answered Don; "we've never seen him at all--no,
not one of us; and if we had, we wouldn't have done him a bit of
harm."

Just as Don pronounced the last word, a shrill little bark sounded out
from behind Cousin Ronald's chair.

"Why, there he is now!" exclaimed Don, hurrying to the spot. "Why, no,
he isn't! How does he get away so fast?"

"He seems to be an invisible dog, Don," said his brother Percy; "and,
if I were you, I wouldn't let him trouble me any more."

"No; but I've set out to find him, and I don't mean to give it up,"
replied the little fellow.

"That's right, Don," laughed his father. "I'm pleased to see that you
are not easily discouraged."

"But he might as well be, for there's no dog thar," said the voice
from the hall. "He's a plucky little feller, but he'll not find that
thar dog if he looks all night."

"I guess I'll find you then," said Don, running to the door and
looking searchingly about the hall. "Well, it's the queerest thing!"
he exclaimed. "There's nobody here--nobody at all!"

"Is the boy blind, that he goes right past a body and never sees him?"
asked the voice; and Don turned quickly to see the speaker, who seemed
close behind him. But no one was there, and Don looked really
frightened. Cousin Ronald noticed it, and said in kindly tones, "Don't
be scared, sonny, it was I who spoke; and I wouldn't harm you for all
I am worth."

"You, sir?" said Don, looking utterly astonished. "How could it be
you? for the fellow was over here, and you are over there."

"No; I only made it sound so," Mr. Lilburn said with an amused laugh;
"and I must confess that I have been doing all this screaming,
scolding, and barking just to make a bit of fun for you all."

At that the children crowded around the old gentleman, eagerly asking
how he did it and what else he could do.

"I can hardly tell you how," he said, "but perhaps I can show some
other specimens of my work." He was silent for a moment, seemingly
thinking. Then a loud, rough voice said: "Hello there, youngsters,
what are you bothering with that stupid old fellow for? Why don't you
leave him and go off to your sports? It would be a great deal more
fun."

The children turned toward the place from which the voice seemed to
come, but saw no one. They were surprised at first, laughed, asking,
"Was that you, Uncle Ronald?"

"Nobody else," he said with a smile.

"Oh, hark! there's music!" cried one of the little girls; and all
listened
