Low though his tone was, the words reached the ears of Donna Ana, the ever-present duenna, and she glared at him. This was no way for a brash young Americano to be speaking to the daughter of the great Don Fernandez. Jack caught the glance and laughed. He turned to the duenna and extended his hand.

"Farewell, Donna Ana," he said. "It's been such a pleasure to meet you."

The wizened old duenna was nonplussed. She did not know whether to resent this pleasantry or be gratified by it. Mechanically she accepted Jack's extended hand.

At that moment, Bob called to him. Jack turned. Mr. Hampton already had entered the airplane. They were waiting for him. Once more he seized Rafaela's hand.

"Remember," he said, so low that only her ears could hear his words, "you haven't seen the last of me."

She cast him an arch glance.

"Senor Jack is improving," she whispered. "He will be a courtier yet."

Then Jack climbed into his seat. A mechanic started the propeller, the machine began to bump over the ground, and presently it was in the air and climbing.

Bob spiralled upward until they were high above the ranch, and the figures below seemed little manikins. Jack believed he could distinguish Rafaela waving a lacy handkerchief, and leaned far over the side to wave in reply.

Then they were off, zooming through the air, straight as an arrow for the international boundary and the Hampton ranch beyond. The flight was brief. Bob covered the distance of 150 miles in considerably less than two hours.
