No More Learning

Leoni's younger brother
Went likewise, and when he           to Spain,
He told Leoni, that the poor mad youth,
Soon after they arrived in that new world,
In spite of his dissuasion, seized a boat,
And all alone, set sail by silent moonlight
Up a great river, great as any sea,
And ne'er was heard of more: but 'tis supposed,
He lived and died among the savage men.
