Bids for the canal\'s construction were opened in January 1907, and Knoxville, Tennessee-based contractor William J. Oliver was the low bidder. Stevens disliked Oliver, and vehemently opposed his choice. Although Roosevelt initially favoured the use of a contractor, he eventually decided that army engineers should carry out the work. According to the book "The Panama Canal: An Army\'s Enterprise", Goethals made such an impression on William Howard Taft, then Secretary of War, that Taft recommended him as an engineer for the Panama Canal. Stevens, frustrated by government inaction and the army involvement, resigned from his position. In February 1907 US President Theodore Roosevelt appointed Colonel George Washington Goethals chief engineer of the Panama Canal.', 'In February 1907 US President Theodore Roosevelt appointed Colonel George Washington Goethals chief engineer of the Panama Canal.']}}]}, {'provenance': [{'wikipedia_id': '24849', 'title': 'Panama Canal', 'section': 'Section::::History.:United States acquisition.\n', 'start_paragraph_id': 25, 'end_paragraph_id': 25, 'meta': {'evidence_span': ['The treaty was ratified by the US Senate on March 14, 1903, but the Senate of Colombia did not ratify it.
