or very nearly touch each other, very little digging or hoeing is necessary ; 

 provided care be taken to grow one set of trees and shrubs as undergrowths, 

 which shall cover the soil and keep down all weeds, and another set of trees 

 allowed to attain their full growth, which should be those that are to remain as 

 standards. For want of adopting some system of this kind in the management 

 of shrubberies and young plantations, they not only become an annual expense, 

 but that expense is employed in rendering them unsightly ; for what can be 

 worse than to see ground hoed and raked among haggard-looking shrubs and 

 naked-stemmed trees, which seem to be incapable of deriving any benefit from 

 culture. The practice of endeavouring to grow flowers and flowering shrubs 

 on the margins of shrubberies should seldom be continued more than two or 

 three years after the shrubbery is planted ; because they cannot thrive, and 

 their sickly etiolated appearance is any thing but ornamental. In short, as we 

 have often before stated, flowering shrubs and flowers never thrive among 

 ordinary shrubs and trees, and therefore ought not to be planted among them. 

 Thickening Strips and Belts ivhick have never been thinned. — The quickest 

 way of doing this is to cut down a number of those trees that stole ; but the 

 most effective mode, if the plantation contains pines or firs which have not 

 lost their lower branches, is to cut them down to within 6 or 8 feet of the 

 ground, leaving the whole of the strength of the roots to be thrown into the 

 remaining side branches. The Scotch pine and the spruce fir treated in this 

 way form admirable low growths, and very soon render a narrow strip quite 

 impenetrable by the light. We have recently seen this in various instances, both 

 in the north, and in Surrey. Where there are no branches on pines and firs 

 nearer the ground than 10 or 12 feet, the trees might be cut down at such a height 

 as to leave two tiers of live branches, and the whole or a part of these might 

 be tied down to the remaining part of the trunk, by which they would first 

 descend to the ground and spread along the surface, and afterwards the ex- 

 tremities of the shoots would grow up from it so as to form a dense evergreen 

 mass. Of all the faults in the management of plantations, with which the 

 country abounds, there is none so common as that of leaving narrow strips of 

 plantation unthinned, by which the very intention of these plantations is most 

 effectually defeated.
