Since Paul discovers his luck at predicting winning horses by riding his rocking-horse, the futility of the materialistic quest, and its lack of destination, are well symbolized in his frantic riding. Paul craves his mother's love, so he wants to win enough money to free her from indebtedness which consumes all of her attention. However, when Paul sets aside five thousand pounds from his winnings and arranges the family lawyer to send a thousand to Hester as a birthday present for five successive years, Hester, to his disappointment, doesn't show any suggestion of pleasure or gratefulness, instead, "her face hardened and became more expressionless, her voice cold and absent". Then she asks for the advance of the entire amount and spends them lavishly, getting the household mired in more debt. As a result, Paul can never satisfy his mother's insatiable appetite for more money. His quest for wealth by riding the rocking-horse will neither come to an end nor win him his mother's real affection. The rocking-horse embodies meaninglessness and futility in this stage. .
With mounting anxiety, Paul fails to make correct predictions for horse racing results, which imposes immense pressure on him. He becomes increasingly frail and intense, and in turn rides his rocking-horse more frantically and insanely than ever before. At this moment, the rocking horse symbolizes madness and self-destruction. On the surface, Paul madly urges the rocking-horse to give him an inspiration, but in fact he drives himself so hard that the moment he screams the name of the potential winner horse, he falls from the rocking-horse into unconsciousness. The pace of the rocking-horse, namely the process of Paul's self-destruction, is controlled by Hester's desire for money. The acceleration of her greed results in the speeding up of the rocking-horse and the collapse of Paul's nerve. In the end, Paul leaves eighty thousand pounds for his mother at the cost of his life.
