of 47 and 35 respectively, 30 died within two weeks, many of the 

 remainder showing symptoms of sickness. Post mortem examination 

 revealed the presence in the digestive tract of a continuous string 

 of undigested matter largely composed of a fine, wool-like fibre enclosing 

 bits of grass, barley hulls and small fragments of a dark brown material. 

 On examining the feeding-places, hundreds of cocoons of tent cater- 

 pillars \31ala^osoiua] were found, individual fibres of the cocoon being 

 identical with those of the intestinal mass. A number of collected 

 cocoons on being given to a healthy animal were consumed with 

 avidity, the masticated pupae appearing in the intestinal contents 

 as dark brown fragments. 



The only treatment adopted was that of keeping the animals iiway 

 from the infested area until the pupae had emerged, the majority 

 recovering under this treatment.

According to Dr. E. T. Smith in charge of tick eradication in 

 Louisiana, the total number of cattledippingsin August was 2, 11 3.386 ; 

 84,461 horses and mules M^ere inspected and 32,188 were dipped. 



About 5,000 dipping tanks are available in Louisiana, in which 

 10,518,087 dippings took place under Federal supervision between 

 15th March 1918 and 1st September 1918, tick-infestation havijig 

 been thereby reduced to one-tenth of what it was at the beginning of 

 the work in April 1918.

On 1st July 1906, 728,565 square miles of territory, involving 

 15 States, were quarantined for Texas fever, the annual losses from 

 which were estimated at J:8,000.00<) at least. At this time the belief 

 prevailed generally throughout the South that the tick [Boophilus 

 (inrndnfi's] could not be exterminated, and though the work of eradica- 

 tion was begun in 1906 in a small way it progressed very slowly for 

 several years owing to limited funds and opposition to the movement. 

 Once it had been proved that extermination was possible, the work 

 progressed rapidly, and up to the present 52 per cent, of the original 

 quarantined area has been declared free. 



After the declaration of war, the work was pushed as a war measure, 

 there being 286 Bureau inspectors, 284 State inspectors, and 1,202 

 county inspectors in the field during the latter part of 1917, and 

 21,247 dipping vats were in operation. 



With the release of the entire State of Mississippi from quarantine 

 in December last, a wedge has been forced through to the Gulf of 

 Mexico, and as the force of inspectors will be increased as much as 

 possible during the coming season, it may safely be predicted that the 

 cattle tick will be completely exterminated in the South within tlie 

 next five years.
