and as much mystified as even the youngest
present.

"Why, who was it? and where did she go to?" asked one of the little
girls.

"She was not to be found; nor was the dog," replied Percy. "They seem
to have got away very quickly."

"Well, I wish I knew who she was, and whether the dog is after her
yet," said Don, his younger brother. "I think I'll go out to the
street and see if they are anywhere in sight."

"'Tisn't worth while, little chap; you'll not find 'em," said a voice
from the hall which sounded very much like the one that had spoken
first.

"Is it your doing? did you bring that dog here?" asked the lad,
jumping up and going toward the door.

"Yes," said the voice; "but you needn't worry; she wasn't hurt, though
she did do sich tall screamin'. That was jist fer fun and to scare you
folks."

"Who are you, anyhow?" asked Don; "and why don't you show yourself?
You neither act nor talk like a gentleman."

"Don't I?" asked the voice, ending with a coarse laugh.

"I wouldn't go out there if I were you, little boy; that fellow might

"Oh, how did it get in there?" he clapped his hand upon his pocket.
"Why--why, it isn't there! Where is it?" he cried, turning round and
round, looking down at his feet, then farther away under chairs and
tables. "I can't find it," he said presently, looking much bewildered.
"Grandpa, I never saw such things happen in your house before--no,
nor anywhere else. What's the matter with me? am I going blind?"

"No, my boy," said the doctor, "we all seem to be as blind as
yourself--hearing people talk but not able to see them."

"None so blind as those that won't see," remarked the voice that had
spoken last, but this time coming apparently from the doorway. "Here I
am, and you are welcome to look at me as closely as you please."

A sudden fierce bark from their very midst seemed to answer her. It
was so sudden and sharp that everyone started, and some of the
children screamed.

"Nero, be
