their natural enemies whenever these are available. But in 

 the case of injurious insects for which the natural check has 

 not yet been secured, we cannot know too much about their 

 habits and life history. A complete knowledge of these facts 

 can alone reveal to us a loophole through which we can man- 

 age to bridle their ravages by cultural or artificial means. It 

 is with the object of discovering these loopholes that we study 

 the habits of injurious insects. There is still much to be dont: 

 in this direction. 



HOW WE HELP FAEMEES AND PLANT GEOWEES. 



As already stated, when beneficial insects are available 

 these are always supplied to applicants. When these are not 

 to be had, however, we are able, in the majority of instances, 

 to offer good advice, or prescribe efficient remedies. Thanks 

 to the good work of Mr. Koebele we have on these Islands 

 a good supply of most useful insects. At all time some of 

 these are to be had in some place. Honolulu is excellent 

 breeding ground for all of them, and we always have an eye 

 on the places where certain species of these are to be pro- 

 cured, if we do not breed them in the laboratory. And thanks 

 to the efforts of American entomologists wc know of a number 

 of standard remedies that are efficient against various insect 

 pests. Either beneficial insects or prescriptions for remedies 

 it is our duty to supply to our correspondents. 



When our knowledge and farmers' needs warrant it we 

 shall publish bulletins or circulars from time to time giving 

 information on various insects or groups of insects. It is our 

 belief that farmers ought to know enough about their insect 

 enemies to be able to forestall serious damage by prompt and 

 intelligent application of preventives. This kind of knowl- 

 edge we hope to impart in our future publications. This, our 

 first one, is of the nature of an introduction, and we hope will 

 in a way prove useful to the farmer and home owner.
