only greater, but of a superior quality. The bushes are 

 pruned much in the manner I have described ; and I 

 have observed that they seldom exceed six feet, and a 

 great many are not more than five ; their branches are 

 wide apart, and the middle of the bushes extremely open. 

 There are some, probably, who may object to the 

 trouble, or who may find it inconvenient to prune their 

 Nut trees in the regular way : should this be the case, 

 something still may be done to prevent their running 

 into a wild state. They may be looked over, for the 

 first two or three years, till their heads have been formed 

 with some degree of regularity, and they may then be 

 suffered to grow at length ; but, even then, it can take 

 up but little time, and, consequently, cause but little 

 expense, in having them looked over once a year, during 

 the winter, to clear away the suckers from the roots, and 

 to thin out the heads where the branches are crowding 

 or galling each other ; remembering that, where the 

 heads are crowded with wood, the crop is always defec- 

 tive, except near the extremities ; and where they are 

 kept thin, it is abundant.

As many of the French and Flemish Pears succeed 

 well when grafted upon the quince stock, all such as 

 have been ascertained to possess this property will be 

 noticed at the end of the descriptions.
