In the midst of the astonishment produced by this seemingly prodigious
display of memory, say—“Now, if you like, we will have a hand at whist,
and I undertake to win _every trick_ if I be allowed to deal.” Let the
whist party be formed, and get the cards cut as usual—on taking care to
_replace_ them, as before enjoined, precisely as they were. Deal the
cards, and the result will be that your thirteen cards will be _all
trumps_. Let the game proceed until your opponents “give it up” in utter
bewilderment.
