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.
Strona 151 - n' all the kentry raoun'; It should be so built that it couldn' break daown: — "Fur," said the Deacon, "'t's mighty plain Thut the weakes' place mus' Stan' the strain; 'N' the way t' fix it, uz I maintain, Is only jest T' make that place uz strong uz the rest.
Strona 140 - Spanish sailors with bearded lips, And the beauty and mystery of the ships, And the magic of the sea. And the voice of that wayward song Is singing and saying still: 'A boy's will is the wind's will, And the thoughts of youth are long, long thoughts.

'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...
