I. FOREST TREES. 
1. Hemlock (Pinus canadensis ). 
Tree sound. Diameter five feet from the base, 25 inches. Average thickness of the bark about one inch. 
Half of the diameter was produced during the last fifty years growth : these 50 outside layers were 
taken for outside wood; and the remaining layers, 154 in number, for inside wood. Whole number 
of layers five feet from the 
ground, 204: aver 
age thickness of each layer,
