Division clubs. Not all of the First Division clubs fielded a reserve team due to the additional costs involved. In 1932-33 season they were joined by Beith, Galston and Bo'ness, who were unable to pay their opponents match guarantees. From 1920, it had a policy of including at least one non-reserve team. On the collapse of the Scottish Football League Third Division in 1926, a large number of clubs found a place in the Alliance. So much so that for one season the competition was split into regional sections. This split lasted only one season, after which the Alliance was amalgamated again into one division. In 1938, the First Division clubs decided to create a formal league for reserve teams, which meant that Beith and Galston had to be expelled because they were first teams. It also meant that Dundee's reserve team were expelled; as the club had been relegated from the First Division but had still maintained a reserve team in the Alliance.
