In planting trees in groups, our gardeners generally balance three against one, one against two, five against two, etc. They are so distributed that all of them may be seen from different angles. Certain trees by the pond should not be allowed to grow too high or they will inconvenience the enjoyment of the moon. The planting should not be too thick to obstruct the passage of the wind and to obscure the contour of the ground, or too sparing to lose continuity. Every tree, or group of trees, should be beautiful by itself and contribute its part to the beauteous harmony of the whole. By balancing one group against another, poising one space against another, uniting straight lines with curvatures, following the rhythm created by the masses, spaces, and lines to a climax, the central point in the garden, the laws of Nature are fulfilled by showing unity and harmony and the relation of one towards another.
