Progress and Results in Malaria Eradication 



B'Y FREDERICK I.. HOF^MAN^ NEWARK, N. J. 



It is a highly apipreciated privilege on my part to be given an 

 opportunity of a;n active participation in this meeting. There is 

 no groitupi of men at the present time who' are rendering more use- 

 ful services in connection with malaria-eradication work than the 

 members of the New Jersey State Association. Although more 

 directly co'ncerned with malaria eradication, I have long since 

 come to realize the obvious practical importance of any and all 

 mosquitO'-extermination efforts. Personally, I am unequivocally 

 of the opinion that the former will never be achieved without 

 the latter, and that no' matter how many different methods of 

 malaria prophylaxis may be suggested or advocated, in its final 

 analysis any effort must fail tO' rid the community of malaria if 

 the Anopheles mosquitoes are not entirely done away with. You 

 may sterilize your carriers; yon may practice quinine prophy- 

 laxis ; you may screen your houses ; you may oil your ponds ; you 

 may spend hundreds of thousands of dollars for larvicides, how- 

 ever effective, but if you do- not dry up breeding pools, if you do 

 not drain the country, if youi do' not conform to the principles of 

 Ross, that there must be noi stagnant water, you will have the 

 mosquitoes, and as long as you have the Anopheles you will have 

 malaria. 



It has O'f ten been my intention to^ examine thoroughly intO' what 

 has actually been done in this state during recent years, but here- 

 tofore most of my field examinations have been limited to the 

 Southern States and tO' certain tropical countries where the 

 malaria problem is a matter of more serious concern than in 

 New Jersey. The five annual reports of your association are a 

 mine O'f useful, conclusive and constructive information. It, how- 

 ever, would have been an advantage if the results achieved had 

 been set forth in a more attractive and scientific way than has 

 thus far been considered necessary. For, after all, we are under 

 some obligation to other communities that the methods pursued 

 and objects attained by us shall be presented in a thoroughly in- 

 structive manner as an encouragement to the undertaking of
