The title "Panama Canal Open For Business 1914 - Cargo Ship" refers to the opening of the Panama Canal in 1914, which allowed for the efficient passage of cargo ships between the Atlantic and Pacific Oceans. The title suggests that the canal was now fully operational and ready to serve the shipping industry, and that a cargo ship is one of the many vessels that would be able to utilize this new trade route. The opening of the canal was a significant event in world history, as it greatly reduced the time and cost of transportation between the two oceans and had a profound impact on global trade and commerce.
