The diplomatist must, however, bear constantly in mind both at work and at play the aims which he is supposed to be serving in the foreign country, and should subordinate his personal pleasure and all his occupations to their pursuit. In this matter the two chief aims which the able negotiator places before himself are, as I have said, to conduct the affairs of his master to a prosperous issue, and to spare no pains to discover the designs of others. And since the means to be employed in both cases are the same, namely by acquiring the esteem, friendship, and confidence of the prince himself and of those in authority around him, there is no surer way of employing them than by becoming personally agreeable. It is marvellous how a _persona grata_ may contrive to uproot even the deepest suspicions and wipe out the memory of the gravest insults. If the diplomatist be looked upon with disfavour at the court he is not a true servant of his master’s interests; for one who is out of favour will not be in a position to know what is going on, and will therefore be but a poor guide to his home government in assisting them to frame their policy. The responsibility for placing the wrong kind of diplomatist in a good position rests of course with the minister who appoints him, but there are many cases in which an ill-fitting appointment has been redeemed by the dauntless assiduity and unfailing courtesy of the diplomatist himself; but since this imposes an unnecessary strain upon the ambassador, the Foreign Minister should ever have a care to appoint suitable men to all foreign posts. [Sidenote: _Support from Home._] I have already described those characteristics which compose suitability; I will but add here that no diplomatist can succeed in his foreign task unless he is well supported by his own government and given every opportunity to understand its policy. By this means he will be in a position to exploit every situation as far as may be to advantage, and he will also be able to deny false rumours set afloat by the enemy. This support from his home government implies a complimentary application on his part, for it is of the highest importance that he should keep himself apprised of all contemporary movements in his own country; that he should know intimately the personal character both of the sovereign and of his Foreign Minister, so that in moments of doubt he may be able to guess shrewdly what is in the mind of those who employ him. Without such knowledge he will certainly go astray, and without a constant contact with his home government the conduct of diplomacy cannot possibly prosper in his hands.
