Question: Passage: By the 1920s, SCGX was doubling annually and had emerged as the "fastest growing grain market in the world"; transacting 22 million bushels in 1928 (valued at $336 million in 2018), resulting from its location in the heart of the Corn Belt and self-imposed standards before the Grain Standards Act of 1916 including species admittance and non-mixing. However, its growth was limited by shipping rates. With the trucking industry and Interstate Highway System not yet developed, SCGX was constrained by monopolized railroad rates, primarily by the Great Northern Railway. Exhausting their bargaining power with the Interstate Commerce Commission, SCGX President Charles C. Flanley directed future lobbying efforts to unlocking barge navigation of the Missouri River. His initiative was stalled throughout the 1930s by the Great Depression and Dust Bowl. In 1938, a renewed thirteen year campaign led by Secretary William Henry Marriott finally opened commercial navigation of the Missouri River and helped establish the Missouri River Basin Project, which included development of the Gavins Point Dam. The alternate transportation succeeded in breaking the railroad's monopoly. By the 1970s, SCGX was among the largest exchanges in the world; transacting over 100 million bushels annually (valued at $1 billion as of 2018).

He moved on to join Irish side Drogheda United, helping them defeat Athlone Town 3–1 at Tolka Park on 5 January 1984 to lift the League of Ireland Cup. Gallagher returned to Wisbech Town for the 1984–85 season before rejoining another of his former clubs, Peterborough United, in August 1985. His second spell proved his strongest in league football, as he netted 24 goals in 82 league games, earning a move to Wolverhampton Wanderers in June 1987. He found opportunities limited at Molineux due to the prolific partnership of Steve Bull and Andy Mutch, but did play at Wembley in their victory in the Sherpa Van Trophy in May 1988. He was loaned to both Wisbech Town and Kettering Town during the following season before being released in September 1989, and joining Conference side Boston United.
