the Scotch-fir leagues; from little knots of 

 which we often fee beautiful contrails arife. 

 When they are young, and luxuriant, efpeci- 

 ally if any number of them above four, or five, 

 are planted together, they generally form a 

 heavy murky fpot: but as they acquire age, 

 this heavinefs goes off, the inner branches 

 decay, the outward branches hang loofely, and 

 negligently; and the whole has often a good 

 effecl: ; unlefs they have been planted too 

 clofely. I am rather doubtful, how far deci- 

 duous trees mix well in a clump with ever- 

 greens : and yet we fometimes fee a natural 

 good effecl of light, and fhade, from the 

 darknefs of the fir contracting agreeably with 

 the fprightly green of a deciduous tree, juft 

 coming into leaf. In this however I am clear, 

 that if they are mixed, they ought not to be 

 planted, as they often are, alternately ; but 

 each kind together. 



Contrafls again arife from the mixture of 

 trees of unequal growth - from a young tree 

 united with an old one a flunted tree with a 

 luxuriant one and fometimes from two or 

 three trees, which in themfelves are ill-fhaped, 

 but when combined, are pleafing. Inequalities
