case, copious waterings during dry weather will be found beneficial. 

 In the treatment of vines, such plants as Glycine sinensis and Puer- 

 aria Thunhergiana can be layered the entire length of the previous 

 season's growth, thus giving a plant at every point. The period at 

 which the layer may be severed from the parent must be governed 

 by the quantity of roots made. Better to keep it on the plant than 

 to sever too early. After a season has elapsed the majority will 

 have rooted, if attention has been given; but it will not hurt to let 

 them stay for a longer period attached to the old plant. For furnish- 

 ing suitable wood for layers, old plants are sometimes cut down quite 

 close to the ground, in order to produce a quantity of young growth. 

 Plants so treated are termed "stools." Some of the plants which 

 layer easily are Rhododendron, Enkianthus, Gordonia, Magnolia, 

 especially the Asiatic species and their hybrid variations, Syringa, 

 Forsylhia, Ligustrum and the Hybrid Perpetual Roses.
