 ence, as to make it necessary to put " copy " into the hands of the printer, for each num- 

 ber, three weeks before date of issue. This should be remembered in sending special or 

 important matter for a certain issue. Twenty-five " extras," without change in form, 

 will be given free, when they are wanted ; and this should be so stated on the MS., along

Proceedings of the First General Convention to Consider the 

 Questions Involved in Mosquito Extermination, Brooklyn, 

 1904. This booklet has just been received and it shows the 

 rapid growth of knowledge in relation to this important subject. 



In 1889 Dr. Robert H. lyamborn became greatly interested 

 in the subject of mosquito extermination, and stimulated an 

 interest in the subject by offering prizes for essays along these 

 lines. The essays appeared in book form under the title 

 " Dragonfles vs. Mosquitoes. Can the Mosquito Pest be Miti- 

 gated ? ' ' During the fourteen years since the Lamborn essays 

 there has been an immense gain in knowledge which has ac- 

 crued mostly from the work of the medical officers in the 

 United States Army during the Spanish-American war. Great 

 good has also come from the efforts of Dr. John B. Smith in 

 New Jersey, who has demonstrated ways and means and care- 

 fully explored the possibilities and probabilities for the future, 

 and his survey of the State of New Jersey will be found very 

 valuable to workers in other places. The value of such studies 

 is almost incalculable. A single illustration will suffice. The 

 annual mortality from yellow fever in Havana has been nearly 

 2000 cases for forty years, or as far back as the record has been 

 kept. At the present time the disease is under control in 

 Havana and the mortality nil or trifling. Malaria and yellow 

 fever have lost their terrors, as we know how to control them, 

 and it is now only a question for municipal or State effort to 

 see that the appropriate measures are carried out or enforced.
