The problem which had to l)e met by these treeswas to maintain the extensive system of uninjured roots andbranches with almost no leaves until new ^Towth could providethe leaf surface necessary to feed the rest of the plant. Thecapacity shown by some of the trees of adjusting themselves tosuch abnormal conditions is remarkable. The most extremecase was found on Soluka Creek where a tall poplar was deadexcept for a very few twigs in the to]). (See page 192.) Thebark of this tree, wdiich was 41 inches in girth, was dead alongtwo strips 6 and 4 inches wide, leaving two bands of living bark15 and 16 inches wide and 40 to 50 feet high to be supported byonly the handful of leaves at the top.
