The caveat about Walton's boasting of his courage in the opening letter
(Letter 1.4), and at the beginning of
the second (Letter 2.1) his insisting
on the same attribute in his crew, must extend here as well. Although
certainly it is hard to see in this tribute to his lieutenant any trace
of diabolic lineaments, still, the combination of terms driving him are
inherently those of Milton's Satan.
