In the level garden a spring is often created to issue from among moss-covered rocks to form the origin of a stream, which has been devised to wind through the garden from the east towards the south and then pass out to the west. However, the direction should be determined according to the character of the ground, so as to furnish a beautiful line and to aid the drainage as well. Needless to say that the stream should not be straight, but a caution is necessary against too many and unnatural curves. The glade should be steep at the beginning and less so towards the end. Generally it should not flow through the centre, cutting the garden into two. When it is to convey the idea of a big river, it looks natural to use a group of big rocks at the bend for the water to dash against. Sometimes tiny snake baskets with stones held in position with posts are quite appropriate. But for streams flowing through the ground with only a little glade, no stones should be used and at the bends only the posts instead of stones should be driven in to preserve the bank.
