the two last intakes, purl together the 4th and 3rd
stitches before the end of the 1st and 3rd needle, and the 3rd and 4th
at the beginning of the 2nd and 4th needles.

12th, 15th, and 18th rounds--Decrease, the same as in the 9th round.

21st round--knit 2 plain, at the beginning of the 1st and 3rd needles;
knit the next 2 together; knit together the 4th and 3rd, before the end
of the 2nd and 4th needles; knit the last stitches plain; go on
decreasing in this way until the purled stitches meet. After the plain
round over the intakes, add four plain rounds, divide the stitches that
remain for the sole, on two needles and cast off on the wrong side.

Now take up the auxiliary stitches, and in the first 3 plain rounds,
knit together the last and the first of the 1st and 2nd needles, and the
last and the first of the 3rd and 4th.

With the rest of the extra stitches make purled intakes, knitting two
plain rounds after each round with an intake.

For the other kind of plain heel also (fig. 360), auxiliary stitches are
required. Supposing that you have 20 stitches on each needle, you must
cast on 28 stitches on to each auxiliary needle; knit together the 4th
and 3rd stitches at the end of the 1st and 3rd needles, and the 3rd and
4th of the 2nd and 3rd needles, so that you may have 4 plain stitches
between both intakes. Go on decreasing, knitting 2 plain rounds after
each round with an intake, until you have 6 stitches left on each
needle. Then knit together the first and last stitches of each needle,
one plain round over it, and finish with a chain on the wrong side of
the heel. Then take up the auxiliary stitches and knit the instep.

ITALIAN STOCKING (fig. 361).--The heel, sole and toe of a stocking
always wear out before the instep. The Italians and Greeks economise
time and material and facilitate the renewal of those parts that wear
out, by knitting the upper part of the foot in two pieces. After
knitting the heel in on or other of the above ways, work the foot as
straight knitting with the two upper needles only, until you have the
necessary length. Then knit the underneath part separately, in the same
way. You must keep a chain along all edges and a narrow seam of one or
two stitches. In the sole, which you make after finishing the upper
part, you intakes must come directly after and before the seam. When you
have got the same number of rounds in each piece, join them together and
begin the toe.
