her; and lay them on this third one. Look again and carefully;
and, if another of the Suit be found, carry to it the former ones. So
do until you have no more of its Suit toward its left, to join unto,
and until all the cards of one Suit in the Row lie piled together;
save the _Master-Card_, which even if it be of the Suit lieth alone,
leftward, as it was first dealt out and down, in the last Square.

Of the _Reduction_.

Proceed then with the next Suit in the Row: and so with each Row,
until you have thus sorted all the cards save the Master-Cards.
This is the _Reduction_.

Close now and straiten-up together each of the Rows thus broken
into Piles; pushing ever toward the _Master-Row_. Thus have you
a new Figure, smaller than the last Square of Sevens, and
somewhat irregular: there be in some Rows five cards, in others
less; even so few, though rarely, as three or two. Note that a Pile
of Cards is reckoned only as one card. Note, too, that with cards
that have become hid beneath others you have no concern.

Of the _Sacrifice_.

Next, cast or lay aside in a parcel, all Cards in the Figure that are
not contained in the three Columns, leftward (the _Master-Column_,
and two other Columns). If, your _Reduction_ done, any Row offer
to sight but two Cards--the _Master-Card_ and its neighbor--so
must the Row abide. But this comes rarely. You will best not
disturb the Cards hid in the Piles, for it is well to let
Sleeping Dogs lie, and moreover needless Fingering and Quiddling
of the Parallelogram is not commended. With the cards thus
rejected have you no more to do. They are called the _Sacrifice_.

The _Parallelogram_ made.

Now have you a _Parallelogram_ of One-and-Twenty Cards in
sight (Fig. 13), reduced from the Square that for
