TREATISE ON THE CULTURE, &c. 109 



When you wish to increase them, encourage the finest 

 and cleanest shoots in summer, by trimming all the side 

 branches ofF thin ; and when you dress the shrubberies in win- 

 ter, lay down the strong shoots, which will take root, and be 

 ' lit to transplant in autumn following. When designed for use, 

 they should be trained up as standards and half standards, and 

 they will grow from six to twelve feet high. In summer, trim 

 off all the straggling and superfluous shoots so as that they 

 may make fine handsome heads. 



Barberries may also be raised from seed ; but suckers and 

 layers are best for preserving the sorts distinct.
