, Amonasro.

"Father, what brings thee here?" she whispered.

"A grave cause, my child. Naught escapes my eye. I know thy heart. I
know that Radames loves thee and that thou art here to meet him;--also
that thou art in the grasp of this Princess, who hates thee."

"Alas, there is no hope," she cried, despairingly.

"That shall be as you may decide, daughter. Our people are waiting for
a signal to strike a blow at these Egyptians. Our backbone is not yet
broken. All that is needful for our success is to know by what road
our enemies will march in their next sortie upon us. That is for thee
to find out for us. Radames alone knows--and Radames loves thee," he
finished significantly.

"But since he loves me, how can I betray him, father?" she asked.

"Choose--between thy father and the man who is to marry
Amneris.--Or--" with a new thought he hesitated a moment--"or why
should Radames not leave these cold people for a fairer place and

of the trees as Radames approached.

"Art thou there, Aida?" Radames called softly.

"Alas, why should I meet thee," she sobbed, "since thou wilt marry
Amneris to-morrow?"

"Aida, I have come to tell thee there is hope," Radames whispered,
trembling with happiness. "The Ethiopians have again risen against us.
I am immediately to go forth to battle. I shall crush them this time,
and on my return the King will once more be generous to me, and I
shall demand then, that for my reward he free me from Amneris and give
me thee for my wife. When I have twice saved his kingdom, he cannot
refuse me."

"But do you not see that though the King should favour us, yet
Amneris's rage would be beyond all bounds?"

"I would defend thee."

"Thou couldst not. She is nearly as powerful as the King. If
