He must pay the prince assiduous attention, and thus acquire a sufficient familiarity with him to be able to see and speak to him frequently without ceremony, so that he may be always in a position to know what is going on, and to insinuate into the prince’s mind what is favourable to his master’s design. If he lives in a democratic state he must attend the Diet and other popular assemblies. He must keep open house and a well-garnished table to attract the deputies, and thus both by his honesty and by his presence gain the ear of the ablest and most authoritative politicians, who may be able to defeat a hostile design or support a favourable one. If people of this kind have a freedom of _entrée_ to the ambassador, a good table will greatly assist in the discovery of all that is going on, and the expense laid out upon it is not merely honourable but extraordinarily useful if only the negotiator himself knows how to profit from it. [Sidenote: _The Value of Good Cheer._] Indeed it is in the nature of things that good cheer is a great conciliator, that it fosters familiarity, and promotes a freedom of exchange between the guests, while the warmth of wine will often lead to the discovery of important secrets. There are several other functions for the employment of public ministers, as for instance that of informing a prince of good or evil tidings regarding his own master, or that of conveying compliments or condolences in a similar case to the prince himself. A negotiator who knows his business will not neglect even the least of such opportunities, and he will perform his function in such a manner as to show that his master is truly interested in all that passes at the foreign court. Indeed the best negotiator is he who forestalls even the orders of his own master, and shows himself so apt a negotiator of his intentions that he is able to act in advance of each event of the kind, and thus present his master’s sentiments in appropriate language before any other foreign diplomatist has even begun to consider the matter. And when he actually receives his master’s orders on the subject, should they turn out to be of a somewhat different character than the expressions he has already used, his own adroitness will enable him to bridge the apparent difference. The diplomatist’s functions cease automatically on the death of his master or on the death of the prince to whom he is accredited, and are not revived until new letters of credence are received. They also come to an end on his withdrawal or upon a declaration of war, but it should be noted that the privileges attached to the office of ambassador under the law of nations continue unbroken, notwithstanding any declaration of war or other interpretation of his functions, and these privileges remain in force until he reaches his own national territory.
