ON THE CULTIVATION OF TREES. 325 



The orange and citron we derive from Japan ; the 

 pomegranate from Africa. 



New Holland, which contains not less than three or 

 four thousand different plants, has but three or four spe- 

 cies of fleshy fruit-trees, and the fruit of these is small 

 and insipid. 



In some fruits we distinguish those in which the fleshy 

 part is attached to the nut or kernel, as the plum and the 

 peach, and those which are separated from it, as the 

 apricot. Peaches, plums, apples, and pears, are of the 

 family of Rosacece. 



Caroline. This family is, then, equally celebrated for 

 the beauty of its flowers and the excellence of its fruits. 



Mrs. B. There are two species of peach, both of 

 which we derive from Persia : one of them, having a 

 smooth skin, we distinguish by the name of Nectarine. 

 Each of these species has two varieties, in one of which 

 the pulp adheres to the stone, in the other it is separate 

 from it. 



The other members of this family are the almond, the 

 apricot which comes from Armenia, and the cherry, of 

 which there are five species. There are besides, of this 

 family, the plum, the strawberry, the rose, the service- 

 tree, and the medlar. 



The orange forms a family of its own, bearing its name 

 Jlurantiaceae, and includes the lemon, the citron, and the 

 pample, or mousse. 



The sweet orange and the bitter were formerly suppos- 

 ed to be of the same species, and the sweet was often 

 grafted on the bitter orange ; but this is an error : they 

 are of different species, and the sweet orange does not 

 require grafting. 



There are no less than twelve known species of wal- 

 nut-trees ; one of which we derive from Syria, and the 

 eleven others from America. We cultivate the first for 

 its fruit, but the latter produce the finest timber.
