readily mastered by anyone who has grasped the 

 fundamental ideas of plant development through 

 hybridization and selection. A few words must be 

 added, however, about the shrubs and vines that 

 break up the long stretches and furnish an essen- 

 tial border or background of foliage on the walls 

 or trellises or pergolas about your lawn. No door- 

 yard is quite complete without such a background. 



Needless to say, Mr. Burbank has not over- 

 looked this esthetic requirement. n Among the 

 shrubs and small trees of more familiar type with 

 which he has worked extensively in producing ma- 

 terials for hedge or lawn decoration are the black 

 alder, the barberry, the flowering dogwood, the 

 sumac, the elder, the hazelnut, the mulberry, the 

 osage orange, the laurel, the rhododendron, the 

 witchhazel, the wild plum, and the abutilon or 

 flowering maple from Chile. ^ } 



All these have attractive qualities of foliage, 

 and a good many of them have added attractive- 

 ness because of their beautiful flowers or their 

 edible fruits. Almost all of them give oppor- 

 tunity for experiments in development by cross- 

 breeding and selection, that add to their attrac- 

 tiveness from the present standpoint. If you have 

 none of them on your grounds, it will be well to 

 secure a few for transplantation this autumn, to 

 be ready for hybridizing experiments next season. 



With the ornamental vines, Mr. Burbank has 

 worked no less extensively, and he has developed 

 these in sufficient variety and profusion to meet 

 every need. The ivies, for example, have been
