DESCRIPTION OF PLATE XII. 



Experiments at Biggs, Cal. (Sulphur ami lime.)' Looking west between rows 9 

 and 10, May 14, 1895. Both rows were sprayed before blooming. Row 9 was treated 

 witli 10 poimds sulphur, 20 pounds lime, and 45 gallons of water, and row 10 with 

 10 pounds sulphur, 8 pounds lime, and 45 gallons of water. Row 8, adjoining row 9 

 at the south, and row 11, adjoining row 10 at the north, were mitreated. The aver- 

 age value of fruit matured per tree on row 9 was $3.35, and on row 8 only 91 cents. 

 The average value of fruit matured per tree on row 10 was $3.90, and on row 11, $1.35. 

 As determined by the comparative value of the peaches set by the trees, the spray 

 used on row 9 showed a net gain over row 8 of 457 per cent, and that used on row 

 10 showed a net gain over row 11 of 337 per cent (p. 117) . It may be seen that the 

 lower limbs are not as thickly covered with foliage where the sulphur sprays are 

 used as where the copper sprays are used. This is especially true wherti the former 

 is applied too late or too strong. (See PI. XL)
