I deem it proper, however distasteful the subject may be, both to you and myself, to relate to you a conversation which I had on Tuesday last with Major-General Sir Edward Cust, the master of ceremonies at this court, concerning my court costume. I met him at the Traveller’s Club, and after an introduction, your circular on this subject became the topic of conversation. He expressed much opposition to my appearance at court “in the simple dress of an American citizen.” I said that such was the wish of my own Government and I intended to conform to it, unless the queen herself would intimate her desire that I should appear in costume. In that event, I should feel inclined to comply with her majesty’s wishes. He said that her majesty would not object to receive me at court in any dress I chose to put on; but whilst he had no authority to speak for her, he yet did not doubt it would be disagreeable to her if I did not conform to the established usage. He said I could not of course expect to be invited to court balls or court dinners where all appeared in costumes; that her majesty never invited the bishops to balls, not deeming it compatible with their character; but she invited them to concerts, and on these occasions, as a court dress was not required, I would also be invited. He grew warm by talking, and said that, whilst the queen herself would make no objections to my appearance at court in any dress I thought proper, yet the people of England would consider it _presumption_. I became somewhat indignant in my turn, and said that whilst I entertained the highest respect for her majesty, and desired to treat her with the deference which was eminently her due, yet it would not make the slightest difference to me, individually, whether I ever appeared at court. He stated that in this country an invitation from the queen was considered a command. I paid no attention to this remark, but observed that the rules of etiquette at the British court were more strict even than in Russia. Senator Douglas of the United States had just returned from St. Petersburg. When invited to visit the czar in costume, he informed Count Nesselrode that he could not thus appear. The count asked him in what dress he appeared before the President of the United States. Mr. Douglas answered in the dress he then wore. The count, after consulting the emperor, said that was sufficient, and in this plain dress he visited the emperor at the palace and on parade, and had most agreeable conversations with him on both occasions. Sir Edward then expressed his gratification at having thus met me accidentally,—said he had just come to town for that day and should leave the next morning, but would soon do himself the honor of calling upon me.
