When two walks separate from each other, it is always desirable to have them diverge in different directions, as at a [in fig. 74], rather than give the idea of reuniting, as at b. Where two walks join each other, it is generally better that they should meet at right angles, as at c, than to leave the sharp point, as in the acute angle at d. The most natural course for a road, or walk, is along the banks of a lake, or river; yet I have occasionally observed great beauty in the separation of these two lines; as where the water sweeps to the left, and the road to the right, or vice versa: the true effect of this circumstance I have often attempted to represent on paper, but it is one of the many instances in which the reality and the picture excite different sensations.
