Table XII. — Performance record of the Washington Navel orange tree No. 4-23-2, Pro- 

 ductive Washington strain, showing the number and weight of the fruits of each grade 

 and size produced, summarized for a period of six seasons, 1910 to 1915, inclusive. 



[This table plainly shows the tendency of this tree to bear heavier crops in alternate seasons. The weights 

 are given in pounds and ounces, except that the 6-year totals and the averages are expressed decimially 

 in pounds. This tree is listed in rank 50 in Table II and in rank 87 in Table IV.]
