which will appear to the best advantage under the 

 conditions imposed by the problem in hand. The 

 necessary accent may accordingly be secured by 

 change in the scale, form, texture, color (leaf, 

 twig, or blossom) where mass planting is con- 

 cerned, and by more elusive qualities, such as in- 

 dividual leaf shapes and twig forms, where the 

 plant is isolated. In massed planting the accent 

 must be strong. If the prevailing lines of a 

 shrubbery mass are low and rounded, the intro- 

 duction of a Lombardy poplar or two will give 

 accent by change of scale and form as well. A 

 catalpa will give accent not only by the coarse 

 texture of its foliage, but by the large masses of 

 white blossoms in early summer and the still more 

 interesting pods in the autumn. Both the texture 

 and the color of the purple beech recommend its 

 use as an accent plant. On account of brilliant 

 autumn coloring, its distinguishing characteristic, 

 the tupelo-tree is often planted with hemlocks, to 

 make the most of their contrast. Many other ex- 

 amples might be given of similar planting prac-

A thorough knowledge of the plants at one's 

 disposal, and their characteristics, will be indis- 

 pensable in suggesting means of accent to the de-
