"All O.K.," Bert assured. "I went in myself. The pipe is working. There's plenty of air."
"Ready!" Rita called. "Go!"
Graham ran toward their end like a foot-racer, while Paula darted up the high dive. By the time she had gained the top platform, his hands and feet were on the lower rungs. When he was half-way up she threatened a dive, compelling him to cease from climbing and to get out on the twenty-foot platform ready to follow her to the water. Whereupon she laughed down at him and did not dive. "Time is passing-- the precious seconds are ticking off," Ernestine chanted.
When he started to climb, Paula again chased him to the half-way platform with a threat to dive. But not many seconds did Graham waste. His next start was determined, and Paula, poised for her dive, could not send him scuttling back. He raced upward to gain the thirty-foot platform before she should dive, and she was too wise to linger. Out into space she launched, head back, arms bent, hands close to chest, legs straight and close together, her body balanced horizontally on the air as it fell outward and downward.
"Oh you Annette Kellerman!" Bert Wamwright's admiring cry floated up.
Graham ceased pursuit to watch the completion of the dive, and saw his hostess, a few feet above the water, bend her head forward, straighten out her arms and lock the hands to form the arch before her head, and, so shifting the balance of her body, change it from the horizontal to the perfect, water-cleaving angle.
The moment she entered the water, he swung out on the thirty-foot platform and waited. From this height he could make out her body beneath the surface swimming a full stroke straight for the far end of the tank. Not till then did he dive. He was confident that he could outspeed her, and his dive, far and flat, entered him in the water twenty feet beyond her entrance.
But at the instant he was in, Dick dipped two flat rocks into the water and struck them together. This was the signal for Paula to change her course. Graham heard the concussion and wondered. He broke surface in the full swing of the crawl and went down the tank to the far end at a killing pace. He pulled himself out and watched the surface of the tank. A burst of handclapping from the girls drew his eyes to the Little Lady drawing herself out of the tank at the other end.
Again he ran down the side of the tank, and again she climbed the scaffold. But this time his wind and endurance enabled him to cut down her lead, so that she was driven to the twenty-foot platform. She took no time for posturing or swanning, but tilted immediately off in a stiff dive, angling toward the west side of the tank. Almost they were in the air at the same time. In the water and under it, he could feel against his face and arms the agitation left by her progress; but she led into the deep shadow thrown by the low afternoon sun, where the water was so dark he could see nothing.
