apart, were used by detachments of soldiers throughout the year as they stayed watchful for wildfires, vandalism and poaching. The use of remote ranger cabins for patrolling the park is still practiced by Park Rangers. Captain Young, during his first tour as Acting Superintendent in 1897, established patrol cabin policies that are essentially still followed by Park Rangers. Young required that soldiers using a patrol cabin keep a daily log of activities, including game counts, visitor counts and weather observations. These logs were used to compile a monthly report sent to the headquarters at Fort Yellowstone. Young issued the following orders to all soldiers using the snowshoe cabins. Wildlife policies Of the many decisions made by Captain Boutelle in managing the park, his approach to fisheries had significant and lasting impact. Boutelle was an avid angler and recognized the angling potential in Yellowstone waters. In 1889 he suggested the U.S. Fish Commission consider stocking many of the fish-less lakes and streams in Yellowstone. This suggestion was acted upon and in 1889 the first non-native fish were stocked into Yellowstone waters, a practice that continued until 1955 and helped create the angling experience Yellowstone National Park is renowned for. In 1902, the population of bison in the park had declined to approximately 25 individual animals. Under the leadership of Captain Pitcher, the army began a program of importing plains bison from private domestic herds in Texas and Montana. Fenced enclosures were created at Mammoth and in the Lamar Valley. Areas were ploughed and planted with oats and timothy to feed the captive bison herds as well as the expanding elk herds. The bison enclosure in the Lamar Valley became known as the Lamar Buffalo Ranch. When the army left the park in 1918, the bison population was estimated to have increased to 400 individuals. Transition to the National Park Service After serving more than six years as the Acting Superintendent, Major John Pitcher was replaced by Lieutenant General Samuel B.M. Young (U.S. Army retired) in June 1907. Young was appointed by the Secretary of the Interior, James Rudolph Garfield as full superintendent of the park. Although Young was a senior officer, command of the troops at Fort Yellowstone was given to Major H. T. Allen. Young's lasting contribution to Fort Yellowstone's history was his proposal to replace the army with a force of Civilian Guards. Young, who had served as Acting
