While Barbara and her three friends at home were rejoicing over the message from Jefferson Worth telling them that he had secured the money needed to go on with the work, Willard Holmes was alone in his room in the San Felipe hotel.

Following the engineer's interview with Mr. Cartwright, he had passed through a stormy scene with James Greenfield and the words of the president of The King's Basin Land and Irrigation Company were ringing in his ears with painful monotony: "Discharged--discharged-- discharged!"

For the first time in his life the engineer had heard those words addressed to himself. He could not rid himself of the feeling that he had come suddenly to the end of his career.

All his life Willard Holmes had had back of him the powerful influence of his foster uncle. Positions and opportunities had come to him from the first without effort on his part. Notwithstanding the fact that his ability as an engineer was naturally of a high order and that his training was of the best, he had never been dependent wholly upon these things. Other and stronger considerations had always given him his place. For the first time in his life he faced the world of his profession with nothing but his naked ability as an engineer to speak for him, while his abrupt dismissal from the Company compelled him to realize with sudden force how over-shadowed his work had always been by outside influences and how dependent he had been upon them. He felt lost and bewildered, knowing not which way to turn. His future seemed a blank. He had been anxious and eager to get back to his work in the Basin. But he had not realized how much that work meant to him--how his plans, his dreams, his whole life work had become centered in the reclamation of The King's Basin Desert.

If his dismissal had come from anything connected with his work, he told himself, it would be different. He thought bitterly how he had struggled with insufficient equipment and inadequate makeshifts of every kind to hold the Company system together that the pioneers might have the water, without which the work of reclamation could not be done. He knew every stake and pile and plank and crack and patch in the whole system. He had learned the tricks of the river and was familiar with the conditions peculiar to the desert country. He knew the terrible danger of the flood season that was only two months away. He had planned and prepared to meet emergencies that would be sure to arise.

And now, because he had refused to deliver the settlers wholly into the hands of these New York capitalists, who cared nothing at all for the real work save as it could be made to increase their money bags, he was turned out. There was now no reason even for his return to The King's Basin. Why, he asked himself, should he go back? To see some other man doing his work? To watch as an outsider the development of the land? or perhaps--as was more likely--to stand idly by and watch its destruction?

But even as he told himself that he could not do that, he knew that he would go back; that, indeed, he must go. The desert called him-- summoned him imperatively;--the desert, and something else: something that was as mysteriously impelling as the spirit of the land; something that had grown into his life even as his work had grown; something that seemed to him now a part of his work from the beginning.

All that day the engineer avoided Greenfield and his eastern friends. In the evening he dined alone and after the meal sat alone in the hotel lobby with his back to the crowd, watching through the big window the life of the street outside--watching without seeing. Moodily he pulled at his cigar, his thoughts far away in Barbara's Desert where, unknown to him, Abe Lee on the buckskin horse was riding--riding--riding to save the work of Jefferson Worth.

His thoughts were interrupted by the voice of Jefferson Worth himself, who, seeing the engineer alone, had gone to him. Holmes, drawing another chair close to his, greeted Barbara's father with eager questions. "Have you heard from home? Is everything all right?"

The older man accepted the chair by the engineer's side and answered his questions by saying: "Mr. Cartwright instructed his New York bankers to wire this money to my account in Republic. I notified Abe to pay the men to-morrow and go on with the work."

It was characteristic of Jefferson Worth that he did not attempt to thank Holmes for his part in the transaction with Cartwright, but in some subtle way the engineer was made to feel his gratitude and appreciation. After a pause Worth continued: "I am going to start back to-night on the ten-thirty. When are you figuring on going back?"

The engineer smiled grimly. "I can't figure on anything definite just now, Mr. Worth. I might as well tell you, I suppose, that I am no longer connected with the Company."

The announcement did not appear to be unexpected to Jefferson Worth, but his slim fingers caressed his chin as he said: "I was afraid of that. Have you anything in view?"

Holmes felt that not only had Worth foreseen the situation, but that he had already set in motion some movement to relieve it. "No, sir. It came so suddenly that I have scarcely had time to think."

"I figured some time ago that the Company would not be able to hold you much longer," was the surprising comment. "The S. & C. has been looking for a good man to put down in our country for some time. Your experience on the river would make you particularly valuable to them under existing conditions. I told them about you. They have been holding off waiting developments. If I were you I would get in touch with them at once. You can go up to the city with me to-night. We will stop over and look into the proposition and then if it is all right and agreeable to you we can go on home together." Jefferson Worth seemed to understand perfectly the engineer's desire to return to The King's Basin.

Before Holmes could express his delight and gratitude at the unexpected relief, a call-boy, passing among the guests, shouted: "Mr. Jefferson Worth! Mr. Jefferson Worth!"

The banker opened the message, read it, then--without a word-handed the yellow slip to his companion. The engineer read: "Banks in Basin won't accept New York business. Can't handle pay checks. Abe Lee starting for San Felipe overland to-night. Have money and fresh horse ready. Barbara."

Holmes looked in consternation from the paper in his hand to Barbara's father. The face of Jefferson Worth expressed nothing. It was perfectly calm and emotionless, only the slim fingers were lifted to the chin as if behind that gray mask the mind of the man was groping, seizing, searching, examining eve............
