For a time Roger sat scowling with impatience, then Felicia's fear moved him and calling the child to him he began to tell her of the old swimming pool. The others listened and laughed and when Felicia begged for more, Gustav told a charming tale of his own Bavarian childhood. And he and Ernest sang together some tender folk songs which Felicia insisted on learning. While Gustav and Ernest undertook this pleasant task Charley and Roger talked.
At Charley's request, Roger brought out his blue prints and explained the plant to her. He felt his impatience lifting as he talked. Explaining his work always seemed to increase his critical vision. New ideas came flooding, and he pulled out his note book, feeling that after all the day was not entirely wasted.
So, in spite of the bitter taste of alkali in their mouths and its sting in their eyes, in spite of the breathless burning heat, the morning passed cheerfully. They even managed to satisfy their hunger with canned beef and canned brown bread. They had washed down the last of the unsavory lunch with the tepid, nauseously alkaline water from the olla when a gust of wind of tremendous proportions tore open the door flap and filled the room with a blinding swirl of sand. At the same moment there was a fearful crash from without, followed by the sound of breaking glass. Leaving Charley to refasten the door flap, the three men bolted toward the absorber.
The sand cloud was so dense that they could distinguish little until in actual contact with the edge of the trough. Then the trouble was obvious. A part of the sheet iron roof had blown off the engine house, and lay in a great twisted heap on the absorber. Roger immediately crawled under the trough. The heavy metal had pierced the floor of the absorber and oil was pouring out in a thin but steady stream. He pawed his way out hurriedly.
"Go shut the oil off, Ernest," he shouted, "and get pails to catch that oil. Why the devil did some one leave the valve open? Gustav, give me a hand with this mess. Why didn't we have sense enough to fasten it securely? If we don't move it, it may blow the length of the trough."
Roger plunged hastily up among the panes of broken glass, Gustav following. After a moment of effort the guilty mass of sheet iron was shoved over onto the sand. Just at the last a particularly vicious blast of wind twisted it violently against Gustav's bare arm.
"Du lieber Gott!" he roared. "Be careful yet!"
