his master's dressing gown and
slippers, and, placing them to hand, went into the bedroom.

By this time the two watchers had crept from their concealment near
enough to note what he was doing in the bedroom. He was stooping over
the comb which Mr. Gryce had left lying on the floor. This small object
in such a place seemed to surprise him. He took it up, shook his head,
and put it back on the dresser. Then he turned down his master's bed.

"Poor fool!" murmured Miss Butterworth as she and her companion crept
back to their old place behind the parlor curtains, "he has forgotten
everything but his old routine duties. We shall get nothing from this
man."

But she stopped suddenly; they both stopped. Bartow was in the middle of
the study, with his eyes fixed on his master's empty chair in an
inquiring way that spoke volumes. Then he turned, and gazed earnestly at
the rug where he had last seen that master lying outstretched and
breathless; and awakening to a realization of what had happened, fell
into his most violent self and proceeded to go through the series of
actions which they were now bound to consider a reproduction of what he
had previously seen take place there. Then he went softly out, and crept
away upstairs.

Mr. Gryce and Miss Butterworth stepped at once into the light, and
surveyed each other with a look of marked discouragement. Then the
latter, with a sudden gleam of enthusiasm, cried quickly:

"Turn on another color, and let us see what will happen. I have an idea
it will fetch the old man down again."

Mr. Gryce's brows went up.

"Do you think he can see through the floor?"

But he touched a button, and a rich blue took the place of the violet.

Nothing happened.

Miss Butterworth looked disturbed.

"I have confidence in your theories," began Mr. Gryce, "but when they
imply the possibility of this man seeing through blank walls and obeying
signals which can have no signification to any one on the floor
above----"

"Hark!" she cried, holding up one finger with a triumphant air. The old
man's steps could be heard descending.

This time he approached with considerable feebleness, passed slowly into
the study, advanced to the table, and reached out his hands as if to
lift something which he expected to find there. Seeing nothing, he
glanced in astonishment up at the book shelves and then back to the
table, shook his head, and suddenly collapsing, sank in a doze on the
nearest chair.
