Varilla attacked canal engineers

Varilla attacked canal engineers

Following his attack on the board of consulting engineers for the Panama Canal, Philippe Bunau-Varilla’s hopes of becoming an engineer on the project have been dashed. Bunau-Varilla had proposed first building a lock canal that would gradually be dug into a sea-level canal; this plan was rejected as extravagant and unfeasible. Current plans are for a sea-level canal to be dug, which will take fifteen years and cost $230,000,000.

The Panama Canal from a contractor’s standpoint

The Panama Canal from a contractor’s standpoint

In this journal article, George W. Crichfield proposes a plan for the completion of the Panama Canal. He begins by describing the environment of Panama and the current plans suggested by Admiral John Grimes Walker and the Isthmian Canal Commission before dissenting from these opinions due to his studies of the canal in January and February. Crichfield believes the canal should be divided into sections that are bid on by different contractors, as he does not think the Panama Canal should be in the hands of a single corporation. Based on his calculations, he recommends fifty-eight separate contracts. Crichfield also recommends that the canal is a tide-level canal rather than a lock canal. He disagrees with Brigadier General Peter C. Hains that African Americans are the best laborers for the job and instead recommends using people from the area. Crichfield encourages the government to guard against red tape and suggests the construction of the canal should be as serious as the prosecution of war: “The sooner it is finished the better.” Crichfield believes it is better to spend more and finish sooner than to spend less money but more time.

Letter from William H. Taft to Theodore Roosevelt

Letter from William H. Taft to Theodore Roosevelt

Secretary of War Taft sends President Roosevelt a letter he received from Theodore P. Shonts, Chairman of the Isthmian Canal Commission, with a resolution from the commission widening the locks of the canal from 100 feet to 110 feet. While this will increase the cost of the canal and slightly reduce the capacity, Taft agrees with this decision in order to accommodate future ships, which will likely require the wider space.

Notes of progress

Notes of progress

President Roosevelt, in his annual message to Congress, praised the work that has been done and continues to be done on the Panama Canal. Many newspapers have published sensational articles alleging problems with the Gatun Dam in Panama, but these articles are contradicted by the facts, as the dam has not been constructed yet, and the work which has been done on it has been going smoothly.

Letter from Theodore Roosevelt to William S. Cowles

Letter from Theodore Roosevelt to William S. Cowles

Governor Roosevelt encloses a document from an Oyster Bay, New York, neighbor who has questions regarding what circumstances would allow his discharge. Roosevelt is confused over Secretary of State Hay’s and President McKinley’s views on the canal treaty. If such a canal as they suggest existed during the Spanish-American War there would have been a great deal of anxiety over the Spanish fleet using the canal to attack the Pacific coast or Admiral Dewey in the Philippines. Roosevelt wants a canal held and fortified by the United States.

Letter from Theodore Roosevelt to William S. Cowles

Letter from Theodore Roosevelt to William S. Cowles

Governor Roosevelt believes that the proposed canal should be fortified. If it is not, the canal would be another weak point to watch over during a conflict. If the canal had existed during the Spanish-American War, American forces would have needed to defend the canal to prevent the Spanish fleet from crossing into the Pacific Ocean and causing problems in a new theater. Roosevelt also favors an American canal as he does not want to see European powers gain new interests in the Americas.
