The food laid down or manufactured in the leaf is distributed over the tree through certain regions of "food ducts" which are located in the inner "; Thus in F'igure 13 we see in the cross cut of a basswood limb that the woody or water-carr)ing tissues are sur- rounded by certain regions of the "bark" (P) which are responsible for the distribution of food to the tree. It is a familiar fact that wounded animal tissue reipiires abundant food materials to repair and rebuild the injury. The food is supplied by the blood. In the case of plants, the food stream is distributed more slowly through fhi bark. It thus is evident that in r-etttoving a limb entirelx, if the the roots, their condition and develop- ment, the care with which the soil has been cultivated, and the character of the leafy top of the tree.
