The match began on Australia Day weekend 1879 between a touring Lord Harris XI and Australia. Spofforth, then 25, had missed the very first Test in 1877 over a wicketkeeper-selection dispute and made his Test debut in this game.
In England's first innings he ran through the middle order. The hat-trick fell on the second day: Royle was bowled, MacKinnon was bowled, and Tom Emmett — the Yorkshire fast bowler batting at number 9 — was given out lbw to make it three in three balls. Spofforth's match figures were 6/48 and 7/62. Australia won by 10 wickets.
It was the only Test match of the entire 1878-79 season, and the only Test Spofforth played for nearly two years (because of the 1879 Sydney Riot diplomatic fallout, which postponed the next Australian tour to England). The hat-trick was the start of Spofforth's habit of mid-innings devastation that would peak at The Oval in 1882.
The other detail: Spofforth's lbw to Emmett was given by umpire George Coulthard — the same umpire who, weeks later in Sydney, would precipitate the cricket riot.
