inches in length, of a branch, including both fruit buds and 

 branch buds. Describe the arrangement of the buds. What color 

 is the young wood ? 



4. Spanish race. The Spanish race {Amygdalu* persica) in- 

 cludes the following varieties : Cobler, Columbia, Victoria, Texas, 

 Sanders, and several others. The trees are very large ; the limbs 

 large, long, and spreading ; the branches low ; the flowers usually 

 large ; the foliage small and flat. The fruit is very decided in 

 character, very late, and nearly always yellow. This race is 

 adapted to isothermal lines north of those in which the South 

 China race flourishes. 



Secure branches from one or more varieties of this race. 

 Study carefully, and compare with the races already studied. 

 Make a drawing, natural-size, and four inches in length, of a 

 branch, showing the position and arrangement of the buds. 

 Describe any differences in this respect between this race and 

 the others studied. What is the color of the bark ? Where do 

 you find the fruit buds ? 



5. Peen-to race (Amygdalus platycarpa). The Angel and the 

 Waldo are two varieties which are seedlings of the Peen-to. 

 This is probably the least important race, and the varieties are 

 restricted as to the location in which they will grow. The trees 

 are rather large and vigorous, with willowlike branches and 

 large flowers. 



Secure branches from one-year-old and two-year-old wood of 

 the above varieties. Make a drawing, natural size, and four 

 inches in length, of a branch, showing both leaf and branch buds. 

 Describe fully. Compare this race with the South China race, 

 and describe any difference. 



Comparative study of the peach. Describe in detail the differ- 

 ences between the races in the twigs, in the leaf and flower 

 buds, in the color of the branches, in the position and arrange- 

 ment of the buds, etc. as seen by your study.
