had been obtained from the same nursery. Practically, not a single berry 

 remained free from the disease. The disease is now known from nine 

 localities in Denmark. 



Sweden and Norway. — The disease has been discovered in two localities, 

 Karlshamn (Sandvik) and Falsterbo, in Sweden, and in one locality 

 (Langesund) in West Norway. The disease had been introduced with 

 gooseberry plants imported from a nursery at Korsor, Denmark, in 1900. 

 Prompt and energetic legislative measures to combat the disease have at 

 once been taken by the Swedish Government. 



Finland. — The disease was first discovered in a few localities in 1901 ; 

 it has since been found to be somewhat widely distributed through 

 Finland. The fungus was introduced on diseased gooseberry bushes 

 imported from Eussia. The Government have now adopted the same 

 legislative measures as those employed in Sweden — viz. the temporary 

 prohibition of the importation of gooseberry bushes and gooseberries, the 

 inspection of nurseries, with control over plants supplied from them, and 

 the destruction (with compensation), or spraying, of affected stock. 



Austria. — Professor Aderhold has recently reported the occurrence of 

 the disease at Pinzgau (Salzburg). 



II. — The Need foe Legislation. 



In October 1905 I published in the "Gardeners' Chronicle" an 

 article u On the Present Danger threatening Gooseberry-growers in 

 England." I wrote as follows : " I would point out that gooseberry growers 

 in England may best realise the danger threatening them by visiting a 

 hop-garden overrun by the hop-mildew, or a rose-garden where there is 

 an epidemic of mildew. The American gooseberry-mildew is a species * 

 very closely related to the hop- and rose-mildews, and would nourish no 

 less vigorously than do these in the English climate. Where it has 

 occurred in Ireland, it has often caused the wholesale destruction of the 

 gooseberry crop. It is not too much to say that if once it is allowed to 

 gain a foothold in the gooseberry-growing districts of England it will 

 never be completely expelled. 



M So long as the disease is allowed to nourish in Ireland, it menaces the 

 English grower. English gooseberry-growers should demand from the 

 Authorities the prohibition of uncontrolled importation of gooseberries 

 into England or Ireland, and they should demand further that every 

 means be taken to stamp out the disease in Ireland. It has already been 

 ascertained that the mildew has been introduced into Ireland by diseased 

 stock imported into nurseries from America ; further action in the matter 

 lies beyond the power of the individual, and must be undertaken by the 

 Government, possibly with international assistance. Eesolutions (on the 

 subject of systematic international work for the combating of plant- 

 diseases) have already been passed by the Vegetable Pathological Section 

 at the International Agricultural Congresses, and these should form the 

 basis for international procedure. 



* I have given a full description of the fungus (with figures), together with an 

 account of its method.- of attack and the preventive measures to be taken, in 

 vol. xxv. of the E.H.S. Journal, and in succeeding volumes.
