ANALYSES OF THE ASH OF FOREST TREES. 



II. ANALYSES OF THE ASH. 



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: average thickness of each layer, 0-05637 of an inch.

2. Sugar Maple (Acer sacchari?ium). 

 Tree sound. Diameter three feet from the ground, 28 inches; do. twelve feet from the ground, 211 inches. 

 From the base to the limbs, 62 feet. Whole length of the tree, 107 feet. Average thickness of the 

 bark, f inch. Age 224 years. At twelve feet from the base, the 100 outside layers were taken for 

 outside wood, making a thickness of 4| inches; the remaining layers were taken for inside wood. 

 Growth very uniform. Average thickness of each layer, 0-04464 of an inch.
