Newcastle United won the competition for the second time, beating Aston Villa 2–0 in the final at Wembley.
If scores were level after 90 minutes had been played, a replay would take place at the stadium of the second-named team later the same week.
37 Football League clubs joined the participating non-league teams entering this season's tournament in the qualifying rounds.
Another twelve Third Division clubs (Ashington, Hartlepools United, Barrow, Southport, New Brighton, Rochdale, Lincoln City and Tranmere Rovers from the North, and Southend United, Exeter City, Newport County and Aberdare Athletic from the South) were entered in the fourth qualifying round.
The remaining Third Division clubs, Durham City, Doncaster Rovers and Bournemouth & Boscombe Athletic were entered in the preliminary round.
Durham needed two replays to see off West Stanley before losing to Northern Combination outfit Dipton United, while Doncaster and Bournemouth (both newly elected to the Football League this season) withdrew from the competition after being drawn against Fryston Colliery Welfare and Portsea Gas Company respectively.
The final spot in the main draw went to Welsh Southern League club Llanelli, who were appearing at that stage for the first time.
