The truth about this much despised creature is that he is useful as a warning against unclean conditions, and his odor and his bite are his notes of warning. Instead of filling one's self with a feeling of repulsion or anger or any other emotion that affects the free circulation of the blood, and relaxes and disorders the tissues of the body, at sight or mention of a bedbug, the discovery should elicit the expression, "Thank you for the information." If it should happen in one's own house, no hidden crack nor corner should escape an overhauling to get rid of the cause of the bedbug's warning; or, if it should happen in a hotel, there should be a change of hotel. Mention is made of mosquitos and roaches and bedbugs in this connection, not for the purpose of degrading the feeling of love by applying it to things that are disagreeable, no matter what their mission of usefulness, but to put stress upon the fact that one cannot afford to hate anything. It is especially useful, in seeking to change the point-of-view, to consider the greatest of causes of repulsion in order to more easily reach the lesser causes, for the lesser fade of themselves by the removal of the greater. If you can learn not to hate a bedbug, to thank a roach for informing you of unclean conditions and to endure mosquitos, you are pretty sure to modify all prejudices by thus doing. LAST SOMETIMES FIRST. It is my own habit to read the last chapter of a book first and if the summary of its contentions and deductions, which are sure to be found in the closing chapter, interest me, I go carefully through the book with the author to learn how he has reached his conclusions. I find, upon enquiry, that many others do the same. This is made necessary because of the vast number of books that are published and the impossibility of learning by other than the easiest means more than a small proportion of the ideas that are given out each year. There are published, yearly, in English, twenty to thirty thousand volumes of new matter, or new arrangements or new editions of old matter, so that to read carefully only a catalogue of them would be a considerable task for the ordinary reader. This being the closing chapter of my book, and being especially possessed of my subject and desirous of being understood, I may be pardoned for offering a brief syllabus of my effort as a benediction.
