Franklin, receiving these epistles, was greatly vexed at the jeopardy into which the rash zeal of Adams had suddenly plunged the American interests in France. His indignation was not likely to be made less by the fact that all this letter-writing to de Vergennes was a tacit reproach upon his own performance of his duties and a gratuitous intrenchment upon his province. The question which presented itself to him was not whether the argument of Adams was right or wrong, nor whether the distinction which de Vergennes sought to establish between American citizens and foreigners was practicable or not. This was fortunate, because, while Adams in the States had been forced to ponder carefully all the problems of a depreciating paper currency, Franklin in France had neither necessity, nor opportunity, nor leisure for studying either the ethics or the solution of so perplexing a problem. He now hastily made such inquiries as he could among the Americans lately arrived in Paris, but did not pretend "perfectly to understand" the subject. To master its difficulties, however, did not seem essential, because he recognized that the obvious duty of the moment was to say something which might at least mitigate the present wrath of the French ministry, and so gain time for explanation and adjustment in a better state of feeling. He had once laid down to Arthur Lee the principle: "While we are asking aid it is necessary to gratify the desires and in some sort comply with the humors of those we apply to. Our business now is to carry our point." Acting upon this rule of conciliation, he wrote, on July 10, to de Vergennes:-- "In this I am clear, that if the operation directed by Congress in their resolution of March the 18th occasions, from the necessity of the case, some inequality of justice, that inconvenience ought to fall wholly upon the inhabitants of the States, who reap with it the advantages obtained by the measure; and that the greatest care should be taken that foreign merchants, particularly the French, who are our creditors, do not suffer by it. This I am so confident the Congress will do that I do not think any representations of mine necessary to persuade them to it. I shall not fail, however, to lay the whole before them."
