cy, and request—(1) that the Michaux Fundand its accumulated income be annually expended in carryingout so much of the suggested plantings as that small sum maypermit, and (2) that the forestry appropriation be increasedsufficiently to enable the necessary pruning, thinning, andreplanting to be carried out in an energetic and consecutivemanner. The first step should be to extend the life of the presentlarge trees in every possible way. The most vital points arethe roots, which are nearly all close to the surface, seldomextending far into the ground, as may be observed when alarge tree is uprooted in a storm. Upon the surface fertilityof the soil a hard-wood tree largely depends, and when thehumus is deepest, a hard-wood forest will thrive best. Bychecking the forest fires and preserving a thick undergrowthwe could do much to produce this condition. Renewed vigorcan also often be obtained in failing trees by heading them in.This is particularly true of the White Oak. The following 24

Oyster-shell scale has damaged these Walnut trees almost beyondrepair. Careful pruning and spraying for several consecutive years Ibelieve will stiU save them. These sprayings will cost approximately 75cents per tree each time. 25 scale insects are also now playing havoc with the forests:oyster-shell.scale, green oak scale, and San Jose scale. Theoyster-shell scale is now doing most damage, infesting par-ticularly Beeches, Walnut, Sour Gum, and Red Maples.

Fortu-nately, it confines its attacks to the forms of White Oak alone,and we can by spraying keep it vmder control. Wlien thetrees are standing in o))en groves, as at Snyde
