"I—help Sara!" exclaimed Jim. "Why I simply don't know he's living! It's my turn now. Sara has had his innings. Desert methods are perfectly simple and direct and I'm a desert man. You are here with me, Penelope, and you are going to stay with me."

Iron Skull was coming back. Pen laughed. "You and Sara ought to write movie dramas, Jim." Then she sobered. "Don't misunderstand my coming to the dam, Jimmy. I've learned a good many things since you left me in New York. One thing is that we can't cut our lives loose from other lives and be a law to ourselves. Another is that any responsibility we take up voluntarily ought to be carried to the end."

Jim looked at Pen curiously and his jaw set. She was several years younger than Jim, yet something had come to her in the years just past that made him in some ways feel immature. But Jim had not hungered and thirsted for eight years in starry solitudes with one memory and one dream to keep his heart alive, to relinquish the dream without a fight.

"Penelope," he said, "you don't know me."

Pen smiled. "I know you to the last hair in that brown thatch of yours, Still Jim." Then she turned to Iron Skull, who was eager to have her talk to old Suma-theek.

For some days Jim had no opportunity to continue Pen's education with himself as textbook. He was engrossed in watching and tending the flood. Old Jezebel enjoyed herself thoroughly for a week. She fought and scratched at the mountainsides, but save the chafing of purple lava dust from their sides she made no impression on their imperturbability. She ripped down the last pouring, contemptuously leaving tons of rock and concrete at the foot of the concrete section. She roared and howled and shook the good earth with the noise of a railway train tearing through a tunnel. And Jim laughed.

"If it wasn't for you, old girl," he told her one afternoon, "I'd go crazy with the flea bitings of the Enemy. But you, bless your wicked soul, are an honest part of the game. I was bred from the beginning to fight floods. You attack in the open, like an honest vixen. Wait till I get my clutches on you again."

As Jim finished this soliloquy with considerable satisfaction to himself, Iron Skull came up and laid a newspaper on his saddle horn.

"The newspapers are roasting you, Boss Still."
