13th to 16th inclusive: X knit 2, slip 2 as before, knit 1, X repeat
all round.

17th and 18th purled. Repeat these 18 rounds again.

Then do the same twice more; but, instead of knitting three stitches,
always decrease by knitting two together (once) on the needle
that has the thirty stitches in every row which is not plainly purled,
until only twelve stitches are left on it.

When 72 rounds are done, the boot will be sufficiently long. Purl two
rounds, divide the whole number of stitches on two needles, taking
care that the 12 stitches shall be exactly in the centre of one; then
join up the toe by casting off, knitting one stitch from each needle
together.

Now take up the twenty centre stitches of the 70 originally cast
on--that is, the twenty middle ones of the thirty that were on one
needle, and which were decreased to twelve. Knit them backwards and
forwards 40 rows. With another needle take up on each edge of this
plain knitting 20 more stitches, so that there are 60 altogether.

These stitches must be knitted backwards and forwards thus:--

1st row: X knit 3, slip 2 as before, X repeat with the last stitch,
take up one of the 70 next to the 20.

2nd: Slip 2, but as if you were going to knit plain, purl 3. Repeat;
join on to the 70 at the other end.
