disease, it reduces somewhat the ornamental value of these 

 shrubs in that it causes white patches upon the leaves and 

 young shoots. The older leaves are not usually attacked 

 and on those which are affected the spots generally disappear 

 with age. 



If troublesome, dry "flowers of sulfur" should be well dusted 

 over the affected parts. This should be done on a still day, 

 preferably during sunshine. The treatment should be repeated 

 about every ten days until the fungus disappears. 



THE LEADING BROAD-LEAVED EVERGREENS AND 

 THEIR ADAPTATION.— Dunbar 



Broad-leaved evergreens do not form an important or con- 

 spicuous feature in landscape-gardening throughout the north- 

 eastern or New England States. For broad distinctive effects 

 coniferous evergreens must be depended on. Many broad- 

 leaved evergreens that succeed very well in the Carolinas and 

 adjacent States cannot be relied on in New England. Cold, 

 searing, penetrating winds are very trying to most broad- 

 leaved evergreens, and brown and scorch the foliage. The 

 limited number suggested in the following notes mostly require 

 to be more or less protected by the lay of the land or otherwise. 



Amongst broad-leaved evergreens, rhododendrons unques- 

 tionably take the first place wherever conditions are at all 

 propitious for their cultivation. General experience shows that 

 rhododendrons will not thrive in soil that contains lime. If 

 the soil indicates a specific alkalinity of three, and the subsoil 

 is porous and naturally well drained, it is perfectly safe to 

 remove the soil to a depth of two and one-half to three feet 

 and replace with humus or peat enriched with cow-manure on 

 the surface. This is exactly what has been done in the rhodo- 

 dendron valley in Highland Park, and it has been under ob-
