For what seemed at least half-an-hour, but was probably not more than ten minutes, the voracious fish tacked this way and that, approaching me a little nearer every tack, until at length they were so close that I could have leapt upon the back of the nearer one, so close that I could distinctly see their entire bulk; and the sight turned my blood cold, for they were veritable monsters, one of them being fully twenty feet long from snout to the tip of the unevenly fluked tail, while the other was perhaps three feet shorter.
