"It's the old lady. She's a bird of ill omen. I knew it the minute I saw her, this morning. Come out as soon as you can, Rog. I don't dare to be alone with her."

Roger grinned, but did not hasten his shaving. Ernest could be facetious. After all, the building of the plant was not Ernest's dream. Roger was shocked by the news of Austin's death, but the shock was not due to grief. Austin simply represented opportunity to the young inventor. A sudden fear was clutching at his heart lest now the plant would never be completed. Roger had learned much since his arrival in the desert. He had begun to realize that the desert fights ferociously any attempt to subdue her. He knew now that it was going to take much longer than the outside margin he had allowed to build the plant. If a driven well failed, he must try out the Prebles'. Perhaps Dick's knowledge of irrigation would prove to be sketchy and that water supply too would prove inadequate. He believed still that his plans for the plant itself would not have to be changed.

"I heard every word you two said," Mrs. von Minden's voice rose suddenly. "You needn't worry at all. I'll concentrate for you immediately after breakfast."

"In that case, we are ruined," Roger muttered, smiling in spite of himself, as he dropped the tent flap behind him.

The lady visitor was sitting on a bench beside the table in the cook tent, contemplating a cup of coffee and a plate of crackers.

"Was it your idea, madam," said Ernest, attacking a pile of pancakes some ten inches high, "that your husband would find you in this camp?"

"So the Yogis say," replied Mrs. von Minden.

"Why don't you fry yourself some cakes, Mrs. von Minden?" asked Roger.

"Part of my creed is never to prepare food for myself if it is possible to get some one else to do it. A complete inertia is a vital step toward Nirvana."

Roger grunted. "Then you'll never find Nirvana in this camp, I can tell you."
