Among the celebrities in the gallery I noticed the widow of Daniel Webster. But as I have given my opinion about the beauty of women, I shall make no departure from it, unless the ends shall justify the means. The wife of the Lieutenant General, Julia Dent Grant, occupied a front seat in the gallery, just as she had a right to do. She wore a pink hat, a red plaided scarf, and black gloves, and a little upstart woman who sat near me had the impudence to say the general’s lady “looked horrid.” She no doubt would have been put out for the above expression but the gallery was so crowded that no officer could be found at the proper time to discharge his duty. Just before the time arrived for opening this great historical meeting Washington contained two sets of people besides the saints and sinners, and these were the envious and the envied. The envied were the fortunate holders of tickets to the meeting, and the envious were the great outsiders. But when the third hour of that memorable speaking arrived the tables were turned. Members began to twist around as if they were schoolboys, the victims of pins which in some unaccountable way had been put in the cushions of their chairs, points upward. A celebrated New York politician treated himself to a newspaper; tobacco-boxes circulated freely and all sorts of expressions came over the human countenance which are possible when men get into positions where they are obliged to behave themselves and don’t want to. I will add, everything must come to an end, and so did this great occasion. As I have nearly filled the allotted space, I must only glance at the great ball at the Marquis De Montholon’s and say it was equal, but not superior, to the same kind of parties given by our accomplished countrywoman, Mrs. Senator Sprague. In both cases no expense is spared in the entertainment of guests, and any amount of greenbacks, duty in the shape of costly silks and laces; but I learn that precious stones are more or less abandoned, since the shoddy and petroleum have learned to shine. The shadows of Lent are upon us, and this fact crowded the President’s last levee to suffocation. It was exceedingly painful to notice the violation of good taste in some of my countrywomen by their appearance before the Executive and the ladies of the mansion in bonnet and wrappings. Unless ladies can conform to the usages of good society they had better remain at home. OLIVIA. ADVICE POLITICAL. PRESIDENT JOHNSON GIVES EVIDENCE OF HIS OCCUPANCY OF THE CHAIR OF THE EXECUTIVE.
