Within the last six weeks I have had the good fortune to make the acquaintance of several noble families of the very highest rank, and I am beginning to receive many attentions from that class. Their coldness and jealousy towards strangers generally are fast disappearing in relation to myself. Some accidental circumstances which it would be useless to detail have contributed much to this result. I consider this a fortunate circumstance, as the nobility exercise great influence in this country. I think in my despatch of the 9th of August last I spoke rather too harshly of them as a class; and although, with a few exceptions, I by no means admire them, yet this shows how dangerous it is to form opinions too hastily. The influence of the example of the present emperor and empress, in the correctness of their private deportment, is doing their nobility much good. Too much care cannot be taken in selecting a minister for this court. Indeed it would be difficult to find many suitable persons in our country for this mission. In London and in Paris, our ministers enjoy the consideration to which they are entitled from the exalted character of their country; but here the character of the country must depend in a considerable degree upon that of the minister. The principles of the American Government, the connection between our greatness and prosperity as a nation, and the freedom of our institutions, are a sealed book in regard to the Russians. Their own press dare publish nothing upon the subject, and all foreign papers, unless those of the most illiberal character, are prohibited. The higher classes here must in a great degree receive their information concerning our country from our minister. This sufficiently points out what ought to be his qualifications, and I regret my own deficiency in some important particulars. Great talents are by no means so requisite as an easy address, insinuating manners, and a perfect knowledge of the French language. (In the latter I have already made considerable advances.) Above all he ought to have a genuine American heart, in which I know I am not deficient, always anxious to seize every favorable opportunity, and many such occur, of making an impression in favor of his country. There is one great disadvantage, however, under which a minister here labors; and that is, the total inadequacy of the salary. These people are fond of extravagance and show, and have not the least taste for Republican simplicity and economy. In order that a minister may hold a high place in their esteem, he must be able to return their civilities. They judge much by appearances. The want of this reciprocity will be attributed to the meanness of the minister or that of his country, or both. Even the representative of his Sardinian Majesty receives $16,000 per annum. Now if I had $100,000 per annum, I would not pursue any course of conduct in this respect which I should be ashamed to exhibit
