pouring this into 45 gallons of water. Either of these two remedies 

 is to be applied by a proper spraying pump Nixon's being one of the 

 best ; both can be cheaply prepared. Mr. Galloway has at one time 

 thus treated successfully 400,000 young trees. The ammonial solu- 

 tion is the least expensive of the two and more easily prepared and 

 applied. 



Prunus ilicifolia, Nuttall. 



California. In deep rich soil, valuable for evergreen hedges of 

 intricate growth. Fruit about \ inch diameter, red or black, of a 

 pleasant sub-acid flavor, but somewhat astringent [Gibbons]. 



Prunus insititia, 



The Bullace. Middle and Southern Europe, North-Africa, 

 Western Asia to the Himalayan mountains. Professor Heer has 

 proved, that the lacustrine Swiss of the stone-age were already 

 acquainted with the Bullace as well as the Sloe. This species yields 

 some of the Damascene-Plums. P. cerasifera seems descended from 

 P. insititia, and this again may be the original wild plant of P. 

 domestica [London, J. Hooker]. P. Brutia (Terraciano) is a closely 

 allied mountain-plant from Calabria. 



Prunus Japonica, Thunberg. 



The Wild Plum of Japan. A small, ornamental tree, cultivated 

 for its often double flowers. The fruit edible. 



Prunus Lauro-Cerasus, Linne. 



The Cherry-Laurel. Persia and adjoining countries. A tall shrub 

 or small tree, with evergreen remarkably shining foliage ; the latter, 

 as not quickly shrivelling, valuable for garlands and for other decora- 

 tive purposes. Bears still fruit at 60 23' in West-Europe. From the 

 leaves the medicinal laurel-water is distilled. An infusion of the 

 leaves is very effective in destroying all kinds of insect-parasites on 

 garden-plants, also recommended for mixing with whiting to kill flies 

 in buildings. 



Prunus Lusitanica, Linn. 



The Portugal Cherry-Laurel. A small tree, seldom over 30 feet 

 high, not of strictly industrial value, but mentioned here as one of the 

 very hardiest among evergreen trees not coniferous. Indigenous also 

 in Spain and perhaps the Canary Islands. 



Prunus Mahaleb, Linn4. 



South-Europe and South- Western Asia. It deserves some atten- 

 tion on account of its scented seeds and also odorous wood, the latter 

 used in turnery for pipes and other articles. The flowers are in use 

 for perfumes. The tree is hardy in Norway to lat. 63 26'. The 

 kernels are used for making marasquino-liqueur [Prof. Wittstein].
