The 1917 summer trip taken by the Ames forestry students was made through Iowa, Nebraska, Colorado, Utah, Nevada, California, Oregon, Washington, Idaho, Montana, North Dakota and Minnesota. The class was in the field for 12 weeks under the direction of 3 members of the forestry faculty. The students had an opportunity to observe the principal timber types in all the important lumber regions of western United States as well as to make detailed studies of logging and milling operations. During the trip 3 Forest Service Experimental Stations, several nurseries, and 14 National Forests were visited. The trip was made at a relatively small expense to the students. Camps were established at the different stops and, except in a few cases, meals were served in camp.
