In a region studied this spring in South- ern Arkansas it was found that it took the average seedling only five years to reach a diameter of over an inch, and become fairly fire resistant, when grow- ing in open places. Seedlings growing in the forest under partial shade grow more slowly and may be killed by fire at 8 or 10 years of age. But the young trees which spring up on cut over areas would have plenty of sun and room and five vears would be enough to bring them to a fire resis- tant size. On longleaf lands, the fires are at present so frequent that seedlings do not have time to get by the first two years when they are small and ill pro- tected. If it were possible to keep fires out of an area for five years, these longleaf seedlings while still very short, —probably not over a foot high—would be an inch or more thick. Xone but a hot fire in dr}- weather could possibly kill them all at this stage. This fre- quency of fires is not a natural condi-.
