Excerpt from Proceedings of the Royal Society of Victoria, Vol. 30: Parts I. And II., Issued September 1917, and March 1918, Containing Papers Read Before the Society During 1917 The differences between the width of the annual rings as the tree gets older will be less and less. There is a point of interest here, and that is that the enormous decrease in the width of the ring may be due to overcrowding, or putting it in other words, that as the trees grow older and so many are striving for the same light and carbon dioxide, that the crown it not as large as it would be if the forest were controlled. It was very apparent from a study of the mature trees that width of ring is largely dependent on the distance of the trees apart, for in many logs the original centre is well to one side of the mature log. Some trees have limbs on the congested side onlv 6 to 8 ft. Long, while on the free side they are 15 to 20 ft. Long. The maintenance of a good head is important from a forestral point Of view. In Fig. 2 the curve is given for the diameter at each decade. The curve is remarkably even, and from it one may deduce the age of a tree very approximately if the diameter (or girth) be known.
