Growth and Form Development II ing in diameter by additions, grows into a branch; new branchlets start from buds along the length of the mother shoot, the daughter shoots forming side branches, and by repeated ramifications, gradu- ally from year to year, the crown is built up, character- istic in form and following well-known laws, typical for each species. One important fact to be ob- served in this process of build- ing up a crown is, that not all the buds which are formed on the twig develop into shoots; some remain undeveloped or dormant as buds, some are frozen, some dried up, some eaten or broken off; and even of the shoots which have been developed not all grow into limbs or branches: many are lost sooner or later by causes similar to those which destroy the buds, and by the with- drawal of light and food, as the upper portions of the crown develop and cut off from the less favorably placed portions the necessaries of life. Just as in the animal world the struggle for existence necessitates.
