have become an article of extensive trade, particularly so in Upper 

 India. In 1887 there were 175,500 cases of Apricots sent from 

 California, also 3 million pounds of the evaporated fruit [" Journal 

 Society of Arts"]. Dried Apricots are extensively exported from 

 Mildura (Victoria) to the London market, as well as to different parts 

 of Australia. Apricots, Peaches, Plums and Cherries can additionally 

 be preserved as syrupid fruit by heating for a | or \ an hour in a 

 water-bath the fresh fruit, placed with sugar in glass bottles, by 

 strewing on the surface of the contents salicylic acid in the proportion 

 of a teaspoonful to 4 Ibs., and by finally closing the vessels with 

 salicylic paper. The Black Scale of Olive-trees, Lecanium Oleae. 

 extends also to the Apricot-tree and to many other kinds of orchard 

 trees. Against the so-called Shot-hole fungus Mr. C. French re- 

 commends spraying with strong Bordeaux-mixture directly after 

 pruning, with a weaker solution after the leaves appear. Many kinds 

 of insects, attacking orchard-fruits, can be much subdued by placing 

 loose grass around the trees, and burning it, while the insects largely 

 harbor under it at day-dawn. Where water-pressure is available, 

 insects can be destroyed by the mechanic force of spray, with 

 avoidance of dangerous admixtures. 



Prunus Capuli, Cavanilles. 



Mexico. The fruits are locally sold in the markets under the name 

 of Capulirios. 



Prunus Caroliniana, Aiton. 



South-Eastern States of North-America. Porcher regards it as 

 one of the most beautiful and manageable evergreens of the States. 

 It can be cut into any shape, and is much employed for quick and 

 dense hedges. It can be grown on coast-land. 



Prunus cerasifera, Ehrhart. (P. Myrobalanus, Desfontaines. ) 



The Cherry -Plum tree. Countries at and near the Caspian Sea. Of 

 rather tall growth. The fruits called also Mirabelles (which name is 

 given to some varieties of P. domestica as well), whence long ago 

 the objectionable designation Myrobalane-Cherry-Plum arose. Among 

 all kindred species it is this one which flowers earliest, indeed before 

 the development of its leaves, hence its claims for decorative horti- 

 culture. Splendid for hedges ; grows vigorously in the poorest soil ; 

 ramification impenetrably dense ; bears almost any extent of clipping ; 

 not hurt by exposure to sea-air [Daniels]. The fruit-yield is some- 

 times astonishingly large. On this and some other cultivated species, 

 see also "Koch's Dendrologie," 1869. 



Prunus Cerasus, Linn4.* 



The Cherry-tree. Orient, especially in the countries near the 

 Caspian Sea. The name applies strictly only to the species, dis- 

 tinguished by never assuming large dimensions, by emitting suckers,
