17th--19th rounds like the 7th--9th.
20th round: Alternately 1 treble with the light wool, 1 treble with the dark; but every treble stitch must be cast off with the wool of the colour of the next stitch; that is, a light treble stitch with the dark wool, and a dark treble stitch with the light wool.
