the iron wash may be used without the caustic soda, and with 

 the amount of paraffin reduced to 16 to 24 oz. to the 10 gallons ; 

 or if fungicidal properties are also required, copper, instead of 

 iron sulphate, should be used. With 24 oz. of solar distillate 

 the emulsion produced is of about the same density as water, 

 and will remain permanently suspended in it. With all these 

 washes, however, the tendency of the emulsion to rise to the 

 surface is so small, that no agitation is necessary during use. 



The report also contains an account of the investigations into 

 lead arsenate, as well as a description of the experimental 

 treatment of mussel scale, apple sucker, caterpillars, aphis, 

 apple mildew, woolly aphis and apple leaf -spot. The effect of 

 various washes on trees has been tested, and the nature of the 

 action of insecticides is discussed. 



OFFICIAL CIRCULARS AND NOTICES. 



The attention of the Board of Agriculture and Fisheries 

 has been called to the .danger which may arise to farm animals 

 in Great Britain in connection with the 

 Infection of Animals shipment, in foreign ports, of commodities 

 with Anthrax through which may contain the spores of anthrax, 



the Medium of Im- Anthrax is a disease which not only 

 ported Feeding Stuffs, affects all animals, especially cattle and 

 swine, but also human beings. Infection 

 is contracted by spores of the anthrax bacillus obtaining entrance 

 to the system through a cut or abrasion of the skin, and by 

 ingestion or inhalation of infected material. The disease may 

 be rapidly fatal. 



Anthrax is known to be extremely prevalent in animals in 

 many parts of the world from which supplies of raw hides, 

 horse hair and bristles, wool, and feeding stuffs, are drawn, 

 and there is ample evidence to show that infection is conveyed 

 to this country by means of these and other animal substances, 

 more especially when brought from eastern countries, where 

 the precautions taken to minimise the risk of the shipment of 

 infective material are in many cases quite inadequate, if indeed 

 they exist at all. Not only the cargo in question, but the parts 

 of the vessels in which it is carried may become the medium by 

 which infection is spread, unless adequate steps be taken to 

 guard against the risk.
