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).
Link Information: The dam and hydroelectric power plant were constructed as the Gavins Point Project from 1952 to 1957 by the United States Army Corps of Engineers as part of the Pick-Sloan Plan Question: When was the dam that was part of the Missouri River Basin Project completed?

Passage: The Abana was sailing from Liverpool to Savannah, Georgia when she was caught in a storm in the Irish Sea. She was spotted at 3 pm drifting in a northwesterly direction with her sails torn to shreds. The crew mistook Blackpool Tower for a lighthouse and the ship was first spotted foundering at North Pier, and ended up drifting north and was wrecked off Little Bispham at 5 pm. Flares were fired and the lifeboat was called out. The alarm was raised by the landlord of the Cleveleys Hotel. Due to the weather conditions, the Blackpool lifeboat Samuel Fletcher had to be taken some overland to Bispham before it could be launched. The lifeboat had a crew of 16, and the Abana had a crew of 17, all of whom were taken on board along with the ship's dog, which belonged to Captain Danielson. The lifeboat grounded on a sandbank whilst returning to shore, but some of the crew members pushed the boat afloat and they managed to reach shore safely. All were taken to the Red Lion Inn to recover from their ordeal. The ship's bell and dog were given to the landlord of the Cleveleys Hotel, who had raised the alarm.
