establishment of the mildew in fresh localities. Already the list of 

 affected areas has grown dangerously long, and the Agricultural Autho- 

 rities will incur a grave responsibility if they neglect to take prompt and 

 energetic measures to stamp out the disease. 



Other Governments, on the outbreak of this very disease in their 

 countries, have at once adopted legislative measures to stamp it cut. An 

 admirable instance of prompt action is supplied by the Swedish Agri- 

 cultural Authorities. In 1905 the disease was first discovered in Sweden 

 in one garden ; the same year legislative measures were put in force 

 temporarily forbidding the importation of foreign gooseberry-plants and 

 gooseberries, and enforcing the carrying out of strict preventive measures 

 against the disease.* In 1900 the disease was first discovered in 

 Europe in one garden in Ireland ; nothing has been done ; at the present 

 time (1906) the disease still flourishes in the same garden in which it 

 was discovered, and has now become widespread over a large part of 

 Ireland. 



How much longer will British fruit-growers be content that nothing 

 should be done to stop the increase of the disease ? At present the chief 

 danger to the English gooseberry-grower lies in the possibility of a further 

 importation of diseased gooseberry-plants, and in the continued spread of 

 the disease in Ireland, until by some means the fungus is conveyed to 

 England. I would suggest that some such body as the National Fruit 

 Growers' Federation should take the matter up, and not rest until the 

 Authorities are persuaded to give this country that legislative protection 

 against fungus diseases which other countries — and even our Colonies — 

 enjoy.
