deep and profound science of politics. To the end I might be qualified for an employment of this nature, and not only be qualified myself, but (to speak in the style of Sir John Falstaff) be the cause of qualification in others, I have made it my business to read memoirs, treatises, etc. And as a dictionary of law-terms is thought necessary for young beginners, so I thought a dictionary of terms of State would be no less useful for young politicians. The terms of politics being not so numerous as to swell into a volume, especially in times of peace (for in times of war all the terms of fortifications are included), I thought fit to extract them in the same manner for the benefit of young practitioners as a famous author has compiled his learned treatise of the law, called the 'Doctor and Student.' I have not made any great progress in this piece; but, however, I will give you a specimen of it, which will make you in the same manner a judge of the design and nature of this treatise. "_Politician_: What are the necessary tools for a Prince to work with? "_Student_: Ministers of State. "_Politician_: What are the two great qualities of a Minister of State? "_Student_: Secrecy and despatch. "_Politician_: Into how many parts are the Ministers of State divided? "_Student_: Into two. First, Ministers of State at home; secondly, Ministers of State abroad, who are called Foreign Ministers. "_Politician_: Very right. Now as I design you for the latter of these employments I shall waive saying anything about the first of these. What are the different degrees of Foreign Ministers? "_Student_: The different degrees of Foreign Ministers are as follows: First, Plenipotentiaries; second, Ambassadors-Extraordinary; third, Ambassadors in ordinary; fourth, Envoys-Extraordinary; fifth, Envoys-in-ordinary; sixth, Residents; seventh, Consuls; and eighth, Secretaries. "_Politician_: How is a Foreign Minister to be known? "_Student_: By his credentials. "_Politician_: When are a Foreign Minister's credentials to be delivered?
