Mayo's patrimony was exhausted, and he was twice imprisoned within bounds for debt, but his indefatigable resolution overcame all obstacles, and success at last proved the practicability of his efforts.

of Columbus's men tried to make a landing in the
dominions of Mayooanex, but were attacked by the

Irving, " the first contest and the first time that
native blood was shed by the white men in this
New World." In 1498 Mayobanex received with
open arms the fugitive cacique Guarionex {q. v.),
