and wind force. This excessive growth and consequent weakness of 

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

 of the indifference in degree of forcing conditions, but everywhere 

 the apricot needs watchfulness and timely aid in building up its 

 strength. Space forbids us going into details in regard to pruning 

 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: 



Royal: — A French variety- and at present the leading apricot in 

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

 flavor; good bearer and ripens evenh*. A favorite with the canners 

 and an excellent variety for drying. Fruit roundish, large, oval, 

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

 orange, firm and juicy with a rich vinous flavor. 



Blenheim: — A very good variety, above medium, oval; orange 

 with deep \-ello\v, juicy an:l tolerably rich flesh; vigorous grower 

 and regular, prolific bearer. Fruit a little larger and ripens a little 

 later than the Royal. 



Early Golden: — Small roundish oval with suture well marked 

 and extending half way around; skin smooth, pale orange, flesh 

 yellow, with very good flavor, free stone; ripens before Royal.
