moist, sour state by it. But the stones or 

 gravel prepared as directed, allow any undue 

 portion of moisture to filter away, whilst at 

 the same time, they prevent the roots of the 

 trees from penetrating the injurious substra- 

 tum equally as w r ell as in the case alluded 

 to. 



The border ought always to be made three 

 months at least before the time of planting 

 the trees in it, so that it may not settle much 

 afterwards. Although this method of form- 

 ing the border may be considered troublesome 

 and expensive, yet attention to the method 

 laid down, is of the utmost importance to the 

 fertility of the trees. And the expense thus 

 incurred is not near so great as what it would 

 be afterwards, in endeavouring to render the 

 trees healthy and productive, when such at- 

 tention had not been paid at the first form- 

 ation of the border.
