Forests and forestry. 164 ELEMENTS OF FORESTRY The methods of studying diameter growth and volume growth were touched upon in connection with stem analysis, but the study of the growth of a single tree is of minor im- portance in comparison with the volume growth of Fig. 30. — Studying the Growth of Beech in the Catskill Mountains. A crew is at work making a stem analysis to determine the rate of growth. A large number of trees are felled and measured and the data averaged together.

A crew is at work making a stem analysis to determine the rate of growth. A large number of trees are felled and measured and the data averaged together. As previously described, the volume growth or increment of a single tree may be ascertained by computing its contents and comparing them with the contents of the tree ten, twenty and thirty years ago, but this method involves a maximum amount of computation and is chiefly valuable in scientific Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Moon, Frederick Franklin, 1880-1929; Brown, Nelson Courtlandt, 1885-.
