Pirtjs, Linn. From peren, the Celtic word for 

 •pear. Linn. 12, Or. 2, Nat. Or. Pomacece. 

 To this genus belong tlie Pear and Apple, as 

 well as the Service-tree, aud many others, 

 either prized for their fruit or their orna- 

 mental appearance. In our shrubberies, they 

 grow in auy common soil ; but for the more 

 highly cultivated ones a deep loam is neces- 

 sary. They are increased by seeds, and the 

 established kinds are multiplied by grafting 

 the choicer on the common kinds. Syno- * '
