Fig. 7 Planting beds should not be meaningless in outline 



for nursery stock, seeds and bulbs. Incidentally we acquired a host of 

 destructive insects and diseases which became very serious, in some 

 instances practically wiping out some of our most desirable native 

 species. 



Consequently a quarantine law was passed which barred most 

 of these plant importations, and aroused a storm of protest. Although 

 it seems probable that this embargo will be removed or modified in 

 time, it is possible that American horticulture will in the end benefit 

 from being forced to stand on its own feet, and revive the art of propa- 

 gation. The shortage of plant material resulting from the quarantine 

 is a considerable handicap to planting designers.
