THE ORANGE IN CALIFORNIA — VARIETIES. 71 



disease much attention has been given to its culture for stocks. 

 While the sweet orange requires good soil and high, dry eleva- 

 tion, the sour orange seems best adapted to low, wet soils, such 

 as it is grown in in Florida, known as "hammocks," and along 

 the margins of swamps. But those kinds of land do not 

 exist in our State, and while the sour orange stock is hardy 

 beyond question and thrives in our dry soils under entirely 

 different conditions, it has not superseded the sweet orange 

 stock or Tahiti Seedling, as was predicted it would, and perhaps 

 never will. Trees grown on sour stocks of the same age in 

 almost every section of the State show a marked difference of 

 growth. The trunks are not as large as those on sweet stocks, 

 and show less expansion of root system. The influence of the 

 stocks on the bud is also traceable. Those on sweet root show 

 a darker foliage, with a tendency to improvement in the 

 quality of the fruit. The tree becomes of extraordinary large 

 size, and the product twice or more as large. The susceptibility 

 of the sweet stock to the gum disease is obviated by the care 

 bestowed upon it, which is now practiced and thoroughly 

 understood.
