 people, where the fole object of the perfons fo

 tion of the work. 



It is proper here to obferve, that in order to 

 fuccefsful planting, in grounds fuch as thofe we 

 are confidering, much more is neceflary to be at-

 a given time, to receive the plant. A difcrimina-

 Birch or a Spanifh Chefnut, an Oak or a Poplar, 

 will thrive beft on fuch and fuch a fpot. Even 

 after having afcertained thefe points, the nature of 

 the undertaking dill requires a little reflection. 



One queflion may be, Does the fituation of the
