After supper, all the company put on masks with which they had provided themselves. The Landgravine was led to the ballroom by her partner, an owlish colonel, and the other couples followed. Her highness stopped at the upper end of the room, the second couple stopped immediately below this, and at last there was a double file extending the length of the hall. This arrangement seemed to promise a country-dance, but when the music began, Dick found that a form of minuet was intended. When this had been walked through, everybody sat down, except the Landgravine, who then danced with several different gentlemen in succession. After this there were minuets and country-dances. The company was augmented by maskers from the town, some in fancy dresses; while several who belonged to the court, having meanwhile slipped out, returned in different costume, so as to be really disguised,--for on first entering the masquerade-room, all were known, notwithstanding their masks. Everybody was now on a footing, and the maskers mingled promiscuously. But Dick remained with Catherine, who showed no desire for other company. He thought himself in the midst of paradise, until suddenly she said: "Her highness is retiring. I must go." "But, mademoiselle, the others are not going!" "The others are not keepers of her highness's robes," said Catherine. "But one moment! When may I see you again?" "How can I say? My hours of duty are long. I am usually free in the afternoon, from three to five o'clock. On occasions like this, sometimes I attend her highness, sometimes I may do as I please." "From three to five, you say. I suppose you remain in the palace then?" "Except when I visit my brother. I must go now, monsieur. _Au revoir!_" In a moment she was lost in the crowd. You may be sure much had been said, between their opening colloquy at supper and their brief dialogue at parting, to bring about the tacit understanding of a future meeting. So she was in the habit of going to see her brother! Dick had learned that the Prussian system was followed in Cassel,--that the troops, instead of being lodged in barracks, were quartered with citizens. He walked the next morning to the drill-ground and armory of the foot-guards, and, happily meeting Captain von Romberg, learned where Gerard had lodgings. He went immediately to the house, which was in a street running east from the platz and through the southern extremity of the old town. It was the house of a glover, whose shop was on the ground floor. Gerard was out on duty.
