Those trees which have gained this advauta.^e over their neighbors are called dominant trees, while the surviving lag- gards in the race are said to be overtoi^ped when they are hopelessly be- hind, and retarded when less badly beaten. Enor- mous numbers of seed- lings and small saplings are suppressed and killed during the early youth of the forest. In the young crop which we are fol- lowing many thousands I)erish upon every acre. Even the dominant trees, whicli are temporarily free when they rise above their neighbors, speedily come into conflict with each other as they spread, and in the end the greater portion is overcome. It is a very deadly strug- gle, but year by year the differences between the trees become less marked. Each separate individual clings to life with greater tenacity, the strife is more.
