§ 14. It may be well also to note, for the advantage of the general student of design, that, in foliage and bough drawing, all the final grace and general utility of the study depend on its being well foreshortened; and that, till the power of doing so quite accurately is obtained, no landscape-drawing is of the least value; nor can the character of any tree be known at all until not only its branches, but its minutest extremities, have been drawn in the severest foreshortening, with little accompanying plans of the arrangements of the leaves or buds, or thorns, on the stem. Thus Fig. 65 is the extremity of a single shoot of spruce foreshortened, showing the resilience of its swords from beneath, and Fig. 66 is a little ground-plan, showing the position of the three lowest triple groups of thorn on a shoot of gooseberry.[8] The fir shoot is carelessly drawn; but it is not worth while to do it better, unless I engraved it on steel, so as to show the fine relations of shade. § 15. III. FELLOWSHIP.--The compactness of mass presented by this little sheaf of pine-swords may lead us to the consideration of the last character I have to note of boughs; namely, the mode of their association in masses. It follows, of course, from all the laws of growth we have ascertained, that the terminal outline of any tree or branch must be a simple one, containing within it, at a given height or level, the series of leaves of the year; only we have not yet noticed the kind of form which results, in each branch, from the part it has to take in forming the mass of the tree. The systems of branching are indeed infinite, and could not be exemplified by any number of types; but here are two common types, in section, which will enough explain what I mean. [Illustration: FIG. 67.] § 16. If a tree branches with a concave tendency, it is apt to carry its boughs to the outer curve of limitation, as at A, Fig. 67, and if with a convex tendency, as at B. In either case the vertical section, or profile, of a bough will give a triangular mass, terminated by curves, and elongated at one extremity. These triangular masses you may see at a glance, prevailing in the branch system of any tree in winter. They may, of course, be mathematically reduced to the four types _a_, _b_, _c_, and _d_, Fig. 67, but are capable of endless variety of expression in action, and in the adjustment of their weights to the bearing stem. § 17. To conclude, then, we find that the beauty of these buildings of the leaves consists, from the first step of it to the last, in its showing their perfect fellowship; and a single aim uniting them under circumstances of various distress, trial, and pleasure. Without the fellowship, no beauty; without the steady purpose, no beauty; without trouble, and death, no beauty; without individual pleasure, freedom, and caprice, so far as may be consistent with the universal good, no beauty.
