The very next day the captives were given labour which necessitated their presence in the ravine. During the noontide heat, while their guards were sleeping, they sang a Spanish roundelay to the accompaniment of the guitar. The princesses listened, and heard that it was a love ditty addressed to themselves. The ladies replied to the sound of a lute played by Zorayda, the burden of which was: The rose by the screen of her leaves is concealed, But the song of the nightingale pierces the shield. Every day the cavaliers worked in the ravine, and an intercourse was maintained between them and the no less captive princesses by songs and romances which breathed the feelings of either party. In time the princesses showed themselves on the balcony when the guards were wrapped in noonday slumber. But at length this desirable condition of affairs was interrupted, for the three young nobles were ransomed by their families and repaired to Granada to commence their homeward journey. They approached the aged Kadiga, and requested her to assist them to fly with the princesses to Spain. This proposal the old dame communicated to her young mistresses, and finding that they embraced it with alacrity a plan of escape was arranged. The rugged hill on which the Alhambra is built was at that time tunnelled by many a subterranean passage leading from the fortress to various parts of the city, and Kadiga arranged to conduct the royal damsels by one of these to a sally-port beyond the walls of Granada, where the cavaliers were to be in waiting with swift horses to bear the whole party over the borders. The appointed night arrived, and when the Alhambra was buried in deep sleep the princesses, accompanied by their duenna, descended from their apartments to the garden by means of a rope-ladder--all save Zorahayda, the youngest and most timorous, who at the decisive moment could not endure the idea of leaving her father. The advance of the night patrol which guarded the palace made it necessary for her sisters and Kadiga to fly without her. Groping their way through the fearful labyrinth, they succeeded in reaching the gate outside the walls. The Spanish cavaliers were waiting to receive them. The lover of Zorahayda was frantic when he learned that she had refused to leave the tower, but there was no time to waste in lamentations; the two princesses mounted behind their lovers, Kadiga behind another rider, and, dashing the spurs into the flanks of their steeds, the party galloped off at top speed.
