and wind force. This excessive growth and consec|uent weakness of 

 the apricot is greater in sorne parts of the state than others because 

 of the indifference in degree of forcing conditions, but everywhere

 this valuable tree. But we advise any one who seeks a knowledge 

 of the business to purchase a copy of 'California Fruits', as it is a 

 thorough treatise on this desirable fruit. We herewith give descrip- 

 tions of a few choice varieties: 



R()V.\u:— A French variety and at present the leading apricot in 

 California; of large size, if well thinned, free stone, fine color and 

 flavor; goo:l bearer and ripens evenly. A favorite with the canners 

 and an e.KeelienL variety for drying. Fruit roundish, large, oval, 

 slightly compressed; skin dull yellow with ornnge check, flesh pale 

 orange, firm and juicy with a rich vinous flavor.
