Oeejssteix (Dr. A. J.). Mosquito Catching in Dwellings in the 

 Prophylaxis of Malaria. — Amei-. Jl. Puhlic IJenlfh, iii, no. 2, 

 February 1913, pp. lOG-110. 



Catching mosquitos by hand is an extremelj' valuable measure 

 in the prophylaxis of malaria, especially in temporary camps. 

 In the Panama Canal Zone, West Indian negros, with very little 

 training, performed this work satisfactorily for 10 cents an hour. 

 It is advisable to have the dwelling well lighted and the walls 

 painted a light colour or whitewashed. In screened buildings 

 hand-catching may be supplemented by properly designed and 

 installed mosquito traps. A six-inch square wire gauze attached 

 to a two-foot stick makes an effective mosquito ' slapper.' This 

 and a bottle 4i inches long and 1 inch in diameter, containing 

 rubber bands cut into short lengths packed into a layer about 

 an inch thick and kept in place by a plug of cotton wool 

 soaked with a few cc. of chloroform, is all the equipment needed 

 by the negro fly-catcher. Having spied an Anopheliue the catcher 

 uncorks his bottle and gently but rapidly places it over the 

 insect, which is overcome by the chloroform fumes and drops 

 into the bottle. 



Quarantine for Texas Fever of Cattle.-— L'.^S'. Dept. Agric, Bureau 

 of Aiiii/taJ Industiij, 1st March 1913. 



The United States Bureau of Animal Industry has issued a 

 map showing the counties in each State against which quarantine 

 is exercised for Texas fever of cattle. The States involved are : — 

 Florida, practically the whole of Georgia and Alabama, the 

 greater part of Mississippi and Arkansas, the whole of Louisiana, 

 the greater part of Texas and Oklahoma, large portions of South 

 Carolina, about half of North Carolina and G counties of Virginia, 

 and also practically the whole of the southern half of California. 



Texas fever is spread by the species of cattle tick known as 

 Marrjaropus annulatus. Since 1906 the Federal Government and 

 State and local authorities have been engaged in co-operative 

 work for the extermination of these ticks. The boundary of the 

 tick-infasted territory at the time of the beginning of this work, 

 and the areas freed from ticks and released from quarantine as 

 ;a result of the progress so far made, are indicated on the map.
