THE POTATO FUNGUS. 



Mr. Moore of Glasnevin has sent me this morning a leaf of a po- 

 tato clothed with our old enemy Botrytis infestans, from potatoes in 

 the Royal Botanic Garden, Dublin. Everything seems to tend to a 

 repetition of the ravages of last year. I can persuade nobody here 

 that there are any fears, and all advice is vain. — M. J. B. (Garden- 

 ers' Chronicle.)
