By ten o'clock there were many in the great room which had been made ready for the dancing, and rather a brave company it might have been called. We had at least the splendor of the foreign diplomats' uniforms for our background, and to this we added the bravest of our attire, each one in his own individual fashion, I fear. Thus my friend Jack Dandridge was wholly resplendent in a new waistcoat of his own devising, and an evening coat which almost swept the floor as he executed the evolutions of his western style of dancing. Other gentlemen were, perhaps, more grave and staid. We had with us at least one man, old in government service, who dared the silk stockings and knee breeches of an earlier generation. Yet another wore the white powdered queue, which might have been more suited for his grandfather. The younger men of the day wore their hair long, in fashion quite different, yet this did not detract from the distinction of some of the faces which one might have seen among them--some of them to sleep all too soon upturned to the moon in another and yet more bitter war, aftermath of this with Mexico. The tall stock was still in evidence at that time, and the ruffled shirts gave something of a formal and old-fashioned touch to the assembly. Such as they were, in their somewhat varied but not uninteresting attire, the best of Washington were present. Invitation was wholly by card. Some said that Mrs. Polk wrote these invitations in her own hand, though this we may be permitted to doubt.
