The rose is liable to attack from various insect enemies. The rose slug so destructive during the Summer is effectually destroyed by dusting the plants with powdered white Hellebore and lime, or dissolve a tablespoonful of the Hellebore in two gallons of hot water and apply when cold with the syringe. For red spiders keep the foliage well syringed, being careful to wet the under side of the leaf. Mildew may be remedied by giving the plants a good dusting of sulphur, and for that great pest of the window garden, green fly, nothing is better than tobacco smoke or strong tobacco water.
