This is a Highland-style sword dance for two dancers. It consists of 3 steps in strathspey tempo (16 bars each, with the 3rd step being repeated, for a total of 64 bars) and one reel step (40 bars).  March music is stipulated to enter and exit.  
The dance was collected and revived by Mrs MacNab in Ontario, Canada, in 1917.  It was published in 1961 in a leaflet by her niece Mrs Elizabeth Sutorius for her aunt.
