Strona 148 - So the Deacon inquired of the village folk Where he could find the strongest oak, That couldn't be split nor bent nor broke, — That was for spokes and floor and sills; He sent for lancewood to make the thills; The crossbars were ash, from the straightest trees, The panels of white-wood, that cuts like cheese, But lasts like iron for things like these; The hubs of logs from the "Settler's Ellum...
Strona 138 - 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.

From the strong principle of inheritance, any selected variety will tend to propagate its new and modified form.

Strona 144 - Ef you're arter folks o' gumption, You've a darned long row to hoe. Take them editors thet's crowin' Like a cockerel three months old, — Don't ketch any on 'em goin', Though they be so blasted bold; Aint they a prime lot o' fellers? 'Fore they think on't guess they'l sprout (Like a peach thet's got the yellers), With the meanness bustin' out. Wai, go 'long to help 'em stealin' Bigger pens to cram with slaves, Help the men thet's oilers dealin
Strona 145 - Then seems to come a hitch, — things lag behind, Till some fine mornin' Spring makes up her mind, An' ez, when snow-swelled rivers cresh their dams Heaped-up with ice thet dovetails in an' jams, A leak comes spirtin' thru some pin-hole cleft, Grows stronger, fercer, tears out right an...
