nd her poll parrot for to-night," a
voice soft and tinkling drawled.

This time Janet laughed. "How about your drawl, Taffy?" she inquired.

"Oh, dear, this will never do," Phyllis protested. "We will all have
to keep as quiet as possible and only answer 'yes' and 'no.'"

Sally's blue eyes opened wide behind her mask of black satin.

"Oh, but that won't be any fun at all!" she cried.

"We might mumble everything we want to say," suggested Janet; "and if
we all do it, it will be more confusing than ever."

"Good idea, 'How do you do this evening; isn't the room beautiful?'"

"Well, then let's go in and pay our respects to Muriel; she and her

"How do you do," they mumbled as they shook hands.

Muriel Grey, dressed, as Miss Pringle had suggested, in the dainty
pinks and blues of a Dresden shepherdess, stood beside her mother. She
was not masked as her guests were, and her puzzled surprise was plain
to be seen.

"Why, who can you be?" she exclaimed. "I have guessed every girl and
boy so far, but I haven't the slightest idea who you are. Please say
something," she begged.

"You look very pretty to-night."

"What a lot of people there are."

"We are all so glad to be here."

"Think hard and you will surely guess."

All four answers were mumbled at once and poor Muriel was more confused

"I think your costumes are delightful and it is great fun to have four
unknown guests," Mrs. Grey said. "I shall be
