CASCADE

The water was icy. She was about to swim to shore, when playfully, he leap over her. She sank underwater and opened her mouth to scream. She choked, and trying to rise to the surface, found him above her. She thought she had drowned; then found courage to propel herself the few feet to the shore. Then she felt the tremendous shower of his shaking beside her. (Bear, Chap. X, p. 50)
