Strona 151 - At half past nine by the meet'n'-house clock,— Just the hour of the Earthquake shock! —What do you think the parson found, When he got up and stared around? The poor old chaise in a heap or mound, As if it had been to the mill and ground! You see, of course, if you're not a dunce, How it went to pieces all at once,— All at once, and nothing first,— Just as bubbles do when they burst.

'Fore they think on't guess they'l sprout (Like a peach thet's got the yellers), With the meanness bustin' out.

Strona 145 - When Cuba's weeds have quite forgot The power of suction to resist, And claret-bottles harbor not Such dimples as would hold your fist, — When publishers no longer steal, And pay for what they stole before, — When the first locomotive's wheel Rolls through the Hoosac tunnel's bore ; — Till then let Gumming blaze away, And Miller's saints blow up the globe ; But when you see that blessed day, Then order your ascension robe...
