The preceding discussion has concerned only poles which were grown and 

 cut in the northern Rocky Mountain area. Additional poles are imported from 

 Canada and the West Coast section of the United States and processed at yards 

 in this area (table 4) . Total imports in 1956 were 63 percent greater than 

 those of 1955. Western redcedar made up 80 percent of the total imports.

While most of the poles grown in the northern Rocky Mountain area are 

 processed within the area along with imported poles, a small number are 

 shipped to processing yards elsewhere. These outside yards, mainly in 

 Minnesota, received 16,216 poles (or 2.8 percent of the total 1956 production) 

 directly from the northern Rocky Mountain area.

 tain area by species, lengths, and American Standards Association class.
