In planted groups of several species, the fact (referred to on pages 25 and 73) must be kept in mind that the different species vary in regard to the amount of light which they require for normal development. Some, such as the Beech, Maple, and Holly, are very shade-enduring and at the same time they themselves make a dense shade; if associated with such light-needmg species as the Tulip tree, the Ash, Walnut, Cherry, and many others, the latter will be at a great disadvantage* the s

The pruner must study these relationships, must protect the weaker, and must give them at least a free upper crown, if he desires to keep the groups in harmonious development. A litde observation will soon show which trees are relatively weaker in their shade endurance. The most difficult task of the pruner, because requiring the most judgment, a sense of fitness, and a clear concep- tion of the results of his pruning, is that of training trees to desirable outline. This refers, of course, to single trees on the lawn, where the form and outline of the crown are the important features. The ^'natural," symmetrical form, typical of the particular species, is, to be sure, the ideal one to be attempted in general. But it is by no means certain that the individual tree will, if left alone, develop this form. Not only do conditions of the soil, which influ- ence the root development, find expression in the shape of the crown, leading to irregular and sometimes undesirable.
