without intervention of law. Perpetual sup- 

 plies of fruits and vegetables are now available 

 through the modern art of canning, through 

 cold storage, and by means of rapid transporta- 

 tion combined with cold storage in transit. Rapid 

 transportation and the perfection of the refrig- 

 erator car have made it possible to feed the 

 great consuming populations which have in re- 

 cent years come together in our great cities. The 

 gardens which supply our cities have been ex-

 gardener to beyond the limits of our own 

 domain. Rapid transportation and refrigera- 

 tion have made the Southern truck grower a
