168 THE PRACTICAL PLANTER. 



suit ; that some kinds require more head- 

 room than others ; whether the surface be 

 flat or elevated ; and whether the situation 

 be exposed or sheltered, are all points of 

 particular consideration. 



But, if the plants are pruned and trained 

 from infancy, and according to the direc- 

 tions given in the last Section, the rule above 

 stated, of suffering no plant to whip another, 

 and keeping the extremities of the side 

 boughs just touching, will prevent a waste of 

 useful land. 



C 2d. GROUPED PLANTATIONS. And here, 

 two queries occur : Whether the plantation 

 be simply grouped ? or, Whether it be mixt 

 with nurses, with the intention of being after- 

 wards grouped ? 



In the first case, it should be kept rather 

 thick than otherwise, in youth ; that the trees 

 may, as it were, nurse one another. But, 

 from the time it hath arrived to the height 

 of from ten to twenty feet, according to soil 

 and situation, due attention should be paid 

 to regular thinning ; that the trees may not 

 be rendered unfit for any useful purpose for 

 which they may be ultimately intended.
