If it were not that the persons with whom your lordship has to correspond, can some of them barely spell their native tongue, I would recommend to your lordship the use of cyphers. But no, you might as well write the language of Mantcheux Tartars. For consider, your letters may be intercepted. It is true, they have not many perils to undergo. They are not handed from post-house to post-house. There are no impertinent office-keepers to inspect them by land. There are no privateers to capture them by sea. But, my lord, they have perils to encounter, the very recollection of which makes me tremble to the inmost fibre of my frame. They are ale-houses, my lord. Think for a moment of the clattering of porter-pots, and the scream of my goodly hostess. Imagine that the blazing fire smiles through the impenetrable window, and that the kitchen shakes with the peals of laughter. These are temptations, my lord, that no mortal porter can withstand. When the unvaried countenance of his gracious sovereign smiles invitation upon him from the weather beaten sign-post, what loyal heart but must be melted into compliance. From all these considerations, my lord, I would advise you to write with invisible ink. Milk I believe will serve the purpose, though I am afraid, that the milk that is hawked about the streets of London, has rather too much water in it. The juice of lemon is a sovereign recipe. There are a variety of other preparations that will answer the purpose. But these may be learned from the most vulgar and accessible sources of information. And you will please to observe, that I suffer nothing to creep into this political testament, more valuable than those of Richelieu, Mazarine, and Alberoni, that is not entirely original matter. My lord, I defy you to learn a single particular of the refinements here communicated from the greatest statesman that lives. They talk of Fox! He would give his right hand for an atom of them!
