Abstract
If one cuts down a tree, branch, or leaf, the weight of the whole part cut off, w gm., bears a relation to the circumference, c cm., measured at the point of section of the part cut off. The observations when plotted lie close to a line, the equation of which is log w=2.49 log c+0.85. A corollary of this fact is that when a stem, with circumference Co divides into 2 branches, C1 and C2, the following law tends to hold: Co 2.49 = C 12.49+C 22.49. The bearing of these norms on the angles of branching is discussed mathematically.This publication has 0 references indexed in Scilit:
