lace and jump upon his
master's knees. Dr. Silence, patient and determined, settled down once
more to his book. The animals soon slept; the fire blazed cheerfully;
and the cold fog from outside poured into the room through every
available chink and crannie.

For a long time silence and peace reigned in the room and Dr. Silence
availed himself of the quietness to make careful notes of what had
happened. He entered for future use in other cases an exhaustive
analysis of what he had observed, especially with regard to the effect
upon the two animals. It is impossible here, nor would it be
intelligible to the reader unversed in the knowledge of the region known
to a scientifically trained psychic like Dr. Silence, to detail these
observations. But to him it was clear, up to a certain point--and for
the rest he must still wait and watch. So far, at least, he realized
that while he slept in the chair--that is, while his will was
dormant--the room had suffered intrusion from what he recognized as an
intensely active Force, and might later be forced to acknowledge as
something more than merely a blind force, namely, a distinct
personality.

So far it had affected himself scarcely at all, but had acted directly
upon the simpler organisms of the animals. It stimulated keenly the
centres of the cat's psychic being, inducing a state of instant
happiness (intensifying its consciousness probably in the same way a
drug or stimulant intensifies that of a human being); whereas it alarmed
the less sensitive dog, causing it to feel a vague apprehension and
distress.

His own sudden action and exhibition of energy had served to disperse it
temporarily, yet he felt convinced--the indications were not lacking
even while he sat there making notes--that it still remained near to
him, conditionally if not spatially, and was, as it were, gathering
force for a second attack.

And, further, he intuitively understood that the relations between the
two animals had undergone a subtle change: that the cat had become
immeasurably superior, confident, sure of itself in its own peculiar
region, whereas Flame had been weakened by an attack he could not
comprehend and knew not how to reply to. Though not yet afraid, he was
defiant--ready to act against a fear that he felt to be approaching. He
was no longer fatherly and protective towards the cat. Smoke held the
key to the situation; and both he and the cat knew it.

Thus, as the minutes passed, Joh
