Prevention of Anthrax. The Home Office Order No. 1293, 

 dated Dec. I2th, 1905, on this subject, is made under 

 Section 79 of the Factory and Workshop Act, 1901. It 

 provides for the prevention of dust from wool or hair by 

 ordering the opening and sorting to be done only (i) after 

 steeping in water ; or (2) over an efficient opening screen, 

 with mechanical exhaust draught, in a room set apart for 

 the purpose and in which no other work than opening is 

 carried on. Mohair, other than Van mohair, only needs 

 to be sorted over a down draught. Van mohair, Persian 

 locks, and Persian, must all be steeped before being 

 opened. Alpaca, pelitan, East Indian cashmere, Russian 

 camelhair, Pekin camelhair and Persian [or so-called Per- 

 sian, if to be sorted or willowed] must be steeped before 

 opening, or opened over efficient opening screen. It also 

 provides for the use of overalls and respirators, cubic 

 space per person (1000 c. ft.), temperature of room (not 

 lower than 50 F.). Treatment of cuts and sores, washing 

 of hands, burning of dust and other refuse, rules for treat- 

 ment of damaged hair, proper kind of screen and board, 

 lime-washing of rooms yearly, daily disinfection of floors 

 and sweeping thereafter, etc., etc. 



Anthrax orders are issued by the Board of Agriculture 

 under the Diseases of Animals Act, 1894, and provide for 

 the precautions to be used in treatment of a sick animal, 

 and (i) the burial at a depth of not less than 6 ft., with i ft. 

 of lime beneath and above the carcase of an animal dead 

 of anthrax, or (2) the destruction of a dead animal by 

 heat or chemical agents. The local authority must carry 

 out the provisions of the order in these and other 

 particulars.
