There had been revision bills in Congress for many years. In 1892 Senators Sanders of Montana and Warren of Wyoming introduced bills to increase Yellowstone by about one-third, adding areas on the south and east, but excising areas on the north and west to leave the park entirely in the state of Wyoming, and cutting off a corner

on the north for the Cinnabar-Cooke City railroad. This was really a mining railroad bill, and Senator Vest of Missouri promptly opposed it, but it passed the Senate and was favorably reported by the House Committee on Public Lands, but got no further. In the debates, Senator Berry of Arkansas urged that the park be divided into 160-acre tracts or sold as a whole, since it was only "a playground for the rich."l

In 1916 Horace Albright, assistant to Mather, made an inspection of the Yellowstone region with a party of leading citizens and on this trip he was so impressed with the Grand Teton and Jackson Hole region that he resolved to make it a part of the national park system. He had no idea what a long-drawn task this would be, but he never gave it up as long as he was in the Park Service. At the time, Senators Warren and Clark and Representative Frank Mandell were favorable to the project. Two years later Albright again visited Jackson Hole, and found many friends of the idea of giving it park status. A little later, at Mandell's request, Chief Forester Graves visited the area and he and Mather and Mandell agreed on an extension of Yellowstone to include the headwaters of the Yellowstone and Thorofare rivers, the Grand Teton Mountains, and the part of Jackson Hole north of Buffalo Fork. Mandell introduced a bill to achieve this, which passed the House but was objected to in the Senate by Senator Nugent of Idaho, who thought the west line of the park would extend all the way to the Idaho line and cut off Idaho sheep range. In the next Congress Mandell tried again, but failed.2
