Dusk was falling. From the bunk-house rose the tinkling notes of a mandolin; after a few preliminary chords, the player, a Mexican, began a love-song in Spanish. The distant chimes of Mission bells sounded softly on the evening air.

Jack and Echo sat down upon the steps of the piazza. Jack continued the strain of his thought, but in a more serious vein:

"Echo, I'm so happy that I am frightened."

"Frightened?" she asked wonderingly.

"Yes, scared—downright scared," he answered. "I reckon I'm like an Indian. An Indian doesn't believe it's good medicine to let the gods know he's big happy. For there's the Thunder Bird—"

"The Thunder Bird?"

"The evil spirit of the storm," continued Jack. "When the Thunder Bird hears a fellow saying he's big happy, he sends him bad luck—"

Echo laid her hand softly on the mouth of her sweetheart. "We won't spoil our happiness, then, by talking about it. We will just feel it—just be it."

She laid her head upon Jack's knee. He placed his arm lightly but protectingly over her shoulder. They sat in silence listening to the Mexican's song. Finally Jack bent over and whispered gently in her ear:

"Softly, so the Thunder Bird won't hear, Echo; tell me you love me; that you love only me; that you will always love me, no matter what shall happen; that you never loved, until you loved me."
