 ville, Bull 158, December 1918, pp. 55-56. [Received 12th 

 September 1919.] 



The tick eradication work in 1918 covered an area of 35,146 square 

 miles. The area under quarantine for the year under review was 

 reduced to 18,897 square miles from the 33,669 square miles quaran- 

 tined in 1917. The work included the use of 3,509 tanks through 

 which 91,247 herds were passed, making a total of 3,227,170 of cattle 

 dipped. 



Tick Eradication Laws. — Arkansas Univ. Agric. Exp. Sta., Fayette- 

 ville, Bull. 160, 1919, 14 pp. 



The tick eradication laws of Arkansas since 1899 are reviewed, 

 including ordinances regulating the movement and transportation 

 of live stock, regulations for the prevention of contagious diseases 

 among live stock and for the eradication of ticks, and a proclamation 

 made in 1918 to include certain districts in the quarantine area. 

 Several new rules and regulations have been made with regard to 

 the infested and special quarantine area, to become effective on and 

 after 1st March 1919. Formulae for self-boiled arsenical dips are 

 appended.

The bulk of the information contained in this paper has been 

 previously noticed [see this Review, Ser, B, vi, p. 168]. During the 

 past three years investigations have been made to ascertain the 

 effects of large bodies of impounded water on the incidence of malaria. 

 Much work has also been done to spread information about malaria 

 and its control among the public, great importance being attached 

 to this.

The practice of dipping cattle for tick control is growing in favour 

 in Jamaica. A 2 per cent, solution of arsenious oxide used at a two 

 weeks interval has proved most efficacious. Weaker solutions may 

 be used at shorter intervals, i.e., "08 at three-day and '16 at seven-day 

 intervals. Where hard water is used, it is recommended to increase 

 the quantity of Paranaph from 3 to 3-| lb. for each 2 lb. of arsenite 

 of soda, thus reducing the risk of injury to the skin. 



Ox warbles, Hypoderma hovis, were found on cattle imported from 

 the United States during the previous autmnn, but the pest was 

 kept under control by the systematic application of dressings.
