For some days their fancy dresses were an all engrossing source of thought and topic with the girls and their chaperone; but, after many changes of mind, costumes of the reign of Mary Stuart were selected by them, Mary choosing blue, slashed and trimmed with white, as suited to her blonde complexion, and Ellinor rose colour, trimmed and slashed with black, as suited to her dark hair and hazel eyes, and wonderfully handsome and piquante they looked.

On the forenoon of the ball the baron arrived with three magnificent bouquets and two beautiful fans for the sisters—the best that could be obtained in the Neuer Wall.

'How charming—how kind!' exclaimed both, blushing with pleasure.

'For our dance to-night,' said Rolandsburg, in his most insinuating tone, to Mary, 'how many waltzes are you to give me?' he asked, in a lower voice.

'How many do you want?' asked Mary, coquettishly.

'I would like them all of course—save those I may have with Miss Ellinor; but that is too much to expect.'

As all this implied more than words, Mary appeared not to hear, and addressed Mrs. Deroubigne.

In due time they were attired, and drove through the brilliantly lighted streets to the Stadt Theatre in the Dammthor Strasse, where the Burgher Guard, in quaint uniforms, were under arms to receive the burgomasters and four Syndics of the city, who wear on state occasions high-crowned hats and black velvet cloaks, with ruffs and swords; and there, about the entrances, were a crowd of blooming Vierlander flower-girls, selling bouquets and button-holes, their quaint hats or gold-embroidered caps, their bodices of crimson or black, covered with gold-broidery, and their short blue skirts, making each a picture.

'I shall dance with no one else but you to-night,' said the uhlan, in his softest tone, to Mary.

'No one else?' said she.
