disease, with figures of the American mildew (Sphacrothcca mors-uvae) 

 and the European mildew (Microsphaera Grossulariae), the former being 

 infinitely more deadly. There seems a danger of its spreading to curranbs 

 also. Of the various remedies proposed liver of sulphur appears to be 

 the most efficacious. The plants should be frequently sprayed with 

 a weak solution as a preventive. Where the fungus is already esta- 

 blished it is advisable to employ naphthol-/3. It is necessary to add soap 

 to dissolve this chemical in water. It can be mixed in a bucket and after- 

 wards diluted for use in the proportions of 1 kilo. (2 lb.) to 250-300 litres 

 (50-60 gallons) of water. — F. A. W.
