Light refreshments were brought in on little trays, and the girls were invited to partake.  The three young hostesses acted with _aplomb_ and much tact.  Dull girls were drawn out of themselves, lively girls were placed with suitable companions.  Games were proposed, which were all conducted in a spirited and lively manner, and finally the proceedings ended with a gay dance.  It was at this moment, just when the dance was in full swing, that Sir John Wallis came up and offered his arm to Florence.
