The moment was nervous--as far as the private secretary knew, quite the most critical moment in the records of American diplomacy--but the story belongs to history, not to education, and can be read there by any one who cares to read it. As a part of Henry Adams's education it had a value distinct from history. That his father succeeded in muzzling Palmerston without a public scandal, was well enough for the Minister, but was not enough for a private secretary who liked going to Cambridge House, and was puzzled to reconcile contradictions. That Palmerston had wanted a quarrel was obvious; why, then, did he submit so tamely to being made the victim of the quarrel? The correspondence that followed his note was conducted feebly on his side, and he allowed the United States Minister to close it by a refusal to receive further communications from him except through Lord Russell. The step was excessively strong, for it broke off private relations as well as public, and cost even the private secretary his invitations to Cambridge House. Lady Palmerston tried her best, but the two ladies found no resource except tears. They had to do with American Minister perplexed in the extreme. Not that Mr. Adams lost his temper, for he never felt such a weight of responsibility, and was never more cool; but he could conceive no other way of protecting his Government, not to speak of himself, than to force Lord Russell to interpose. He believed that Palmerston's submission and silence were due to Russell. Perhaps he was right; at the time, his son had no doubt of it, though afterwards he felt less sure. Palmerston wanted a quarrel; the motive seemed evident; yet when the quarrel was made, he backed out of it; for some reason it seemed that he did not want it--at least, not then. He never showed resentment against Mr. Adams at the time or afterwards. He never began another quarrel. Incredible as it seemed, he behaved like a well-bred gentleman who felt himself in the wrong. Possibly this change may have been due to Lord Russell's remonstrances, but the private secretary would have felt his education in politics more complete had he ever finally made up his mind whether Palmerston was more angry with General Butler, or more annoyed at himself, for committing what was in both cases an unpardonable betise.
