Note: This crib follows the current way of dancing. In the original instructions, the promenade [25-32] is cclw. Bill Hamilton said in 'hindsight' this promenade should be clw, but preferred not to change the official instructions. Bill disapproved of another variant, where the circle [121-128] is continued to the R only.
In 17-32, the corners traditionally set one bar to the person you just passed, then one bar to the next person to pass. In a variant for [19-24] 1c turns BH in PdB.
Dance is done 6 x 32, twice for each couple
Note: Cosh explicitly tells 1c to pass Lsh in [9-24]; however the Rsh pass is quite common, and nicknamed »Mairi's Divorce«.
