Oleas, Olive, about twelve species and varieties. 0. Eu- 

 ropcea longifblia is the species that is cultivated to such an 

 extent in the south of France, and Italy. 0. Europcea 

 latifblia is chiefly cultivated in Spain. The fruit is larger 

 than that of Italy, but the oil is not so pleasant, which is 

 obtained by crushing the fruit to a paste, and pressing it 

 through a woollen bag, adding hot water as long'as any oil is 

 yielded. The oil is then skimmed off the water, and put into 

 barrels, bottles, &c., for use. The tree seldom exceeds thirty 

 feet, and is a branchy, glaucous evergreen, and is said to be 

 of great longevity. Some plantations at Turin, in Italy, art/ 

 supposed to have existed from the time of Pliny. It fre-

 flowers white, in small racemose axillary spikes. 0. capensis 

 has thick, large, oblong foliage; flowers white in large tcr-
