Aleshores Joe i Huck van tornar a nedar, pero Tom no volgué arriscar-s'hi, perque descobrí que en dar una guitza a sos pantalons havia engegat l'enfilall de cascavells de serpent que duia a l'anca, i s'estranyava d'haver-se pogut escapar de rampes, per tant de temps, sense la protecció de aquest encís misteriós.
Then Joe and Huck had another swim, but Tom would not venture, because he found that in kicking off his trousers he had kicked his string of rattlesnake rattles off his ankle, and he wondered how he had escaped cramp so long without the protection of this mysterious charm.
