of fruits produced instead of on the weight of the fruits. This serves 
to emphasize the small-sized fruits and the Cull grades. 
Figure 6, like figures 4 and 5, shows the average number of fruits 
produced by the 10 highest and 10 lowest yielding trees, but the yields 
of fruit of the different sizes are expressed as percentages of a packed 
box. The highest producing trees bore an annual average of 2.15 
packed boxes per tree, as compared with a yield of 0.63 of a packed 
box from the lowest yielding trees. This difference indicates some- 
thing of the value and desirability of growing only trees of the best 
strain in commercial orchards. These yields are very low, especially 
those from the best trees, but it should be remembered in this con-

Fig. 4.— Diagram showing the variations in the commercial sizes and grades of fruit on the 10 heaviest 
producing trees in comparison with the 10 lowest producing trees in the experimental performance-record 
plat of Valencia oranges. The percentages are based on the weight of the average crop per tree for a 
4-year period. Figure 5 shows similar variations based on the number of fruits produced. 
nection that several of the conditions which were considered essential 
for the location of the performance-record plats were prohibitive to 
Lhe production of large crops. It is also interesting and important, 
especially from the standpoint of dollars and cents, to note that the 
highest producing trees bore 33 per cent of their crop in the most 
desirable and valuable sizes, while the low-yielding trees had only 18.7 
per cent of their crop in these sizes. Figuring the productions here 
shown on the acre basis at the rate of planting in the performance- 
record plat, it is found that the high producing trees bore 172 packed 
boxes as compared with 50.4 packed boxes per acre from the lowest 
producing trees. The values, delivered at the packing house, of
