ceased to be rkre, it Ij^^azi to increase its damage^ so raudh that the turpentine 

 industry was threatened. To save the "businebsl turpentind produoetfe have 

 been iorced to rnalce narrowel* cuts in tapping for tumpentine so as to give 

 the borers less chance to get beneath the bark. 



A sonewhat different case is that of bark beetles in the Uest, Bark 

 beetles are one of Nature's aids in making away with the mature trees. In 

 our western forests we have over-mature timber which man wants to protect 

 and keep until it can be utilized. 



To do that, we must fight bark beetles constantly. Bark beetles each 

 year Icill off 18 to 20 million dollars worth of our timber. 



On the other hand, efforts to introduce trees in the sand-hill 

 region of Nebraska where there were no trees have brought a string of 

 troubles aind a continuous fight with one insect after another. Dr. Craig- 

 head sa:'s that in trying to grow trees on areas not well suited to trees 

 we cut out for ourselves a tough job. 



One of the v/ays to practice forestry is to fJllow nature's way of 

 growing trees. Grow the same sort, in the same mixtures, and under the same 

 conditions as nature grows them. Bureau of Entomology specialists are now 

 working v/ith U.S. Forest Service experts in finding out how nature does it. 



You see, insects are a very important part of that manner of living 

 we call a forest.
