be profitably fed to pigs in some instances, but it should first be boiled. 

 Burying should be deep if it is resorted to at all. Burning is to be 

 recommended. 



The application of chemicals to infested fruit has this disadvantage, 

 that the chemicals seldom penetrate far enough to kill all the mycelium, 

 and hence at a later date the uninjured mycelium may revive and again 

 produce spores, even after it has lain dormant all winter. 



From what I know of this fungus, I fully agree with all who have 

 attempted to suggest remedial measures in the direction of fungicides 

 applied to the fruit and foliage. There seems little hope that much 

 can be done in this manner if the weather is favourable to the disease. 

 The disease does comparatively little harm with us unless the weather 

 is very warm and moist, and it is in such weather that treatment with 

 fungicides is least successful. Everthing should be done that is 

 economically possible to keep down the number of the spores of the 

 disease, and of course it would be useless to deny that any treatment 

 of the trees that reduced the number of the spores when they were

few would be valuable if at a later date the weather conditions should 

 become more favourable. Among the treatments that may be recom- 

 mended on this score are various winter treatments, such as that with 

 lime, sulphur, and salt. As this winter treatment has a value for 

 many other purposes, its application to the present disease constitutes 

 for it a further recommendation. The same may be said with con- 

 siderable force with regard to all the different fungicides. If they are 

 being applied for any other disease they will have some effect also on 

 the Brown-rot. But too much weight must not be attached to these 

 statements with regard to the use of fungicides for this disease, for, 

 as before remarked, the disease is unlikely to do serious damage in 

 this State unless the weather conditions are favourable to it; and it 

 is precisely the weather conditions favourable to it that are most 

 unfavourable to the usefulness of fungicides. It seems absolutely
