Many of its streets are cavern-like, for they run under the houses. . . . There is no regularity of style about them, and it is all one's life is worth to try to find the way among them without a guide and a torch.

"I'm going to take a much-needed nap—and it'll be all your life's worth to let me miss that train!"

"It's all one's life is worth to board one of these confounded cable-cars."

"[I]t's about all your life's worth to go out into that blizzard, even for just a few feet."

"I'm afraid you need to wait until the women say you can come in. It would be all your life's worth to go bustin in now."
