On [7-8] 1W+2M originally passed Lsh, but the deviser changed this to Rsh.
Note: The dry white sands on the north-west side of the Isle of Eigg are said to produce a musical sound when walked upon.
Note: Cosh explicitly tells 1c to pass Lsh in [9-24]; however the Rsh pass is quite common, and nicknamed »Mairi's Divorce«.
