There sounded then through that dark, breathless atmosphere a call steeped in wretchedness and black despair—the wail of that lonely owl, known to bushmen as “the mother of the moon.” Hal had heard many times when lost in the jungle of Panama what portent was in that cry, and he was thinking of it then when Rodriguez raised his head with effort.

“Ah, Señor Hal!” he cried in a terrified whisper. “’Tis ‘the mother of the moon’ and evil to me, for I have heard it. Ah, Señor....”

“Lie back, old fellow,” Hal soothed him. “Now there, calm down! I’ve heard about Old Wise Eyes too, but you don’t think I believe it, do you? Back in the good old U. S. we’d call that hokum pure and simple. Nothing to it. It’s just an old owl hooting his blooming head off because he hasn’t the brains to do anything else. In other words he’s yelling whoopee in Portuguese or Brazilian or whatever you spiggotty down here. I bet you haven’t understood a word of what I said? No? Well, I don’t blame you exactly.”

“I have not much time, Señor. I am weak ... the owl she....”

“Now for the love of Pete, Rodriguez, forget it!” Hal said, scolding him gently. “It tires you too much to talk about such hokum. Lie still and if you can only hold out perhaps Señor Carmichael will get help to us soon. He may have got a break and landed near some settlement.”

“Señor ... Carmichael?” asked the airman faintly.

“Sure,” Hal answered smiling, “that’s the fellow who went out in the chute—the fellow who came up with us. His name’s Carmichael. Oh say, I almost forgot, Rodriguez—of course you wouldn’t understand—Carmichael and I were only fooling you about him being my uncle. My real uncle couldn’t come—he backed out at the last minute. I met Carmichael at the field just before you came along. Understand?”

Rodriguez did understand—only too well. His ghastly face looked more ghastly than ever. He pressed desperately on Hal’s warm hand and sighed. Suddenly he released his own right hand and from forehead to breast devoutly made the sign of the cross.

“Señor Hal,” he gasped, “I am dying ... there is something I must tell....”
