in his previous though unsuccessful attempts
with humans, found after many more anxious minutes he could follow the
thought-and-memory tracks back and back until the dog's whole mind was
open to him.

The puppy had far more of a mentality than Hanlon had ever guessed dogs
had--and he knew they were far from stupid. This one's mind, he could
now see, was immature but latently capable.

Say, this was great! Hanlon probed some more, and found many sketchy
facts--sketchy because the thoughts were incomplete to the puppy, beyond
its experience, and not because the man couldn't read perfectly what was
there. The dog apparently knew a woman--Hanlon got the impression of
skirts--and answered when that goddess called the word "Gypsy."

"Gypsy, eh?" Hanlon said aloud, and immediately the dog wriggled from
beneath his restraining hand, and again tried to climb up and lick
Hanlon's face in a frenzy of adoration.

"Lie down, sir, and be quiet!" Hanlon said sternly, and the puppy did so
instantly, without question or hesitation.

Hanlon thrilled, realizing at once that it was not what he had said that
did the trick--but the fact that he was still inside the dog's mind, and
that it had obeyed his will rather than his words.

"Hey, this needs looking into!"

Without saying the words aloud this time, Hanlon commanded the dog--or
rather, he impressed the command directly onto the puppy's mind with his
own--to get down off his lap onto the deck.

Instantly it leaped down.

"Lie down." The dog did so.

"Roll over." Again silently. But now the puppy merely looked up at him,
imploringly, quivering in an apparent emotion of indecision. Hanlon
realized the puppy didn't know how to "roll over."

"Guess I need to learn how to do it before I can teach, or rather,
command, him to do it," Hanlon grinned wryly to himself. For he realized
that to do so he would have to learn how to control each of the dog's
muscles, and that before he could do that he would have to know what
part of the brain controlled the nerves that made those muscles obey his
commands.

And that, if possible at all, would take one galaxy of a lot of study
and practice.

For the next several minutes, then, he concentrated in making the puppy
do a number of simple tricks, all the time watching carefully to see, if
possible, the connecting links between brain, nerves and muscles.

He was beginning to make a little headway in understanding this triple
co-relation,
