covered with dark pines and waving birch, which cast a solemn gloom over the 
lake below, a few mountain ashes, joining in a clump, and mixing with them, 
have a fine effect. In summer, the light-green tint of their foliage, and, in 
autumn, the glowing berries which hang clustering upon them, contrast beauti- 
fully with the deeper green of the pines ; and, if they are happily blended, and not 
in too large a proportion, they add some of the most picturesque furniture with 
which the sides of those rugged mountains are invested." One great advantage 
of the mountain ash, in all situations, is, that it never requires pruning, and never 
grows out of shape.
