Suggestions for Laboratory Worh. 125 



15. The almond is chiefly propagated by budding on 

 seedlings of the sweet or bitter, hard-shell almond (177). 

 The trees should be planted at least 24 feet apart, on light, 

 warm, well-drained soil (176, 178). 



16. The quality of almonds depends upon the smooth- 

 ness, symmetry and plumpness of the kernels. In regions 

 having a moist atmosphere, the nuts are bleached with 

 sulfur fumes to restore their brightness (179). 



17. The hazel has been little cultivated in North Amer- 

 ica, but the hardiness of the plant commends it for north- 

 ern localities where feAV fruits can be grown (181). 



18. The hazel may be readily propagated by cuttings 

 and thrives on nearly all soils (183). 



SUGGESTIONS FOR LABORATORY WORK 



1. Ascertain the species of nuts sold in your local mar- 

 ket, the price at which each is sold, and the locality whence 

 each came. 



2. Ascertain the species of nut trees that are native in 

 your locality. 



3. Require the students to study sample trees of the dif- 

 ferent kinds of nuts, so far as they are available, until each 

 can name every one at a glance. 



4. Practice grafting the different nut trees, so far as 

 practicable. 



5. Study the variations of the wild nuts produced in 

 your locality, and require each student to select his ideal 

 type, giving reasons for his choice.
