Excerpt from Scale Insects Injurious to Orchards: An Account of Some Scale Liable Insects Liable to Be Introduced Be Introduced With Shipments of Young Trees It is the intention in this publication to deal with a group of insects which have been the subject of numerous inquiries and have heretofore received no special attention in Kansas. The reason for this, doubtless, is that they have not been known to exist in alarming numbers in the state. While the present information upon the subject contains no knowledge of their presence within the state, it is not sufficient evidence of their absence. Other states believing them to be absent or present only within small limits have been surprised and alarmed when, upon investigation, they ascertain thje large areas infested and amount of damage done. At the request of the owners, I have examined a number of nurseries in this state and found no forms of injurious scale insects present. The statement of Prof. F. M. Webster, state entomologist of Ohio, that no scientist can be positive of the absence of isolated colonies without a microscopic examination of every twig, branch and trunk of the trees inspected, carries with it much weight. While I cannot assume that the state is entirely free from these scale pests, and while I do not desire to give cause for undue alarm, I can, however, say that from the experiences of other states Kansas is very likely to suffer from these, the most pernicious enemies of horticulturists, unless strict precautions are observed. Upon the principles, then, that to be forewarned is to be forearmed, and that a knowledge of prevention is more valuable than application of curatives, are based the reasons for this article. I am under many obligations to Chancellor F. H. Snow for valuable suggestions offered during preparation of this paper, to Hon. Jno, E. Frost, land commissioner of the Atchison, Topeka & Santa Fe railway, and Hon. E. R. Washburn, president of the Kansas City, Fort Scott & Memphis railway, for material assistance rendered in securing data upon this subject.
