Balook, too, languished. He was five hundred kilograms of helplessness, bawling plaintively in his pen. After a
few days he gave up and lay there whimpering, lacking the initiative even to feed. The joy of companionship he
had learned was now cruelly denied, and he had no way to understand. The lie-detector needle remained
steadily on FALSE, confirming that Balook was really in trouble.
Don Scale was not a stupid man, or an unduly arrogant one. He recognized the situation and resolved to make
the lesser evil of it. Young Thor Nemmen received a formal pass and was added to the payroll at a nominal rate,
with the title "Companion."
That had been six years ago. Ever since, Thor had visited Balook daily, playing with him, climbing all over him,
sharing his food in a fashion, snoozing with him. The animal had grown enormously, even after allowing for his
nature; Scale's charts showed above-projected gains. Thor taught the rhino how to heed his directions when he
rode, so they could share more fun by exploring the compound. Balook was never allowed to run loose within
the "business" section of the Project, but when he was with Thor it didn't count. Balook was no genius, even for
a rhino, but he was quick enough to learn that he had greater freedom when playing Thor's game than he did
otherwise. Besides, exploring was fun. There were green growing trees out there, his favorite food after he was
weaned from milk.
During school season they had to make special arrangements, for Balook could not understand the reason for
Thor's absences. Thus Thor was permitted to attend TV classes—with the set in Balook's pen. This was an
unforeseen blessing, for though Thor was willing to learn anything, he hated being crammed into a classroom
with his peers. Boys his age tended to be loutish. They respected only those who had the muscle or skill to
knock heads, and Thor was of barely average physical stature and had indifferent coordination. Some few boys
had the compensation of intellect; Thor was not competitive there either. As a person he was rated at sixes and
sevens; nobody found him worthwhile. Balook had freed him of that. To Balook, he was the greatest person in
the world.
The animal seemed to enjoy the programs, too,
though he could hardly have understood them.
Probably it was merely the rhino's feeling of
participation with his friend that gave him pleasure.
Once Thor had dreamed that he had dropped in on
Balook unexpectedly, and caught him doing
differential equations with his hoof in the dirt while
the TV had a college math class on. 'I didn't know
you could do that!' he exclaimed. 'Well, you never
asked,' Balook replied. Then Thor had caught on,
and woke up laughing. It was a foolish dream;
Balook was the most remarkable creature on earth
as he stood; he didn't need to be a genius too.
Once Balook had fallen ill, despite the precautions
of expensive veterinarians. Thor had to make special
arrangements to stay with him day and night; the
animal had little incentive to live without his friend.
While Thor would never have wished any misery on
Balook, it still gratified him to be so strongly needed.
Then there was the time Thor himself had surgery
for a small pollution-tumor on the lung. Air standards were strict, but violations occurred, and there was
