he collapsed because of an attack of angina pectoris. After three weeks recuperating, he returned to Washington against medical advice to resume his work. Following the death of Justice Horace Harmon Lurton, Lane was considered a possibility for elevation to the Supreme Court; however, Wilson chose another member of his cabinet, James Clark McReynolds. As Interior Secretary, Lane was responsible for the territories, and advocated the development of the Alaska Territory. While private railroads had been established there, they were not successful, and he pushed for a government-built railroad, which he believed would lead to large-scale population movement into Alaska. In 1914, Congress passed a bill authorizing construction of the Alaska Railroad, which passed the Senate following a two-day speech in support by Walsh. Lane was the first Interior Secretary to appoint an Alaska resident, John Franklin Alexander Strong, as territorial governor. Secretary Lane's vision for the territory was, "Alaska should not, in my judgment, be regarded as a mere storehouse of materials on which the people of the States may draw. She has the potentialities of a State. And whatever policies may be adopted should look toward an Alaska of homes, of industries, and of an extended commerce." Despite his role in the Hetch Hetchy controversy, Lane was friendly towards the National Park movement, and in 1915 hired Stephen Mather to oversee the parks for which the Department was responsible. Mather, a self-made millionaire and member of the Sierra Club, had written Lane a bitter letter in late 1914, complaining that the national parks were being exploited for private profit. Lane was intrigued by Mather's letter, made inquiry, and found that Mather was well thought of by Lane's friends—and had, like Lane, attended the University of California. Mather's advocacy led to the establishment of the National Park Service in 1916. In 1915, Lane returned to San Francisco to open the Panama-Pacific International Exposition. The President was supposed to open the fair, but was unable to attend, and sent the Interior Secretary in his place. In 1916, Wilson appointed Lane to lead the American delegation and meet with the Mexican commissioners at Atlantic City, New Jersey about the unstable military situation in Mexico. These negotiations led to the withdrawal of United States troops from Mexico. The Interior Department had never had a central headquarters, but had worked from offices scattered across Washington, with the bulk of the department located in
