7. (a) The spectacle these men presented would under other circumstances have been
so absurd as to make one laugh, but here it was tragic. Sitting in a tight little
circle with their knees drawn up and their heads together, with the goats
trying to crawl under them, they had that look of intense expectation on their
screwed-up features that one sees on the faces of spectators waiting to hear a
big gun go off. From the time we had first heard the tigress from the ridge,
neither the men nor the goats had made a sound, beyond on suppressed cough.
They were probably by now frozen with fear which they had every right to be
and even if were, I take my hat off to those four men, who had the courage to
do what I, had I been in their position, would not have dreamt of doing. For
seven days they had been hearing the most exaggerated and terrifying tales
of this dreadful beast that had dept them awake the past two nights, an now,
while darkness was coming on, and sitting unarmed in a position where they
could see nothing, they were listening to the man-eater coming nearer and
nearer; grater courage, and greater faith, it is not possible to conceive.
