grown for canning purposes are sour red sorts, and are pro- 

 duced in New York, Michigan, Wisconsin, and California. 

 Maraschinos are sweet cherries, most of which are imported 

 from Italy and Spain. A Californian variety. Napoleon, is 

 also used to some extent for this purpose. Recent investiga- 

 tions point to the conclusion that a number of commercial 

 products may be obtained from cherry pits and cherry juice, 

 two by-products of the cherry industry. The fixed oil 

 expressed from the fresh kernels is much like almond oil, and 

 can be utilized in similar ways. Also, the volatile oil is quite 

 similar to bitter-almond oil, and can be used in the same way. 

 The pressed cake, that which remains after the oils are re- 

 moved, may be ground into a meal and used as a feeding 

 stuff. The waste cherry juice can be changed into syrup, 

 jelly and alcohol. 



APRICOTS 



Stems. — The common apricot varieties belong to the 

 species Prunus armeniaca. The trees are small, round- 

 topped, and resemble the peach tree. As in the plums, true 

 terminal buds are seldom formed. Lateral branch buds and 

 flower buds are found together in the axils of leaves (Fig. 

 169). Except for a few rudimentary leaves, the fruit buds 

 bear only flowers. Normally, there is but one flower (some- 

 times two) in a bud; they appear before the leaves. The 

 flower buds, which are lateral, occur singly at nodes; often 

 three buds are developed in the axil of a leaf, the central 

 one being a branch bud, while the two laterals are flower 

 buds. However, not all branch buds on a twig are accom- 

 panied by flower buds. The vigor of the tree and twigs, and 

 pruning methods will determine the position of the latter, to 

 some extent. In strong-growing twigs, the flower buds are 

 rather near the tip of a year's growth; on twigs of moderate
