1853. The best manner of its cultivation, however, 

 was not well understood, and the greater ease and 

 certainty with which the walnut can be grown has 

 led to the abandonment in recent years of many 

 of the almond orchards. 



Nevertheless the crop is one of considerable 

 importance, as the figures just given show. 



The total number of Persian or English walnut 

 trees in bearing in 1910 numbered 914,270, of 

 which all but about sixty thousand are in Cali- 

 fornia. The rapid increase of the industry, and its 

 prospect of still greater increase in the near future, 

 is shown in the fact that the number of young 

 trees, not yet of bearing age, was reported in 1910 

 as 806,413. 



The extension of the industry is shown also in 

 the fact that of the trees not yet in bearing no 

 fewer than 177,004 are in the single state of Ore- 

 gon, and 5,513 in Mississippi. These figures fore- 

 cast the spread of industry to meet the growing 

 demand for walnuts in America. 



The total production of Persian walnuts in 1909 

 was 22,026,524 pounds, with a valuation of 

 $2,297,336. 



It will thus be seen that the walnut takes rank 

 as a commercial crop of genuine importance. The

 of apricots, although not as yet approaching the
