What does the old fellow in the inn at Wallingford tell George and Harris about the trout in the glass - case ?

There are different versions about who caught the fish. An old genial man tells them that:

I caught him just below the lock—leastways, what was the lock then—one Friday afternoon; and the remarkable thing about it is that I caught him with a fly. I’d gone out pike fishing, bless you, never thinking of a trout, and when I saw that whopper on the end of my line, blest if it didn’t quite take me aback. Well, you see, he weighed twenty-six pound. ch 17
