The telephone girl answered quickly: "Oh, how are you, Mr. Manning? We're glad you are back. Why, Mr. Williams was called down to Cabillo to make a deposition for the Washington hearing, several days ago. And they made Mr. Barton and Mr. Arles go, too. I'm trying to get them on long distance now. You came by the way of Albuquerque, didn't you? We tried to reach you in Washington, but couldn't." Jim groaned. His three best men were gone. "We didn't expect high water for a week," the girl went on, "or else----" "Miss Agnes," Jim interrupted, "call up every engineer on the job and tell them to report at once to me at Booth A. Whom did Iron Skull leave on his job?" "Benson, the head draughtsman." Jim hung up the receiver and stood a moment in thought. Iron Skull was now Jim's superintendent and right hand. His mechanical and electrical engineers were gone, too, leaving only cubs who had never seen a flood. Benson came running down the trail from the office. "For the Lord's sake, Benson, have you been asleep?" said Jim. Benson looked at the roaring flume. "She'll carry it all right, don't you think? I haven't been able to get in touch with the hydrographer for twenty-four hours. The water only began to rise an hour ago." "The poor kid may be drowned!" exclaimed Jim. He turned to the group of men forming about him. "We're in for a fight, fellows. This flood has just begun and it's higher now than I've ever seen the water in the flume. I'm going to fill the excavation with water from the flume and so avoid the wash from the main flow. Save what you can from the river bed. Leave the excavation to me." Five minutes later the river bed swarmed with workmen. The cable ways groaned with load after load of machinery. Jim ran down the trail, around the excavation and up onto the great block of concrete. The top of this was just below the flume edge. The foreman of the concrete gang was aghast at Jim's orders. "We may have a couple of hours," Jim finished, "or she may come down on us as if the bottom had dropped out of the ocean. See that everyone gets out of the excavation." The foreman looked a little pitifully at the concrete section. "That last pouring'll go out like a snow bank, Mr. Manning." Jim nodded. "Dam builders luck, Fritz. Get busy." He hurried into a telephone booth, even in the stress of the moment smiling ruefully as he remembered the complaint at the hearing. The booths _had_ been too well built. Jim's predecessor had been a government man of the old school in just one particular. Honest to his heart's core, he still could not understand the need of economy when working for Uncle Sam. "Have you heard from Iron Skull?" Jim asked the operator. "He ought to be here now, Mr. Manning," she replied. "I sent the car over to the kitchen." "You are all right, Miss Agnes," said Jim. "Tell Dr. Emmet to be near the telephone. I don't like the looks of this."
