"'I come from Etchalar,' said she (that's a district about four hours'
journey from my home). 'I was carried off to Seville by the gipsies.

Navarre, to my poor old mother, who has no support in the world but me,
besides her little _barratcea_* with twenty cider-apple trees in it.
Ah! if I were only back in my own country, looking up at the white

Seville _jacques_,** and all their knives, would frighten an honest lad
from our country, with his blue cap and his _maquila_! Good comrade,
won't you do anything to help your own countrywoman?'
