SCIENCE 



[N. S. Vol. XXVI. No. 675 



as pointed out thirteen years ago, it fre- 

 quently happens that compiled bulletins 

 have a greater practical value to the con- 

 stituency of the state experiment station, 

 than the bulletins giving the results of 

 original work. The original work bulletins 

 advance the condition of the science; the 

 compiled bulletins extend the knowledge of 

 the results so as to make them more valuable 

 to people at large. The work that has been 

 done by the offices of the different state 

 entomologists has been of the greatest value 

 —Forbes, in Illinois, and Felt, in New 

 York, have published material of the great- 

 est value. It would be perhaps invidious 

 to point out with any relative estimate of 

 their value any of the many highly impor- 

 tant publications that have been issued by 

 the entomologists of the experimental sta- 

 tions ; but the work done by Smith, in New 

 Jersey, and that which he has under way 

 in his large scale campaign against the mos- 

 quitoes of that state are of such a unique 

 character that they force special mention. 

 The mosquito destruction measures carried 

 on by English workers, and especially by 

 those connected with the Liverpool School 

 of Tropical Medicine,- in different parts of 

 the tropics controlled by England, has been 

 large scale work of great value. That done 

 by the army of occupation in Cuba was of 

 enormous value, so far as the city of Ha- 

 vana was concerned, and an assistant just 

 returned from the Isthmian canal zone as- 

 sures me that it is possible to sit now out- 

 of-doors of an evening upon an unprotected 

 veranda anywhere in the zone without be- 

 ing annoyed by mosquitoes, and without 

 danger of contracting malaria or yellow 

 fever. 



These are all great pieces of work, but 

 when we consider the condition that exists 

 in the state of New Jersey, and the inde- 

 fatigable and successful work of Smith in 

 the handling of the most difficult problem of 

 the species that breed in the salt marshes. 



and of his persistent and finally success- 

 ful efforts to induce the state legislature 

 of that wealthy but extremely economical 

 state to appropriate a large sum of money 

 to relieve New Jersey from its character- 

 istically traditional pest— we must hold up 

 our hands in admiration. 



The work that has been done by the state 

 entomologists, and the entomologists of the 

 state agricultural experiment stations, as a 

 whole, impresses one as being of the highest 

 practical value. "VATiile admirable pieces 

 of scientific investigation have been carried 

 out, the main fades of the work as a whole 

 is almost rampant with practicality. The 

 present condition of our knowledge of in- 

 secticides and systems of inspection is due 

 for the most part to these workers, and the 

 reading of the reports of the meetings of 

 the Association of Economic Entomologists 

 can not fail to impress one, not only with 

 the earnestness and vivid interest of these 

 men in their work, but also of their entirely 

 competent grasp of the subject. 



The speaker has visited personally many 

 of the European workers in economic ento- 

 mology during the past five or six years, 

 and everywhere has heard eulogistic com- 

 ments upon the work of the experiment- 

 station entomologists of the United States. 

 Sigismond Mokschetsky said to me last May 

 at Simferopol, in the Crimea: "I know 

 them all— Slingerland, Smith, Forbes, Felt, 

 Webster, Osborn— what men!" 



OTHER COUNTRIES 



In most of the other countries of the 

 world conditions are so different from those 

 in the United States as to call for a treat- 

 ment differing in some degree, greater or 

 less, from that found available in the 

 United States. Many of the principal in- 

 sect pests are cosmopolitan; many are so 

 similar in their habits as to allow the use 

 of identical or similar remedial measures. 

 In each separate faunal zone, however, are
