Everyone is familiar nowadays with the so- 

 called Navel Orange, which combines the very 

 notable quality of seedlessness with large size and 

 general excellence of quality. 



The seedless condition of this orange is not the 

 result of skillful selection, but appeared as a 

 "sport" in certain wild oranges of Brazil. There 

 are almost numberless varieties of oranges grow-

 was traveling through South America, was sur-
