Examples

“Miles on miles of quagmire, varied only by bright green strips of comparatively solid ground, and by deep and sullen pools fringed with tall rushes, in which the bitterns boomed and the frogs croaked incessantly: miles on miles of it without a break, unless the fever fog can be called a break.”
