The tournament took place from 29 September to 1 October. The first day consisted of 36 holes of stroke-play. The leading 8 qualified to play in the match-play on the following two days. The weather was wet and windy on the first day and J.H. Taylor led the qualifying with rounds of 78 and 86, 2 strokes ahead of Sandy Herd. Taylor's round of 78 earned him £5 for the best round of the day. Harry Vardon had rounds of 84 and 87 and finished tied for 6th place.[1] The weather on the second day was much better.
