The two volumes I've seen of Walsh's Compleat Country Dancing Master, 1718 and 1719, contained no lyrics whatever.
As can be seen the index of country dances tunes prior to 1730, at www.erols.com/olsonw, there is no tune called simply "The Triumph" in any volume of the Dancing Master. In other dance music collections prior to 1730 one can find, Ladys' Triumph, Love's Triumph, and Neptune's Triumph
