SHADE TREES ] NECESSARYTO

What a beautiful houseI" is an expression that seldom means just what it implies
 More often than not the visitor sees little or nothing Of the house a gable, perhaps, or a tiled roof or brick chimney. What the admirer really means is: "VVhat beautiful shade trees!" For shade trees first at tract attantion and give the impressi on of beautys spaciousness and sheltered comfort.
 Wherever man transplants a tree, he should make a sincere and sym pathetic attempt to understand the conditions which contribute to it's health.
 In it's natural forest environment, a tree has the benefit of sunshine and shade, moisture and humus, and a certain immunity against insect rav- . ages. Transplanted in a street or tpark, it loses these things and must Z Often a tree is planted in hard, pack ed soil which frequently is disturbed; !; sometimes it is poisoned by acids or noxious fumes and dust, and its sup l=pIy of water and light is matter of hazard. Under such conditions the tree loses it's resistant powers just as a man who has suffered an attack of fever. In it's weakened state, the tree is easy prey to the swarminS insect pests
 Man Can Fight Insects.
 Sometimes the adverse conditions can not be improved, but in this event man can lend his aid in fighting the insects and protecting his trees from injury. Farmers Bulletin, No. 1169, published by the United States De partment of Agriculture, outlines practical means for controlling most of the injurious shade-tree insects in the eastern part of the country. The insects which attack shade trees are roughly grouped into three classes; Leaf chewers, wood and bark borers, and Sap-Sucking.
 The Federal specialists explode favorite faIlacy, when they state thai methods for eXterminating insects which depend upon the injection or chemicals into the bark are absolute ly worthless. Money spent in buying such equipment is wasted The principle of bark injection is, pre- sumabIy, to introduce a poisonous material into the sap, so borers ana leaf eaters will be killed but the idea, plausible though it may seem, IS quite useless.
 The bulletin discusses the various poisons and the effective use of each, 4 the treatment of tree wounds, hlnng of cavities, pruning, stimulation or growth by the use of fertilizers, the use of implements in the care Of the trees, sprays and spraying equipment Another thory exploded is that the use of tree bands gives tree com Splete protection This idea IS heId by many people and has resulted m the indiscriminate application Of bands of all kinds. Many of the in sects, the bulletin shows, reach the trees by flying and the bands are no defense against them. Tree bands are effective in some cases and the specialists describe how they should be adjusted and of what materials they should be made.
 Illustrations Show Pests.
 The bulletin contains illustrations and descriptions of most of the shade tree insect pests which the eastern tree owner is apt to encounter. to- their presence. It is stated that the Bureau of Entomology, United States Department of Agriculture, in any case not covered in the Bulletin, will give through it's branch of For est Entomology, specific informatFOn on insects, insect injury and the rem edies to be applied
 In mailing samples of live insects and their work, the name and ad- dress of the writer should appear on the wrapper. The wood and bark borers should be left in their bur rows and the wood or bark cut into convenient sections and tied Leaf eating insects should be separated to prevent cannibaliSm and mailed in tin containers or mailing tubes. Under ground insects should be sent in earth and soft-bodied insects in al cohol. Leaves and small specimens of insect work may be mailed with the letter. All possible information resarding the character and extent of the injury, name of the tree or shrub, the locality where the insect was found, and the date of collection, should accompany the injury.
