The note which we recently gave detailing the work of the landscape gardener of Fairmount Park in destroying root fungus on shrubs and trees by the use of sulphur has had a wide circulation since it appeared in our paper. It appears that similar attention is being given to these dangerous fungous parasites in the Old World, and sulphur is used also as a remedy. The chestnut trees in the neighborhood of Nantes, France, have suffered severely, many being wholly destroyed. By laying bare the roots, and sprinkling with sulphur before refilling the earth, the trouble has been arrested.
