a Measurements made by E. T. Allen in western Washington, 1899, and by a 

 Forest ofTicer (name not reported) near Dee, in the Mount Hood region of Oregon, 

 1907; supplemented by measurements on a number of rather large trees by one of 

 the authors on the west base of Mount Rainier, in 1907. Long logs were scaled a^ 

 two short logs, using 16-foot lengths as much as possible.
