The passages that you have scanned show that there are two kinds of rhythm. In one the accented syllable comes at the beginning of the foot, and in the other it comes at the end. The first kind is sometimes called falling rhythm and the second kind ruing rhythm. Scan illustrations of each kind again and see if the names are good ones.

Passages 1 and 2 show that the feet in rising rhythm are not all alike. In one kind the accented syllable is preceded by one unaccented syllable, and in the other it is preceded by two. Passage 1 is written entirely in the first kind of foot. In the second passage, the two kinds are combined.

Passages 3 and 4 show that there are two kinds of feet in falling rhythm also, - one in which the accented syllable is followed by one unaccented syllable, and another in which it is followed by two.
